Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting fabrics suffer from inferior light uniformity and limited color variety due to directional light sources and conspicuous connections between conducting lines and light sources, restricting their ability to display more complex colors.
Innovation Solution
A linear light-emitting module comprising isolated conducting wires covered by a light-guiding insulating material, with LED packages disposed between the wires, each connected to exposed local portions, allowing for uniform and varied color emission, and integrated into a textile product with a structure-reinforcing textile for enhanced strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional point light sources are used in light-emitting fabrics, then the structure is simple, but the light uniformity is inferior and color variety is limited
Solution Approach 1:
The patent segments the light source from the conducting line by using separate LED packages mounted on a substrate, with light-guiding insulating material directing light away from the conducting line. This segmentation allows the light emission to be uniform along the linear module while keeping the conducting line structure simple and separate.
Solution Approach 2:
The patent introduces light-guiding insulating material as an intermediary between the LED packages and the surrounding environment. This intermediary material guides and distributes the light uniformly along the linear module, preventing direct exposure of the conducting line while achieving uniform illumination.
2Device complexity
If conventional point light sources with directional limits are used, then the device complexity is low, but the light distribution and color display capability are limited
Solution Approach 1:
The patent uses multi-color LED packages that can emit different colors (red, green, blue, yellow, etc.) within the same linear light-emitting module. This multi-functionality allows the device to display a wide variety of colors and patterns without requiring multiple separate devices, maintaining simplicity while achieving versatility.
Solution Approach 2:
The patent enables dynamic color changing capability by incorporating multi-color LED packages that can be controlled to emit different colors. The linear light-emitting module can dynamically switch between various colors and display patterns, providing adaptability for different applications while maintaining a single unified structure.
3Ease of manufacture
If conducting lines and light sources are closely connected in conventional designs, then the connection is straightforward, but the connections become conspicuous and reduce light uniformity
Solution Approach 1:
The patent extracts the light-emitting function from the conducting line by using separate LED packages mounted on a substrate. The light-guiding insulating material further extracts and redirects the light away from the conducting line, making the conducting line invisible and achieving uniform light distribution without the conducting line being conspicuous.
4Adaptability or versatility
If flexible conducting wires are used for adaptability, then the adaptability to textile products is improved, but the tensile strength may be reduced
Solution Approach 1:
The patent uses a composite structure where flexible conducting wires are mounted on a flexible substrate with light-guiding insulating material. This composite construction combines the flexibility needed for textile integration with the structural integrity required for tensile strength, as the substrate and insulating material provide mechanical support to the conducting wires.
