Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional RF communication systems are used, then simple system structure is maintained, but power transmission efficiency deteriorates in obstructed environments
Solution Approach 1:
The patent introduces reflector devices as intermediary elements between RF transmitters and receivers. These reflectors dynamically adjust to redirect RF signals around physical obstructions, enabling efficient power transmission without requiring direct line-of-sight between transmitter and receiver, thus resolving the contradiction between transmission efficiency and system complexity
Solution Approach 2:
The system employs dynamically controllable reflector devices that can adjust their orientation and positioning in real-time based on environmental conditions and receiver locations. This dynamic adaptability allows the system to maintain high power transmission efficiency in changing obstructed environments without requiring a completely complex reconfiguration of the entire RF network
2Area of stationary object
If RF signals are transmitted through physical obstructions, then coverage area is maintained, but power transmission efficiency deteriorates
Solution Approach 1:
The patent utilizes spatial dimensionality by deploying reflector devices at different positions and orientations in three-dimensional space. Instead of attempting to penetrate obstructions directly, the system routes RF signals around obstacles using multiple spatial paths created by strategically positioned reflectors, thereby maintaining coverage area while preserving power transmission efficiency
Solution Approach 2:
The RF communication path is segmented into multiple hops involving transmitters, reflectors, and receivers. By breaking the direct transmission path into segments connected through intermediate reflector devices, the system can navigate around obstructions while maintaining efficient power transfer across the entire coverage area
3Productivity
If intelligent power transmission control is implemented, then power delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms where reflector devices and transceivers communicate to share information about signal quality, receiver locations, and environmental conditions. This feedback enables intelligent power transmission control that optimizes power delivery efficiency while managing system complexity through coordinated, information-driven decision-making among network components
