1Productivity

If a conventional connecting structure is used, then the battery can be connected for testing, but the automatic connection becomes complex and the test efficiency is low

Engineering Contradiction:

Improvetest efficiencyVSAvoidconnecting structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The connecting structure is segmented into a limiting member and a conductive member that are spaced apart, forming a simplified automatic connection mechanism. The unit under test is placed in the space between these two members, with the conductive member elastically abutting against the test terminal to achieve automatic electrical connection without complex mechanical assemblies.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a complex mechanical connection mechanism to force connection, the patent inverts the approach by using elastic abutment where the conductive member passively contacts the test terminal through elasticity. This reversal from active mechanical driving to passive elastic contact simplifies the structure and improves test efficiency.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

Solution Approach 1:

The patent employs a simple conductive member with elastic abutment capability that can be easily manufactured and replaced. This approach replaces complex, expensive conventional connecting structures with a simpler, more cost-effective design that maintains reliable electrical connection while reducing test costs.

Inventive Principle:

Solution Approach 1:

The patent optimizes the elastic properties and geometric parameters of the conductive member to achieve the right balance between connection reliability and space occupation. By adjusting parameters such as elasticity modulus, cross-sectional area, and length, the conductive member provides stable electrical connection while occupying minimal space in the testing apparatus.
