Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional load resistances are used in load test apparatus, then the load test can be performed, but electric power energy is wasted as thermal energy
Solution Approach 1:
The patent changes the fundamental parameter of the load resistance from a passive dissipative element to an active energy storage element (storage battery). This parameter change transforms the energy flow from wasteful thermal dissipation to useful energy storage, directly resolving the energy waste problem while maintaining the load test functionality
Solution Approach 2:
The patent converts the harmful energy waste (thermal energy dissipation) into a beneficial outcome (energy storage). By replacing conventional load resistances with storage batteries, the previously wasted electric power energy is now stored and can be utilized for other purposes, turning a negative aspect into a positive feature
2Loss of energy
If storage batteries are used as load resistances, then energy can be stored effectively, but the device complexity increases
Solution Approach 1:
The storage batteries serve multiple functions: they act as load resistances for the load test, simultaneously function as energy storage devices, and can potentially serve as power sources for other applications. This multi-functionality reduces the need for separate dedicated components, thereby managing device complexity while achieving energy storage efficiency
Solution Approach 2:
The storage batteries are configured to automatically charge during the load test operation without requiring complex external control systems. The system utilizes the test power supply to directly charge the batteries, making the energy storage process self-service and minimizing the complexity of control circuits required
