Levelling Ramp Assembly With Integrated Wheel Chock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing levelling ramp assemblies for caravans face challenges such as difficulty in positioning wheels horizontally, instability due to the need for chocks, and the risk of losing chocks, which can render the ramp unusable.
Innovation Solution
A levelling ramp assembly comprising a ramp with attachment elements and a chock with corresponding attachment elements that engage to hold the ramp and chock together, providing stability and ease of use, and including adjustable plates to increase ramp height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a chock is used to brace a caravan wheel on a ramp, then stability is improved and unwanted movement is prevented, but the device complexity increases and the risk of losing the chock increases
Solution Approach 1:
The chock and ramp are merged into a single integrated unit through attachment elements. The chock assembly includes a chock body with attachment elements that connect to corresponding attachment elements on the ramp, creating a unified stable platform that eliminates the need for separate chocking operations and prevents loss of components.
Solution Approach 2:
The integrated chock-ramp assembly can be segmented for storage and transport. The attachment elements allow the chock to be connected or disconnected from the ramp as needed, providing both stability during use and ease of storage when not in use.
2Ease of manufacture
If the ramp has a consistent sloping gradient, then the ramp is simple in design and easy to manufacture, but the tyre cannot be positioned horizontally which causes operational difficulty
Solution Approach 1:
The ramp incorporates adjustable features that allow the surface to be modified from a consistent slope to include a horizontal section. This dynamic adjustment capability enables the ramp to adapt to different operational requirements, allowing tyres to be positioned horizontally while maintaining ease of manufacture through standardized components.
Solution Approach 2:
The ramp design incorporates a localized horizontal section at the top surface while maintaining the sloped approach. This local quality change allows tyres to be positioned horizontally for stable parking without requiring the entire ramp to be complex or difficult to manufacture.
3Adaptability or versatility
If two ramps are used to level a dual axle caravan, then the caravan can be levelled, but the device complexity increases and storage becomes more difficult
Solution Approach 1:
The integrated chock-ramp assembly is designed to be universal and can be used for both single axle and dual axle caravans. The attachment elements and adjustable features allow a single unit to perform the function of multiple separate ramps, reducing device complexity and storage requirements while maintaining adaptability to different caravan configurations.
