Most existing products are designed without consideration of one-handed
users. This includes the equipment and tools normally used in motorcycle
workshops. A majority of these products demand a two-handed user by
default and unintentionally deny access to one-handed users. Thus,
this project aims to design and fabricate a prototype of a motorcycle tire
dismounting tool intended for one-handed users. The project starts with a
preliminary study, a preliminary concepts evaluation, concepts generation,
concept selection and concept refinement. Methods such as observation,
brainstorming and the weighted objective method were employed in the
course of the design process. Solid modeling software, CATIA V5 was used
to produce a 3D drawing of the concept designs and the final design of the
motorcycle tire dismounting tool. Finally, the prototype of the tool was
built and tested. The tire dismounting process is possible to carry out with
one hand using this product. Users just need to push or pull the handle of
the product with a 29 N forc
