Frameless Trampoline Spring Tensioning Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trampolines rely on rigid metal frames for maintaining tension, which are bulky and heavy, and springless trampolines lack the spring back and bounce performance associated with typical trampolines.
Innovation Solution
A floatable trampoline design that uses springs to couple the jump surface directly to a floatable support without a rigid frame, utilizing apron and mat connectors with triangular rings and straps to distribute tension uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid metal frame is used to maintain tension on the trampoline mat, then the mat can be kept taught and provide proper support, but the apparatus becomes bulky and heavy
Solution Approach 1:
The patent removes the rigid metal frame from the trampoline structure entirely, extracting only the essential function of tension maintenance. The frameless design eliminates the heavy structural component while preserving the mat tensioning capability through alternative means (springs and tensioning mechanisms integrated into the mat edges).
Solution Approach 2:
The patent replaces the rigid mechanical frame structure with a flexible spring-based tensioning system. Instead of using a rigid metal framework to maintain mat tension, the invention employs springs and elastic elements that provide the necessary tension forces without requiring a heavy structural frame.
2Device complexity
If springs are removed to create a springless trampoline, then the structure can be simplified, but the bounce performance and spring back action are severely sacrificed
Solution Approach 1:
The patent removes traditional rigid frame structures while extracting and redistributing the spring elements throughout the mat structure. Individual springs are attached at multiple points along the mat edges rather than relying on a central frame, simplifying the overall structure while maintaining bounce performance through distributed spring action.
Solution Approach 2:
The patent divides the spring support system into multiple individual spring units distributed along the mat edges rather than using a single integrated frame structure. This segmentation allows each spring to independently provide bounce action while collectively maintaining mat tension, achieving both structural simplicity and reliable bounce performance.
3Stability of the object's composition
If a rigid frame is used to secure the mat, then proper tension can be maintained, but the overall structure becomes less adaptable and more difficult to transport
Solution Approach 1:
The patent transitions from a static rigid frame structure to a dynamic spring-based system that can adapt to different usage conditions. The springs provide flexible tensioning that adjusts naturally to mat deformation and user weight, enabling the structure to accommodate various configurations and transport requirements while maintaining stable mat tension during use.

Function Achieved in This Case
The solution provides a lightweight, floatable trampoline with improved bounce performance by eliminating the need for a rigid frame while maintaining even tension across the jump surface, enhancing user experience and reducing structural weight.
Implementation Method 1
springs, wherein at least one spring is attached to at least one first connector and at least one second connector so as to couple the mat to the apron
