Mechanical Engineering of Diagnostic Device Design

Our Process: Design, Fabricate, Analyze and Iterate

In general, the process and development of our mechanical engineering of diagnostic devices begin with design, then fabrication of parts and assemblies, analysis of their adherence to requirements, and, finally, iteration, resulting in incremental improvements. These processes are key to understanding Symbient’s Steps to Success. By utilizing our innovative mechanical engineering diagnostic device design services, we are able to perform the necessary diagnostic testing required to meet the appropriate standards.

We use SolidWorks® 3D CAD software along with Enterprise PDM for design control and secure CAD file management. We also utilize CAMWorks, a program that integrates with SolidWorks and enables us to seamlessly create error-free CNC machining tool paths.

By applying our creativity and considerable experience, we can design mechanical and fluidic assemblies that accomplish multi-step assays in just one or two user steps. This simplicity can enable your device to meet CLIA waiver or Point of Care requirements.

Our expertise in prototyping and DFM ensures that your design not only works in theory, but is optimized for manufacturing. DFM is one of our core capabilities and is critical to our specialization in high volume disposable products. Learn more about our Design for Manufacturing services and our Development Process.

As mechanical engineers, we have vast experience in developing devices with mechanical features ranging from the commonplace to the novel. Selected examples can be seen in our Case Studies.

A significant part of our design and engineering process requires analysis and testing of both rapid prototypes and injection molded devices, which we fabricate and assemble in-house.

Our product development services include specification of off the shelf components and primary materials such as plastics. There are thousands of types of plastics available, making our expertise in material selection a valuable part of our product development services. We help you select the right type, sub-type, grade, manufacturer and additives to meet the requirements of your device. Learn more about our Material Selection services.

Leverage our extensive experience and specialization in medical disposable products to efficiently determine whether a breakthrough design concept is feasible. We are experts at determining the best rapid prototyping method to use to ensure accurate results.

We offer FEA analysis using Solidworks Simulation. Simulation allows for linear static and time based dynamic analysis of our designs. Simulation allows us to quickly test and evaluate the design before spending time and money on prototyping. As a result we are able to achieve product requirements with fewer iterations.

If your device will incorporate electromechanical components, we invite you to contact us to learn more about our expertise at specifying, designing systems and integrating these components.

We can design your device to achieve specified heat transfer requirements, which are commonly specified to accommodate onboard heaters, thermo-chemical reactions or heat-generating electromechanical functions.

Our Engineering Lab

A significant part of our design and engineering process requires analysis and testing of both rapid prototypes and injection molded assemblies. Our expansive engineering lab contains a battery of test and measurement equipment that our engineers and technicians use to evaluate prototypes against product requirements. The results of this analysis informs any necessary design refinements, which can then be quickly executed in CAD, followed by fabrication of another prototype for further testing.

Advanced Testing Equipment

Notable test and measurement equipment include a digital force tester, microscopes, various gauges and transducers, leak testers, and advanced metrology equipment. The latter includes Keyence and Micro Vu systems. Our Keyence XM device allows product profile measurement with comparisons against 3D CAD data including measurement of freeform surfaces. The Keyence IM series measures larger targets on its 300 x 200 mm stage and captures up to 99 dimension in seconds.
