Trampoline Enclosure Buttonhole Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trampoline enclosure attachment methods are time-consuming, prone to gaps between the flexible wall and the trampoline mat, and can lead to injuries, especially for smaller jumpers, as they may slip through or collide with metal springs.
Innovation Solution
The trampoline enclosure features buttonholes around the bottom edge of the flexible wall designed to accommodate spring attachment features like D-rings, providing a quick and secure attachment method that minimizes gaps and protects jumpers from springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible wall is attached to the trampoline mat using a rope loosely woven about the perimeter, then the attachment method is simple to implement, but gaps exist between the rebounding surface and the bottom of the flexible wall leading to safety hazards
Solution Approach 1:
The flexible wall is divided into multiple segments with buttonholes distributed along its bottom edge. Each buttonhole engages with a separate spring attachment feature, creating multiple discrete attachment points that collectively eliminate gaps while maintaining ease of installation.
Solution Approach 2:
Buttonholes are introduced as intermediary elements between the flexible wall and the spring attachment features. These buttonholes provide a standardized interface that simplifies attachment while ensuring close contact between the flexible wall and the trampoline mat, eliminating hazardous gaps.
2Reliability
If manual weaving of the flexible wall and rebound surface with a cord is used, then the attachment can be made securely, but the process is tedious and time consuming
Solution Approach 1:
Buttonholes are pre-formed in the flexible wall during manufacturing, and spring attachment features are pre-positioned on the trampoline mat. This preliminary preparation eliminates the need for time-consuming on-site weaving or knotting, allowing for rapid attachment while maintaining secure connection.
Solution Approach 2:
The buttonhole and spring attachment feature design enables the flexible wall to attach to the trampoline mat without requiring external tools or complex manual operations. The spring attachment features can be directly inserted through the buttonholes, allowing the system to self-assemble quickly and securely.
3Device complexity
If gaps exist between the rebounding surface and the flexible wall, then the attachment structure remains simple, but injuries can occur as limbs slide into the gaps or jumpers fall off
Solution Approach 1:
Multiple buttonholes are distributed along the bottom edge of the flexible wall at spaced intervals. This segmentation creates multiple contact points that collectively eliminate gaps between the flexible wall and the trampoline mat, preventing limbs from sliding in and reducing injury risk without requiring a complex overall structure.
Solution Approach 2:
The buttonhole attachment features are concentrated at the critical location where the flexible wall meets the trampoline mat perimeter. This localized application of the buttonhole mechanism specifically addresses the gap formation problem at the most hazardous area while keeping the rest of the structure simple.
4Device complexity
If the springs are exposed, then the trampoline structure remains simple and inexpensive, but jumpers can fall against the metal springs causing injuries
Solution Approach 1:
Buttonholes serve as intermediary attachment points that position the flexible wall in close contact with the trampoline mat, creating a protective barrier between jumpers and the metal springs. This intermediary mechanism eliminates the need for additional spring guards or complex protective structures.

AI summary
A way to attach a trampoline enclosure to a trampoline frame is described. This process involving constructing the enclosure with a buttonhole at or near its bottom edge. This buttonhole is designed to receive a spring attachment feature located on the rebounding mat of the trampoline structure. Generally, this spring attachment feature will be the D-ring (or V-ring) that is used to attach the rebounding mat to the springs. The D-ring will pass through the buttonhole and, when connected to a corresponding spring, will securely attach the trampoline enclosure to the trampoline.
