Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If conventional load connection designs are used with plastic housings, then the module structure is simple, but the space for additional components is limited
Solution Approach 1:
The load connection element extends vertically through the base plate and housing, utilizing the third dimension (height) to route connections. This allows additional components to be arranged horizontally in the interior space without interfering with load connections, effectively adding spatial freedom in another dimension.
Solution Approach 2:
The load connection element is nested within the housing structure, with its connecting section passing through the base plate and extending through the housing. This nested arrangement allows the connection element to occupy minimal space while still providing external access, creating room for additional components.
2Ease of operation
If load connection elements extend laterally through the housing, then external contact is achieved, but the module compactness is reduced
Solution Approach 1:
Instead of extending load connections laterally through the housing walls, the design routes the connecting section vertically through the base plate and up through the housing. This vertical routing in another dimension maintains external contact capability while preserving horizontal compactness.
3Strength
If the base plate is solid without recesses, then structural strength is maintained, but load connection elements cannot pass through
Solution Approach 1:
The base plate is segmented by introducing a recess that allows the load connection element to pass through. This segmentation creates a localized opening for electrical connection while maintaining the overall structural integrity of the base plate through strategic placement and dimensional design of the recess.

AI summary
A power electronics module having a base plate, a circuit carrier arranged on the base plate and a plurality of conductor tracks which are electrically insulated from the base plate. A power semiconductor component is arranged on one of the conductor tracks, and has a load connection element. In this case, the base plate has a substantially continuous first recess and the circuit carrier has a substantially continuous second recess, wherein the first and second recesses are arranged such that they are in alignment with one another. The load connection element has a first contact device which is in electrically conductive contact with a contact area of that side of the conductor track which is averted from the base plate, a second contact device for externally making contact with the circuit carrier, and a connecting section, which extends through the first and second recesses, between the first and second contact devices.
