Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light guide plates experience image misalignment and blurring when the incident angle from the light source is small, making it difficult to form a clear image in space.
Innovation Solution
A light guide plate design featuring a curved emission surface and a bent light introduction portion, which connects near a 90-degree angle, allowing for improved image formation and reduced blurring by optimizing the incident angle and preventing dead spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flat light guide plate is used, then the structure is simple, but the incident angle is small causing image misalignment and blurring
Solution Approach 1:
The light guide plate employs a curved emission surface instead of a flat surface. The curvature is specifically designed to increase the incident angle of light from the light source, thereby improving image formation precision and reducing blurring while maintaining structural simplicity
2Manufacturing precision
If the incident angle is increased to improve image formation, then image clarity improves, but the light guide plate design becomes more complex
Solution Approach 1:
The curved emission surface is designed with a specific radius of curvature that optimizes the incident angle without requiring complex multi-component structures. This single curved surface achieves both improved image clarity and manufacturing simplicity
3Manufacturing precision
If a curved emission surface is used, then image formation is improved and dead space is prevented, but manufacturing complexity increases
Solution Approach 1:
The light guide plate integrates the light introduction portion and light emitting portion into a single molded piece. This merging of functions into one component simplifies manufacturing processes while maintaining the curved surface geometry needed for optimal image formation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design facilitates easier image formation, reduces blurring, and simplifies manufacturing by allowing for a more efficient light distribution and alignment, enhancing the visibility of the image in space.
Implementation Method 1
The light emitting portion includes a curved emission surface for emitting light from the light source which is incident from the light introduction portion, and is bent and connected to the light introduction portion. Since the curved emission surface is bent and connected to the light introduction portion, the incident angle from the light introduction portion to the light emitting portion nears 90 degrees
