Trampoline Support Structure Multi-Layer Tubular Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trampoline support structures suffer from inadequate structural strength, leading to bending, separation, or fracturing during use and transportation, and lack effective anchoring to prevent loosening of components under stress.
Innovation Solution
A trampoline support structure comprising a manifold with integrated longitudinal and transverse installation portions, a first annular tube, a mesh encircled tube, and a support tube, where the second annular tube is anchored on the first annular tube, and the mesh encircled tube is anchored on the manifold, forming a multi-layer tubular structure to enhance stability and prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional support structures are used with simple tube connections, then the device complexity is low, but the structural strength is insufficient leading to bending and fracturing
Solution Approach 1:
The patent implements a nested tubular structure where the first annular tube is inserted into the second annular tube, and the support tube is inserted into the first annular tube. This nesting arrangement creates multiple layers of structural support that work together to prevent bending and fracturing, while the insertion-based connection avoids complex welding or fastening operations.
Solution Approach 2:
The support structure is divided into multiple independent tubular components (manifold, first annular tube, second annular tube, support tube) that can be manufactured separately and then assembled through insertion. This segmentation allows each component to be optimized for its specific function while maintaining overall structural strength through their hierarchical arrangement.
2Reliability
If screw fastening is used to anchor the encircled mesh support rack, then the ease of manufacture is improved, but the reliability deteriorates due to loosening under stress
Solution Approach 1:
The mesh encircled tube is anchored by inserting it through the manifold's longitudinal installation portion and securing it within the nested tubular structure. This insertion-based anchoring eliminates the need for screws or other fasteners that could loosen under stress, while the nested structure provides inherent mechanical retention through friction and geometric interlocking.
Solution Approach 2:
The manifold serves as an intermediary component that provides a dedicated installation hole and longitudinal installation portion for anchoring the mesh encircled tube. This intermediary structure facilitates reliable anchoring through the insertion mechanism while simplifying the overall assembly process by providing pre-configured mounting features.
3Strength
If frame tubes are merely supported by transverse tubes without passing through, then the ease of operation is maintained, but the structural strength deteriorates causing easy bending under vibration
Solution Approach 1:
The patent implements a nested arrangement where the first annular tube is inserted into the second annular tube, and the support tube is inserted into the first annular tube. This nesting creates a multi-layered structural system where each tube provides support to the others, significantly enhancing anti-bending strength while the simple insertion mechanism maintains ease of assembly.
Solution Approach 2:
The support structure functions as a composite system where multiple tubular components work together to provide structural strength. The nested arrangement of different tubes creates a composite structure that leverages the strength of each individual tube while providing mutual support, effectively preventing bending under vibration and operational loads.

AI summary
A trampoline support structure includes a manifold, a first annular tube, a mesh encircled tube, a second annular tube and a support tube. The manifold includes a longitudinal installation portion, a transverse installation portion and an installation hole located on the transverse installation portion. The first annular tube includes a first assembly section inserted into the transverse installation portion and an anchor hole located on the first assembly section. The mesh encircled tube includes an anchor section inserted into the installation hole, the anchor hole and the longitudinal installation portion. The second annular tube includes a second assembly section inserted into the first assembly section. The anchor section, the longitudinal installation portion and the support tube form a multi-layer structure, thus can solve the problem of inadequate structural strength occurred to the conventional techniques.
