Vehicle Light Marking Tool Using Reflective and Phosphorescent Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-light marking tools require a power supply for light emission and lack visibility at night, as only the reflection light emitting unit reflects or emits light, while other parts do not.
Innovation Solution
A vehicle-light marking tool with an attachment part, a first marking unit containing a reflective material for specular reflection, and a second marking unit containing a light-emitting material, such as fluorescent or phosphorescent materials, which emits light without a power supply, enhancing visibility at night.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a reflection light emitting unit with power supply is used, then light emission is achieved, but power supply is required and visibility is limited
Solution Approach 1:
The marking tool uses passive optical materials (reflective and light-emitting materials) that do not require external power supply. The reflective material reflects incident light, while the light-emitting material converts incident light into visible light, enabling the tool to serve itself without energy input from external sources.
Solution Approach 2:
The invention changes the optical parameters of the marking tool by incorporating materials with different optical properties - reflective material for specular/diffuse reflection and light-emitting material for photoluminescence/fluorescence. This allows the tool to exhibit different light interaction behaviors without requiring power supply.
2Illumination intensity
If only a reflection light emitting unit is provided, then light emission is achieved, but the area for light reflection/emission is limited
Solution Approach 1:
The invention merges two different optical marking units into one tool - a reflective material unit and a light-emitting material unit. This combination increases the total area that interacts with light, as both units can be distributed across different portions of the marking tool surface, thereby enhancing overall visibility without requiring power supply.
3Illumination intensity
If power supply is required for light emission, then light can be emitted, but device complexity increases
Solution Approach 1:
By using passive optical materials that do not require power supply, the invention eliminates the need for batteries, wiring, control circuits, and other power-related components. This self-service approach using reflective and light-emitting materials dramatically simplifies the device structure while maintaining light emission capability through optical rather than electrical means.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool provides excellent visibility at night without requiring a power supply by combining reflective and light-emitting materials, increasing the area that receives and shines light, thus improving recognition from a distance.
Implementation Method 1
a first marking unit that is provided on a side of the attachment part opposite from an attachment side, the first marking unit containing a reflective material
Implementation Method 2
a second marking unit that is provided adjacent to the first marking unit and contains a light-emitting material
Implementation Method 3
a second marking unit that is provided adjacent to the first marking unit and contains a light-emitting material
