Integration of Triz, morphological chart, and pugh matrix for redesigning ergonomics of car interior for the mobility-impaired

Individuals with disabilities in Malaysia are among the most vulnerable of the minority group in the Malaysian population. According to the World Health Organization (WHO), 15% of the world’s populations has some form of disability. According to Jabatan Kebajikan Masyarakat Malaysia (JKM), the nu...

According to the World Health Organization (WHO), 15% of the world’s populations has some form of disability. According to Jabatan Kebajikan Masyarakat Malaysia (JKM), the number of registered disabled people is increasing, as recorded by their annual statistics.

The objective of this research is to redesign an ergonomics interior of a car for the mobility-impaired using the Theory of Inventive Problem Solving (TRIZ), specifically function analysis, cause and effect analysis, and contradiction matrix. This redesign focuses on the driver’s area of a compact car drove by upper limb disabled drivers, lower limb disabled drivers, or combined limb disabled drivers.
