Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are required for LED lighting systems, then power supply reliability is improved, but installation flexibility and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless power transmission system using electromagnetic fields. The LED lighting system receives power wirelessly through a power receiver that converts electromagnetic energy to electrical energy, eliminating the need for physical wiring while maintaining power supply reliability and enabling flexible installation in any location within the wireless power field coverage area.
2Device complexity
If conventional power management is used, then system simplicity is maintained, but energy efficiency and loss of energy worsen
Solution Approach 1:
The patent implements a feedback mechanism where the control unit continuously monitors power consumption data from the LED lighting system and communicates with the power transmission system. Based on this feedback, the system dynamically adjusts power transmission parameters to optimize energy efficiency, reduce losses during peak demand periods, and extend battery operation time while maintaining relatively simple system architecture.
3Ease of operation
If wireless power transmission is implemented, then installation flexibility and ease of operation are improved, but device complexity and loss of energy may worsen
Solution Approach 1:
The patent merges multiple functions into integrated components: the power receiver simultaneously performs electromagnetic energy reception, conversion to electrical energy, and battery charging; the control unit integrates power management, communication, and system monitoring functions. This consolidation reduces the number of separate components and simplifies the overall system architecture while enabling wireless operation and flexible installation.
