Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a shading device is used to block light to determine PV module location, then location determination precision is improved, but power output of the PV module decreases
Solution Approach 1:
The patent converts the harmful effect of light blocking (power loss) into a beneficial signal for location determination. By intentionally shading the PV module and measuring the resulting power decrease, the system identifies the module's location through the correlation between shading event and power response, transforming a negative impact into a useful measurement mechanism
2Measurement precision
If GPS parameter data is obtained continuously to determine PV module location, then location accuracy is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by obtaining GPS parameter data only at specific moments when shading events occur or are detected, rather than continuously. This approach maintains location accuracy by capturing GPS coordinates at relevant time points while significantly reducing energy consumption by avoiding unnecessary continuous GPS operations
3Adaptability or versatility
If a separate mapping device is used for previously installed PV modules, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a mapping device that can serve multiple functions: it can determine locations for newly installed PV modules through integrated sensors and processing, and also map previously installed modules by receiving their operational parameter data from existing systems. This multi-functional approach enhances adaptability while avoiding the need for entirely separate systems for different installation scenarios
