Vehicle Clamping System Using Hooks and Pegs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping systems for motor vehicles on lifting platforms are bulky, pose safety risks due to protruding parts, and require modification of standard lifts, making them inefficient and hazardous for operators.
Innovation Solution
A clamping system featuring hooks and a horizontal peg that securely engage with the lifting support's hole, utilizing a vertical clamping mechanism such as a clamping screw or threaded rod to tighten the vehicle to the lifting plate, ensuring a compact, safe, and standard-compatible fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clamping elements are used to secure the vehicle body to the lifting platform, then the vehicle is firmly fixed, but the clamping elements are bulky and have protruding bars that can injure operators
Solution Approach 1:
The clamping system is divided into separate functional components: hooks that engage with the lifting platform, a horizontal peg that passes through the vehicle body, and vertical clamping means. This segmentation allows each component to be optimized independently, with the hooks and peg designed to be compact and non-protruding while still providing reliable fixation.
Solution Approach 2:
Instead of using external clamps that protrude from the vehicle sides, the invention inverts the approach by using hooks that engage from below the vehicle body, with a horizontal peg passing through the vehicle's lifting support hole. This internal engagement method eliminates external protruding parts while maintaining fixation reliability.
2Reliability
If additional telescopic arms are added to the lift to maintain vehicle stability, then the vehicle can be secured against tilting, but the lift structure is modified and space requirements increase
Solution Approach 1:
The horizontal peg serves multiple functions: it provides lateral positioning of the vehicle body, prevents tilting movements, and works in conjunction with the vertical clamping means to achieve complete fixation. This multi-functionality eliminates the need for separate anti-tilting devices like additional telescopic arms.
Solution Approach 2:
The anti-tilting function is merged into the primary clamping mechanism by using the horizontal peg that passes through the vehicle body. This integration combines positioning and anti-tilting functions into a single element, avoiding the need for separate structural modifications to the lift.
3Force
If bulky clamping elements with protruding bars are used, then strong clamping force is achieved, but the device size increases and safety hazards are created
Solution Approach 1:
The clamping force is generated internally by the vertical clamping means that act on the horizontal peg from below, rather than using external bulky clamps. This inverted approach allows strong clamping force to be achieved with a compact device that fits within the vehicle's underbody space.
Solution Approach 2:
The clamping force is applied in the vertical dimension through the vertical clamping means, while the horizontal peg provides lateral constraint. This dimensional separation allows effective clamping without requiring bulky horizontal protrusions, reducing the device's external volume while maintaining clamping effectiveness.
