Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting is used to provide horizontal illumination, then energy efficiency is improved, but vertical and upper area illumination becomes insufficient
Solution Approach 1:
The lighting apparatus is divided into multiple independent subassemblies, each with specific functions: some subassemblies contain reflectors for directing light horizontally, while others contain diffusers for distributing light vertically and upward. This segmentation allows each component to optimize its performance for its specific illumination direction without compromising overall energy efficiency.
Solution Approach 2:
The patent transitions from traditional single-directional LED lighting to multi-dimensional illumination by incorporating both horizontal (reflected light) and vertical/upward (diffused light) components. This dimensional expansion ensures comprehensive coverage of all spatial zones including upper areas that were previously under-illuminated.
2Illumination intensity
If traditional lighting technologies are used, then adequate illumination is provided, but energy consumption increases and maintenance requirements increase
Solution Approach 1:
The patent changes the operational parameters of LED lighting by adjusting the distribution of light across different directions and intensities. By optimizing the balance between reflected and diffused light components, the system achieves adequate illumination levels while maintaining the energy efficiency advantages of LED technology.
3Illumination intensity
If traditional lighting technologies are used, then illumination is provided, but maintenance frequency increases
Solution Approach 1:
The modular subassembly design enables self-service maintenance capabilities. Individual subassemblies can be independently accessed, removed, and replaced without requiring complete fixture disassembly or complex maintenance procedures. This reduces maintenance frequency and simplifies operational requirements while maintaining adequate illumination.
4Use of energy by moving object
If LED lighting directs light horizontally, then energy efficiency is improved, but visual appeal from multiple angles is reduced
Solution Approach 1:
The lighting system is segmented into directional components: reflector subassemblies for horizontal light distribution and diffuser subassemblies for vertical and upward light distribution. This segmentation enables the system to maintain energy efficiency while providing visual appeal from multiple viewing angles through coordinated operation of different light-directed components.
Solution Approach 2:
The patent adds vertical and upward illumination dimensions to the traditional horizontal LED lighting approach. This dimensional expansion creates visually appealing light distribution from ceiling, wall, and floor perspectives while maintaining the energy efficiency of LED technology through optimized light path management.
