Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power line communication is implemented using existing infrastructure, then communication capability is achieved, but device portability is impaired
Solution Approach 1:
The system is divided into independent circuit elements (energy harvesting elements, load elements, switching elements) that can be freely connected and disconnected via connectors. Each element can independently participate in power line communication without requiring fixed infrastructure installation, thereby achieving both communication capability and device portability
Solution Approach 2:
The connectors serve multiple functions: they establish electrical connections for power transmission and simultaneously enable data communication through the same power line. This multi-functionality allows devices to communicate without dedicated communication infrastructure, maintaining portability while achieving communication capability
2Ease of manufacture
If energy harvesting elements are used to generate power, then infrastructure maintenance is reduced, but reverse current protection is required
Solution Approach 1:
Energy harvesting elements automatically generate power from available energy sources (light, heat, etc.) without requiring external power supply infrastructure or maintenance. The reverse current prevention units are integrated into each element, providing automatic protection without adding external complexity to the overall system
Solution Approach 2:
Reverse current prevention units act as intermediary protective elements between energy harvesting elements and the rest of the circuit. These units block reverse current flow while allowing forward current transmission, adding localized protection without significantly increasing overall system complexity
