Feasibility Assessment and Preliminary Design
Many product development activities end up over budget and missing schedule deadlines as a result of spending significant effort on concepts that have little chance of success. At Stress Engineering Services (SES), we specialize in quickly evaluating and narrowing down the many concepts that generally come out of the ideation phase of product development to focus on the few that have the best chance of satisfying the performance requirements. Our ability to rapidly complete the feasibility assessment provides great benefit in the product development process by allowing the (generally limited) resources available to focus on ideas that can be made to work.
The feasibility assessment typically includes basic engineering calculations to understand functional performance, preliminary sizing of key features and identification of material candidates. The concepts are also evaluated using cost modeling for various materials and manufacturing techniques. Ultimately, the feasibility assessment creates a ranking based on each concept’s effectiveness at meeting the requirements, the development risk and time, as well as the cost.
The primary objective of Stress Engineering Service’s preliminary design effort is to identify the critical technical hurdles associated with a concept and determine how to overcome these hurdles. SES specializes in developing reliable solutions that permit the development process to proceed at a fast pace. This includes making an early selection of candidate materials as well as the manufacturing methods required to produce components of the product.
The preliminary design work frequently involves basic engineering calculations using closed-form models, finite element analysis (FEA), computational fluid dynamics (CFD) and thermal models. The calculations are often supplemented by proof-of-concept tests and experimental data related to function, human factors, ethnography and overall product usability. Product reliability is integrated into all aspects of the design process.
