Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input method is used for array building, then installation process is simple, but time consumption and error rate increase significantly
Solution Approach 1:
The patent replaces the manual mechanical input process with an automated electronic system. Photovoltaic modules are equipped with communication units that automatically transmit ID information, and servers automatically calculate position information using triangulation based on reference signals. This substitution eliminates manual data entry while maintaining operational simplicity.
Solution Approach 2:
The photovoltaic modules perform self-identification by automatically transmitting their ID information through communication units. The system enables self-positioning by automatically calculating coordinates based on reference signals received from multiple communication devices. This self-service mechanism eliminates the need for manual information input during installation.
2Device complexity
If manual input method is used for array building, then system complexity is low, but error rate and convenience deteriorate
Solution Approach 1:
The patent replaces error-prone manual input with automated electronic communication and calculation systems. Communication units transmit ID information electronically, and servers calculate position coordinates using triangulation algorithms based on reference signals. This electronic substitution significantly improves accuracy while maintaining reasonable system complexity through modular design.
Solution Approach 2:
The patent introduces communication devices and servers as intermediaries between photovoltaic modules and the array building process. These intermediaries automatically extract ID information, calculate position coordinates, and match network information, thereby eliminating direct manual input errors while maintaining system manageability through standardized communication protocols.
3Productivity
If automated system is implemented, then efficiency and accuracy improve, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into existing photovoltaic module components. Communication units that were originally designed for monitoring purposes are repurposed to transmit ID information for array building. The inverter system handles both power conversion and position calculation tasks. This multi-functionality approach increases productivity without proportionally increasing device complexity.
Solution Approach 2:
The patent uses software-based solutions to replicate manual processes automatically. The server creates a digital copy of the array configuration by calculating position coordinates and matching network information based on received reference signals. This virtual modeling approach enables automated array building without requiring additional physical hardware components.
4Ease of manufacture
If manual input is used, then installation cost is low, but time loss and labor requirements increase
Solution Approach 1:
The photovoltaic modules automatically provide their identification information through built-in communication units, eliminating the need for manual data collection. The system performs self-positioning by automatically calculating coordinates from reference signals. This self-service capability reduces labor time and associated costs while maintaining economical implementation through existing module components.
Solution Approach 2:
The patent replaces labor-intensive manual information input with automated electronic communication and computational processes. Communication units transmit ID data electronically, and servers automatically calculate positions using triangulation algorithms. This substitution reduces both direct labor costs and indirect time losses during the installation process.
