        Product Development

        Detailed Engineering and Analysis

        The ultimate success of a product is the result of “dotting the i’s and crossing the t’s”.  This means designing the product to use appropriate materials, be easy to manufacture, meet the customer’s performance needs and be cost effective.  Satisfying each of these needs requires the attention to detail at which Stress Engineering Services (SES) excels.  Our detailed engineering and analysis activities involve evaluating the performance of the product over the full range of variability caused by component dimensions, materials, assembly, and usage.  We employ classical engineering tools, laboratory experiments and advanced computer-based analysis techniques.  The objective of this work is to develop the data needed to support the product function and life targets.

        Stress Engineering Services is recognized as a leader in the application of engineering analysis techniques to solve challenging development problems.  At SES, we are experts in the use of Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), heat transfer calculations, and vibration analysis to evaluate product design with a “virtual prototyping” approach.  We have a track record of success with having the first parts out of the manufacturing process satisfy all of the functional needs of the product.

        Design is just one element of successful product development.  The materials, manufacturing systems, cost, packaging and distribution must also be considered and optimized in order to provide a winning product.  Our tightly integrated engineering and laboratory services provide key results for successful product development.

        Materials – the SES laboratory is equipped to characterize the performance of many materials in order to provide data needed for product design and life assessment.  Our capabilities include determining temperature and time dependence, effects of sterilization, aging/life assessment, manufacturing compatibility and cost.

        Functional Performance – SES evaluates input and output forces (such as squeeze to dispense or removal torque), determines deformation of products during use and collects quantitative data on the forces acting on individual components of a device.

        Analysis – Employing FEA, CFD, thermal and vibration analysis tools, SES identifies critical stress points, flow stability and pressure drops, thermal hot spots or heat dissipation points, and component performance in a dynamic environment.  We deal with complex behaviors like high-speed impact events, extreme temperatures, long life requirements and high loading.

        Risk Assessment – Adequately assessing risk, including performance, manufacturing, and safety, is critical to product success.  SES is highly experienced in applying risk assessment methods to characterize new and existing products.  Our toolbox includes Fault Tree Analysis (FTA), Failure Modes and Effects Analysis (FMEA), Hazard Analysis (HA) and identification of critical components, among others.
