THE CHROMATAP PROJECT PROPOSAL | Executive Summary 5 Technologies Incorporated neoSpectra

Executive Summary Guiding Principle: Create safe and vibrant products that enhance the quality of life and fulfill the needs of customers at the lowest cost possible

Can you tell what temperature this water is?

I certainly can’t. Now w hat if I told you that it w as hot enough to severely burn your six year old w ithin seconds, and possibly you as well? Today, in most Canadian homes, the hot water temperature can reach up to 60°C (140°F), which can cause third-degree burns in most adults in less than six seconds. Young children, elderly people, and people with disabilities are even more vulnerable to these serious burns because of their thinner skin and slower reaction times. One study from SafeKids Canada estimates that over 50,000 children ages 0-6 are adm itted to em ergency room s each year for treatm ent of hot tap w ater burns (Children’s Safety Association 2006). For children, hot tap water injuries are the most common form of scalding injuries, and these burns often results in a much larger surface area than any other scald. Not only do the children need to suffer agonizing treatment, they may also be traumatized emotionally by the pain. Elders who sustain hot tap water scalds are also at a 50% increased risk of dying from their burns compared with other scald injuries requiring hospitalization (Mezei and Stanwick 2004).


THE CHROMATAP PROJECT PROPOSAL | Executive Summary 6 Technologies Incorporated neoSpectra

Now what if the water stream would change color depending on the temperature, giving you and your children a visual indicator, making it convenient for you to gauge water temperature, and easy for them to learn about hot water safety? This is exactly what our company, NeoSpectra Technologies Inc., plans to implement with the ChromaTap, a low-cost and easy to install faucet add-on which will light the water different shades of red for hot and blue for cold. Existing solutions to this problem include hot water cut-off devices and turning down the hot water temperature. Both of these solutions do not allow access to hot water when it is truly needed, and are very expensive compared to ChromaTap. The similar solutions currently under development are based on the assumption that you will be willing to replace the entire faucet fixture, a costly and time consuming endeavor. Only ChromaTap provides an easy to install safety indicator which also allows for convenient access to hot water. In addition to its merits as a safety feature, the visual effect of the lighted water turns the ChromaTap into a stylish and marketable household product. We also plan to develop a shower version of the ChromaTap which will help prevent you and your children from suffering hot water related mishaps in the shower. Our company is made up of four senior year Engineering Science students in different disciplines. Our combined expertise includes skills in project management, CAD design, electronics design, and power generation systems. This proposal also highlights the entire development process of the ChromaTap, which details all the immediate steps required to conduct a successful commercial launch in February 2008. For the purposes of our ENSC 440 project, we will deliver a total of eight modular-based designs. Six of these will be the shower and faucet versions for each of the three proposed power systems (battery, solar, and hydroelectric). The two final prototypes, one for the shower and one for the faucet, will be built around the power system we deem to be the best in term of size, power, reliability, safety, cost, and ease of use. The budget for the thirteen-week project is tentatively set at $420, which includes $70 in a contingency fund. By winning the Ken Spencer Business Plan Competition with the ChromaTap Business Plan, we have already obtained most of the project funding, and we are confident that we will be able to raise additional funding for the project given its promising commercial potential.


THE CHROMATAP PROJECT PROPOSAL | Introduction 7

Technologies Incorporated neoSpectra

1. Introduction Household safety is a growing concern for parents with young children in their care. Thousands of children are injured in the home each year, and the most common injuries among children are burns and scalds. In particular, hot water is a common hazard because it is easily accessible by children, who can suffer serious scalds from as little as one second of contact. The ChromaTap is an easy to use and affordable solution to the problem of hot water burns in the home. It will address this problem both at the sink and in the shower, by lighting the water stream different intensities of red for hot and blue for cold. This provides a reasonable visual indication of water temperature for the user without compromising the availability of hot water, or requiring costly installation like the other current solutions available. The objective of our project is to evaluate different design solutions for the ChromaTap (both faucet and shower versions) for engineering merit and commercial potential, focusing on the categories of size, power, reliability, safety, cost, and ease of use. To do this, we will explore three alternate methods of powering the ChromaTap: battery, solar, and water power. In this proposal, we will discuss the system overview and proposed design of the ChromaTap, along with competing and alternative design solutions. We will also touch on our company profile and consider the organization of the project team. Lastly, we will review a detailed project plan with a budget and schedule for ChromaTap development. Gantt and milestone charts are included for easy reference.


THE CHROMATAP PROJECT PROPOSAL | System Overview 8


2. System Overview

Figures 2.1 and 2.2 depict a simple demonstration of the ChromaTap’s operation. The ChromaTap is extremely easy to use: no direct user interface is required for normal operation. The user can easily install the ChromaTap faucet attachment (or a showerhead replacement) in less than a minute. After a successful installation, the device automatically turns on when the user switches on the water tap. Then, the visual indictor of the ChromaTap outputs an appropriate lighting effect: red for hot and blue for cold. The intensities of the lighting are continuously updated according to the temperature level of the water. The operating temperature of the ChromaTap ranges from 0°C to 60°C. When the user switches off the tap, the device automatically turns off.

User can easily install the

ChromaTap in less than a minute.

3. Current Design Solutions

Currently, there are a few options for managing hot water in the home, ranging from anti-scalding devices to intelligent faucet installations. Although most solutions provide a direct way to control and restrain water temperature, they are hard and expensive to install for typical users. Details of the currently available design solutions are discussed in the following sections.

3.1 Water Heater Adjustment In order to minimize the risk of hot water tap burns, some homeowners have been manually adjusting hot water tanks to below 49°C (120°F), a temperature considered safe for use, even for children. However, lowering the temperature on the hot water tank can be dangerous because the stored water may attract harmful bacteria colonization. Further, hot water is not readily available when necessary, posing an inconvenience to the user. Although this method does provide safety for the children in the home, it is not a practical solution for everyday water use.

3.2 Anti-Scalding Devices Anti-scalding devices, or thermal master mixing valves, blend hot and cold water coming out of the water tank such that it does not exceed 49°C (120°F). These devices have become quite common in households. In fact, anti-scalding devices have even become mandatory for installations of new water heaters in some jurisdictions such as Ontario. Anti-scalding devices are only effective at preventing temperatures from reaching a predefined cut-off m ark. How ever, young children’s skin can burn at tem peratures below that standard cut-off mark. At temperatures below 49°C (120°F), anti-scald devices are unable to provide the user with any sort of protection or warning about hot water. More importantly, anti-scalding devices are expensive and require installation by a professional, a clear disadvantage compared to a low-cost add-on like the ChromaTap.

3.3 Thermostatic Temperature Controlled Faucet & Shower

Figure 3.1 : Hansgrohe Solaris ThermoBalance II– Cost $850 (Home Depot, 2006)

A temperature-controlled shower and faucet offers a direct method for the user to input their desired water temperature. However, it is often expensive, with prices ranging from $200 to $1500 dollars. Also, if the user mistakenly sets the wrong temperature or accidently changes the temperature without knowing, the user will receive no other direct warning about the temperature before touching the water. Figure 3.1 illustrates a sample product from Hansgrohe, where the user can preset the water temperature through the dial on the faucet handle.

3.4 Faucet Replacements

Figure 3.2 : Hansa Hansacanyon (Hansa Detuchland, 2006)

Similar to the idea of the ChromaTap, companies such as Hansa and Delta Facuet have developed

systems that provide temperature-sensitive lighting to the water stream as shown in Figure 3.2.

However, these fixture systems are complete replacements for conventional household faucets, and as

such, require considerable time and expense for installation. They must also be connected to a nearby

power source in the room. Given these considerations, this upscale replacement is only appropriate for

high-end users who are looking for style and fashion, rather than parents who are looking for an

affordable safety device to be installed on multiple faucets for their children.


THE CHROMATAP PROJECT PROPOSAL | Proposed Design Solutions 12


4. Proposed Design Solutions

The ChromaTap, our proposed solution to the hot water tap problem, is an easy-to-install faucet attachment that provides an instant visual indication of the water temperature by turning the water stream to blue or red at various intensities. The natural association between red and hot or between blue and cold offers a much quicker feedback that most people can easily comprehend, especially children. A showerhead replacement with temperature-sensitive lighting is also proposed to help protect children and elders in their showers. ChromaTap shines over the current design solutions. It has the advantage of being affordable and easy to install, while providing a colorful and a continuous visual cue for water temperature. It also allows safe access to hot water when needed. ChromaTap aims to be safe, affordable, and easy to use. To achieve these goals, we will be choosing ChromaTap designs based on a balance of size, power, reliability, safety, cost, and ease of use. Figure 4.1 outlines the general system architecture of the ChromaTap for both bathroom faucet and showerhead variants.

Figure 4.1 : ChromaTap System Architecture Overview




4.1 Power Generation Module The power generation module is responsible for generating and managing a stable power source for the entire system. We propose three design alternatives for the power generation module: a battery-powered module, solar-power module, and hydroelectric module. The battery-powered module, which uses the conventional thin-profile battery as the power source, will be relatively quickly developed. The solar-powered module, which poses several engineering problems, such as power storage, will require a longer design time. However, most of our efforts will be devoted to the most challenging design - the hydroelectric module, where mechanical energy from the input water stream is extracted. The three proposed implementations will be evaluated and analyzed during the project to choose a suitable configuration for the final product.

4.2 Input Conversion Module The input conversion module activates the entire ChromaTap system when the user turns on the faucet or the showerhead. The module then gathers the temperature information from the water stream and converts this information into an appropriate format for the Control and Processing Module to evaluate. Modification of the input conversion module may be necessary when connecting to different types of power generation modules.

4.3 Control and Processing Module The control and processing module assesses the input temperature information and generates an appropriate output to the output conversion module. We may also implement a power management control system to conserve power.

4.4 Output Conversion Module The output conversion module receives the output information from the control and processing module and converts this information into an appropriate visual indication for the user. The faucet and showerhead variants may have different output configurations and methods.

4.5 Safety Module The safety module ensures the safety and reliability of the device both mechanically and electrically. The module may be closely integrated with other system components. We will design a robust and safe device that will satisfy various international safety standards and codes. We will also perform reliability testing to counter system failures such as water leaks, power shorts and surges, and corrosion.




4.6 Casing and Mechanics Module We will design two types of casing modules: one for the faucet add-on, and another for the showerhead. Different power modules will also require different casing designs. We will also perform detailed mechanical simulation and testing to ensure the usability and reliability of the device.

4.7 Project Constraints and Limitations Our major constraint in completing this project is the lack of experience in mechanical design. We plan to use outside sources to help us with this limitation. Secondly, time and funds are limited. No production prototype can be produced, given the short thirteen-week time allotment and tight budget constraints. For the purpose of satisfying ENSC 440 Project requirements, we will only complete the proof-of-concept prototypes with mockup mechanical casing, and a preliminary production design layout. We will discuss the project deliverables in Section 7. Over the long run, our company is continuously seeking further funding from external sources and venture capitalists to ensure our ChromaTap development can be completed, and is ready for commercial launch by the first quarter of 2008. We also propose a long-term development plan for the ChromaTap in Section 7.


THE CHROMATAP PROJECT PROPOSAL | Source of Information 15


5. Source of Information

In terms of the project research and design, we plan to draw on information from course textbooks, as well as books on product design, solar power, and water power. We will also use the Internet to source information on these and other topics relevant to our design. We also plan to use the Internet for parts sourcing and evaluation of different components. We also have a group of individuals who we have selected as typical ChromaTap customers, family friends who have relatively young children at home. We will be considering their input throughout the design process, and this information will factor into our final design decisions. Further, for electronics design and implementation, we are lucky to have access to Dr. Ash Parameswaran, who can advise us should we run into electrical design issues. Dr. Bozena Kaminska will also be a valuable resource for materials selection and for learning effective ways of estimating MTBF for our different configurations. Furthermore, we also have industry contacts from our various co-op work terms who can advise on electronics and mechanical design. On the business side, Mike Volker, a lecturer and entrepreneur, can assist us with analyzing the marketability of different configurations, which will be another factor in selecting our final design.


THE CHROMATAP PROJECT PROPOSAL | Budget and Funding 16


6. Budget and Funding

6.1 Budget Table 6.1 outlines the estimated expenses incurred for the completion of the ENSC 440 Capstone Project. The budget covers the development costs of all proof-of-concept prototypes. A contingency fund (20% of total expenses) has been imposed for unexpected expenses.

THE CHROMATAP PROJECT PROPOSAL | Budget and Funding 17


6.2 Funding Since the anticipated budget for the early stage of development is small, the risk of insufficient project funding is minimal. In fact, most of the funding has already been obtained through the cash prize from the 2006 Ken Spencer Business Plan Competition, where our ChromaTap Business Plan was awarded a first place standing. Additionally, we will be seeking funding from the ESSEF (Engineering Science Student Endowment Fund), and the Wighton Development Fund. In the event of insufficient funding or a budget overrun, all team members have agreed to share the financial responsibility equally. Through careful bookkeeping, we will ensure all accounts are recorded and each of our members will get proper reimbursement. Over the long run, we will continue to seek investors and venture capitalists in funding our company and the commercial development of the ChromaTap.


THE CHROMATAP PROJECT PROPOSAL | Project Planning 18


7. Project Planning We expect the full development cycle of the ChromaTap project to be complete by Mid-February, 2008, at the latest. Our goal is to deliver a viable commercial version of the ChromaTap. The ChromaTap project is divided into four main phases: task clarification phase, conceptual design phase, embodiment design phase, and detail design phase. Through the use of the incremental design process, the course of product development is broken down into increments to ensure all levels of design problems and details are addressed in a systematic manner. Each development phase may contain one incremental process with specific objectives and level of design details. We could develop one or more hardware design builds within one incremental cycle. This process allows us the freedom to systemically introduce new technologies or redesigned components in successive hardware builds. To complete one hardware build cycle, we will go through the typical development and testing cycle (see Figure 7.1), which results in deliverables that satisfy the intended requirements for each increment.

THE CHROMATAP PROJECT PROPOSAL | Team Organization & Team Profile 29


8. Team Organization & Team Profile

The ChromaTap Project Development Team is comprised of four talented, creative and knowledge engineering undergraduate students from Simon Fraser University: Mr. Scott Chen, Mr. Jacky Cheng, Mr. Derek Pang, and Mr. Jim Wang.

8.1 Team Organization We will impose a flat team organizational structure to encourage a free, interactive, and independent environment. Everyone is equally responsible for the success or failure of the project. Different members will be responsible for the development of different system modules according to their own interests and strengths. However, such an assignment of responsibilities does not limit the work of each member to just a particular com ponent. M em bers are expected and encouraged to w ork, assist and review each other’s system designs. Not only can team m em bers exchange ideas and cover each other’s w eaknesses, but they can have a better overall understanding of the system. All of these advantages promote an efficient workflow and minimize integration bottlenecks. Concise communication and group dynamics are crucial to keep the project running and on schedule. A regular weekly meeting is scheduled to update the overall project progress and discuss on major project issues. A group forum and file repository website (http://kickme.to/ensc440) has also been setup to manage files and documentation for the project. It also encourages members to exchange comments and feedback, and post project-related information and references. Further, online group meetings, instant messaging, emails, and telephones are other communication channels that bring us together when we are working away from home.

10. Conclusion

Can you tell what temperature the water is now?

W ell, if you printed this docum ent in black and w hite, you probably still can’t. But this picture, w ith the water glowing red, gives a simple idea of the visual effect that could be created in your water by installing a ChromaTap on your faucet or on your showerhead. To tell the temperature of the water, children, elders and adults are no longer in risk touching the scotching hot water. Given the demonstrated need for ChromaTap, the success of product will largely depend on three major design factors: affordability, reliability, and ease of use. Based on these three principles, we are dedicated and committed to deliver the simple and vibrant ChromaTap on schedule. Our careful project planning and talented engineers also guarantees the ChromaTap will encompass the best quality and reliable possible. If you are further interested in the ChromaTap, please contact us for a copy of the business plan, which includes a detailed marketing, operations, and financial plan.
