Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired testing is performed at the test station, then testing coverage is ensured, but test cycle length increases and test efficiency decreases
Solution Approach 1:
The patent performs wireless testing before the battery arrives at the test station, completing certain test items in advance. This preliminary action reduces the number of tests needed at the test station, thereby shortening the test cycle while maintaining comprehensive testing coverage through the combination of wireless and wired tests.
2Reliability
If wired testing is performed at the test station, then testing coverage is ensured, but test efficiency decreases
Solution Approach 1:
By performing wireless testing before the battery reaches the test station, the system completes certain test items in advance. This reduces the workload at the test station and improves overall test efficiency, while the combination of wireless and wired testing ensures comprehensive coverage.
Solution Approach 2:
The patent replaces wired mechanical connections with wireless communication for certain test functions. This substitution eliminates the need for physical contact and complex wiring at the test station, improving test efficiency while maintaining testing coverage through the complementary wired tests.
3Loss of time
If wireless testing is implemented, then test cycle is shortened and test efficiency is improved, but communication complexity increases
Solution Approach 1:
The patent divides the testing system into two parts: wireless communication module for pre-testing and wired test station for final testing. This segmentation allows wireless testing to handle certain functions independently, shortening the test cycle, while the wired station handles remaining tests, managing overall system complexity through functional division.
