Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electron beam treatment is applied to enhance conductivity of lamella spring surfaces, then electrical conductivity is improved, but spring properties are adversely affected
Solution Approach 1:
The invention divides the lamella spring contact into two separate components: the lamella spring contact element itself and the housing containing it. The housing includes a support spring that provides mechanical support, while the lamella spring contact element can be treated with electron beam for conductivity enhancement. This segmentation allows independent optimization of each component's properties.
Solution Approach 2:
The housing acts as an intermediary structure that houses the lamella spring contact element. The support spring within the housing provides mechanical support and stability to the contact element, enabling the contact element to undergo electron beam treatment for conductivity enhancement without compromising overall spring properties.
2Reliability
If lamella spring contact surfaces are treated to prevent corrosion and wear, then electrical conductivity is maintained, but material is removed and spring properties are modified
Solution Approach 1:
By separating the contact element from the housing with support spring, the invention allows the contact element surface to be treated (e.g., electron beam treatment) to prevent corrosion and wear while maintaining electrical conductivity. The support spring in the housing compensates for any material removal effects and maintains spring properties.
Solution Approach 2:
The invention changes the structural parameters by introducing a housing with support spring that can compensate for material removal during surface treatment. This allows surface treatment to be applied to maintain electrical conductivity while the support spring adjusts to maintain mechanical spring properties despite composition changes.

AI summary
A housing for an electrical lamella spring contact, which is designed for the insertion of a pin contact, includes a lamella spring contact receptacle into which the lamella spring contact can be inserted along a longitudinal direction of the housing, wherein the housing has two side walls delimiting the lamella spring contact receptacle at adjacent sides, extending along the longitudinal direction and being at an angle to each other, and a support spring for supporting a spring portion of the lamella spring contact, the support spring extending from one side wall to the other side wall. A contact assembly is provided having the housing and a lamella spring contact disposed in the lamella spring contact receptacle and having a lamella spring supported by the support spring.
