Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bolt and nut are fastened with misaligned central axes in actual work sites, then the fastening becomes inaccurate and unstable, but the threads may break and become unusable
Solution Approach 1:
The patent applies preliminary action by performing fastening tests at various inclined angles before actual deployment. The test apparatus pre-adjusts the bolt and nut to specific misaligned angles (e.g., 0°, 0.1°, 0.2°, etc.) to simulate real-world conditions and identify the maximum tolerable angle, thereby preventing thread breakage in actual applications.
Solution Approach 2:
The patent uses copying by creating a test model that replicates real-world fastening conditions. The test apparatus copies the misalignment scenario by adjusting the angle between the bolt's central axis and the nut's central axis to match actual work site conditions, allowing accurate prediction of fastening performance without risking actual components.
2Reliability
If fastening tests are performed at various angles to ensure accurate fastening, then the reliability of fastening improves, but the testing time and complexity increase
Solution Approach 1:
The patent applies dynamics by implementing an automated angle adjustment mechanism that can dynamically change the inclination angle between the bolt and nut during testing. The test apparatus can automatically adjust to multiple predetermined angles (0°, 0.1°, 0.2°, etc.) and perform fastening tests at each angle, significantly reducing the time required compared to manual repositioning while maintaining comprehensive testing coverage.
3Measurement precision
If the test apparatus includes multiple adjustment mechanisms for angle and position, then the testing precision improves, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional test apparatus that combines angle adjustment, position control, and fastening testing in a single integrated system. The apparatus can perform multiple functions: adjusting the inclination angle of the bolt, controlling the descent speed of the nut, measuring fastening angles, and conducting repeated tests at set angles, thereby reducing the need for separate devices while maintaining high measurement precision.
