Scuff Plate Light Guiding Protrusion Reduces Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scuff plates with light-emitting features face issues of increased thickness due to the need for a thick light guiding plate, which restricts leg motion and wiring space, and lack a three-dimensional design effect, resulting in uneven luminance and appearance.
Innovation Solution
A scuff plate design featuring a prism-like luminous unit with a luminous surface, a light source unit, and a plate-like light guiding unit with a luminous surface portion that expands intersectingly, allowing for reduced thickness and enhanced three-dimensional appearance both with and without light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional light guiding plate with flat plate shape is used, then the structure is simple, but the thickness is increased and three-dimensional effect is lost
Solution Approach 1:
The light guiding plate is transformed from a flat two-dimensional plate to a three-dimensional structure by adding a light guiding protrusion that extends in the thickness direction. This dimensional change allows the plate to maintain reduced overall thickness while creating functional depth for light guidance and reflection, resolving the contradiction between structural simplicity and thickness reduction.
Solution Approach 2:
The light guiding plate is segmented into multiple functional regions: a flat plate portion for structural support, a light guiding protrusion for light direction control, and a light reflecting surface for light redirection. This segmentation allows each portion to be optimized independently, achieving reduced thickness while maintaining simplicity through modular design.
2Length of stationary object
If the light guiding plate thickness is reduced, then leg motion is not restricted, but the quantity of light transmission is reduced
Solution Approach 1:
Instead of uniformly thickening the entire light guiding plate, the invention applies local quality enhancement by creating a light guiding protrusion with increased thickness only in the region where light guidance is needed. The light reflecting surface is concentrated on the tip of this protrusion, providing enhanced light reflection precisely where required, thus maintaining overall thinness while ensuring sufficient light transmission quantity.
3Illumination intensity
If a light reflecting layer is added on the rear surface, then light transmission quantity is improved, but device complexity and thickness are increased
Solution Approach 1:
The invention merges the light reflecting function with the light guiding structure by integrating a light reflecting surface directly onto the tip of the light guiding protrusion. This combination eliminates the need for a separate light reflecting layer on the rear surface, reducing structural complexity and thickness while maintaining effective light transmission quantity through the unified light guidance and reflection system.
