Final product

Here are some pictures of the final product:

Final prototype: internal structure update

In the initial sketches of the final prototype, the internal frame consisted of a lot of parts and different materials: wooden strips, aluminium strip, steel band, screws. To simplify the product, these parts were replaced by one piece of wood.

Final prototype: drawing + dimensions

The images below show the dimensions of the scale and a top view. The hinges are big because this indicates the function of the hinges. In the drawing there is a small (green) color accent. To match the color with the personal taste of Henk, we asked him his color of choice. The colors that Henk prefers for the hinges are dark orange or black.

Idea: Rope

This idea consists of a rope and a balance on the upper part of the rope. The idea is that Henk can climb the rope and see his weight. The advantage is that the system is very compact. This idea is not possible for Henk because of two reasons:


- The muscles under his waste are not enough developed to support the weight of his legs. This could injure the muscles.


- It's very difficult to 'land' back in the wheelchair. When the rope is above the wheelchair, Henk would land with his feet in the chair. When the rope is in front of the wheelchair, Henk would land in front of the wheelchair.
