Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile sign plates lack a rich, multi-level colorful effect due to gaps on colorful edges, leading to an aesthetically flawed visual experience and increased energy consumption with LED lighting solutions.
Innovation Solution
An automobile sign plate design featuring a substrate with a colorful film and refraction portions generating patterns, surrounded by a highlight mirror surface chamfer portion forming a shielding groove to enhance light and shadow effects, improving aesthetic quality and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lights are used to light the automobile sign plates, then the visual effect is improved, but the energy consumption is increased and the structure becomes complicated
Solution Approach 1:
The patent replaces the LED lighting system (electrical/optical system) with a passive optical structure consisting of refraction portions and a highlight mirror surface chamfer portion. These structural features manipulate light from ambient sources through refraction and reflection to create colorful effects without requiring active lighting components, thereby eliminating the energy consumption and structural complexity associated with LED systems.
Solution Approach 2:
The sign plate structure itself serves the lighting function through its geometric features. The refraction portions and highlight mirror surface chamfer portion are integral parts of the sign plate that automatically manipulate light without requiring external control systems or power sources, making the system self-sufficient for achieving visual effects.
2Illumination intensity
If colorful film is used on automobile sign plates, then the colorful effect is improved, but the laying gap between the film and substrate creates aesthetic flaws
Solution Approach 1:
The highlight mirror surface chamfer portion acts as an intermediary element between the colorful film and the substrate. This chamfer portion creates a shielding groove that covers the laying gap, using the gap itself as a light-trapping feature that enhances the colorful effect through internal reflection, thereby converting an aesthetic flaw into a functional advantage.
Solution Approach 2:
The patent converts the harmful laying gap between the colorful film and substrate into a beneficial feature. By designing the highlight mirror surface chamfer portion to create a shielding groove around the gap, the gap becomes a light-trapping structure that enhances the colorful light and shadow effects through multiple internal reflections, turning a manufacturing defect into an aesthetic enhancement.
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 achieves a richer, multi-angle colorful effect by shielding gaps between the film and substrate, enhancing the light and shadow display while maintaining a lower cost and reduced energy consumption.
Implementation Method 1
a plurality of refraction portions for generating colorful patterns are arranged on the colorful film
Implementation Method 2
an outer side of the substrate is surrounded by a highlight mirror surface chamfer portion

AI summary
An automobile sign plate includes a substrate, where a colorful film for generating colorful light and shadow is laid on the substrate; a plurality of refraction portions for generating colorful patterns are arranged on the colorful film; an outer side of the substrate is surrounded by a highlight mirror surface chamfer portion; the top of the highlight mirror surface chamfer portion exceeds a surface, where the colorful film is laid, of the substrate. The highlight mirror surface chamfer portion will reflect natural light to be rendered as a halo of light and shadow outside the colorful light and shadow generated by the colorful film.
