Design For Assembly
Design for Assembly is a methodology for evaluating part designs and the overall design of an assembly. It is a quantifiable way to identify unnecessary parts in an assembly and to determine assembly times and costs. Using DFA software, product engineers assess the cost contribution of each part and then simplify the product concept through part reduction strategies. These strategies involve incorporating as many features into one part as is economically feasible. The outcome of a DFA-based design is a more elegant product with fewer parts that is both functionally efficient and easy to assemble. The larger benefits of a DFA-based design are reduced part costs, improved quality and reliability, and shorter development cycles.
Benefits of using Design for Assembly software
Product engineers know that 85 percent of manufacturing costs are determined in the early stages of design. When you make informed design decisions during the concept stage, you avoid costly corrections later on. Use DFA software to
Estimate difficulty of assembly.
Support decision making.
Benchmark existing products.
Add focus to design reviews.
Sharpen design skills.
Integrate design and manufacturing.
The Link to Design for Manufacture
DFA complements Design for Manufacture (DFM). Engineers use DFA software to reduce the
assembly cost of a product by consolidating parts into elegant and multifunctional designs.
DFM software then allows the design engineer quickly to judge the cost of producing the new
design and to compare it with the cost of producing the original assembly. Used together,
DFM and DFA software gives engineers an early cost profile of product designs, providing a
basis for planning and decision making. Such analyses, when performed at the earliest stages
of concept design, have the potential to greatly influence manufacturing and other
life-cycle costs before the costs are locked in.

“DFMA is a fundamental business process for the Dell engineering team because it supports our holistic approach to cost. It helps us analyze our designs and make decisions that lower overall costs, not just product costs.”
“Increased manufacturing throughput, reduced damage rates, higher quality, streamlined logistics, and faster delivery are all outcomes of weaving DFMA into the development cycle.”
