Pop-Up Container Frame for Height Stability and Easy Collapse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pop-up containers face limitations in maintaining strength and stability at greater heights and often have cumbersome designs with numerous parts, which can lead to ineffective assembly due to stress on the frame components after use.
Innovation Solution
A pop-up structure comprising three or more loops with resiliently deformable elongate members that pivotally attach to each other, allowing the framework to extend and collapse, providing structural stability and flexibility, and can be manufactured from lightweight materials like fiberglass, with optional support surfaces and a cover for secure storage and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If containers use horizontal hoops interconnected by flexible profiled rods with hinge pins, then the container can be extended and collapsed, but the container remains cumbersome with numerous parts and cannot extend to great heights
Solution Approach 1:
The patent combines multiple structural elements into integrated components. The spiral frame integrates the hoop structure with the supporting members into a unified continuous spiral form, eliminating the need for separate hinge pins and multiple connection points. This merging reduces the number of parts while maintaining the extendable and collapsible functionality through the continuous spiral geometry.
2Stability of the object's composition
If containers use spiral frames that are collapsible by rotation, then the container can be compacted and stored, but the container cannot maintain strength and stability at greater heights
Solution Approach 1:
The patent employs a dynamic spiral frame structure that can adapt its configuration. The spiral frame is designed to be rotatable, allowing it to transition between extended and collapsed states. This dynamic capability enables the frame to maintain strength at greater heights when extended while allowing compact storage when collapsed, resolving the contradiction between height stability and collapsibility.
3Volume of moving object
If containers are extended to greater heights, then the storage capacity increases, but the container cannot maintain strength and stability
Solution Approach 1:
The patent introduces a vertical spiral dimension to the frame structure. Instead of traditional horizontal hoops stacked vertically, the spiral frame rises vertically in a helical path. This dimensional change allows the container to achieve greater height and storage capacity while the spiral geometry inherently provides structural strength and stability through its self-supporting helical form.

Function Achieved in This Case
The framework maintains structural stability at varying heights, is lightweight yet strong, and facilitates easy assembly and disassembly, addressing the issues of strength, stability, and complexity in existing pop-up containers.
Implementation Method 1
a plurality of resiliently deformable elongate members extending between adjacent loops, the elongate members being pivotally attached to the loops
Implementation Method 2
