Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional lighting equipment is used, then lighting power and range are sufficient, but weight increases and mobility decreases
Solution Approach 1:
The patent changes the fundamental parameters of the lighting system by using LED technology instead of conventional bulbs, and by implementing wireless transmission of light data via radio frequency. This allows the lighting equipment to achieve sufficient lighting power and range while dramatically reducing weight and improving mobility.
Solution Approach 2:
The patent replaces traditional mechanical lighting components with wireless electronic systems. The light source transmits light data wirelessly to a receiver, eliminating the need for physical light guides and mechanical coupling mechanisms, thereby reducing weight while maintaining lighting functionality.
2Ease of operation
If conventional lighting equipment is used, then lighting functionality is provided, but attachment difficulty increases
Solution Approach 1:
The patent extracts the attachment mechanism from the lighting system by using wireless communication instead of physical connections. The light source and receiver are separate components that communicate wirelessly, eliminating complex mechanical attachment mechanisms while maintaining full lighting functionality.
Solution Approach 2:
The wireless receiver is designed to work with multiple types of light sources and can be attached to various surfaces, providing universal attachment capability. The receiver serves multiple functions including receiving light data, converting it to visible light, and providing attachment functionality, thereby simplifying the overall system.
3Illumination intensity
If conventional lighting equipment is used, then lighting is provided, but color rendering is non-optimum
Solution Approach 1:
The patent implements dynamic control of the LED light source, allowing the color temperature to be adjusted from 2000K to 10000K. This dynamic capability enables optimal color rendering for different lighting conditions and applications while maintaining cost-effectiveness through the use of standard LED components and wireless communication technology.
