Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special floating structures are installed on the insulation housing to enable simultaneous axial and radial floating, then the conductive component can absorb axial and radial errors, but the structure becomes complex and manufacturing costs increase
Solution Approach 1:
The conductive component is divided into an outer conductive shell and an inner conductive body that are separable. The inner conductive body can float independently within the outer conductive shell, allowing axial and radial error absorption without requiring complex floating structures on the insulation housing. This segmentation enables independent movement of the inner conductive body while maintaining electrical connection.
Solution Approach 2:
The inner conductive body is nested within the outer conductive shell, with the inner body having a smaller outer diameter than the inner diameter of the outer shell. This nested configuration allows the inner conductive body to float freely in both axial and radial directions while maintaining electrical contact, achieving error absorption with a simple structure.
2Ease of manufacture
If a simple structure is used for the electrical connection assembly, then manufacturing costs and complexity are reduced, but the ability to simultaneously absorb axial and radial errors may be compromised
Solution Approach 1:
The inner conductive body is designed to be dynamically movable within the outer conductive shell, allowing it to float in axial and radial directions to absorb positioning errors. The elastic part provides dynamic electrical contact that maintains connectivity while accommodating movement, achieving both manufacturing simplicity and error absorption capability.
Solution Approach 2:
The diameter parameters are specifically designed such that the outer diameter of the inner conductive body is smaller than the inner diameter of the outer conductive shell. This parameter difference creates the necessary clearance for floating movement while maintaining electrical contact, enabling error absorption with a simple structure.

AI summary
An electrical connection assembly includes an outer conductive shell and an inner conductive body. The outer conductive shell has an annular wall with an upper periphery and a lower periphery axially opposite each other, an elastic part connected to the upper periphery, and a connection part connected to the lower periphery. The inner conductive body is installed in the outer conductive shell and is axially clamped between the elastic part and the connection part. An outer diameter of the inner conductive body is smaller than an inner diameter of the outer conductive shell. The inner conductive body floats axially and radially relative to the outer conductive shell and maintains electrical contact with the outer conductive shell.
