Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If LED lamps are used to replace traditional lighting devices, then power consumption is reduced and working life is extended, but glare effect is generated
Solution Approach 1:
The light-emitting surface is segmented into multiple light-emitting elements arranged in a matrix, with each element independently controllable. This segmentation allows the light to be distributed more evenly across the surface, reducing concentrated glare while maintaining overall illumination efficiency.
Solution Approach 2:
The patent transitions from traditional point-source or linear LED lighting to a two-dimensional matrix array of light-emitting elements. This dimensional change enables light to be emitted from multiple points simultaneously, creating a broader, more diffuse illumination pattern that reduces glare while covering a wider area.
2Illumination intensity
If traditional lighting devices are used, then illumination is provided, but heat generation is high and power consumption is high
Solution Approach 1:
The patent changes the physical parameters of light emission by using multiple low-power LED elements instead of a single high-power source. This parameter change allows the same total luminous flux to be achieved with lower individual element power consumption, and the distributed arrangement reduces heat concentration at any single point.
3Duration of action of stationary object
If LED lamps are used, then working life is extended, but glare effect limits effectiveness for indoor illumination
Solution Approach 1:
By dividing the lighting system into multiple independently controllable LED elements, the patent can optimize illumination patterns for different indoor applications. This segmentation allows adjustment of which elements are active and at what intensity, improving adaptability to various indoor lighting needs while maintaining the long working life of LEDs.
