Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lighting devices use uniform light emission or simple filters to achieve desired shapes or colors, then the device structure becomes mechanically complicated, but the design flexibility and ease of installation are limited
Solution Approach 1:
The patent replaces mechanical filter systems with an optical guide structure that uses total internal reflection and refractive index differences to achieve color and shape control. The optical guide part with specific refractive index (1.3-1.7) and patterned light source arrangement eliminates the need for mechanical filters while providing design flexibility for various shapes and colors.
Solution Approach 2:
The patent controls light emission characteristics by changing the refractive index parameter of the optical guide part (specified as 1.3-1.7) and adjusting the arrangement parameters of light sources at different positions. This allows dynamic control of beam shapes and colors without mechanical complexity.
2Adaptability or versatility
If conventional lighting devices use complex mechanical configurations to express desired atmospheric shapes or colors, then design freedom is limited, but installation and maintenance become difficult
Solution Approach 1:
The patent employs a thin optical guide part that can be flexibly installed on various surfaces. The optical guide structure with controlled refractive index allows the device to conform to different shapes and curves, providing installation ease while maintaining design freedom for various atmospheric expressions.
3Adaptability or versatility
If the lighting device uses a flexible sheet form with pattern design to create three-dimensional optical images, then design flexibility and installation ease are improved, but the optical path control complexity increases
Solution Approach 1:
The patent divides the light source into multiple segments positioned at different locations (first, second, and third positions) relative to the optical guide part. Each light source segment controls specific portions of the optical output, enabling three-dimensional image formation through coordinated emission patterns while simplifying overall optical path control.
Solution Approach 2:
The patent transitions from two-dimensional light emission to three-dimensional optical imaging by arranging light sources at multiple depth positions (first position at distance d1, second position at d2, third position at d3) relative to the optical guide part. This dimensional arrangement creates depth perception and three-dimensional effects in the emitted beams.
