Abstract
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.
