Problems We Faced Separation between pipes Stoppers We had to ensure that the legs were stable and that no "wobble" effect was produced. We solved this by limiting the extension of the telescopic pieces. Our design needed to adjust to different sizes of treadmills so we decided to specify that U.P.A.L.S is designed to adjust to treadmills sold at Canadian Tire.
Recommendations This product has a maximum load of 40 lbs. This will not completely fix a person’s poor posture or back pain; it is a tool that may help improve posture while spending many hours in front of a computer screen. Arms should be placed parallel with elbows kept straight.
If We Were To Move Forward Design Improvements (type of materials, hinges as opposed to welded area to increase portability) Different sized models Accessories (coffee holder, side extensions) Apply for patents Choose a manufacturer Market production
