MSD IIMSD II Test Review
RecommendationsLower the overall weight of the device
Use different materials. The legs could still be 304 stainless steel but the top and bottom base could have be a anodized aluminum or thinner 304 steel to cut back on weight and price.
Different position of the actuator. Instead of having the actuator push on a rod have the actuator attach to the back of the seat pushing vertically up or down to raise the client.
Obtain appropriate actuator
Be consistent with stakeholders and requirements
Manufacture parts earlier
Order parts earlier
Logistics was major role in producing the bath tub lift.
Parts that came late delayed the development of the device.
Wood demo rather than PVC demo
After testing the demo with a team member springs are needed to help with the initial movement of lifting the user. Apply 50lbs springs on the breaks or have higher breaks which would increase the lowest height of the device.
Have the seat able to slide left and right or at a 45 degree angle instead of forward and backward. The seat does not come out far enough for the client to sit on the device comfortably.
Future TestingConduct human testing by having team member sit on chair and have the device go up and down
Test device all together in water and in the tub.
Test seating position in the tub and the user movement to get on the device and off.
