Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If extension cords are used for temporary lighting, then power can be delivered to lighting equipment, but safety hazards increase due to cords running through the work area
Solution Approach 1:
The patent replaces the mechanical extension cord system with a wireless power transmission system using electromagnetic fields. The lighting equipment receives power wirelessly through electromagnetic coupling, eliminating the need for physical cords that create safety hazards in work areas.
2Use of energy by moving object
If multiple power outlets are required for temporary lighting, then lighting can be provided, but installation complexity and time increase
Solution Approach 1:
The patent creates a universal wireless power transmission system that can provide power to multiple lighting devices simultaneously without requiring separate outlets for each device. A single power source can serve multiple locations through electromagnetic field distribution, reducing installation time and complexity.
3Adaptability or versatility
If lighting components are made easily movable for reconfiguration, then customization is improved, but theft risk increases
Solution Approach 1:
The patent introduces an intermediary authentication system between the lighting components and power source. Each component has embedded identification that must be authenticated by the control system before receiving power, preventing unauthorized removal or theft while allowing legitimate reconfiguration.
4Adaptability or versatility
If standard right-hand threaded light bulbs are used, then compatibility with typical sockets is improved, but theft value increases
Solution Approach 1:
The patent employs asymmetric threading (left-hand threads instead of standard right-hand threads) on lighting components to reduce their theft value. This asymmetric design makes the components incompatible with standard sockets, thereby reducing their appeal to thieves while maintaining functionality within the controlled system.
5Use of energy by moving object
If high voltage power is used for lighting, then power efficiency is improved, but safety risks increase in wet or damp environments
Solution Approach 1:
The patent replaces high-voltage electrical transmission with wireless electromagnetic power transmission at lower voltages. This substitution maintains power efficiency while significantly reducing safety risks in wet or damp environments by eliminating the need for high-voltage connections and outlets.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides customizable, safe, and energy-efficient lighting with reduced theft risk, enabling easy installation and removal, and significant energy savings compared to traditional lighting systems.
Implementation Method 1
The rectifier may be a full bridge rectifier. The rectifier may be physically disposed in different locations such as being carried by the connector, being carried by the LED light module, or being carried on the power lead between the light module and the connector.
Data Source
AI summary
The disclosure provides an LED light system that is easy to install and customizable by the user. The LED lighting system may be plugged directly into an existing power source. In one configuration, the system includes a power supply that accepts standard power inputs. A low voltage bus line extends from the power supply. The user may connect LED light modules at essentially any location along a low voltage bus line of the system so that the light modules are located exactly where the user desires light. Uneven spacing is possible. Different size lights, different lumen powers, and different-colored light modules may be disposed along the low voltage bus line. Security features may be used to reduce the value of the system components to a thief.
