Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety signs for outsized payloads are not effectively visible in poor visibility conditions, posing a hazard due to inadequate visibility and range, especially in foggy, dusty, or snowy conditions, at night, and during transportation.
Innovation Solution
A unibody safety indicator with an elastically deformable frame and a planar flag body, integrally formed as a single unit, providing enhanced visibility through high visibility colors or electroluminescent coatings, and designed to be affixed to outsized payloads for increased visibility and evasion of hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional safety signs are used for outsized payloads, then the basic warning function is provided, but visibility is insufficient in poor visibility conditions (foggy, dusty, snowy, night)
Solution Approach 1:
The safety indicator employs high-visibility color combinations (such as fluorescent yellow-green, orange-red, or phosphorescent materials) that enhance contrast against various background conditions. The flag body and frame utilize colors specifically selected for their visibility characteristics in foggy, dusty, snowy, and nighttime environments, directly addressing the visibility deficiency of traditional safety signs.
Solution Approach 2:
The patent introduces an electroluminescent coating as an intermediary layer on the flag body surface. This coating acts as a mediator that converts electrical energy to light energy, providing active illumination enhancement. The electroluminescent material serves as an intermediate between the passive flag body and the observer, amplifying the warning signal in poor visibility conditions.
2Area of stationary object
If safety signs are made larger to increase visibility range, then the warning range is extended, but the device complexity and material requirements increase
Solution Approach 1:
The safety indicator merges the frame and flag body into a single integrated unibody structure. The frame and flag body are formed as one piece through injection molding or stamping processes, eliminating separate components and assembly steps. This merging reduces structural complexity while maintaining the enlarged area needed for extended visibility range.
Solution Approach 2:
The unibody structure serves multiple functions simultaneously: it provides the structural framework, carries the high-visibility flag body, enables elastic deformation for deployment, and integrates mounting features. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity while achieving the required visibility range.
3Ease of operation
If safety indicators use multiple separate components for flexibility and deployment, then the ease of operation is improved, but material discontinuities and manufacturing complexity increase
Solution Approach 1:
The frame is designed with elastic deformability, allowing it to dynamically adjust during deployment and operation. The elastic material enables the frame to flex and adapt to various payload shapes and deployment conditions without requiring multiple rigid components. This dynamic flexibility achieves ease of operation while maintaining a simpler, more integrated manufacturing process.
Solution Approach 2:
The patent utilizes changes in material parameters (elasticity, viscosity, temperature response) to achieve deployment flexibility. The frame material is selected with specific elastic properties that allow it to be compressed for storage and then expand to its full operational shape. This parameter-based flexibility eliminates the need for complex mechanical joints and multiple components, reducing manufacturing complexity.
