Trampoline Tensioning Element with Triangular Retaining Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampoline tensioning systems either require full cable replacement upon damage or lack the ability to simultaneously fasten multiple cable ends, limiting adjustable tensioning options for varying user weights and jumping characteristics.
Innovation Solution
A tensioning element with a triangular arrangement of at least three retaining elements allows for adjustable cable routing and simultaneous fastening of multiple cable ends, enabling variable tensioning without tools and enhancing user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single elastic cable is used to tension the jumping mat, then the tensioning is simple, but the entire cable must be replaced if it tears
Solution Approach 1:
The elastic cable is divided into multiple segments that can be independently attached to the tensioning element. Each cable segment can be separately replaced without affecting the entire cable system, resolving the contradiction between simple tensioning and ease of repair.
2Ease of operation
If hook-shaped tensioning elements with two receiving sections are used, then the tensioning is simple and the jumping mat is automatically centered, but only one elastic ring can be fastened at a time
Solution Approach 1:
The tensioning element is designed with multiple retaining elements that can simultaneously hold multiple elastic rings and cable segments. This multi-functional design allows the same tensioning element to accommodate various cable configurations for different user weights and jumping characteristics while maintaining ease of operation.
3Adaptability or versatility
If the elastic cable is guided in different sizes of loops, then the tensioning can be adjusted for different body weights, but the cable routing becomes complex
Solution Approach 1:
The cable routing is simplified by segmenting the cable path into distinct loops that can be independently configured around the retaining elements. This allows tensioning adjustment for different body weights without complex routing, as each cable segment can be separately positioned around the appropriate retaining elements.

AI summary
The invention relates to a tensioning element (1) for tensioning a jumping mat (15) on a frame (16) of a trampoline (19) with the aid of an elastic cable (18), wherein the tensioning element (1) comprises a basic body (2) with a plurality of retaining elements (3a-3c) for retaining the elastic cable (18). In order to allow variable adjustment of the mat tensioning, the invention proposes to provide a plurality of retaining elements (3a-3c) on the same side of the basic body (2), and therefore the elastic cable can be positioned optionally around one or more of the retaining elements (3a-3c).
