Trampoline Rope Hook Structure for Symmetrical Cord Ring Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for trampolines, particularly those using elastic rope rings, suffer from asymmetrical stress due to uneven elastic properties along the rope ring, leading to premature wear and adverse vibration behavior during use.
Innovation Solution
A rope hook design with a fixing device that centers and secures the connection points within receiving spaces, preventing lateral displacement and ensuring symmetrical loading of the rope ring, thereby maintaining consistent elastic properties across all tension sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connection point of the rope ring is located in one of the pull sections, then the rope ring can be easily assembled, but the elastic properties become asymmetrical leading to premature wear and poor vibration behavior
Solution Approach 1:
The receiving space is divided into distinct zones: a first region that receives the rope ring end sections and a second region that receives the connection point. This segmentation allows the connection point to be positioned separately from the pull sections, preventing asymmetrical stress while maintaining assembly simplicity.
Solution Approach 2:
The invention introduces a spatial dimension solution by creating a receiving space with differentiated regions along the rope ring's path. The connection point is accommodated in a second region that is spatially distinct from the first region where the rope ring ends are received, effectively moving the connection point out of the asymmetric stress zone of the pull sections.
2Ease of manufacture
If the rope ring has different elastic properties in different sections, then assembly is simplified, but asymmetrical stress occurs causing premature wear
Solution Approach 1:
The receiving space is designed with different local qualities: the first region is configured to receive and support the rope ring end sections, while the second region is specifically designed to receive and accommodate the connection point. This local differentiation ensures that the connection point does not experience the asymmetric stresses present in the pull sections, thereby preventing premature wear while maintaining assembly simplicity.
3Adaptability or versatility
If the connection point is not fixed against lateral displacement, then the rope ring has freedom of movement, but asymmetrical loading occurs affecting vibration behavior
Solution Approach 1:
The receiving space is segmented into functional regions that provide both guidance and fixation. The first region receives the rope ring ends allowing some movement freedom, while the second region specifically receives the connection point and provides lateral displacement prevention through the structured configuration of the receiving space, ensuring symmetrical loading and optimal vibration behavior.

Function Achieved in This Case
The solution enhances the service life of the rope ring and improves the vibration behavior of the trampoline by distributing stress evenly, reducing wear and maintaining optimal performance.
Implementation Method 1
The fastening system for attaching or clamping a swing mat to the frame of a trampoline is crucial for the durability and in particular the vibration behavior of the trampoline during use
