Trampoline Packaging System Vacuum Bag Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampoline packaging methods are inefficient in minimizing the size of the packaged product and preventing rattling during transport, as they do not effectively utilize vacuum sealing and structural arrangement to secure components.
Innovation Solution
A trampoline packaging system comprising a box with strategically arranged flaps and leg stacks, combined with partially evacuated vacuum bags to enclose the trampoline components, including an enclosure net and spring covers, which reduces the overall size and secures the contents by using the vacuum bags as packaging material and a spring-like mechanism to prevent rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional packaging methods are used for trampolines, then the packaging is simple and easy to manufacture, but the packaging size cannot be minimized and rattling occurs during transport
Solution Approach 1:
The packaging system divides the trampoline into separate components (frame, mat, springs, enclosure net) and packages them individually in vacuum-sealed bags. This segmentation allows each component to be compacted to its minimum volume while preventing rattling, resolving the contradiction between small packaging size and system complexity.
Solution Approach 2:
The patent employs vacuum sealing technology to remove air from packaging bags containing trampoline components. The vacuum process compresses the components to eliminate void spaces, dramatically reducing packaging volume. The vacuum bags also act as cushioning materials to prevent rattling during transport, simultaneously achieving compact packaging and vibration prevention.
2Volume of moving object
If vacuum sealing is used to reduce packaging size, then the packaging volume is minimized, but the complexity of the packaging system increases
Solution Approach 1:
The packaging system nests vacuum-sealed bags containing trampoline components inside a larger outer packaging box. The vacuum bags are arranged to fit efficiently within the box volume, with multiple bags nested or positioned to maximize space utilization. This nesting approach minimizes the total volume while keeping the vacuum sealing process relatively simple.
Solution Approach 2:
The vacuum bags are designed to be self-sealing and self-cushioning. Once vacuum-sealed, the bags maintain their compact form and protective function without requiring additional active mechanisms or complex packaging structures. The vacuum bags serve their own protective and space-saving functions, reducing the need for supplementary packaging systems.
3Reliability
If components are loosely packaged to prevent damage, then the components are protected, but the packaging size increases and rattling occurs
Solution Approach 1:
The vacuum sealing process removes air from around the trampoline components, creating a tight seal that prevents movement and rattling. The vacuum environment also compresses the components to eliminate void spaces that would cause shifting during transport. This simultaneously provides excellent protection and minimizes packaging volume.
Solution Approach 2:
The packaging uses flexible vacuum-sealed bags made of stretchable material that conforms to the shape of the trampoline components. These flexible bags provide cushioning and protection while adapting to the compacted dimensions of the components, preventing rattling without requiring additional rigid packaging structures that would increase volume.

Function Achieved in This Case
The system effectively reduces the size of the packaged trampoline, secures components, and prevents rattling by utilizing vacuum-sealed bags to conform to the contents, minimizing the need for additional packaging material and enhancing transport efficiency.
Implementation Method 1
The first vacuum bag is at least partially evacuated and the second vacuum bag is also partially evacuated
