Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery is fixed only in the vertical direction on the jig, then the battery charging and discharging test can be performed with simple fixing structure, but it is difficult to cope with various battery test environments
Solution Approach 1:
The patent applies the dynamics principle by making the jig body rotatable around a rotating shaft. The jig body can be rotated to different angles (0, 90, 180, or 270 degrees) to accommodate various battery test environments. This dynamic adjustment capability allows the same jig structure to adapt to different testing orientations without requiring multiple fixed jigs, thereby resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
The patent implements universality by designing a multi-functional jig that can perform battery charging and discharging tests in multiple orientations. The jig body with rotating capability serves as a universal platform that can handle different battery configurations and test environments, eliminating the need for separate specialized fixtures for each test condition.
2Adaptability or versatility
If the battery is fixed securely at various angles, then various battery test environments can be accommodated, but the fixing mechanism becomes more complex
Solution Approach 1:
The rotating mechanism allows the jig body to be dynamically adjusted to different angles while maintaining secure battery fixation. The rotation capability is integrated into the basic jig structure, providing angle variability without requiring complex additional fixing mechanisms for each orientation.
Solution Approach 2:
The patent merges the rotation function and battery fixation function into a single integrated jig body. The anode and cathode units are combined with the rotating jig structure, eliminating the need for separate fixation mechanisms for each angle and reducing overall system complexity.
3Adaptability or versatility
If the anode and cathode units are symmetrically installed on both sides of the mounting rails, then various battery configurations can be tested, but the device structure becomes more complex
Solution Approach 1:
The symmetrical arrangement of anode and cathode units on both sides of the mounting rails creates a universal configuration that can accommodate different battery types and terminal positions. This symmetric design allows the same jig structure to work with batteries having terminals on one side or both sides, providing versatility without requiring multiple specialized configurations.
Solution Approach 2:
While the overall arrangement is symmetrical, the patent allows for asymmetric positioning of individual components to accommodate specific battery configurations. The mounting rails and terminal connections can be adjusted asymmetrically within the symmetrical framework, enabling compatibility with different battery types while maintaining structural simplicity.

Implementation Method 3
a lever connected to the movable shaft, and configured to reciprocate the movable shaft by pushing or pulling the movable shaft
Implementation Method 4
a bearing bracket coupled to the outer circumference of the terminal body located in the support block, and configured to movably support the terminal body

AI summary
A jig for a battery charging and discharging test includes a first frame and a second frame which are disposed in parallel to each other so as to be spaced apart from each other. Two mounting rails are installed to protrude forward to connect the first and second frames, and have slit grooves open in directions facing each other. Each have an open side, such that the battery pack is mounted on the mounting rails through a rail-type structure. An anode unit and a cathode unit are arranged on either side of the mounting rails, and brought into contact with a first terminal and a second terminal of the battery pack coupled to the mounting rails, respectively. The jig can fix a battery at various angles to flexibly cope with various test environments, in order to perform a battery charging and discharging test.
