Lens Bar Refraction Minimizes Multivision Frame Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multivision devices with multiple display units connected to form a large screen face challenges due to the presence of a visible frame part, which reduces user engagement and information transfer efficiency due to split screens.
Innovation Solution
A lens bar is attached to the frame part of the multivision device, featuring a design with a first surface that gradually converges towards the center and an air gap between the lens bar and the frame part, refracting light to create a virtual image of the frame, thereby reducing its perceived width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are connected to form a large screen, then the display area is increased, but the frame part becomes visible and reduces user engagement
Solution Approach 1:
A lens bar is introduced as an intermediary optical element between the frame part and the user's eye. The lens bar refracts light from the frame part, creating a virtual image that appears smaller and less intrusive. This mediator transforms the harmful visual effect of the frame into a minimized perception, allowing the frame to be physically present but visually reduced.
Solution Approach 2:
The patent replaces the mechanical approach of reducing frame width through structural modification with an optical solution. Instead of physically narrowing the frame, the lens bar uses optical refraction to substitute the mechanical reduction, achieving frame width reduction through light manipulation rather than structural change.
2Object-affected harmful factors
If the frame part width is reduced, then the split screen effect is minimized, but the structural support requirement increases
Solution Approach 1:
The lens bar serves as a mediator that allows the frame to maintain its structural width while visually reducing its perceived width. The frame can retain adequate structural support thickness, and the lens bar optically transforms this to minimize the split screen effect, decoupling structural requirements from visual perception.
Solution Approach 2:
The patent substitutes mechanical frame width reduction with an optical system. The frame maintains its structural integrity with sufficient width, and the lens bar uses optical refraction to replace the need for mechanical thinning, achieving the same visual effect through a different physical principle.
3Object-affected harmful factors
If a lens bar is added to reduce frame width, then the perceived frame width is reduced, but the device complexity increases
Solution Approach 1:
The lens bar utilizes optical properties (refraction and virtual image formation) to change the visual perception of the frame width. By manipulating how light interacts with the frame and user eye, the system achieves width reduction through optical transformation rather than physical modification, adding complexity only in the optical component.

Function Achieved in This Case
