Combination Ramp System with Overlap Groove Connecting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ramp systems for sports face structural issues when assembling overlap joint bridges between ramps, as increased size leads to depression or breakage under user weight due to inadequate support.
Innovation Solution
A combination ramp system comprising a first and second ramp, a connecting assembly with overlap grooves and tenon members, and a shelf board assembly with a supporting stem that includes stationary and lifting rods for enhanced structural support and stability.

Engineering Contradiction Analysis
1Length of stationary object
If the size of the overlap joint bridge is increased to allow greater distance between ramps, then the ramps can be positioned farther apart, but the bridge will easily deform or break under user weight
Solution Approach 1:
The connecting assembly is divided into multiple components: first and second connecting members with overlap grooves, tenon members for insertion, and a shelf board assembly with supporting stems. This segmentation allows each component to perform a specific function while working together to support the bridge structure over longer distances without deformation or breakage
Solution Approach 2:
The overlap grooves and tenon members are strategically positioned at specific locations on the connecting members to provide localized reinforcement. The shelf board assembly with supporting stems is placed at critical points to distribute weight and prevent deformation, allowing the bridge to span greater distances while maintaining structural integrity at key stress points
2Strength
If the overlap joint bridge is made more robust to prevent deformation under weight, then structural integrity is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The connecting assembly is divided into modular components (connecting members with grooves, tenon members, shelf board assembly with supporting stems) that can be manufactured separately and assembled together. This segmentation reduces the complexity of manufacturing each individual component while achieving the required overall structural integrity through their coordinated arrangement
Solution Approach 2:
The tenon members are inserted into the overlap grooves, creating a nested structure where one component fits within another. The shelf board assembly with supporting stems is nested within the connecting members. This nesting approach provides structural reinforcement without requiring additional external support structures, maintaining relative simplicity while improving strength
