Vehicle Support Leg With Inclined Guide Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for vehicles, such as caravans, face challenges in achieving high support height, minimizing installation height, and ensuring ease of operation and stability, while also being cost-effective and payload-efficient, due to limitations in design and the need for multiple support points.
Innovation Solution
A support device with a guide track arrangement where the lower point is closer to the fixed pivot of the side strut, allowing for a large support height and minimal overall height, combined with a hydraulic cylinder for convenient operation and a three-point support system for enhanced stability and payload efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional support devices with hand crank and spindle are used, then the device can be operated manually, but the operation is very tedious and inconvenient
Solution Approach 1:
The patent replaces the manual hand crank and spindle mechanism with a hydraulic cylinder system. The hydraulic cylinder uses fluid pressure to automatically extend and retract the support leg, eliminating the need for manual cranking operations. This substitution of mechanical systems with hydraulic systems directly resolves the contradiction by making operation convenient while reducing time loss.
2Length of moving object
If telescopic cylinders are used to achieve high lifting height, then the support height is increased, but the overall height becomes too great requiring folding during transport
Solution Approach 1:
The patent changes the arrangement of the guide track from a vertical orientation to an inclined orientation relative to the vehicle floor. This dimensional change allows the support leg to achieve high support height through the inclined guide track while the overall installation height remains compact. The support leg extends along the inclined guide track rather than vertically, enabling high lifting capability without increasing the vertical installation footprint.
3Stability of the object's composition
If multiple support points (seven points) are used to support the vehicle, then the vehicle is well-supported, but the weight increases reducing payload capacity
Solution Approach 1:
The patent extracts and eliminates redundant support points from the conventional seven-point support system, reducing to a three-point support system. By removing unnecessary support components and simplifying the support architecture, the system achieves adequate vehicle support with significantly reduced weight, thereby increasing payload capacity while maintaining stability.
4Length of moving object
If the support leg is designed for high support height, then the support capability is improved, but the installation height increases causing damage risk during driving
Solution Approach 1:
The patent employs an inclined guide track arrangement that allows the support leg to achieve high support height along the incline while maintaining a compact vertical installation height. This dimensional reorientation enables the support leg to extend far enough to provide high support capability without protruding excessively upward, thereby minimizing the risk of damage during driving while preserving support performance.
