Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional reflecting mask is used to guide light, then light distribution can be adjusted, but the light distribution diversity is limited and the structure cannot adapt to different light sources
Solution Approach 1:
The patent uses a light guide element with a curved outer surface that incorporates total internal reflection to achieve diverse light distributions. The curved geometry enables multiple reflection paths and angles, providing adaptability to different light sources without requiring complex mechanical adjustments or multiple components.
2Adaptability or versatility
If a secondary optical element is used to change light distribution, then light form can be adjusted, but a recess must be disposed in the center to receive the light source, requiring structural changes for different light sources which increases cost
Solution Approach 1:
The light guide element is designed as a separate, modular component that can be independently manufactured and then integrated with different light sources. This segmentation allows the optical element to remain unchanged while accommodating various light sources, eliminating the need for costly structural modifications and reducing manufacturing costs.
3Use of energy by moving object
If conventional lamps are used, then simple structure is maintained, but power consumption is high and light distribution control is limited
Solution Approach 1:
The patent replaces conventional mechanical light control methods (such as rotating reflectors or adjustable masks) with a statically optimized light guide element that uses total internal reflection. This substitution eliminates the need for moving parts and complex control mechanisms while achieving superior light distribution control and energy efficiency.

AI summary
A light guide element and a lamp are provided. The light guide element includes a light-incident surface, a light-emitting surface, an outer surface and an inner surface. The light-incident surface has a first outer peripheral edge and a first inner peripheral edge. The light-emitting surface is opposite to the light-incident surface and has a second outer peripheral edge and a second inner peripheral edge. The outer surface connects the first outer peripheral edge and the second outer peripheral edge. The inner surface connects the first inner peripheral edge and the second inner peripheral edge. A first opening defined by the inner surface adjacent to the first inner peripheral edge is larger than a second opening defined by the inner surface adjacent to the second inner peripheral edge.
