Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used for power and control in LED lighting systems, then power supply stability and control reliability are improved, but installation flexibility and adaptability to different locations deteriorate
Solution Approach 1:
The system divides the lighting installation into independent wireless modules that can be deployed separately without requiring centralized wired infrastructure. Each module operates autonomously with its own power and control capabilities, enabling flexible placement while maintaining system reliability through modular redundancy.
Solution Approach 2:
The patent replaces physical wired connections with wireless communication technologies (RF, infrared, optical) for both power transmission and control signals. This substitution eliminates the mechanical constraint of wires, allowing lights to be installed in locations that would be difficult or expensive to wire while maintaining reliable remote control and power supply.
2Duration of action of stationary object
If wired power connections are required for LED lighting, then continuous power supply is ensured, but installation complexity and cost increase
Solution Approach 1:
The system dynamically adapts power delivery based on real-time conditions, using wireless power transfer technologies that can adjust transmission levels and methods. This allows continuous power supply to be maintained while simplifying installation, as the system can accommodate varying distances, obstacles, and power requirements without requiring fixed wired infrastructure.
Solution Approach 2:
The patent introduces wireless power transmission as an intermediary between the power source and LED lights, using technologies such as radio frequency energy harvesting, optical wireless power transfer, or inductive coupling. This intermediary enables power delivery without direct physical connection, reducing installation complexity while ensuring continuous power supply through reliable wireless transmission channels.
3Device complexity
If traditional lighting control methods are used, then system simplicity is maintained, but energy efficiency and peak demand management deteriorate
Solution Approach 1:
The wireless control system incorporates feedback mechanisms where lights report their operational status, power consumption, and environmental conditions to a central controller or cloud platform. This feedback enables real-time optimization of energy usage, dimming schedules, and load management, significantly reducing overall energy consumption and peak demand while maintaining simple user interaction through wireless interfaces.
Solution Approach 2:
The system implements periodic control actions such as scheduled dimming during peak pricing periods, cyclic on/off patterns for energy savings, and regular status checks. These periodic wireless control commands optimize energy consumption without requiring complex user intervention, automatically reducing energy loss during high-demand periods while maintaining system simplicity.
4Adaptability or versatility
If wireless power and control systems are implemented, then installation flexibility and energy efficiency are improved, but system complexity and initial cost increase
Solution Approach 1:
The wireless lighting system is designed with universal components that can perform multiple functions: wireless power reception, wireless control signal processing, status monitoring, and communication. This multi-functionality reduces the need for separate specialized devices, thereby managing system complexity while maximizing installation flexibility and adaptability across different environments and applications.
Data Source
AI summary
In embodiments of the present invention improved capabilities are described for providing intelligent power control in response to an external power interruption, causing a processor is in an electrical fixture to interrogate an external power control switch to gain an understanding of the switch's state, where prior to the external power interruption the electrical fixture may be powered by external power and where external power may be connected and disconnected by a user of the switch. In the event that the switch's state is determined to be such that it would normally pass power to the electrical fixture, the processor causes the electrical fixture to operate using a backup power supply. In the event that the switch's state is determined to be such that it would normally not pass power to the electrical fixture, the processor causes the electrical fixture to act as if the user of the switch has intentionally removed power. In response to a return of external power, powering the electrical fixture is then through external power where the user of the switch switches external power.
