Trampoline Mat Clip-and-Loop Attachment for Easier Tensioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bungee cords are difficult to use for achieving the required tension in trampoline jumping mats, especially for larger trampolines, due to the fiddly process of knotting and the challenge of applying adequate tension, which complicates assembly and maintenance.
Innovation Solution
A method and apparatus using a clip with a hook and aperture, combined with an elastic connector, where the elastic connector is passed through the aperture, around the hook and frame, and connected to the mat, allowing for adjustable tension by looping the connector multiple times between the frame and mat, and a fastener for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual bungee cords are used to attach the trampoline mat, then the assembly process becomes simpler and safer compared to traditional springs, but achieving the required tension in the jumping mat becomes extremely difficult
Solution Approach 1:
Multiple bungee cords are combined into a single integrated elastic connector that spans across multiple attachment points on the frame, allowing the connector to accumulate and distribute tension effectively while maintaining ease of assembly through a single-piece design
2Force
If each individual bungee cord is knotted to achieve adequate tension, then the required tension can be obtained, but the assembly process becomes extremely difficult and time-consuming
Solution Approach 1:
The elastic connector is divided into multiple functional segments or loops that can be independently adjusted and attached to different frame points, allowing tension to be distributed and achieved without requiring complex knotting of a single continuous cord
Solution Approach 2:
The elastic connector is pre-configured with loops and attachment points during manufacturing, so that during assembly the user simply needs to connect these pre-formed elements to the frame rather than performing complex knotting operations to achieve the required tension
3Force
If bungee cords are stretched to provide adequate tension for the jumping surface, then the required tension is achieved, but the process becomes extremely difficult even for mini trampolines
Solution Approach 1:
A rigid or semi-rigid guide structure or tool is introduced as an intermediary between the assembler and the elastic connector, providing mechanical advantage and proper alignment to facilitate stretching and attachment of the connector without requiring the assembler to directly handle and stretch the cord to full tension
