Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If repeated thermal shock tests are conducted to determine pumping-out performance, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent creates a simplified test model using a support plate and press plate that replicates the essential pumping-out mechanism without requiring repeated thermal shock cycles. The press plate method copies the functional effect of thermal shock on thermal grease displacement, enabling single-cycle assessment of pumping-out performance while maintaining measurement precision.
Solution Approach 2:
The patent extracts the core pumping-out mechanism from the complex thermal shock test environment. By isolating the essential elements (support plate, press plate, thermal grease) and removing unnecessary components (repeated heating/cooling cycles), the method achieves accurate pumping-out performance determination in a single operation, significantly reducing test time while preserving measurement validity.
2Productivity
If a simple test method is used to reduce test time, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The press plate test method creates a functional copy of the thermal shock test's pumping-out effect. By replicating the essential displacement mechanism using a simple press plate structure, the patent achieves both high productivity (single-cycle testing) and maintained measurement precision (accurate pumping-out performance assessment).
Solution Approach 2:
The patent changes the test parameters from repeated thermal cycles to a single mechanical pressing action. By transforming the test methodology from time-intensive thermal shock repetition to a single press plate operation with controlled displacement, the patent simultaneously improves productivity while preserving measurement precision through proper parameter control.

AI summary
A test method of the present disclosure includes: applying a thermal grease on a support plate; placing a press plate such that the press plate faces the support plate with the thermal grease interposed between the press plate and the support plate; changing a distance between the support plate and the press plate; and observing a shape of the thermal grease after the distance between the support plate and the press plate is changed. The pumping-out performance is determined based on the shape of the thermal grease.
