Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional testing methods are used for solar panels, then the testing process is simple, but the measurement precision and ability to detect performance degradation is insufficient
Solution Approach 1:
The test apparatus is divided into modular functional components: a control unit for coordinating measurements, a measurement unit for capturing electrical parameters, and a comparison unit for analyzing performance degradation. This segmentation allows each module to be optimized independently while maintaining overall system precision without excessive complexity.
Solution Approach 2:
The patent introduces an intermediary test apparatus that acts as a mediator between the solar panel and the measurement system. This intermediary device standardizes the measurement process by providing controlled electrical loads and measurement protocols, thereby improving measurement precision without requiring direct complex integration with the solar panel itself.
2Measurement precision
If comprehensive performance testing is conducted on solar panels, then the assessment accuracy is improved, but the testing time and productivity are reduced
Solution Approach 1:
The test apparatus performs preliminary automated setup and configuration before actual measurements begin. The control unit pre-configures measurement parameters, connects appropriate electrical loads, and prepares data structures in advance, which eliminates time-consuming manual setup during the actual testing process while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The measurement unit continuously captures electrical parameters throughout the testing process without interruption. By maintaining continuous measurement of current, voltage, and power across different operating conditions, the system achieves comprehensive performance assessment without requiring multiple separate testing sessions, thereby improving productivity.
3Loss of information
If multiple measurement parameters are monitored simultaneously, then the information completeness is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The measurement unit is designed as a universal multi-functional device that can measure multiple electrical parameters (current, voltage, power, impedance) simultaneously using integrated sensors and processing circuits. This multi-functionality is achieved within a single energy-efficient module rather than through multiple separate measurement devices, thereby maintaining information completeness while controlling energy consumption.
Solution Approach 2:
The control unit dynamically adjusts measurement parameters based on the specific testing requirements and solar panel operating conditions. By changing measurement ranges, sampling rates, and active sensors according to real-time conditions, the system monitors comprehensive parameters only when necessary, reducing unnecessary energy consumption while maintaining complete information availability.
