Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermally insulating connection devices are used to connect electronic components to housing parts, then thermal insulation is improved, but mechanical connection stability may be compromised
Solution Approach 1:
The connection device is segmented into multiple independent fastening elements (first fastening device for carrier, second fastening device for housing part) that are thermally isolated from each other. This segmentation allows each fastening element to independently provide mechanical stability without creating thermal conduction paths between the carrier and housing part.
Solution Approach 2:
The connection device acts as an intermediary element between the carrier and housing part, providing both mechanical fastening functions while preventing direct thermal contact. The thermally insulating material used in the connection device body isolates the two metallic fastening elements, allowing it to mediate the connection while blocking heat transfer.
2Strength
If metallic fastening devices are used for stable mechanical connection, then connection strength is improved, but thermal conduction increases
Solution Approach 1:
The metallic fastening devices are segmented into separate first and second fastening elements that are spatially separated and thermally isolated. Each metallic fastening element provides strong mechanical connection to its respective component (carrier or housing part) without creating a continuous thermal path, as they are isolated by the thermally insulating connection device body.
Solution Approach 2:
The connection device exhibits local quality by having metallic fastening elements only where mechanical strength is needed (at the carrier and housing part interfaces), while the body of the connection device is made of thermally insulating material. This localized use of metallic material provides connection strength exactly where required without creating unwanted thermal conduction paths.
