Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex spring system with Belleville springs is used to clamp the semiconductor element, then reliable electrical connection is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces expensive, complex Belleville springs with a simple, inexpensive spring washer that can be easily manufactured and replaced. The spring washer serves the same clamping function but with significantly reduced complexity and cost, aligning with the principle of using cheap, simple components to achieve the desired function without unnecessary complexity.
Solution Approach 2:
The patent extracts the essential function of the spring system (providing clamping force) from its complex implementation (Belleville springs with multiple components) and implements it with a single, simple spring washer. This separates the core function from the complex structure, achieving reliability through functional simplicity rather than mechanical complexity.
2Force
If multiple tension screws are used to mount the semiconductor element, then clamping force is achieved, but mounting time and risk of tilting increase
Solution Approach 1:
The patent merges the functions of multiple tension screws into a single spring washer that provides uniform clamping force around the semiconductor element. This consolidation reduces the number of mounting operations from multiple screw tightenings to a single spring washer installation, significantly reducing mounting time while eliminating the risk of tilting associated with uneven screw tightening.
Solution Approach 2:
The spring washer automatically provides the necessary clamping force through its elastic deformation, eliminating the need for manual adjustment and tightening operations. The component self-regulates the clamping force, reducing mounting time and ensuring uniform pressure distribution without requiring precise manual intervention.
3Device complexity
If a non-modular design with direct mounting on base plate is used, then structural simplicity is achieved, but adaptability and semi-fabrication capability are reduced
Solution Approach 1:
The patent segments the mounting system into a removable spring washer component that can be independently manufactured and assembled. This segmentation enables modular construction where the spring washer acts as a separate, replaceable element, allowing for semi-fabrication and easy adaptation to different configurations while maintaining structural simplicity.
Solution Approach 2:
The spring washer serves multiple functions: providing clamping force, ensuring electrical contact, and enabling modular assembly. This multi-functionality allows the same simple component to support both structural simplicity and modular design capabilities, achieving adaptability without increasing complexity.

AI summary
The invention relates to a semi-fabricated switching device comprising a semiconductor element (1) and a housing (2) comprising a spring system with a ring-shaped washer (6) laterally surrounding the semiconductor element (1) for clamping the semiconductor element (1) between two pole pieces (3, 4). The washer (6) is deflectable between the pole pieces by a first deflection element (7), which contacts the washer (6) in a first contact area (61) on a first side (60), and by a second deflection element (8), which contacts the washer (6) in a second contact area (63) on a second side (62). The first contact area (61) is displaced to the second contact area (63). The first and second deflection element (7, 8) can deflect the washer (6) such that in clamped condition an electrical contact is achievable between the pole pieces and the semiconductor element (1).
