Abstract

Spinal Board is one of the first aid evacuation equipment used in emergency medical service acts with the purpose to sustaining life of the accident victim before finally getting further treatment from medical personnel. However, problems with ineffectiveness, inefficiency and discomfort of existing spinal board on the market are frequently found. This study demonstrates the applicability of integrated methodology in determining the design requirement for an ergonomic spinal board. The methodology was derived from multidisciplinary approaches consist of quality function deployment (QFD), Kano model, theory of inventive problem-solving (TRIZ), and failure mode effect analysis (FMEA). The Kano model was used to investigate the customer satisfaction needs (CSNs). Then, the CSNs was processed using QFD method in the House of Quality (HoQ) matrix to identify the critical ergonomic design areas and the key problems in implementing the design. The TRIZ method solves the problems in order to provide solutions for innovative product design. It provides the design team with a methodical way of finding the causes and effects of failures before the design is finalized. In performing an FMEA, the product and/or production system is examined for all the ways in which failure could possibly occur. This study has generated a design requirement for ergonomic spinal board which is able to accommodate customer’s expectations and needs. Thus the integrated methodology has indicated promising empirical findings in determining design requirement for ergonomic product with more concrete evidence.
