Modular Trampoline Frame Joints for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampolines have large package volumes due to structural restrictions, making them inconvenient to transport and assemble.
Innovation Solution
A trampoline design featuring quick-assembly joints with obround insertion columns and protrusions/recesses for secure connection, along with detachable frames and pipes, allowing for easy disassembly and reassembly to reduce package volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional trampoline structures are used, then structural stability is maintained, but package volume becomes large and transportation becomes inconvenient
Solution Approach 1:
The trampoline structure is divided into multiple detachable segments including frame sections, leg pipes with cross pipes, and modular support structures. Each segment can be independently packaged, significantly reducing the overall package volume for transportation while allowing for straightforward reassembly at the destination through the quick-assembly joint system.
2Volume of moving object
If detachable connections are implemented, then package volume is reduced, but assembly time and complexity increase
Solution Approach 1:
Quick-assembly joints serve as intermediary components that facilitate rapid connection between detachable segments. These joints incorporate insertion columns with protrusion-recess engagement mechanisms and positioning sidewalls that guide alignment, enabling workers to assemble the trampoline structure quickly without requiring complex tools or procedures, thus minimizing assembly time despite the detachable nature of the connections.
3Ease of operation
If quick-assembly joints with multiple components are used, then assembly ease is improved, but device complexity increases
Solution Approach 1:
The quick-assembly joint design merges multiple functional elements into integrated components. The insertion column combines the connection function with built-in positioning features (protrusions and recesses), while the support flat surfaces and positioning sidewalls are integrated directly into the joint structure rather than being separate elements. This merging reduces the number of discrete parts and simplifies the overall device complexity while maintaining ease of assembly.

AI summary
A trampoline is provided, the trampoline including a trampoline frame and leg pipes for supporting the trampoline frame. Each leg pipe includes a cross pipe and two stand pipes, the two stand pipes being detachably connected to two ends of the cross pipe to form a U-shaped structure. An upper end of each stand pipe is detachably connected to the trampoline frame.
