IP67 Enclosure Design

One of the most challenging enclosure design projects is perhaps IP67 enclosure design for automotive electronics. These enclosures are subjected to unprecedented vibration, extreme temperature variations along with most unfavourable ingress and impact conditions.

The project team consisted mostly mechanical engineers supported by industrial designers. As usual, project incubation included study of existing products, learning the best practices in the industry and gearing up to set challenging goals for the project.

Styling inspiration was setup using the above image board by the industrial design team. This was followed by ideation sketches.Visualisation CAD was done to evaluate potential concepts.

These concepts were subjected to a selection process using Pugh matrix where the design criteria is weighed again concept features.

The design team worked in close co-operation with the client side engineers to make key refinements in the construction based on availability of hardware parts, ease of manufacturing and assembly.


Key changes were made and the design was moving towards its final revision.

Validation of the design was done by building the Mark1 prototype.Graphics & UI design.
Further, engineering refinement on Mark1 prototypes resulted in Mark2 prototypes which is now ready for mass production. Prior to mass production, prototypes new built for testing and compliance.
