Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light-signaling devices struggle to completely isolate electrical/electronic components from external environmental factors like humidity, leading to reduced performance and operational issues, particularly in outdoor applications.
Innovation Solution
The device incorporates an electronic lighting board with LEDs mounted on one side and electrical components on the rear, surrounded by a spacer panel and filled with an insulating material within an insulating volume defined by a perimeter frame, ensuring complete isolation of LEDs from the insulating material and external elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic board is housed inside a box-like body with protection systems, then the electrical and electronic components are protected from external environment, but the overall size and weight of the light-signaling device increase
Solution Approach 1:
The patent uses a thin transparent panel (front cover) that provides environmental protection while maintaining a compact structure. The panel is sealed around the periphery to create an enclosed space that protects electronic components from humidity and dust, eliminating the need for bulky box-like enclosures.
Solution Approach 2:
The patent extracts the essential protection function from a bulky box-like body and implements it through a thin sealed panel structure. Only the necessary sealing elements (peripheral seal, enclosed space) are retained, removing unnecessary structural mass while maintaining protection effectiveness.
2Reliability
If the electronic board is housed inside a box-like body, then the electrical and electronic components are protected from external environment, but the positioning and maintenance become difficult
Solution Approach 1:
The device is segmented into distinct functional modules: a removable electronic board, a sealed enclosure formed by the transparent panel, and mounting structures. This modular design allows the electronic board to be easily accessed, removed, and replaced without disassembling the entire protective structure, significantly improving maintenance ease.
Solution Approach 2:
The thin transparent panel creates a sealed protective environment while maintaining a sleek, low-profile structure that is easier to mount at various heights compared to bulky box-like enclosures. The sealed design protects components without requiring complex internal structuring.
3Reliability
If specific components are used to isolate electrical/electronic components from external environment, then protection from humidity is improved, but the production and assembly cost increase
Solution Approach 1:
The patent employs a simple thin transparent panel with peripheral sealing instead of complex multi-component protection systems. This approach uses fewer parts, reduces assembly steps, and lowers manufacturing costs while achieving effective environmental protection through a single sealed enclosure.
Solution Approach 2:
The patent combines multiple functions into the transparent panel structure: it serves as the front cover, the sealed enclosure wall, and the protective barrier against environmental factors. This integration eliminates the need for separate protection components, reducing both material costs and assembly complexity.

Function Achieved in This Case
This configuration effectively protects the LEDs from humidity and external damage, maintaining the quality and visibility of the light message, even in harsh outdoor conditions, while also simplifying positioning and maintenance.
Implementation Method 1
an insulating material is filled into an insulating volume defined by a perimeter frame, so that the insulating material is completely outside each LED seat, in such a way as to completely isolate the plurality of LEDs from the insulating material
