Manufacturing Integrated Algorithm-Based Product Design – Case Study of a Snap-Fit Fastening

Integrated product design in manufacturing aims to comprehensively tap manufacturing potential for higher durability, lightweight design and additional functional benefits in the realized product. This paper introduces an approach for systematically integrating manufacturing induced properties into product design and is illustrated with a case study of an innovative snap-fit fastening integrated into a linear flow split profile structure. After analyzing and comprehensively considering manufacturing processes as well as assembly and use processes, product properties are transformed into a formalized design task. Optimal product design is provided by algorithm-based solution finding methods that specifically consider the manufacturing induced properties. This allows the optimized snap-fit to systematically utilize manufacturing technologies to combine a simple assembly and high holding forces.
