Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gilded block is used for testing, then initial testing accuracy is maintained, but testing accuracy deteriorates over time due to mechanical wear and oxidation
Solution Approach 1:
The patent removes the gilded block from the testing system entirely. Instead of using a gilded block that degrades over time, the invention directly contacts the probe with the module's steel component, eliminating the intermediate gilded block that causes wear and oxidation problems. This extraction of the problematic component resolves the contradiction between initial accuracy and long-term stability.
Solution Approach 2:
The patent changes the material contact interface from gilded block to direct probe-to-steel contact. By modifying the material parameters and contact characteristics, the system achieves both initial testing accuracy and long-term stability without the degradation issues associated with gilded blocks.
2Stability of the object's composition
If a gilded block is used for testing, then initial contact stability is maintained, but contact stability deteriorates over time due to mechanical wear
Solution Approach 1:
The patent extracts the gilded block from the contact chain, creating a direct contact between the probe and the module's steel component. This eliminates the mechanical wear that occurs at the gilded block interface, thereby maintaining contact stability throughout the extended service life without degradation.
3Measurement precision
If direct probe-to-module contact is implemented, then wear is reduced and accuracy is improved, but device complexity increases due to additional positioning mechanisms
Solution Approach 1:
The patent segments the positioning function into separate components: a pressure plate for applying contact force and moving mechanisms for positioning. This segmentation allows each component to perform its specific function efficiently, achieving accurate direct contact while organizing the complexity into manageable, modular segments.
Solution Approach 2:
The moving mechanisms serve multiple functions: they position the pressure plate, apply controlled contact force, and maintain stable contact during testing. By making these mechanisms multi-functional, the patent reduces the need for separate dedicated components, thereby managing device complexity while achieving the desired direct contact capability.

AI summary
A test fixture includes a fixed base for placing a module and probes. The fixed base defines threading needle holes, and the threading needle holes communicate with a surface of the fixed base adjacent to the module. The probes are connected with a tester and extend through the threading needle holes to contact with the module placed on the fixed base. The tester is capable of testing the module. When the module is disposed on the fixed base, the probes are directly connected with the module for testing, a gilded block between the module and the probes is omitted for improving a stability and an accuracy of test results. An early warning system is also disclosed.
