Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination systems fail to effectively mark the boundary between water bodies and road surfaces during submergence, posing safety risks for pedestrians and drivers, and lack waterproof properties.
Innovation Solution
An illumination system comprising a solid-state light source, a wavelength conversion element, a light guide tube with floating properties, and a connection member that secures the light guide tube to the road surface, allowing it to float and emit light during submergence while maintaining waterproof integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional illumination system is used to mark the boundary during submergence, then visibility is improved, but waterproof property and reliability deteriorate
Solution Approach 1:
The system divides the illumination function into separate components: a waterproof light source unit and a light guide tube. The light guide tube acts as an independent element that can float separately from the light source, allowing the light source to remain protected while the tube provides visibility in water.
Solution Approach 2:
The light guide tube serves as an intermediary between the waterproof light source and the water environment. It transmits light from the protected source to the water boundary area, enabling illumination without exposing electrical components to water.
2Stability of the object's composition
If the light guide tube is fixed firmly to the road surface, then stability is improved, but floating property during submergence deteriorates
Solution Approach 1:
The connection between the light guide tube and road surface is designed to be dynamic rather than fixed. The tube can transition between a connected state (providing stability on land) and a floating state (providing adaptability in water), allowing the system to adapt to different environmental conditions.
Solution Approach 2:
The light guide tube serves multiple functions: it provides stability when connected to the road surface during normal conditions, and it provides floating capability and boundary marking when separated during submergence events.
