Vehicle Ramp Triangular Support Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle ramp devices face challenges in increasing support rigidity while minimizing weight, as concentrated load on central support portions leads to flexure and require thicker plates, which increase weight.
Innovation Solution
The ramp design features support members extending along the entire length of the ramp body, forming triangular shapes that decrease in height, dispersing load and allowing for thinner plates, thus enhancing rigidity without increasing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If support members are provided only at the extension direction central portion of the ramp body, then the ramp body can be supported at the center, but load is concentrated at the central portion and flexure occurs in the front and rear end regions
Solution Approach 1:
The support members are divided into multiple segments along the extension direction of the ramp body, with at least one support member positioned in the front end region and at least one in the rear end region. This segmentation distributes the support function across different locations, preventing load concentration and reducing flexure while maintaining overall stability.
2Strength
If the plate thickness of the ramp body is increased to raise rigidity and suppress flexure, then the ramp body becomes more rigid, but the weight of the ramp increases commensurately
Solution Approach 1:
Instead of uniformly increasing plate thickness throughout the ramp body, the invention segments the support function by placing support members at specific locations (front end and rear end regions). This allows the ramp body to maintain adequate rigidity through strategic support placement rather than universal thickening, thereby reducing overall weight.
Solution Approach 2:
The support members are strategically positioned at the front end and rear end regions where flexure is most likely to occur. This local quality approach provides enhanced support precisely where needed, allowing the rest of the ramp body to use thinner plates, thus optimizing the balance between rigidity and weight.

AI summary
A ramp includes: a ramp body having a ramp face; and support members that, when the ramp body is used, are each disposed at a respective width direction end of the ramp body so as to run along an extension direction of the ramp body including at an extension direction central portion of the ramp body, the width direction being orthogonal to the extension direction of the ramp body, the support members respectively forming triangular shapes having heights that decrease on progression from one end portion side to another end portion side in the extension direction of the ramp body in side view, and a lower end of each of the support members making contact with a ground contact surface so as to support the ramp body from a lower side.
