Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 4 Project Background

Project Description

As described in the original IPPD handout, a description for this project is as follows: Research and develop a business case and then build a working prototype for a charging station for mobile devices: cell phones, handheld GPS, iPODs, MP3, etc.

Jarden Consumer Solutions had an idea for a mobile device charger that could charge various products. It has been the team’s responsibility to gauge the interest of the product, determine the market of various mobile devices, and determine which devices could be covered efficiently without making the charger too complex. It is expected that the team cover 80% of cell phones and some other devices with a minimum use of wires and/or attachments. The team is in the process of completing research to determine the feasibility of this expectation.

Project Objectives

The team will not be reengineering an existing product. This is a new endeavor for everyone involved. It could potentially be used with some of Jarden’s current products, so it could possibly extend a product family. If not, it will create a new product line. This will partially depend on the feasibility of various designs. The final decision will be up to Jarden, but the objective is to help with designs and ideas. Only the basic design is expected, because incorporating the charger with a product would be more of a concern for the marketing team. The goal is to make the best product under the given specifications that will increase market share and connect the user back home.

The product is expected to charge various cell phones and other select mobile devices. The team has a goal of covering approximately 80% of the market for cell phones and smart phones, such as Treos and Blackberrys. The final product is expected to be easily upgradeable for expansion as the market continues to change and new phones with different charger connectors are developed. The product is expected to provide a trickle charge to one device to slowly charge the device during an overnight period.

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 5 Customer Requirements

Customer Needs

This product is being designed to appeal to the hospitality industry. Therefore, the customer needs are based on offering a valuable product for hotels. In turn, the customers purchasing the product (hotels primarily) must perceive the product to offer value to their guests. Keeping this in mind, the Charger Design Team and its customers have established attributes the final product should posses.

Highest Importance (NEED to be incorporated in final deliverable) - Value to customer - Liability (Product will not damage any device that can connect to it) - Number of compatible devices should be as high as possible - Attachment management system (if needed, should be as painless as possible) - Easy to operate - USB port

Medium Importance (If possible, should be included in design) - Cost - Durability (Able to withstand hotel room abuse) - Upgradeable (Ability to include new products as they are released)

Lowest Importance (Additional attributes to be in final deliverable, time permitting) - Compatibility with alternate inputs for use overseas - Size - Integration with existing products (Clock radio, lamp, etc.) - Rapid charge capability

House of Quality

In order to determine how the product specifications are related to the needs of the customer, a House of Quality chart was used – see figure 1. The customer needs/wants from the list developed above are listed on the left side of the chart. The product specifications are listed at the top of each column. At each intersection, a 1-5 scale is used to show how strongly a product spec supports a customer need. From this evaluation, the product specifications are ranked in order of importance of satisfying needs.

Hotel Guests’ Habits and Practices

One of the required objectives of the project was the validation of the need for the mobile device charger. Consumer trends indicate that people, especially business travelers, have an increasing need to be constantly connected to their work and home regardless of geographical location. It had been speculated by Jarden CS that business travelers constantly forget to take mobile device chargers when traveling. In order to verify hotel guests’ habits and current hotel practices to address any existing need, the team contacted hotels across the United States and performed online research.

In conducting online research of business travelers habits, the team visited several business and/or travel blogs and message boards. The findings, which provided some insight into current practices, were verified through phone conversations with hotels’ staff and managers.

Multiple hotels in major metropolitan areas across the country were contacted by phone. A full list of hotels and cities as well as a sample line of questions used can be found in the Appendix section.

The major conclusions obtained from this research support the previous assumption that there is a strong need for the mobile device charger. Although most travelers would likely still carry their mobile device chargers, the mobile device charger available in hotel rooms would fulfill a need in the event of forgotten charger.

The study concluded that currently hotels have a rudimentary system in place to address guests’ needs. Lost/forgotten chargers of previous guests are kept by hotel inbox at the front desk. Current guests may borrow any of the lost/forgotten chargers during their stay.

Patent and Literature Research

This project requires extensive patent research to ensure that the team will not be infringing on competitors existing patents. Using the United States Patent Office website, we were able to obtain all the patents relating to charging mobile devices. The

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 8 goal of the research was to find, read, and summarize the claims portion of the patents in order to create a design that would not infringe on the existing claims. The claims portion of the patent contains extensive amounts of information, but the most important information is contained in the first module of the claims section. Once the patents were read and summarized, the team was able to begin discussing design ideas for our prototype. Below is an example of a patent we were able to read and summarize:

Portable battery charger for a mobile device United States Patent 6583601 http://www.freepatentsonline.com/6583601.html

Claims: The following is claimed:

1. A portable battery charger for a mobile device having a rechargeable battery, comprising: battery contacts configured to receive a battery having a low-voltage value; a switching regulator coupled to the battery contacts and configured to draw the low- voltage value from the battery and convert the low-voltage value to a charger output; and a charger interface configured to electrically engage the mobile device and further configured to couple the charger output from the switching regulator to the rechargeable battery in the mobile device. A portable battery charger for a mobile device having a rechargeable battery includes battery contacts, a switching regulator, and a charger interface. The battery contacts are configured to receive a battery having a low-voltage value. The switching regulator is coupled to the battery contacts and configured to draw the low-voltage value from the battery and convert the low-voltage value to a charger output. The charger interface is configured to electrically engage the mobile device and is further configured to couple the charger output from the switching regulator to the rechargeable battery in the mobile device.

Benchmarking of Competitive Products

In order to assess the competition, the team conducted research on existing products in the market. Various products were found that contained similar charging methods. Many required the customer to buy the desired attachment for their phone. Jardens CS’ major competitor in this area is iGo. The iGo product consists of an attachment that connects to a first circuit which will then send a signal to a programmable chip stating

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 9 the desired voltage for the specific phone. There are also several universal chargers such as the Octopus that uses one electrical source with multiple outputs allowing the user to simultaneously charge several mobile devices.

Customer Perception

The main customers for the charging device are hotel chains. In order to verify consumer behavior assumptions and possible marketability of this new device, several hotels were contacted. Hotels in Atlanta, Boston, Chicago, Los Angeles, Miami and Gainesville were contacted by phone and asked to describe their habits and practices regarding mobile device chargers for guests.

Through the research, the team confirmed that there is indeed a need for a universal mobile device charger in hotels; the team also discovered that on average 2/3 of hotels have a rudimentary system in place to address guests’ needs. The current procedure is that currently hotels keep a box of chargers that have been left behind by past guests, when a new guest inquires about mobile device chargers the guest is directed to the aforementioned box and is allowed to borrow the charger during their stay.

Therefore, the creation of this hotel universal mobile device charger will aid in addressing hotel guests’ needs and depending execution of the final product may be an additional source of income for the hotel.

Mobile Devices

Jarden CS wishes to have a minimum number of attachments and still be able to cover at least 80 percent of the market for mobile devices. In order to address the issue the team researched and documented individual models of mobile devices along with the respective attachment and market share. The team also found the voltage and current needed to charge each phone which can be used to design circuit needed to charge the devices. Project Plan

Project Roadmap

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 10 The team has established a complete set of action items and deadlines to aid in the successful completion of the project.

Hardware Design Description

Overview and Objectives

The team has an objective of making a USB port attached to a clock. This port will serve as the charger base. The attachments that are to be plugged into the charger will have a protection device to ensure that the phones they are charging do not overcharge. The universal power supply and the phone attachment are the two forms of hardware that will be required in this project.

The two separate parts of the design will be integrated using USB attachments. This way the Phone Attachment segment can be used in any USB port and is not limited to the Universal Power Supply in this project. Adding this versatility to the Phone Attachment design will make it more valuable to the end customer allowing to use their attachment anywhere they have access to a computer.

Circuit Schematics and Operation

The following are schematics that have been designed by the team and will be used in the creation of the mobile device charger:

Universal Power supply / USB schematic

Figure 3

Overcharge protection schematic

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 12

The schematics displayed in Figure 3 and Figure 4 will work as follows:

The first part of the design is designing a Universal Power Supply. This circuit will convert the AC wall voltage to 5V DC and 500mA using a typical power supply design. Staying consistent with the notion of versatility, these voltage and current values can be attained from other USB ports also. This output will go to the attachment’s protection circuit.

The overcharge protection circuit has the job of reading the current and voltage levels of the battery that is being charged. If the battery has been properly charged, the circuit will need to switch off the connection that is charging the circuit. The Universal Power Supply or USB port will still continue to provide its steady 5V and 500mA, but this will no longer flow through the phone adapter and on to the battery. If the battery has not been fully charged, the 5V and 500mA from the USB will be forwarded through protection circuit and on to the battery, allowing it to charge.

USB 2.0

USB Implementers Forum, Inc. is a non-profit corporation founded by the group of companies that developed the Universal Serial Bus specification (www.usb.org.) The USB 2.0 specification, published by the USB-IF, defines standard protocol and procedures to work with USB.

The design described in this project does not conform to this protocol. The standard says that all USB devices must power up drawing no more than 100 mA of current. If the device requires more, then it is to be requested from the host in increments of 100 mA up to 500 mA. Like the Phone Attachment circuit described in this report, reading lights, fans, mug heaters and other miscellaneous USB powered attachments use more than 100 mA without requesting it from the host. In practice, most ports will deliver the full 500 mA or more before shutting down (from wikipedia.)

Graph 1shows the voltage between the base and emitter (top plot), the current of the circuit (middle plot) and the voltage between the base and collector (bottom plot). As the voltage of the cell phone battery increases during the charge, the current slowly reduces and eventually cuts off to prevent overcharge.

Hardware Product Design Specifications

The overall goal is a mobile device charger. This charger will begin with the female USB A port built into the clock radio. The USB will receive plug-ins from the attachments. The Phone Attachment will have multiple parts. The male USB A cord will

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 15 be connected to an overcharge protection circuit to regulate the flow of the charger. This circuit will then be connected to the piece that connects to the phone, which has its own circuitry that connects to the battery.

The Universal Power Supply will convert power from 120 VAC to 5 VDC. To do this, a step down transformer will decrease the voltage down to about 10 VAC. A rectifier and voltage regulator will then use this AC signal to provide a steady 5 V output. The capacitor before the voltage regulator will provide a steady voltage to the input. The capacitor after will ensure that the output voltage does not spike for any reason.

Within the overcharge protection circuit we simply have resistors, a BJT, and a capacitor. The circuit will receive a 5V, 500mA input from the USB port. A voltage divider currently made up of 20k and 30k resistors brings the voltage down to 3.6V as it reaches the base of the transistor. The output will be approximately 4.3V to be sent to the phone’s internal charging circuit, only when the phone isn’t already fully charged. If it is fully charged the circuit will disconnect and no charging will occur. The resistances are likely to vary as we work on achieving ideal conditions to stop the charging when the phone has been fully charged.

External Interface Specifications

This section describes the specifications that define how the charger will be connected and interface with the user.

User Interfacing

In striving to fulfill the customer requirements for this project, the device has been designed to be user-friendly, easy to operate and to potentially eliminate liability concerns.

From the user’s perspective, the interface consists of three parts and two steps. The user will attach the adaptor end of the phone attachment cord to their phone and the other end of the phone attachment will be connected to the USB port in the charging device. The user interface with the Universal Power Supply will be very similar to their interface with their current mobile device charger. A simple graphic explanation is included in figure 7.

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 16

Figure 7 In addition, it is recommended that a simple display card with instructions and illustrations be available for the users who require assistance with use of the product.

Operating Environment

The Universal Power Supply must be able to operate in a hotel environment. The following conditions are taken into consideration. - Temperature - Humidity - Frequency of Use Temperature

Although ambient temperature is between 68 and 77 degrees Fahrenheit, a wider range must be considered in the event of mis-settings of the air condition system. The prototype will function in a room with temperature ranging from 50 to 90 degrees Fahrenheit. Humidity

Ambient humidity of 25 to 95% RH will be considered in the development of the prototype. This range will be used to account for changes in weather throughout the year. Frequency of Use

Since durability is a priority item for Jarden CS, the prototype developed will allow for daily use of the product. Maltreating of the product will also be considered. Testing of maltreating is considered under the Quality and Reliability Plans section of this report.

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 17 Quality and Reliability Objectives and Plans

It should be noted that an extensive testing procedure for reliability is not needed in this case, a standard check for basic maltreatment of the product will be conducted in order to ensure the design is reliable when put into the designated application. The quality and reliability of the charger relies on the quality and reliability of the different components and sections of the product. The following plans have been designed for testing reliability/quality:

Product Maltreatment Test

Testing the durability of the prototype when integrated into the desired application. This will be done by various tests such as: Pulling cord when phone attached to prototype, forcing the wrong attachment into the phone, and the part life must be extended over a period of five years.

Industry Standard Procedures

It is recommended that Jarden CS test the power supply of the final product for their desired quality performance. The industry standards for power supply operation, including testing the following areas: - Load & Line regulation - Transient performance - Over-voltage response & shutdown indicators - Stress & Overload capability - Temperature performance - Brownout performance

Materials

Preliminary Bill of Materials

The Bill of Materials (BOM) shown in figure 8 lists all the individual components that form the charger and illustrates the order in which they will be assembled. About 90% of all these components are considered to be standard parts and will be purchased from the most convenient manufacturer. The only items that the team has not been able to identify a vendor for are the mobile device adaptors.

Assembly Process

The engineering team has efficiently completed all the previous deliverables for this projects by treating them in an individual fashion, all the different components will eventually be assembled together to form the cell-phone charging prototype.

The Prototype is divided into two parts: DC supply, and Attachment. The DC Supply takes in AC from the wall and converts it to DC through the circuit assembly shown in the figure below. The DC voltage is output at the USB receptacle.

Figure 9

The attachments will have male USB connector in one end and cell-phone connector on the other. The USB connector is followed by charge termination circuit and then connected to Mobile Device connector through a wire.

Figure 10

Testing

The prototype DC supply will be tested for the output voltage and current. Then, the functionality of the charge termination circuit will be tested by connecting a working cell-phone to the charger, and leave it connected for long period of time. When the

Charger_SLDR Created on 12/1/2006 Team Charger Revised on 12/13/2006 20 battery reaches predetermined voltage limit, the current going into the battery should be zero.

The functionality of the attachment will also be tested with the USB port on the computers.

Parts, Quantity, and Cost

The parts necessary to build the prototype are listed in Table 1, along with quantity required and their costs. The estimated cost for the Universal Power Supply is of $11.76 and of each individual attachment is of $1.94. The number of attachments necessary will be recommended by the team at the completion of the project but will be at the discretion of Jarden CS.

Product Verification Plans

The prototype that will be built does not contain any programming conducted by the team; therefore, no software test or hardware/software integration test will be conducted. The individual components as well as the system as a whole will be tested to ensure that the product functions as stated by Jarden in the desired specifications. The testing procedures that will be done are as follows:

Test Battery Condition

Battery condition is first checked. To do this a short pulse of current will be sent to the battery while measuring the resulting voltage response. From here much of the details of the battery can be determined.

Charge Regiment Test

Since output must be a constant 5V-500mA, the product will run for an allotted amount of time to confirm the constant flow of current and voltage into the battery.

Charging Termination Test

Once the latter test is verified, the prototype will be subjected to various tests in order to determine the termination feature of our product. Such tests may include increasing ambient temperature, which increases battery temperature, battery reaching full charged state, etc.

Discharging and Charging Test

The charger will be tested with a fully discharged battery on a phone that is shut-off in order to determine its charging. It will also be tested with a phone that is left on while charging. This allows for the circuit to be turned on once battery is detected to be depleting and turn off when full battery charge is reached.

Adapter Power Down Test

Time permitting; adapter power down test will be completed. Testing will be conducted in order to ensure that if the product is integrated with an existing product, when the host product is shut down there will not be any load present in the charging port. This will test the disconnect relays for isolating the adapter port. Project Concerns

Attachment Management

The team was not able to find a source for the cell-phone, PDAs and mp3 player connectors needed to connect the charger to the devices. The team was successful in documenting the devices and attachments by model, but data on market share of individual models was not found and resources have been exhausted. The team has proceeded with prototype development and will incorporate as many devices as possible; the team will also develop an alternative for devices not covered by the prototype. Recommendations

The team would recommend that all parties involved read the entire report presented and evaluate the progress and the plan of the team. The team feels very confident about the future of this project and believes that they are taking all the proper steps in order to deliver the prototype on the declared submission day. The team has been deeply involved in researching the components for optimizing functionality and cost and will be, in a very enthusiastic fashion, conducting all the different experiments and tests required to prove the functionality of the product. Once again, if the Company sponsor or any other parties evaluate the contents of this report, project objectives, and/or the project schedules as unrealistic or off track, the team would appreciate any guidance toward setting realistic goals. Otherwise, the team recommends all parties to approve this report so that the team can move on to the final phase of this project in order to begin the construction of the prototype chargers.
