Leather Workpiece Light-Transmitting Substrate Brightness Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leather accessories lack effective methods to enhance their ornamental properties with a light-emitting effect without compromising their appearance, as existing solutions like reflective or fluorescent sheets have low brightness and embedding LEDs alters the appearance in undesirable ways.
Innovation Solution
A leather workpiece design incorporating a light-transmitting substrate, adhesive layers, a light-transmitting intermediate layer, a circuit board, and a light-emitting element group, where the illumination beam passes through the substrate and intermediate layer to create a light-emitting surface pattern, maintaining the accessory's appearance while enhancing its ornamental properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective sheet or fluorescent sheet is disposed on the leather surface, then the ornamental properties are improved, but the brightness is low and light-emitting effect is insufficient
Solution Approach 1:
The patent introduces a light-transmitting substrate as an intermediary layer between the LED light source and the leather surface. This substrate allows the light to pass through while maintaining the leather's appearance, effectively mediating between the light-emitting function and the ornamental requirement without compromising either aspect
2Illumination intensity
If LEDs are embedded on the leather surface, then the brightness is improved, but the appearance of the leather accessory is affected
Solution Approach 1:
The light-transmitting substrate serves as a mediator that separates the LED light source from the leather surface. The LEDs are positioned on the circuit board beneath the substrate, allowing light emission while the substrate maintains the leather's aesthetic appearance, thus resolving the contradiction between brightness and appearance
Solution Approach 2:
The patent moves the LED light source from the surface dimension (embedded in leather) to the subsurface dimension (positioned on the circuit board below the light-transmitting substrate). This dimensional shift allows the light to emanate from behind the substrate, preserving the leather's appearance while achieving bright illumination
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 solution generates a light-emitting effect at the surface pattern, improving the leather workpiece's ornamental properties while preserving its appearance, and potentially reducing the number of light sources needed, thus lowering costs.
Implementation Method 1
a light-emitting element group disposed on the circuit board and adapted to emit an illumination beam
Implementation Method 2
The illumination beam sequentially passes through the first adhesive layer and the surface pattern of the first light-transmitting substrate

AI summary
A leather workpiece is adapted to emit a light at a surface pattern, and includes a first light-transmitting substrate, a first adhesive layer, a second light-transmitting substrate, a circuit board, and a light-emitting element group. The first adhesive layer is disposed between the first light-transmitting substrate and the second light-transmitting substrate. The circuit board is fixed on the second light-transmitting substrate. The light-emitting element group is disposed on the circuit board and is configured to emit an illumination beam. The first light-transmitting substrate has the surface pattern on a surface opposite to the first adhesive layer. The illumination beam sequentially passes through the first adhesive layer and the surface pattern of the first light-transmitting substrate, so that the leather workpiece emits the light at the surface pattern. A manufacturing method of the leather workpiece is also provided.
