Design optimization of strain pad for a medical product

The Client:

A Leading medical testing service providers from Canada


To optimize the design of the silicon pad subjected to longitudinal loading conditions using FEA Analysis. The objective for optimization was to achieve uniform strain distribution across all compartments. FEA Analysis was used to achieve uniform strain distribution.

Client Expectations:

Client expected us to simulate and predict the strain distribution for different pad designs and suggest design modification to achieve a design that has uniform strain distribution. Client also expected us to use appropriate FEA methodology in order to achieve uniform strain distribution.

FEA Analysis Project Challenges:

The FEA Analysis project required to model nonlinear silicon rubber. Achieving convergence was one of the biggest challenges for our engineers. We have FEA experts with experience of working with nonlinear materials. Our FEA experts selected appropriate FEA methods, options and meshing in order to achieve the best quality FEA analysis results for our client.

FEA Analysis Project Deliverables:




FEA Analysis of medical testing device


FEA Analysis Project Benefits:

The project saved the client overall ofapproximately 80000USD which includes the manpower and Testing resources required. In addition to cost, the project also introduced the client to FEA Analysis methodology which they have started utilizing to develop their different range of products faster.

FEA Analysis Project Hours:

  • FEA Analysis Model Preparation: 12 Hours
  • FEA Analysis Solving Time: 5 Hours
  • FEA Analysis Results Discussion: 3 Hours
  • FEA report preparation: 2 Hours

FEA Analysis Project Duration:

  • 3 days

FEA Analysis Project Team:

  • FEA Analyst
  • FEA Consultant
  • FEA Analysis Lead

Customer Delight Experience:

The client expected us to complete the FEA Analysis project within 10 working days which we delivered in 3 working days. Our FEA experts examined the project both from domain and FEA Analysis aspects. Our FEA analyst had referred a lot of literature for related to the testing for medical industry and incorporated the learning’s into the FEA Analysis report. Our FEA Consultant conducted a critical assessment of the FEA Analysis report and provided his feedback to include as recommendation for design to the client. The methodical approach to conduct the FEA Analysis was very much appreciated by the client.

Medical Devices Market Insights:

The increased investments into R&D by many giants into medical devices segment is evident that rapid growth is expected in the coming years in this sector. With increased R&D efforts, there will be new product development and with increase product development there is more need for testing. FEA Analysis will be very much helpful to evaluate the product concepts even before having their prototypes. Off course FEA Analysis is never an alternative for Testing but it can easily provide an early assessment for the products.
