The proposed product uses a new type of force-measuring platform with high reliability as a developmental core of the technology to design a method for evaluating the weight distribution and the center of gravity of the manual wheelchair as a calibration system.The promotion of the clinical application of the detection platform for subsequent wheel axle balance and weight distribution will enable the design of the wheelchair to have superior mobile handling, safety and stability.

The force plate was usually equipped with three-dimensional load cell to measure the force in the three directions to estimate the ground reaction force and calculate the position of the pressure center. The cost is relatively high, thus it can be barrier to widely promote in clinical applications.

This can also provide more efficient mechanical performance, and better safety and stability for the users. Apart from the reducing purchasing threshold, this design can also provide easier and lower cost of after-sales maintenance service for the wheelchair users. These benefits expand the commercial application value of this commercial calibration system.
