Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warning triangle structures are prone to being blown away by wind, necessitating a design that can withstand wind resistance while serving as an effective traffic alert.
Innovation Solution
The warning triangle structure incorporates a base, a triangle with reflective materials, connecting rods, and a support wheel, along with a braking device that includes a transmission shaft and a braking mechanism, such as a brake motor or worm gear reducer, to stabilize and self-propel the structure, ensuring it meets wind-resistant standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional warning triangle structure is used, then it can serve as a traffic alert, but it is easy to be blown away by wind
Solution Approach 1:
The patent applies the dynamics principle by making the warning triangle structure movable rather than fixed. The triangle can rotate and adjust its position on the base, allowing it to dynamically adapt to wind forces. The support wheel enables the structure to move and reposition itself, transforming from a static vulnerable design to a dynamic wind-resistant system that can actively respond to environmental conditions.
Solution Approach 2:
The patent implements parameter changes by modifying the structural parameters of the warning triangle. Key parameters include: adding a base with specific dimensions (length and width), incorporating a support wheel with defined radius, and designing connecting rods with specific lengths. These parameter changes transform the conventional triangle into a more complex but wind-resistant structure that meets the ECE R27 standard requirements.
2Stability of the object's composition
If a base with connecting rods and support wheel is added to improve wind resistance, then the structure becomes more stable, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the warning triangle system into distinct functional components: a base structure, connecting rods, a support wheel, and a triangle assembly. Each component has a specific function and can be independently analyzed or manufactured. This segmentation allows for modular design where each part contributes to overall stability without requiring complete redesign of the entire system.
Solution Approach 2:
The patent uses intermediaries to connect different components and reduce direct complexity. The connecting rods act as intermediaries between the base and the triangle, providing a mechanical link that allows movement while maintaining structural integrity. The support wheel serves as an intermediary that enables the triangle to move relative to the base, facilitating wind resistance without requiring direct rigid connections throughout the entire structure.

Function Achieved in This Case
The design effectively resists wind and meets European regulation ECE R27 standards by using the braking device and support wheel to maintain stability and mobility, ensuring the structure remains visible and functional in windy conditions.

AI summary
A warning triangle structure includes a base, a triangle, a number of connecting rods, and a braking device. The triangle includes a bottom end and a top end opposite the bottom end. The bottom end is fixedly mounted to the base. Each of the connecting rods includes a first end and a second end. The first end is fixedly coupled to the base, and the second end is mounted with a rotatable support wheel. The braking device is installed at the second end of at least one of the connecting rods. The braking device includes a transmission shaft coupled to the support wheel. The braking device controls the support wheel to stop rotating by stopping the transmission shaft from rotating.
