Adjustable Stabiliser Device for Vehicle Rescue Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stabilization systems for vehicles after accidents require multiple wedges or shims of different sizes, which are cumbersome to position and adjust, and often require re-stabilization when the vehicle is partially or completely overturned, hindering efficient rescue operations.
Innovation Solution
A stabilizer device with height adjustment means, including an exteriorly-threaded elongated rod and locking mechanisms, allows for precise positioning and automatic re-stabilization without the need for multiple wedges, featuring a ball joint for angular adjustment and elastic means for secure locking, along with a pusher element for increased bearing and clamping surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wedges or shims of different sizes are used to stabilize the vehicle, then the vehicle can be immobilized in various positions, but the device complexity and ease of operation deteriorate due to the need to handle and position multiple different components
Solution Approach 1:
The stabilizer device incorporates an adjustable support surface that can be positioned at multiple heights and angles, allowing a single device to perform the function previously requiring multiple different-sized wedges or shims. The support surface can be adjusted to contact the vehicle body at different positions and orientations, providing universal applicability for stabilizing vehicles in various accident positions.
Solution Approach 2:
The stabilizer device features adjustable and movable components, including a support surface that can be repositioned and angled dynamically to adapt to different vehicle positions and rescue scenarios. This dynamic adjustability replaces the static, fixed-size wedges with a flexible system that can accommodate various stabilization needs.
2Adaptability or versatility
If multiple wedges or shims of different sizes are used, then various vehicle heights can be accommodated, but the ease of operation worsens due to the need for operators to manually position and adjust each component
Solution Approach 1:
The stabilizer device incorporates adjustable and movable components, including a support surface that can be repositioned and angled dynamically to adapt to different vehicle positions and rescue scenarios. This dynamic adjustability replaces the static, fixed-size wedges with a flexible system that can accommodate various stabilization needs.
3Reliability
If the vehicle is partially or completely overturned and stabilizer devices are used, then the vehicle can be immobilized, but the need for re-stabilization increases when the vehicle position changes, worsening the time efficiency
Solution Approach 1:
The stabilizer device features adjustable and movable components, including a support surface that can be repositioned and angled dynamically to adapt to different vehicle positions and rescue scenarios. This dynamic adjustability replaces the static, fixed-size wedges with a flexible system that can accommodate various stabilization needs.
4Reliability
If struts are used that protrude from the vehicle area, then the vehicle can be stabilized, but the ease of operation worsens by hindering rescue manoeuvres
Solution Approach 1:
The stabilizer device is designed with a compact structure where the support surface can be positioned close to the vehicle body without requiring long protruding struts. The device segments the stabilization function into a localized application point, reducing the spatial intrusion into the rescue zone while maintaining effective stabilization.
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
Facilitates efficient and secure immobilization of vehicles in various positions, reducing the need for frequent re-stabilization and enhancing rescue operations by allowing automatic adjustment to new vehicle heights and providing a stable platform for occupant removal.
Implementation Method 1
