Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED indicator light systems for display devices often require separate mounting plates and complex wiring, limiting design flexibility and increasing costs due to the simultaneous arrangement of light source and indicator lights on the same surface.
Innovation Solution
An LED light bar with a substrate hosting both light source and indicator light components on opposite surfaces, connected via an interface, allowing independent control and eliminating the need for additional mounting plates and wiring, while enabling flexible placement and reduced substrate size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light source component and indicator light component are arranged on the same surface, then the structure is simple, but they interfere with each other positionally and require separate mounting plates
Solution Approach 1:
The patent transitions from arranging light source and indicator components on the same two-dimensional surface to utilizing opposite surfaces of the substrate (front and back surfaces), effectively adding a third dimension to the layout. This resolves the positional interference issue while maintaining structural simplicity, as the components are now separated in the Z-direction rather than competing for space on the XY-plane.
2Manufacturing precision
If separate mounting plates are used for light source and indicator lights, then positioning is precise, but the device complexity and cost increase
Solution Approach 1:
The patent merges the mounting functions by placing both the light source component and indicator light component on a single substrate, eliminating the need for separate mounting plates. The substrate serves as a unified mounting platform with an interface layer that provides electrical connections for both component types, thereby reducing structural complexity and assembly steps while maintaining precise positioning through the integrated design.
3Adaptability or versatility
If multiple separate components are used for light source and indicator lights, then functionality is independent, but the wiring and manufacturing complexity increase
Solution Approach 1:
The substrate is designed as a multi-functional platform that simultaneously provides mechanical support, positioning, and electrical connection functions for both the light source component and indicator light component. The interface layer on the substrate integrates the wiring structure, allowing both components to be independently controlled while simplifying the overall wiring architecture and manufacturing process.
