Lower 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 Testing

Conduct 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.
