Team Vision for Problem Definition PhaseThe team worked on a number of tasks to better understand the objective of the project. These tasks included:
- Exploring Use Scenarios
- Conducting the Customer Interview
- Defining Customer Requirements
- Establishing Engineering Requirements and Constraints
- Constructing a Project Plan
In order to work well as a team, the group agreed on four team values and created a rubric to evaluate individual team member performance in each of these categories. Team norms can be found here.
Team roles, tabulated below, were also established.
|Project Manager - Scheduling/Facilitation||Natalie Hurd|
|Project Manager - Design/Lead Engineer||Nicole Bureau|
|Communications Lead||Abdul Alshaikh|
|Industrial Designer||Gina Colosimo|
|Systems Design and Edge Coordinator||Isaac Arabadjis|
|Software Modeling||AJ Longabucco and Connor Boudreau|

Use CasesA typical use case workflow chart was developed to assist in the understanding of how the products will actually be used. By breaking down the steps when using the devices we are able to consider finer details such as storage when developing a working prototype.
Project Goals and Key Deliverables
We are looking to create a product that is:
- easy to use
At the end of this course we will have:
- designed and built a working prototype
- completely filled our Edge website will all details relevant to the work we did on the project
- generated engineering drawings and documents for the design of our prototype
- participated in Imagine RIT
- documented our progress through a comprehensive technical paper
- summarized plans for a manufactured design and for design improvements
- created a visually appealing and informative poster summarizing our project

Engineering Requirements (Metrics & Specifications)
A link to the working requirements document can be found here.
- Final market cost of $500-$1,200
- Meets requirements for attachment to Class I Medical Devices
- Must not infringe on any current patents
- Senior Design time frame
House of QualityAfter prioritizing and generating the customer needs the engineering requirements were developed and the first phase of the QFD was conducted. It turns out based on the largest relative weight (of 6%) the engineering metrics of interest are:
- Attachment accommodates at least 75% of mobility aids with front vertical bars
- Ability to attach to wheelchair bar or walker capture object traveling on the ground
- Ability to capture \ throw balls
- Adjustability of Catch and Launch the transverse plane
- Adjustability of the catch and launch in the sagittal plane
- Capture objects traveling on the ground
Among those metrics which had equal large weights (of 6%) it was decided that the primary focus is capturing objects traveling on the ground. Therefore, the lower extremity device and attachments are the primary focus.

Plans for next phaseIn order to be fully prepared for the next three weeks of the project, we put together a project plan for Cycle 2. The plan outlines each individual task we will be completing in the next three weeks, as well as estimated durations for each of the tasks. This plan will be updated as we move throughout the next three weeks and time frames become more clear.
Additionally, every team member outlined about 5 specific tasks that we will be completing throughout the next cycle. Individual plans can be viewed here.
