Product Launch

Conceptually, the product works, but needs key improvements for Build 2.1


Teamwork

No major issues encountered


Modularization allowed independent work and group integration

Primary responsibilities not key, members helped where they could


System Overview and High Level Design



System Overview

Implementing this system with a modular design was very effective


User can easily install the

ChromaTap in less than a minute.

System Overview

Allowed us to build one control circuit module, saved costs

Notice solar is not included in the power options, more detail on this later

Efficiency improved because modules assembled independently



Solar Power

Average use: 20 seconds per use, 15 times per day, 3 minutes in total

Average power consumption 30mW, Approx. energy needed 5400mJ per day

Power produced by Sanyo SA3515S4: 0.05mW(room), 0.4mW (direct)

Energy produced: 24mJ per day (room), 192mJ per day (direct to light) Assuming lights are on for 8 hours

Surface area: 5.63cm^2 per SA3515S4, need 600 solar panels (or 75 )

Non-feasible due to the size and cost constraints

Other power implementations will be discussed as part of the project demo

Conclusions

Expecting better results from thermistor in prototype

Even faster response times can be guaranteed by better processes

Brightness was also an issue, lens was used in shower to improve focus

Lens also implemented in the final faucet design, but not in prototype

Device is currently not effective enough to serve as a true safety indicator


Modular design was very effective for development

Varying pulse frequency based brightness works well for power savings


Conclusions, continued

Inclusion of blue LEDs required a higher than expected voltage

Final revision water power was much more effective than expected

Solar power is not feasible given typical lighting conditions


Water power generation went through several revisions

Product has been proven to be highly marketable, assuming issue resolution

LEDs require focusing for effectiveness beyond a short distance


Moving Forward and Key Learnings

Additional lens experiments and parts sourcing to improve brightness

Feasibility of miniaturization design and cost of water generation

Nothing goes exactly to plan; things go wrong at the worst times

Part count and power optimization


Re-evaluate functional specification and product applications

The dollar store has a lot of useful parts available at reasonable prices

Some water sealing materials like glue actually conduct
