Integration of TRIZ, morphological chart and ANP method for development of FRP composite portable fire extinguisher

This manuscript explains the conceptual design of carbon fibre reinforced polymer composites portable fire extinguisher. In this project, the integration of theory of inventive problem solving (TRIZ), morphological chart and analytic network process (ANP) methods was applied to produce the concept designs. The current design of fire extinguisher possesses great difficulties to many users due to its weight and design. In this study, a new design was developed to replace the existing heavy and bulky fire extinguisher design. A preliminary steps were used in the design planning to construct a proper direction to create a new design product. Afterwards, the detailing of the engineering parameters was refined using the TRIZ contradiction matrix to provide inventive solutions for the product. The finalised inventive solution from TRIZ is later incorporated with the morphological chart along with ANP technique to systematically develop the final conceptual design of portable fire extinguisher. The results showed that Concept Design 1 scored the highest value and ranked first among the four designs proposed. Finally, challenges of the portable fire extinguisher design and the improving criteria in concurrent engineering were presented.
