3D Stereoeffect Sign Using Vanishing Points for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with limited space and collision risks, traditional signs are difficult to install and recognize, leading to reduced visibility and increased construction costs.
Innovation Solution
A 3D stereoeffect sign is designed using vanishing points to create a stereoscopic effect, minimizing space requirements and protrusion height, and can be projected onto surfaces like roads and ceilings, with adjustable dimensions and color perspectives to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional vertical sign is installed to ensure clear visibility and readable instruction content, then visibility is improved, but extra space is required and construction costs increase
Solution Approach 1:
The patent applies dimensionality change by creating a 3D stereoscopic effect on a 2D flat surface. The sign uses perspective projection techniques with vanishing points to give the illusion of depth and volume, allowing the sign to appear three-dimensional while remaining physically flat and space-efficient. This resolves the contradiction by providing enhanced visibility through stereoscopic projection without requiring additional installation space.
2Illumination intensity
If a protruding sign structure is installed to increase visibility and attention, then visibility is improved, but collision risk with moving cars or viewers increases
Solution Approach 1:
The patent uses optical copying techniques to create a virtual three-dimensional image on a flat surface. Instead of building a physical protruding structure that could cause collisions, the invention projects a stereoscopic copy of a 3D sign onto a 2D plane. This optical copy provides the same visibility enhancement and attention-grabbing effect without the physical hazards of protruding structures.
3Loss of information
If a sign is installed in a narrow passage or tunnel section to provide information, then information delivery is improved, but the sign is not easily recognized due to deviation from sight range
Solution Approach 1:
The patent applies parameter changes by modifying the visual parameters of the sign through stereoscopic projection. By using perspective distortion, vanishing points, and depth cues in the projection design, the sign creates a strong visual effect that attracts viewer attention and enhances detectability. The altered visual parameters make the sign stand out and easier to recognize even in constrained environments like tunnels or narrow passages.

AI summary
A manufacturing method of a 3D stereoeffect sign includes designing a figure or a character having specific information, giving a volume to the figure or the character by providing one or more vanishing points, setting a projection height of the figure or the character having the volume which is projected to the eyes of a viewer which is located at a reference distance, setting a printed length of the figure or the character having the volume to correspond to the projection height, setting a printed width of the figure or the character having the volume, and adjusting the length and the width of the figure or the character having the volume proportionally to correspond to the printed length and the printed width.
