Ergonomic inclusive designof innovative toiletfor disable user

ABSTRACT

Currently, the existing toilet design sold in the market has not satisfied criteria of the disabled people. Disabled includes the physical impairment, the hearing impairment, the visual impairment, and the cognitive impairment. This people prefer use a specific toilet to the public toilet. However, a specific toilet was not available in any place. This condition becomes a problem for them. As for the existing public toilet does not provide easiness in use and even has potential risk to lead accidents for them. The toilet was designed to serves only the normal people. Therefore, it needs to design a public toilet which can be used universally. So normal and disable people can use it easily and conveniently. Objective of this research are to develop design parameters of toilet based on the inclusive design concept to satisfy customer criteria. Axiomatic design was implemented in this study to identify the design parameters by means of mapping process from customer attributes and functional requirements. Anthropometric data was used and non paramethric statistical analysis was conducted to validate the proposed design. Result of this study showed thatdesign parameters identified was valid to satisfy customer criteria at 5% of significant level. The design parameters encompassed material used, dimensions and position of toilet attributes as well as additional environmental appliances.
