Team Vision for Problem Definition Phase

Our vision for this phase was to organize and prepare ourselves for the work to come. What we wanted to achieve at the end of this phase was a clear, well defined definition of our problem based on a prioritized list of customer requirements, use scenarios, required deliverables, and design constraints.

Fighting through setbacks like lack of man-power and trouble contacting our client, we were able to create to create our customer requirements list, deliverables, a solid understanding of some possible use scenarios, and design constraints. All in all, we used these to come up with a good definition of our problem, but one that may need refinement down the road.

Project Summary

A Smart Brake Temperature Monitor (BTM) Probe is a device that makes use of a thermocouple to sense the temperature of the brakes in an aircraft. The device should be able to communicate wirelessly over BlueTooth to an Android or iOS device and also be compact and lightweight. Making the device wireless eliminates the need for expensive wiring and a heavy harness the the current BTM probe requires.

The goals of this project are to understand the current product and utilize what it already does well but remove the need for wiring and a harness by making it BlueTooth and Android/iOS compatible. The expected deliverables are a working prototype along with the design itself including drawings, schematics, BOM, software, source code, etc. and will be designed with the intention of this one day being a manufactured product.

Use Cases

Below are some potential use scenarios for the Smart BTM:

Use Scenario 2

Use Scenario 2

Project Goals and Key Deliverables

The overall goal of this project is to create a highly accurate temperature sensor to be used on aircraft brakes wirelessly. This sensor must be compact and lightweight and be able to seamlessly transmit data to an Android/iOS smartphone.

Plans for next phase

Our plan for the next phase is to get done everything we need to begin thinking about our detailed design. What that entails are first completing our benchmarking and a preliminary analysis of our risks then taking our list of requirements and consolidate them into various functions that our product must perform. That functional decomposition will allow us to brainstorm various design concepts from which we will choose the most feasible based on some exhaustive engineering analysis. With this work done, at the end of this phase we will be in a great place to start detailed design.
