Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-roll structures for vehicles are cumbersome, heavy, and difficult to handle, occupying valuable space, while foldable solutions often fail to provide adequate structural stability and may damage tires due to uneven weight distribution.
Innovation Solution
A foldable anti-roll structure comprising two pivotable support elements with a junction element allows for adjustable angles, providing a stable and compact solution that can be easily stored, featuring a wedge-like profile for effective tire blocking without damaging the tire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-roll structures are produced in single blocks to ensure structural stability, then strength and reliability are improved, but weight and volume increase making them difficult to handle and store
Solution Approach 1:
The anti-roll structure is divided into multiple support elements (first support element, second support element, third support element) that can be pivoted relative to each other. This segmentation allows the structure to maintain strength when deployed while reducing weight and volume for storage, directly resolving the contradiction between structural stability and weight.
2Reliability
If anti-roll structures are produced in single blocks to ensure structural stability, then reliability is improved, but volume increases making storage difficult
Solution Approach 1:
The structure is segmented into multiple pivoting support elements that can be collapsed into a compact configuration for storage. When deployed, these elements form a stable anti-roll structure, thus resolving the contradiction between maintaining structural stability and reducing storage volume.
Solution Approach 2:
The anti-roll structure transitions from a static single-block design to a dynamic multi-element structure that can pivot between deployed and stored configurations. This dynamic capability allows the structure to maintain stability when needed while minimizing volume during storage.
3Volume of stationary object
If foldable anti-roll structures are used to reduce volume, then ease of storage is improved, but structural stability deteriorates
Solution Approach 1:
The foldable structure is segmented into multiple support elements with specific geometric relationships (inclined surfaces, lying surfaces) that maintain structural stability when deployed. The segmentation allows for compact folding while preserving the mechanical integrity needed for stability.
Solution Approach 2:
The support elements are designed with composite geometric features combining inclined surfaces, lying surfaces, and junction elements that work together to distribute loads and maintain structural stability even in a foldable configuration.
4Volume of stationary object
If foldable anti-roll structures are used to reduce volume, then ease of storage is improved, but ease of operation deteriorates due to handling complexity
Solution Approach 1:
The segmented design with pivot joints allows the structure to be collapsed into a compact, manageable form for easy storage and retrieval. The modular nature simplifies handling compared to a large monolithic block, while the pivot mechanism ensures quick deployment.

AI summary
An anti-roll structure suitable for blocking rolling objects. The anti-roll structure comprises a first support element and a second support element, which consist in, respectively, a lying surface adapted to be placed on a bearing plane and, parallel to the said bearing plane, and a support surface, opposite to the lying surface and inclined with respect to the said lying surface. A junction element is positioned so that it lies on a plane perpendicular to the lying surface and supporting surface. The first and second support element can be placed at a predefined angle with respect to each other by means of the junction element.
