Trampoline Enclosure Net with Interwoven Hem and Zipper Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampoline enclosures with netting do not adequately address the issue of user safety and visibility, as they often have dense fabrics that obstruct views and may pose entrapment risks due to small apertures.
Innovation Solution
A trampoline design featuring an enclosure net with a lower density fabric, small apertures for safety, and a securing cord system that interweaves with the trampoline bed hem openings, along with a resilient spring loop sleeve and zipper panel for easy access, suspended from enclosure poles and connected to a frame with bolt connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dense fabric is used for enclosure netting, then enclosure strength is improved, but visibility is reduced and finger entrapment risk increases
Solution Approach 1:
The patent applies porous materials by using netting with specifically sized apertures that are large enough to prevent finger entrapment while maintaining enclosure integrity. The netting fabric is designed with controlled porosity to balance safety requirements with structural strength, allowing the enclosure to remain robust while eliminating the harmful entrapment effect.
2Strength
If dense fabric is used for enclosure netting, then enclosure strength is improved, but visibility is reduced
Solution Approach 1:
The patent uses porous netting material with optimized aperture sizes that allow light transmission for visibility while maintaining sufficient fabric density for structural strength. The porous structure enables visual monitoring of the trampoline area without compromising the enclosure's ability to contain users safely.
3Object-affected harmful factors
If small apertures are used in netting, then finger entrapment is prevented, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by specifying precise aperture size parameters in the netting fabric that meet safety standards while remaining compatible with standard manufacturing processes. By defining specific dimensional parameters for the apertures, the patent enables mass production of safety-compliant netting without requiring complex or specialized manufacturing techniques.
