Projection System Transparent Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection systems face challenges in reducing the impact of shadow and screen blocking caused by support structure components, which degrades image projection quality.
Innovation Solution
The projection system incorporates a light transmission part in the support structure component that allows light rays to pass through, ensuring the connecting parts are out of the light rays' path, thereby preventing blocking and minimizing shadow formation, and optimizing the light transmission part's shape using exponential equations to reduce distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a non-transparent mechanical structure is used to support the projection screen, then the screen can be properly supported and positioned, but it blocks light rays and produces shadows on the screen, degrading image quality
Solution Approach 1:
The support structure component changes its optical property from non-transparent to transparent, allowing light rays to pass through. This resolves the contradiction by maintaining structural support capability while eliminating the harmful shadow effect on the projection screen.
Solution Approach 2:
The optical parameter (transparency) of the support structure component is changed from opaque to transparent. This parameter change allows the same structural component to fulfill both support function and light transmission function simultaneously.
2Area of stationary object
If multiple screen units are spliced using a projection array splicing method to obtain a large-size projection screen, then the projection size is increased, but overlap areas or merged areas are created at edge connections, affecting image quality
Solution Approach 1:
The transparent support structure component acts as an intermediary element at the edge connections between screen units. It provides mechanical support and positioning while being optically invisible, thereby eliminating the visual disruption caused by traditional opaque support structures at the splice edges.
3Object-affected harmful factors
If a light transmission part is introduced into the support structure component to allow light passage, then shadow and screen blocking are reduced, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The support structure component is made from transparent material that combines structural support properties with optical transparency. This composite material approach allows the single component to fulfill both mechanical support function and light transmission function, avoiding the need for complex assemblies and simplifying manufacturing.
