Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If switching elements are rigidly connected to maintain stable conductive connection, then connection reliability is improved, but mobility and response to external force deteriorate
Solution Approach 1:
The switching arrangement is divided into multiple independent switching elements that can rotate relative to each other around a common axis. Each switching element maintains conductive contact with its neighbors through rotational movement rather than rigid connection, allowing the system to respond to external forces while maintaining electrical continuity.
Solution Approach 2:
The switching elements are designed to rotate dynamically around a common axis in response to external forces. This dynamic rotational capability allows the switching arrangement to adapt its configuration while maintaining conductive connections, resolving the contradiction between connection stability and responsiveness to force.
2Adaptability or versatility
If switching elements are arranged in complex spatial configurations, then adaptability to installation conditions is improved, but maintaining reliable conductive connection becomes difficult
Solution Approach 1:
All switching elements share a universal rotational mechanism around a common axis, allowing them to function reliably in various spatial configurations. This universal design enables the switching arrangement to adapt to different installation conditions while maintaining consistent conductive connection performance.
Solution Approach 2:
The switching elements are arranged to rotate around a common axis, utilizing rotational dimension to achieve spatial flexibility. This dimensional approach allows the switching arrangement to accommodate complex installation configurations while maintaining reliable electrical connections through the rotational mechanism.
3Reliability
If contact areas are designed for high contact force, then conductive connection reliability is improved, but temperature independence and mobility deteriorate
Solution Approach 1:
The contact areas are designed to maintain conductive connection through rotational movement rather than high static contact force. This dynamic approach reduces thermal stress and improves temperature independence while maintaining connection reliability across varying thermal conditions.

AI summary
A switching arrangement comprises a series of switching elements (2) which are conductively connected to one another at contact points in their rest position and of which at least two switching elements can be moved from their rest position and the conductive connection under the influence of an external force. The switching elements (2) consist of a non-conductive base body and are coupled to one another by means of convex coupling sections (6, 66) which are each freely rotatable in a concave recess (8). The base body is provided with a conductive contact area (22, 26) at each coupling section, the two conductive contact areas of a base body being in conductive connection with each other. Under the influence of an external force, a contact section is rotated, causing its conductive contact area to move away from the adjacent conductive contact area and thus breaking the conductive connection.
