Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single transmitter node performs both power transmission and data transmission functions, then the system complexity is reduced, but the transmission efficiency and reliability deteriorate due to inability to optimize each function separately
Solution Approach 1:
The patent divides the transmitter nodes into specialized groups: some nodes are dedicated to power transmission while others are dedicated to data transmission. This segmentation allows each node to optimize its specific function, improving overall transmission efficiency and reliability while the controller manages the distributed architecture to maintain system coherence.
2Device complexity
If the transmitter nodes continuously transmit both power and data, then the system operates simplistically without complex control, but energy waste increases due to inability to adapt to contextual conditions
Solution Approach 1:
The patent implements dynamic control where the controller continuously monitors contextual information including device properties, system configuration, and environmental conditions. Based on this real-time feedback, the controller dynamically adjusts which transmitter nodes perform power transmission and which perform data transmission, optimizing energy utilization and preventing waste while adapting to changing conditions.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller receives information about device state, environmental conditions, and transmission effectiveness. This feedback enables the controller to make informed decisions about resource allocation, adjusting power and data transmission assignments to minimize energy waste while maintaining operational efficiency.
3Ease of operation
If the system operates without contextual awareness, then the operational simplicity is maintained, but the reliability and safety deteriorate due to impractical or harmful operations
Solution Approach 1:
The patent enables the system to automatically monitor and respond to contextual conditions without requiring manual intervention. The controller autonomously assesses device properties, system configuration, and environmental factors, then adjusts transmission operations accordingly. This self-service capability maintains operational simplicity while significantly improving reliability and safety by preventing harmful operations through automated contextual awareness.
