Existing wireless power transmission systems face challenges in supplying operating power to wireless power transmitters, particularly in lighting infrastructure, as they often require professional electrical wiring, which is costly and inconvenient.
Innovation Solution
Integrating wireless power transmitters and antenna elements into lighting devices, such as LED bulbs and fixtures, that can utilize existing electrical wiring infrastructure, allowing power to be supplied when the lighting device is coupled to a power source, and providing options for separate wireless power transmitters to connect via electrical cables or sockets, enabling continuous operation without the need for extensive rewiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless power transmitters are mounted in ceiling tiles or lighting fixtures, then wireless power transmission capability is improved, but installation complexity increases due to need for professional electrical wiring
Solution Approach 1:
The lighting device itself serves dual purposes: providing illumination and enabling wireless power transmission. The lighting fixture integrates the wireless power transmitter functionality, allowing it to serve its own purpose while assisting other devices, eliminating the need for separate wireless power infrastructure installation.
Solution Approach 2:
The lighting fixture is designed to perform multiple functions simultaneously: traditional lighting and wireless power transmission. By integrating the wireless power transmitter into the lighting device, a single component serves universal purposes, reducing overall system complexity and installation burden.
2Ease of manufacture
If wireless power transmitters are integrated into lighting devices, then installation cost is reduced by using existing electrical wiring, but device complexity increases
Solution Approach 1:
The wireless power transmitter circuitry and antenna elements are merged into the lighting device housing. This combination allows the system to utilize existing electrical wiring infrastructure for power delivery while integrating wireless transmission capabilities, reducing installation costs by avoiding separate wiring infrastructure.
Solution Approach 2:
The lighting device acts as an intermediary between the existing electrical wiring infrastructure and the wireless power transmission function. It converts incoming electrical power into wireless power signals, bridging the gap between traditional wired power delivery and modern wireless power needs.
3Adaptability or versatility
If separate wireless power transmitters are used to connect via electrical cables or sockets, then adaptability is improved, but reliability may be reduced compared to integrated solutions
Solution Approach 1:
The system allows segmentation between integrated and separate transmitter options. Lighting devices can be equipped with built-in transmitters for reliable integrated operation, or separate wireless power transmitters can be connected via electrical cables or sockets for flexible deployment scenarios, accommodating different installation needs while maintaining system functionality.
