Team Vision for Detailed Design Phase

Our plans for this phase included:

What we actually accomplished:

In this phase, we accomplished most of the above tasks. Finalized the design of all components except for the grab bars. This will be one of our first action items at the beginning of MSD II. We purchased items for lifting and seat components, but not for the grab bars. Once the grab bar design is finalized, these materials will be ordered.

Updated Charts

Due to the addition of new concept ideas in the last couple phases, out team decided to make some updates to our engineering requirements and risk assessment.

Risk Assessment

Below is a section of our updated risk assessment. Our team has included a sliding track for out arm rests, which poses new hazards, which are outlined in the chart. Our complete updated risk assessment is attached.
