Abstract

Road accidents frequently happen nowadays. The majority of the fatality accident involves motorcyclist and most of them encounter in head injuries. Lack of peripheral vision is one of the factors that affect the road accident or crashes. Although there are helmets with rear view mirrors that currently exist in the market provides good improvement on road accident, but limited usage of the helmet for motorcycle user due to the high price of the helmet. The price of the helmet are not affordable for poor motorcyclist. Thus, a low cost helmet with rear vision features made in sustainability element is proposed in this project. Market analysis is first carried out to gain the voice of target customer before the concept generated. Followed by numerous quality tools and strategic selecting tools like HOQ, AHP method, CES software, SolidWorks and others are used for giving a successful portfolio for further development of the product. HOQ method is adopted to determine the prioritized engineering target to be met by the new helmet; AHP method is used to select the best concept which generated via hand sketching; SolidWorks applied for 3D drawing and analysis of the new helmet. FEA analysis is applied to testing the workable and safety of the design. While Drop test analysis is used to analyze the impact of the rear-view helmet after collision happen. Furthermore, prototyping is carried out by using the FDM machine, Up Plus 3D printer for visualizing and testing purpose. Last but not least, the testing of the periscope concept in the rear-view mechanism is tested by laser pen. The prototype is worked as intended, i.e. the user can see the back view while using this periscope attachment device.
