Prototypes make concepts tangible

Design models permit assessment of exterior form, capacity, proportions, surfaces and colours. For instance, they might come as models with uncoated surfaces, cut into shape using modelling foam or wood, used to assess capacity or proportions, or finished models for brochure or catalogue photos that are virtually indistinguishable from the finished series product.

Functional models are used to assess a certain operating principle or engineering idea. It is not always necessary for their form to be identical to the finished product. They could be mere mechanical models or models containing electronic components.

Ergonomic models are the interface between human beings and the product. They are used to check all relevant movement sequences and whether, for instance, wheelchair users can also operate the product or whether the input and output elements are positioned sensibly. The dimensions of handles, grips or switches can also be tested.

Prototypes are made from components largely identical to their series counterparts and possess all the properties of the future product. All technical components are installed, and the surfaces and colours are also identical to the series version, enabling a detailed assessment of the product as a whole. The final touches to series production can be added, based on the prototype.
