Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing fan testing systems use fixed testing configurations, then testing simplicity is maintained, but testing versatility across different application scenarios deteriorates
Solution Approach 1:
The testing system employs adjustable load apparatus with variable resistance values that can be dynamically changed to simulate different application scenarios. The load resistance can be adjusted according to different device power consumption characteristics, enabling the same testing system to adapt to various fan applications without requiring multiple fixed testing configurations.
Solution Approach 2:
The system changes key testing parameters including load resistance values, power supply voltages, and testing conditions to match different application scenarios. By varying these parameters, the testing system can evaluate fan performance under diverse operating conditions while maintaining a single unified testing platform.
2Measurement precision
If fan testing is performed in multiple application scenarios, then testing accuracy is improved, but testing time increases
Solution Approach 1:
The testing system enables continuous testing across multiple application scenarios by rapidly adjusting load resistance and power supply parameters without requiring physical reconfiguration. The automated control apparatus can sequentially test fans under different loading conditions, maintaining continuous testing operation and reducing idle time between different scenario evaluations.
Solution Approach 2:
Different application scenario configurations are pre-programmed into the control apparatus, including various load resistance values and power supply parameters. This preliminary setup allows the testing system to quickly switch between scenarios without time-consuming manual adjustments, thereby improving testing efficiency while maintaining comprehensive scenario coverage.
