Hinged Rescue Plate Assembly for Continuous Vehicle Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rescue plates face difficulties in maintaining continuity over large sunken ground areas, leading to skidding issues when wheels pass through gaps between plates, which increases escape time and difficulty.
Innovation Solution
A vehicle rescue device comprising a first and second rescue plate connected via a detachable connecting shaft and plate, forming a hinged structure that increases overall length and reduces skidding by enhancing connection strength and elasticity, while allowing easy assembly and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple rescue plates are sequentially placed end to end to assist vehicle escaping from continuous sunken ground, then the coverage area is increased, but the continuity between plates deteriorates causing skidding phenomenon
Solution Approach 1:
The patent connects multiple rescue plates together through connecting portions (including connecting shafts and connecting grooves) to form an integrated structure. This merging approach ensures continuity between adjacent plates, preventing skidding when vehicle wheels pass through the joints, while maintaining the increased coverage area needed for continuous sunken ground.
Solution Approach 2:
The rescue plate system is divided into modular units with standardized connecting portions. Each rescue plate can be independently manufactured and stored, then assembled into longer continuous structures when needed. This segmentation allows the system to adapt to different sunken ground lengths while maintaining reliability through standardized connections.
2Length of stationary object
If multiple rescue plates are connected to increase overall length, then the continuity is improved, but the device complexity increases
Solution Approach 1:
The connecting portions are designed with universal applicability, where connecting shafts and connecting grooves can join any adjacent rescue plates regardless of position or orientation. This standardized interface simplifies the connection process and reduces operational complexity, allowing rescuers to quickly assemble long continuous structures without dealing with different connection mechanisms for different scenarios.
3Adaptability or versatility
If rescue plates are connected in a hinged manner, then the adaptability to terrain is improved, but the connection strength may be reduced
Solution Approach 1:
The connecting shaft and connecting groove form a hinged connection that allows dynamic adjustment. The connecting shaft can rotate within the connecting groove to adapt to uneven terrain and settlement differences between adjacent plates, while the limiting portions prevent excessive movement. This dynamic capability maintains connection strength while providing terrain adaptability.
