Team Vision for Build & Test Prep Phase

This phase looked to reassess where we as a team left off in the project at the end of last semester. During this quick phase we planned our schedule for this phase and for the systems build and test phase. We were able to send in our request for the manufacturing of the seat plate down in the machine shop, and we are going to able to resume welding the support structures since the labs reopened at the start of the semester. Additionally, Kaylie has begin to work on finding and gathering materials to complete the bacteria adhesions and sanitation testing of the chosen materials and coatings.

Additionally, the team has begun to shift our focus to the testing of the hydraulic system and getting that system up and running. We implemented some of the changes we had discussed before in the previous design reviews, that would prevent the hydraulics from getting stuck and began to manufacture the parts needed to fix the other hydraulic. We will continue machining of the hydraulic into the next phase, and will begin the testing of the redesign. 

Test Plan Summary

All of the test plans needed to validate that the engineering and customer requirements are being met were completed during last phase. These test plans will be executed during later phases once the machining/assembling of the device is complete. The materials that are needed to conduct testing are available or will be purchased towards the beginning of the next phase, in order to immediately start testing once the build is complete. 

The completed test plans are linked here. 

Additionally, the team decided that to get input on what customers would want from a design standpoint, Kaylie and Kimberly were start working on a survey of sorts that the team will send out, in order to determine the best design that fit the needs of the stakeholders of the device. We specifically want input about the armrests and lever for the lifting feature, shape and size. 

Risk and Problem Tracking

Over break, the risk document was updated and the risks that are no longer an issue were closed out and the risks that were still standing were reevaluated and the level of likelihood and severity. The link to the updated document can be found here. 

The problem tracking document was also updated at the end of last phase and that can be found here.

Plans for next phase

Going into the next phase, the teams looks to finish building the device structure and the hydraulic system and begin completing the testing required at a subsystem level. Once that is complete the team is looking to combine and integrate both components and begin testing at the system level. Additionally, during this time the team will work in depth with Kimberly in order to ensure a appealing and comfortable design of the device. Before we get to that point, specifically during next phase the hydraulic pistons will need to finish being machined and the hydraulics need to be assembled. Furthermore the waterjet should be up and running within the next two weeks (estimated), so the other device structure should be able to be assembled. In the meantime, Kaylie will begin to conduct the biomaterial testing, and will be working on a design survey for some of the other device components like the armrests and the lever.
