Adjustable Tension Trampoline Frame for Spring Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trampolines experience reduced tautness over time due to spring deformation, requiring frequent spring replacement, and are difficult to move or store due to their size and bulkiness, necessitating an adjustable tension system and a foldable design.
Innovation Solution
A trampoline with an adjustable tension system that includes a first and second connecting member allowing for sliding movement to adjust the circumference of the frame assembly, thereby increasing or decreasing spring tension, and a foldable design with pivoting joints to facilitate easy folding and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trampoline uses a fixed frame assembly, then the structure is simple and stable, but the spring tension cannot be adjusted and the trampoline mat loses tautness over time
Solution Approach 1:
The frame assembly incorporates movable connecting members that can slide along the frame members to adjust the circumference of the frame assembly, thereby dynamically changing the tension in the springs. This allows the system to transition from a fixed structure to an adjustable one, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The invention changes the parameter of frame assembly circumference by moving connecting members to different positions. This parameter change directly affects the spring tension, allowing users to adjust the tautness of the trampoline mat without replacing springs, thus improving adaptability while maintaining reasonable structural complexity.
2Ease of operation
If the trampoline is made foldable for easy storage, then the ease of movement and storage improves, but the safety during folding deteriorates due to residual spring tension
Solution Approach 1:
Before folding the trampoline, the user must first reduce the spring tension by moving the connecting members to decrease the frame assembly circumference. This preliminary action of tension reduction eliminates the harmful spring tension that could cause injury during folding, while still allowing the foldable design to provide ease of storage.
3Reliability
If the spring tension is increased to improve tautness, then the trampoline mat provides better rebound, but the springs experience increased wear and deformation over time
Solution Approach 1:
Instead of permanently increasing spring tension, the invention allows users to adjust the frame assembly circumference parameter to optimize tension levels. This enables the system to maintain appropriate tension for good rebound while avoiding excessive tension that would accelerate spring deformation and reduce service life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable tension system allows for customizable tautness and compensates for spring deformation, while the foldable design enables safe and efficient movement and storage of the trampoline.
Implementation Method 1
The first connecting member is configured to slidably move in a first direction with respect to the second connecting member
Implementation Method 2
the first side and the second side are configured to pivot into a substantially perpendicular position with respect to the first and second base frame members

AI summary
A foldable or non-foldable trampoline includes a frame assembly that supports a resilient trampoline mat using a plurality of springs. The frame assembly includes an adjustable tension system that adjusts a dimension of the frame assembly. For a circular frame assembly, the adjustable tension system may increase the circumference of the frame assembly to increase a tension of the springs. The adjustable tension system may also decrease the circumference of the circular frame assembly to decrease a tension of the springs.
