Assistive device design for animal needs in human society

Abstract

This paper introduces the design and development of a new assistive wheeled product for handicapped dogs. The device is specifically targeted for a 5-year-old mastiff who lost one of his front legs due to a gunshot accident in California, U.S. This study involves research, design, and usability testing with a series of working prototypes on the dog. The significant challenges in collecting accurate data from the testing and process of the new product development will be illustrated through demonstrating the mobility, durability, safety, stability and comfortability of the device. After the efforts of diverse approaches and different product directions, a wheeled assistive device, similar to dog wheelchairs, has been invented by the industrial design team from The Design School at Arizona State University in the U.S.
