Trampoline Frame with Angled Ropes for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trampolines have a disadvantageous edge area formed by springs between the jumping mat and the frame, which cannot be used for exercises and poses a safety risk, requiring additional design efforts for covering the springs.
Innovation Solution
The trampoline design features a frame construction with a first frame enclosing the jumping bed and a second frame below it, using ropes with elastic elements that are angled out of the plane of the jumping bed, eliminating the need for a cover and allowing full use of the area by shifting the elastic elements out of the jumping area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If springs are arranged horizontally between the jumping mat and the frame, then the jumping mat can be supported on the frame, but the edge area formed by the springs cannot be used for exercises and poses a safety risk
Solution Approach 1:
The patent applies dimensionality change by moving the springs from a horizontal arrangement (in the plane of the jumping mat) to a vertical arrangement (perpendicular to the jumping mat plane). The springs are positioned between a first frame above the jumping mat and a second frame below it, allowing the jumping mat to be fully utilized while eliminating safety hazards at the edges.
2Reliability
If a cover is applied to the springs as a protective measure, then safety is improved, but additional design effort and complexity are required
Solution Approach 1:
The patent extracts the springs from the jumping mat plane and positions them vertically between the first and second frames. This extraction eliminates the need for protective covers entirely, as the springs are completely separated from the user area, thereby improving safety without adding design complexity.
3Force
If elastic elements are positioned in the plane of the jumping mat, then the jumping mat can be supported, but the area delimited by the frame cannot be fully used for exercises
Solution Approach 1:
The patent resolves this contradiction by repositioning the elastic elements (springs) from the horizontal plane to the vertical dimension. The springs extend perpendicular to the jumping mat between the first and second frames, providing full elastic support while allowing the entire area within the first frame to be used for exercises without obstruction.
4Device complexity
If the frame construction uses a single horizontal frame, then the structure is simple, but the edge area with springs reduces usable space
Solution Approach 1:
The patent applies segmentation by dividing the frame structure into two separate frames: a first frame positioned above the jumping mat and a second frame positioned below it. This segmentation allows the elastic elements to be distributed vertically between the frames, eliminating the need for edge-area springs and maximizing the usable exercise area.
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
This design enhances safety by eliminating the risk of contact with elastic elements, provides a compact trampoline, and optimizes elastic force transmission for better jumping properties, allowing the entire area to be used for exercises without the need for additional design efforts.
Implementation Method 1
The cables are attached to the second frame by means of elastic elements arranged between the first and second frames
Implementation Method 2
the elastic elements are formed by springs. In particular, the springs are formed by tension springs
