Abstract—The lower limb exoskeleton (LLE) is a device used to assist paraplegics in regaining their ability to walk. The LLE is capable of providing paraplegics with a better degree of locomotion than a wheelchair. However, in LLE design, size is a critical issue that needs to be considered. The LLE should be small in package, compact, and portable. Therefore, this study presents a strategy to solve the issue with dimensions in LLE design to match the Malaysian anthropometric characteristics. The TRIZ (Russian acronym for “Teoriya Resheniya Izobreatatelskikh Zadatch”) inventive principle method is used to generate the ideas discussed in this study. As a result, adjustable LLE designs that match the Malaysian anthropometric characteristics were developed, where the critical dimensions for LLE were obtained from previous anthropometric research in Malaysia.
