"Exploring Design for Manufacturing, Assembly, and Reliability in Product Redesign: Insights and Research Gaps"

Abstract

In order to remain competitive, the manufacturing sector must constantly introduce new goods to cater to changing
customer lifestyles. Redesigning an existing product with the goals of making it more reliable, cheaper, and more
satisfying for customers might lead to the creation of a brand-new product. One method of developing products and
processes simultaneously is known as Design for Manufacturing and Assembly (DFMA). This method prioritizes
reducing costs by taking manufacturing and assembly ease into account. In the early stages of design, product
dependability is just as important as manufacturability. Loss of market share and astronomical costs might result from
defective goods. The major goal of this research is to draw conclusions from existing literature and suggest avenues
for further investigation into product redesign using DFMA and DFR as an integrated framework. The goal is
achieved by conducting a literature review using bibliometric analysis, which is informed by the articles found in the
Scopus database. This study examines and discusses present and previous DFMA and DFR for product redesign,
leading to a systematic evaluation of the last five years. A DFMA-based product redesign paradigm that incorporates
reliability prediction into early product design is the subject of future study.
