Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the operating voltage is increased to meet high voltage requirements, then the power supply can provide higher voltage to devices to be tested, but the power dissipation increases causing temperature rise and heat dissipation issues
Solution Approach 1:
The patent implements dynamic adjustment of the operating voltage based on real-time detection of power consumption status. The control circuit automatically adjusts the operating voltage provided by the power module to the device power supply, ensuring that power dissipation remains within safe limits while maximizing voltage output capability when conditions permit
Solution Approach 2:
The patent employs a feedback mechanism where the control circuit detects the power consumption status of the device under test and uses this information to adjust the operating voltage. This closed-loop control ensures that the system responds to changing conditions and maintains optimal operation, preventing excessive temperature rise while meeting voltage requirements
2Power
If the supplied current is increased to meet high current requirements, then the power supply can provide higher current to devices to be tested, but the power dissipation increases requiring more aggressive heat dissipation
Solution Approach 1:
The system dynamically adjusts the operating voltage based on detected power consumption status. When high current is required, the control circuit lowers the operating voltage to compensate, maintaining power dissipation within acceptable limits while still delivering the required current to the device under test
Solution Approach 2:
The patent changes the operating voltage parameter in response to detected power consumption conditions. By adjusting this key parameter, the system optimizes the balance between current output capability and power dissipation, allowing high current delivery without excessive heat generation
3Power
If the heat dissipation structure is enhanced to manage higher power dissipation, then the power supply can sustain higher power levels, but the device complexity and size increase
Solution Approach 1:
The control circuit automatically detects power consumption status and adjusts the operating voltage without external intervention. This self-regulating mechanism prevents excessive power dissipation from occurring in the first place, eliminating the need for complex passive heat dissipation structures while maintaining safe operating limits
