Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contacting device uses a complex structure with multiple separate components for contact elements and housing, then it may provide adequate electrical connection, but it becomes difficult to assemble and increases manufacturing complexity
Solution Approach 1:
The patent combines the housing and first contact element into a single integrated component. The housing is formed as one piece with the first contact element, eliminating the need for separate assembly of these parts. This merging reduces the number of components and assembly steps while maintaining the electrical connection reliability through the integrated design that ensures proper positioning and contact.
2Ease of manufacture
If contact elements are made as separate displaceable components, then assembly may be simplified, but electrical resistance increases due to additional contact interfaces
Solution Approach 1:
The housing and first contact element are merged into a single component, eliminating the contact interface between separate parts. This reduces the number of contact points and potential sources of electrical resistance. The integrated design ensures direct electrical pathways without additional joints or interfaces that could increase resistance.
3Adaptability or versatility
If multiple separate components are used in the contacting device, then flexibility and adaptability may be improved, but the number of components increases making the device more complex and expensive to produce
Solution Approach 1:
The housing and first contact element are combined into a single integrated component, reducing the total component count. This simplification lowers manufacturing costs and assembly complexity while the design maintains adaptability through the spring element mechanism that allows for adjustable contact pressure and the ability to accommodate variations in circuit board positioning.
Solution Approach 2:
The spring element provides dynamic adjustment capability within the integrated housing-contact element structure. The spring allows the contact element to move and adjust its position and contact force, providing flexibility and adaptability without requiring multiple separate components. This dynamic mechanism compensates for tolerances and variations while maintaining reliable electrical connection.

AI summary
A contacting device has a housing in which a first contact element is arranged. The first contact element has a receiving chamber for a second contact element, which is open with respect to at least one opening of the housing. The first contact element is displaceable relative to the housing in a direction transverse to a central longitudinal axis of the receiving chamber against a spring element, so that the second contact element is insertable into the receiving chamber and capable of being clamped in the receiving chamber by the spring element. The first contact element is firmly connected to at least one plug-in contact element. By this device, a transmission of electrical energy from a power supply line to a circuit board can be achieved in simple and reliable manner.
