Product Engineering & DfM
Once a preferred design is reached, the product can be engineered to ensure it will be fit for mass production and use. Parts become much more detailed and refined in this Design for Manufacture stage. Refined models can be analysed by Finite Element Analysis (FEA) software to verify strength under simulated loads, while systematic Failure Mode and Effects Analysis (FMEA) detects problems before the arise. Computer files and technical drawings are then shared with manufacturers for feedback to ensure a smooth transition to production.
For the Soundshield system, our team modelled all the plastics engineering details such as wall thickness, parting lines, support ribs, snap fits, fastener bosses and draft angles. PCB sizes and shapes were confirmed with the electronics engineer, and other internal components were modelled to ensure everything fit.
