Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warning and traffic signs face challenges in increasing visibility, especially in inclement weather or when drivers are distracted or under the influence, as they do not effectively draw attention to themselves.
Innovation Solution
A sign post flasher assembly with elongated channels housing light sources, such as LEDs, connected via electrically conductive material and sealed with a waterproof covering, which can be affixed to sign posts to enhance visibility through controlled flashing, compatible with various sign types and weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional static warning signs are used, then the signs provide basic traffic information, but they fail to increase visibility and draw attention in adverse conditions
Solution Approach 1:
The patent applies periodic action by implementing flashing LED light sources that activate in rhythmic patterns to draw attention to traffic signs. The controller system enables lights to flash on and off at predetermined intervals, creating visual attention-grabbing effects that static signs cannot achieve. This periodic illumination significantly enhances visibility and alerts drivers, especially in adverse weather conditions or low-visibility environments.
2Illumination intensity
If light sources are exposed without protection, then they provide maximum visibility, but they become vulnerable to water damage and environmental factors
Solution Approach 1:
The patent employs flexible shells and thin films by using waterproof sealants and protective coatings on the LED light sources and housing structures. These flexible protective layers seal the light sources within the sign assembly, preventing water ingress while maintaining the structural integrity and flexibility needed for various installation environments. The waterproofing allows the lights to operate reliably in rain, snow, and other adverse weather conditions.
3Reliability
If multiple light sources are used to enhance visibility, then attention-drawing capability improves, but system complexity and potential failure points increase
Solution Approach 1:
The patent applies segmentation by dividing the lighting system into multiple independent LED light sources, each capable of operating autonomously or in coordinated patterns. This segmentation allows the system to provide enhanced visibility through multiple light points while maintaining modularity. If one LED fails, others continue to function, and the segmented design simplifies maintenance and replacement procedures.
Solution Approach 2:
The patent implements beforehand cushioning by incorporating redundant LED light sources and a robust controller system that can accommodate individual light source failures. The system is designed with built-in tolerance for component failure, ensuring continuous operation and maintained attention-drawing capability even when some LEDs malfunction. This prior cushioning against failure enhances overall system reliability.
4Object-affected harmful factors
If lights are sealed waterproof, then environmental resistance improves, but electrical connectivity and light emission may be compromised
Solution Approach 1:
The patent uses intermediary substances and components, specifically waterproof gel sealants and hermetic sealing materials, to bridge the gap between electrical components and the external environment. These intermediary materials provide waterproof protection while maintaining electrical connectivity through specialized conductive pathways and sealed connectors. The gel sealants fill gaps and crevices around LED modules and wiring, creating water-tight barriers without compromising electrical function.

Function Achieved in This Case
The solution significantly increases the visibility of signs day and night, particularly in adverse conditions, by providing additional attention-drawing light sources that can operate underwater and are not affected by single LED failures, ensuring consistent safety.
