Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warning triangles for motor vehicles face issues of increased center of gravity, stability, weight, and production costs due to complex constructions and heavy designs, particularly when folded for transport.
Innovation Solution
A warning triangle design featuring a horizontal base bar in the shape of an inverted 'T' with wire feet and rotating ball joints, allowing for reduced weight and dimensions while enhancing stability through an aerodynamic shape and optimized foot placement, enabling lower production costs and improved competitiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the feet are connected to the stand with hinges positioned below the horizontal plane of the lower edge of the base, then the triangle can be folded to compact dimensions for transport, but the center of gravity is raised and stability is reduced
Solution Approach 1:
The patent inverts the conventional hinge positioning by placing the hinge connection point above the horizontal plane of the lower edge of the base instead of below it. This inversion allows the feet to be connected in a way that lowers the center of gravity while still enabling compact folding, thus resolving the contradiction between folded dimensions and stability
Solution Approach 2:
The patent introduces a vertical dimension element by positioning the hinge connection point at a specific height above the base plane. This dimensional change allows the feet to extend downward from the hinge point, lowering the center of gravity and improving stability while maintaining the ability to fold compactly
2Stability of the object's composition
If complex constructions and heavy designs are used to improve stability, then the warning triangle can maintain stability, but the weight and production costs increase
Solution Approach 1:
The patent extracts and eliminates unnecessary complex construction elements from the design. By using a simplified hinge connection system where feet are rotatably connected at a point above the base plane, the design achieves stability without requiring heavy or complex structural components, thus reducing weight while maintaining stability
Solution Approach 2:
The patent changes the key parameter of hinge connection position from below the base plane to above it. This parameter change fundamentally alters the center of gravity position and stability characteristics, allowing for a lighter design that maintains or improves stability without complex constructions
3Stability of the object's composition
If the feet are positioned to lower the center of gravity and improve stability, then the warning triangle gains stability, but the design complexity increases
Solution Approach 1:
The patent merges the hinge connection function with the structural support function into a single integrated element. The hinge connection point served above the base plane simultaneously provides rotational movement capability and structural support, eliminating the need for separate complex mechanisms and reducing overall design complexity while maintaining stability

AI summary
The triangle has an inverted-T shaped, horizontally positioned base rail (2) comprising sockets (22) at two end parts for rotatably receiving rotatable ball-and-socket joints (71) of wire stands (7), if horizontal longitudinal axis of the stands is parallel to horizontal longitudinal axis of the base rail. The sockets are formed as horizontal U-profiles, where a lower arm of the U-profile is formed under a horizontally surface of the base rail in the form of inverted T, such that the lower arm is inwardly opened in one direction.
