Design Efficiency Analysis Towards Product Improvement Using DFMA

DFMA is a methodology which is used to select the optimum design in the early stages of product design. This paper deals with the modeling of pedestal fan using DFMA method. Method used for DFMA analysis is Boothroyd Dewhurst method. The aim of study is to analyse the existing design of pedestal fan and to identify the pockets of improvement and suggest the new design of pedestal fan with improved design efficiency. DFMA is a concurrent engineering tool that is used to improve the design of the product which leads to minimization of the production cost. It also shortens the product development time by reducing the number of components, increases the quality of the product as well as reduces the overall product cost by reducing the assembly cost as well as manufacturing cost. Part modelling of each component of existing design as well as improved design of pedestal fan was done with the help of design software. Increase in the design efficiency shows the easy assembly process i.e. less time taken during assembly operation of new design in comparison to the existing design.
