Trampoline Ball Socket Joint for Noise-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampolines, especially larger ones, face difficulties in assembly due to cumbersome pin-and-tab connections that require two people and can lead to noise and damage during use and transport, with foldable segments needing support to prevent damage.
Innovation Solution
A trampoline design featuring a support system with a play-free angle joint that uses a ball socket and ball pivot for easy assembly and disassembly, allowing single-person operation and preventing noise, with interchangeable components for repair and transport protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pins and tabs are used to connect supports to frame segments, then the connection can be disassembled, but the assembly requires two people and produces noise during use
Solution Approach 1:
The patent replaces the traditional pin-and-tab connection with a spherical ball joint connection. The ball element with spherical surface enables smooth insertion into the socket without requiring precise alignment, allowing single-person assembly while eliminating play between components. The curved spherical geometry naturally guides the ball into the socket during assembly and provides a stable, noise-free connection during trampoline use.
2Ease of operation
If play is allowed between pins and tabs for easy insertion, then assembly is easier, but noise is produced during trampoline use
Solution Approach 1:
The spherical ball joint design allows the ball to be easily inserted into the socket with a light tap without requiring play or gaps. The spherical geometry provides self-centering during insertion while the tight fit between ball and socket eliminates play during operation, preventing noise generation during trampoline use.
3Ease of operation
If tabs protrude from feet for connection, then connection is possible, but tabs are easily damaged during transport
Solution Approach 1:
The patent inverts the traditional connection approach by attaching the ball element to the foot instead of having tabs protrude from the foot. The spherical ball is more resistant to damage during transport compared to protruding tabs, while the socket remains on the support structure for connection.
4Reliability
If multiple pins are hooked into tabs simultaneously, then connection is achieved, but assembly becomes cumbersome requiring coordination
Solution Approach 1:
The spherical ball joint replaces multiple pins that need to be coordinated into multiple tabs. The single spherical ball can be easily inserted into the socket without requiring precise coordination, significantly simplifying the assembly process while maintaining a secure connection.

AI summary
The invention relates to a trampoline, comprising a frame construction and a jumping mat mounted on said frame construction. A support (5) connects elements of the frame construction. The support (5) is rotatably mounted on a first segment of the frame construction. The support (5) of the frame construction is fixed to a second segment by means of an angle joint (7).
