Abstract

Shield has been used as a reliable defence for infantrymen and knights since centuries. Great evolution of armours went on and this led to progressive development and improvement on the design of shield, for example the various shields used by law enforcements today. However, a flexible shield for firefighting purpose is yet to be designed and developed. The suitability of interaction between the shield and user also remained questionable. Thus, the objective of this research is to propose a conceptual design of a shield for firefighting purpose, considering the ergonomics factors of the shield. The methodology used are customer survey to define fire fighters’ needs, House of Quality (HoQ) in quantifying customers’ needs, morphological chart in defining concepts, Pugh selection method for selection of the best design, RULA analysis in measuring ergonomics score, and lastly Finite Element Analysis (FEA) in simulating the behaviour of shield under thermal and load exertion. Scutum-shaped shield has been selected as conceptual design, with aluminium alloy 6061-T6 as the inner body material of shield, and is wrapped by the standard elastic modulus type (HT) carbon fiber. The shield design has achieved a final score of 3 in RULA analysis for both standing and kneeing position, which indicated the shield possess only low risk of Musculoskeletal Disorder (MSD). Besides, the results of FEA have proven the mechanical properties of both the materials used in shield design to be consistent with the findings of literature review.
