Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual wiring test boards are used for circuit testing, then testing can be performed with simple equipment, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The testing system performs self-positioning and self-testing operations. The testing device automatically locates circuit nodes and executes testing procedures without requiring manual manipulation of test boards, enabling the system to serve itself in the testing process.
Solution Approach 2:
The patent replaces manual mechanical operations with automated systems. Instead of operators physically handling wiring test boards and manipulating connectors, an automated testing device with positioning capabilities performs all testing operations, substituting mechanical human labor with automated mechanical systems.
2Device complexity
If manual manipulation of wiring test boards is required, then equipment complexity can be reduced, but operator skill and time requirements increase
Solution Approach 1:
The testing device is divided into functional segments including positioning mechanisms, testing components, and control systems. This segmentation allows each component to perform its specific function independently, reducing the overall operational complexity while maintaining comprehensive testing capabilities.
Solution Approach 2:
The testing device incorporates dynamic positioning capabilities that allow it to adaptively locate and access different circuit nodes. The device can dynamically adjust its position and orientation based on the testing requirements, eliminating the need for operators to manually manipulate fixed test boards for different test points.
3Reliability
If wiring test boards are used for node testing, then electrical interfaces can be established, but the process becomes labor intensive and less accurate
Solution Approach 1:
The patent replaces manual mechanical testing operations with automated electronic positioning and testing systems. The automated device establishes electrical interfaces through programmed movements and automated connector engagement, eliminating manual manipulation while improving both reliability and automation level simultaneously.
