Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external charging and discharging equipment is used for testing, then testing can be performed, but test costs increase and on-site debugging is limited
Solution Approach 1:
The patent combines the testing function with the integrated storage and charging machine itself by using internal modules (first voltage conversion module, second voltage conversion module, energy storage module, and switch modules) to form test loops. This eliminates the need for external testing equipment, reducing test costs and enabling on-site debugging while maintaining reliability testing capabilities.
Solution Approach 2:
The integrated storage and charging machine is designed with multi-functionality, serving both as the operational system and as its own testing apparatus. The internal modules can operate in dual modes: normal charging/discharging operations and testing operations, allowing the system to perform self-diagnosis and validation without requiring separate dedicated testing equipment.
2Reliability
If external charging and discharging equipment is used for testing, then module functions can be tested, but on-site debugging is not facilitated
Solution Approach 1:
The system performs self-testing through internally formed test loops using the switch modules and voltage conversion modules. The integrated storage and charging machine tests its own modules without external assistance, enabling operators to conduct on-site debugging independently. The control module automatically manages the testing process by controlling switch module states to form appropriate test loops.
3Ease of manufacture
If internal test loops are formed using switch modules, then test costs are reduced, but system complexity increases
Solution Approach 1:
The switch modules dynamically reconfigure the circuit topology to form different test loops as needed. By controlling the on-off states of the switch modules, the system can flexibly create various testing configurations using the same physical components, avoiding the need for additional dedicated testing circuitry while maintaining the ability to test different module combinations.
