AB  - Devices such as walkers can sometimes cause secondary injuries to patients if not used properly.
Although, there are existing redesigned walkers which prevent falls from happening, it appears that there is still
room for improvement towards developing a more innovative and ergonomic walker. Hence, this study aims to
design and develop an innovative walker for improved usability using ARIZ. ARIZ which is an algorithm for
inventive problem solving is widely used for complex problem solving with minimal changes to the system. The
ARIZ approach in this study proposed three inventive principles to be used namely dynamicity, asymmetry
and nested doll. The solution involved a double slider crank mechanism which enabled the newly designed
walker to effectively support gait movement and stair-climbing. Overall, researchers of this study successfully
designed and developed a unique and innovative ergonomic walker for the elderly and disabled people with
intentions to prevent further injuries or accidents.
