Problem Definition Documents
All documents related to the problem definition phase are located here.
Team Vision for Problem Definition PhaseThe team plans to define the problem and meet the deliverables presented in the problem definition.
The team has defined the problem definition and has met with the customer to go over customer requirements. From those requirements, and from the PRP, the team has defined engineering requirements. The use cases and risks were identified. benchmarking was also completed. The team has also assumed roles, such as engineering leads, project managers, communications leads and quality control and purchasing. The team has also defined its values.
Project SummaryChildren with Down Syndrome typically learn to walk about year later than other children. A treadmill can be used to help these children learn to walk earlier. The child’s parent will support their body weight on the treadmill and gradually add more of their weight as they learn to walk. The treadmill will be used 5-8 minutes daily at home necessitating the need for portability and easy storage.
The goal of this project is to provide a functional prototype that is easy to use independently, cost effective, long lasting, safe for both the parent and child, and provides time, speed, and supported weight as feedback. The current commercial designs are heavier and larger than desired. Design, testing, and supply chain documentation with alternative designs will also be provided, as well as a user guide.

Plans for next phase
- The team plans to have completed functional decompositions. We will have reviewed and compared other portable treadmills on the market. We will have selected a generated some concepts and selected one. We will design the systems architecture and completed engineering analysis.
