What does Design for Assembly (DFA) primarily focus on?

Design for Assembly (DFA) primarily focuses on reducing the number of parts and simplifying assembly. The core principle of DFA is to minimize the complexity of the product assembly process, which can lead to lower production costs and improved efficiency. By reducing the number of parts, manufacturers can streamline the assembly process, making it quicker and less prone to error. Simplifying the design not only enhances manufacturability but also contributes to better overall quality and maintainability of the product, ultimately benefiting both the producer and the end user.

In this context, the emphasis on fewer parts can also lead to reduced material costs and lower inventory requirements, as there are fewer components to manage. This is particularly important in high-volume production where even small efficiencies can lead to significant cost savings.
