Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional testing systems are used for electrical cables, then each different test can be conducted with specialized equipment, but the process requires repeated reconfiguration and disconnection of cables making it time-consuming and inefficient
Solution Approach 1:
The patent combines multiple specialized test equipment (EMI test equipment, PD test equipment, temperature rise test equipment) into a single integrated testing system. The system includes multiple test modules that can be simultaneously connected to the cable under test through a unified interface, eliminating the need for repeated disconnections and reconfigurations while maintaining the measurement capabilities of each individual test type.
Solution Approach 2:
The integrated testing system is designed to perform multiple different tests (EMI, PD, temperature rise) on the same cable sample without requiring separate specialized equipment for each test. The system provides universal testing capability through a common platform that can accommodate various test modules and configurations.
2Adaptability or versatility
If conventional testing systems require repeated reconfiguration for each test, then specialized equipment can be used for each specific test type, but the process becomes complex and inefficient
Solution Approach 1:
The integrated testing system is divided into distinct test modules (EMI test module, PD test module, temperature rise test module), each responsible for a specific test type. This segmentation allows each module to be independently designed and optimized for its specific function while being part of a unified system, reducing the complexity of managing multiple separate systems.
Solution Approach 2:
The system provides a universal platform that can perform multiple different test types through integrated modules. The unified interface and common control system allow the same physical setup to accommodate various test configurations, reducing the need for repeated reconfiguration while maintaining test flexibility and adaptability.
3Reliability
If multiple tests are conducted sequentially with reconfiguration, then each test can be performed with appropriate equipment, but the overall testing process becomes time-consuming
Solution Approach 1:
The system merges multiple test capabilities into a single integrated platform where EMI, PD, and temperature rise tests can be conducted simultaneously on the same cable sample. This eliminates the sequential nature of conventional testing, allowing parallel execution of multiple tests and significantly improving productivity while maintaining reliable measurement through dedicated test modules.
Solution Approach 2:
The integrated testing system enables continuous testing by eliminating the interruptions caused by repeated disconnections and reconfigurations. Once the cable is connected to the system, multiple tests can proceed continuously without breaking the test setup, maximizing the useful action time and improving overall testing efficiency.
