Braking Apparatus Anchoring Warning Triangles Against Wind
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Warning triangles placed behind stopped vehicles on highways can be blown over or away by strong winds, posing safety risks due to instability.
Innovation Solution
A warning triangle design featuring a base with walking devices, including active and passive rollers, and a braking apparatus that uses a resisting member and retaining mechanism to secure the device on the ground, preventing movement under wind pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning triangle is placed behind a stopped vehicle, then it provides visibility warning to following vehicles, but it may be blown over or blown away by strong wind
Solution Approach 1:
The base is divided into multiple sections with individual rollers (active and passive), allowing independent adjustment of each segment to adapt to ground conditions and maximize stability against wind forces
Solution Approach 2:
The warning triangle incorporates adjustable components including movable rollers and height-adjustable support legs, enabling dynamic adaptation to different ground conditions and wind strengths to maintain stability
Solution Approach 3:
The device allows changing parameters such as roller position, support leg length, and base orientation to optimize stability under varying wind conditions and ground surfaces
2Ease of operation
If the warning triangle has a simple base structure, then it is easy to deploy, but it cannot resist strong wind forces
Solution Approach 1:
The base incorporates movable rollers and adjustable support legs that can be quickly deployed while providing enhanced wind resistance through their ability to adapt to ground conditions and distribute wind loads
Solution Approach 2:
The base is segmented into multiple independent elements (rollers, support legs) that can be individually adjusted during deployment to optimize both ease of setup and wind resistance

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 triangle, ensuring it remains in place even in strong winds, enhancing safety by maintaining visibility for following vehicles.
Implementation Method 1
a braking apparatus (19) including a main body (191), a resisting member (192), and a retaining member (193)... the resisting member (192) abuts against the ground

AI summary
A self-applying braking apparatus to prevent wind-blown movement of a mobile device includes a main body, a resisting member, a retaining member, a pushing member, and a mounting member. The braking apparatus is mounted on an application device by the mounting member. The retaining member provides an elastic force to fix the main body on the application device. The resisting member is disposed on the main body and configured to abut the tarmac or ground to prevent the mobile device from moving. The pushing member is disposed on the main body and is configured to push the resisting member to abut the ground when blown by the wind or by turbulence from a passing vehicle in a predetermined direction, when greater than the elastic force. The braking apparatus prevents unwanted wind-blown movement.
