Warning Bracket With Rotating Ground Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warning structures on roads, such as warning triangles, are prone to being displaced by wind, which compromises their effectiveness in emergency situations.
Innovation Solution
A bracket with a rotating mechanism and stopping assembly that engages with the ground to prevent movement, utilizing rollers and a resilient member to stabilize the structure against external forces like wind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a warning structure uses rollers to facilitate placement on the ground, then ease of operation is improved, but stability under wind force deteriorates
Solution Approach 1:
The bracket employs a dynamic stopping assembly with a rotating mechanism that can transition between retracted and engaged states. The stopping member rotates from a retracted position (during placement) to an engaged position where it contacts the ground, providing stability against wind while maintaining ease of operation during deployment
Solution Approach 2:
The resilient member pre-biases the stopping mechanism into a position where the stopping member is ready to engage with the ground. This preliminary positioning ensures that when wind force acts on the bracket, the stopping member is already prepared to provide counteracting stability without requiring additional activation
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 solution effectively anchors the warning structure, ensuring it remains in position even under windy conditions, thereby enhancing its stability and reliability during emergencies.
Implementation Method 1
a resilient member connecting the rotating mechanism to the first extending member, the resilient member being configured to bias the protruding portion to contact the first extending member
Implementation Method 2
a plurality of rollers rotationally mounted to the main body

AI summary
A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a rotating mechanism and a stopping member coupled to the rotating mechanism. The rotating mechanism is rotationally coupled to the main body. One of the rollers is mounted adjacent to the stopping member. When the rotating mechanism is rotated, the stopping member is engaged with a ground to prevent the bracket from moving.
