Permeable Trampoline Pad Airflow and Pad Slap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-ground trampolines often suffer from inadequate ventilation, leading to air compression issues that reduce the bounce height and safety, as traditional protective pads prevent air escape, causing 'pad slap' and decreased performance.
Innovation Solution
The incorporation of a permeable protective pad with orifices allows air to pass through, combining a foam member with a mesh covering to enhance airflow and maintain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional protective pad is used in an in-ground trampoline, then safety protection is provided, but air cannot escape during compression resulting in pad slap and reduced bounce performance
Solution Approach 1:
The protective pad incorporates a permeable material with numerous small holes distributed throughout its structure, allowing air to pass through during compression while the pad remains intact and provides safety protection. This resolves the contradiction by enabling air escape (improving bounce performance) while maintaining the protective function.
2Object-affected harmful factors
If the trampoline is positioned at ground level to reduce injury risk, then safety is improved, but air venting becomes problematic due to sub-surface placement
Solution Approach 1:
The permeable protective pad serves as a built-in air venting solution that is integrated into the trampoline structure. The porous material allows air to escape through the pad itself during compression, eliminating the need for separate venting mechanisms and simplifying the overall device while maintaining ground-level safety positioning.
3Stability of the object's composition
If the protective pad prevents air escape, then pad stability is maintained, but compressed air forces the pad up and down causing noise and distraction
Solution Approach 1:
The permeable material allows air to pass through the pad in a controlled manner during compression and expansion cycles. This prevents the buildup of compressed air that would otherwise force the pad to move violently, reducing noise and distraction while the pad maintains its structural integrity and stability through the distributed hole pattern.

Function Achieved in This Case
This solution improves bounce quality and safety by allowing trapped air to escape, reducing 'pad slap' and maintaining protection, while ensuring the trampoline operates effectively at ground level.
Implementation Method 1
The protective pad may incorporate a permeable material or configuration to allow for the passage of air through the protective pad

AI summary
An in-ground trampoline including a frame, trampoline mat, a plurality of springs and a protective pad. The protective pad incorporates a permeable material to allow for the passage of air through the protective pad. The in-ground trampoline system may also include a retaining wall which may comprise self-locking panels. In some embodiments, the self-locking panels may be attached to the frame of the in-ground trampoline.
