Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack the ability to create a strong visual impact and fail to replicate the appearance of a stainless-steel surface with polishing marks effectively.
Innovation Solution
A light guide with multiple adjacent light exit areas that change the direction of incident light rays, emitting them in a way that mimics the random directionality and streaky patterns of polishing marks on stainless steel, using strip-shaped light exit parts with varying orientations to create a stereoscopic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional light guide structures are used, then the display appears uniform and flat, but the visual impact is weak and lacks stereoscopic effect
Solution Approach 1:
The light guide applies local quality by creating different light emission characteristics in different regions. Each light exit area has light exit parts with specific orientations that emit light in particular directions, creating localized variations in light distribution. This results in a non-uniform appearance that mimics polishing marks on stainless steel, enhancing visual impact while maintaining overall structural integrity.
Solution Approach 2:
The invention employs asymmetry by configuring light exit parts with random orientations across different light exit areas. Instead of uniform symmetric structures, each light exit area has light exit parts oriented in different directions, creating an asymmetric pattern that resembles the random polishing marks on stainless steel surfaces, thereby achieving strong visual impact.
2Shape
If light rays are emitted in fixed directions, then the light distribution is controlled, but the appearance lacks the random pattern of polishing marks
Solution Approach 1:
The light guide is segmented into multiple light exit areas, each containing multiple light exit parts. This segmentation allows independent configuration of each light exit area with specific orientations, enabling the creation of random patterns through systematic division. Each segment can be optimized for its specific directional requirements while contributing to the overall random appearance.
Solution Approach 2:
The invention changes the orientation parameter of light exit parts across different light exit areas. By varying the orientation angle and direction of light exit parts in each region, the system creates random light emission patterns. This parameter variation transforms controlled fixed-direction emission into appearance-random patterns that mimic polishing marks.
3Shape
If multiple light exit areas with different orientations are created, then the stereoscopic effect is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The light guide structure copies the characteristic pattern of polishing marks on stainless steel surfaces. By replicating the random orientation and distribution patterns of polishing marks through light exit parts, the invention achieves the desired stereoscopic effect without requiring extremely high manufacturing precision. The copied pattern provides visual authenticity while maintaining manufacturability.

AI summary
A light guide guides incident light rays and emits some of the incident light rays from a light exit surface. The light guide includes a plurality of light exit areas arranged adjacent to one another and configured to change directions of the incident light rays and emit the incident light rays from the light exit surface. Each of the light exit areas includes a plurality of light exit parts in which directions of light rays with maximum intensities out of light rays to be emitted are substantially the same. The light exit parts in each of the light exit areas are configured so that the directions of the light rays with the maximum intensities out of the light rays to be emitted from each of the light exit areas are random. Each of the light exit areas has a strip shape, and lengths of the light exit areas are random.
