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 becomes difficult
Solution Approach 1:
The patent combines the testing function with the integrated storage and charging machine itself by using its internal energy storage module, first voltage conversion module, and second voltage conversion module to form a self-contained testing system, eliminating the need for external charging and discharging equipment
Solution Approach 2:
The integrated storage and charging machine performs self-testing by utilizing its own internal modules (energy storage module, voltage conversion modules, and switch modules) to conduct charging and discharging tests without requiring external service equipment, thereby reducing test costs and enabling on-site debugging
2Reliability
If external charging and discharging equipment is used for testing, then module functionality can be tested, but test efficiency decreases due to equipment restrictions
Solution Approach 1:
The testing functionality is merged into the integrated storage and charging machine by configuring internal modules (energy storage module connected to both voltage conversion modules through switch modules) that can perform charging and discharging tests independently, removing restrictions imposed by external test equipment and locations
