Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power line communication is implemented in solar power generation systems, then communication function is achieved, but portability is impaired due to infrastructure connection requirements
Solution Approach 1:
The system is divided into independent circuit elements (energy harvesting elements and load elements) that can be individually connected and disconnected from the wiring member. Each element functions autonomously while being part of the power network, enabling portable configuration without permanent infrastructure installation.
Solution Approach 2:
The wiring member serves multiple functions: it provides mechanical connection structure, electrical power transmission path, and communication medium. This multi-functionality eliminates the need for separate communication infrastructure, achieving both communication capability and portability through a single integrated system.
2Ease of operation
If circuit elements are made detachable for portability, then ease of operation is improved, but connection reliability may deteriorate
Solution Approach 1:
The connector automatically performs both electrical connection and communication channel establishment when circuit elements are connected. The system self-configures the communication path through the power line, eliminating manual configuration and reducing potential connection errors, thereby maintaining reliability while enabling easy detachment.
3Speed
If power line data communication is implemented, then communication speed is improved through digital modulation, but system complexity increases
Solution Approach 1:
The existing power line infrastructure is utilized for both power transmission and data communication purposes. By superimposing modulated communication signals on the power line, the system achieves high-speed communication without adding separate communication wiring or infrastructure, thereby reducing overall system complexity despite the advanced communication capability.
