Casing technology

Economically optimised casings that meet the highest requirements

Innovative systems and devices must meet the highest requirements in terms of quality, reliability and handling. This, however, often leads to very cost-intensive designs caused by late or incorrect decisions taken during product development.

The quest for suitable materials and manufacturing technologies starts at the beginning of every casing design. Especially in casing technology, subsequent modifications frequently result in higher costs. WILD has developed a methodical approach to avoid this and to determine the ideal combination of technology, design and cost structure from the very start. It involves a systematic decision process that helps customers meet both technical and normative, as well as economic requirements. This balancing act is based on mathematical optimisation techniques which search for the best combination of material and manufacturing technology using characteristic indicators. Priority must be given to the most objective assessment of the various options available since this is the only way to develop an efficient and innovative device concept.

 

Software-based decision-making

More specifically, a process developed by WILD takes the development team through a systematic decision-making
procedure which results in the selection of the ideal material for the intended function in combination with the manufacturing technology best suited for the production volume. It can therefore be said that, where manufacturing technologies are concerned, mathematical optimisation is also used to determine the most cost-effective solution. In addition, this delivers an outlook on the expected cost structure, which includes the initial costs for tools and equipment and the costs for material. This structured method ensures that WILD always opts for the most cost-effective manufacturing process for the development of a product. It also makes it easier to identify how much planned the design features will cost in the production of the casing. This, in turn, gives customers the certainty of having taken the best decision for their product since it also assesses the monetary impact of aesthetic features.

An impressive example for the application of this optimisation method is the biochemistry analyser, a completely novel
all-in-one device for in-vitro diagnostics. In this compact tabletop device, it was possible to separate the user and process areas, making operation both easier and safer. This, however, meant enormous challenges for the casing technology. On the one hand, the aim was to develop a cost-efficient casing while, on the other, to meet the highest aesthetic requirements with a high-contrast design. By applying the systematic decision process, the developers at WILD managed to choose casing components with an ideal cost-benefit ratio. As a result, the customer obtained the necessary investment and planning certainty to quickly introduce the biochemistry analyser on to the market with a perfect look and feel.
