A fundamental step before starting product design will be identifying user requirements, so that it becomes clear what is expected for the final product. For product design, users who have contact with the device, such as patients, doctors or service technicians, are particularly important. Once we have defined what users expect from the device, we will brainstorm various concepts in presenting hand sketches, which provide an initial idea of the design, user elements and functionality. In this process, we emphasize not only to deliver innovative designs, but also to consider the manufacturability and to maximize the usability, which has to be checked later in the course of the usability evaluation anyway.

We provide ideas, hand sketches and 3D models to discuss how concepts could be realized, keeping  feasibility in focus.

After a concept has been chosen we continue with the detailed CAD design of the system’s mechanical components. To avoid subsequent iterations, it is advantageous to already know the inner workings of the medical device, such as printed circuit boards or other electronic components, parts or assemblies. Missing CAD data can be measured and remodeled in the course of reverse engineering. Already during the modeling of the outer skin, the design surfaces, we attach great importance to a parameterized model. In this way, adjustments to the geometry of the finished design, such as in the case of subsequent changes to components, can be carried out with minimal effort.

We deliver fully parameterized, production-ready design surfaces and solid modeling of housing parts.

If reverse engineering is needed, we also do CAD reconstruction based on point clouds generated by 3D scans in NURBS surfaces. Missing CAD data of existing components can be reconstructed by means of measurement and fed into the assembly model.
