Foldable Cardboard Archway Structure for Space-Saving Play
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional play structures, such as doll's houses and Wendy houses, are often space-consuming and inconvenient for storage when not in use.
Innovation Solution
A foldable cardboard archway structure that can be easily erected and disassembled, using corrugated cardboard or similar materials, which can be compactly stored by folding into a small space, and features a single piece design with hinged panels and a horizontal lintel for stability and decoration options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional play structures like doll's houses and Wendy houses are used, then children can engage in imaginative play, but the structures consume excessive storage space when not in use
Solution Approach 1:
The play structure is divided into multiple collapsible panels that can be segmented and folded together. The structure comprises a series of connected panels that form walls, roof, and supporting elements, which can be collapsed into a compact configuration for storage while maintaining structural integrity during play.
Solution Approach 2:
The play structure transitions from a static, fixed form to a dynamic, collapsible form. The panels are designed with hinges and connection mechanisms that allow the structure to be easily assembled and disassembled, transforming from a spacious play environment to a compact storage configuration.
2Volume of stationary object
If foldable cardboard structures are used to save storage space, then the structure can be compactly stored, but the structural strength and stability may be compromised
Solution Approach 1:
The structure utilizes corrugated cardboard as the primary material, which combines fluted inner layers with flat outer layers to create a composite structure with high strength-to-weight ratio. The corrugation pattern provides inherent structural reinforcement, allowing the material to maintain strength while being lightweight and foldable.
Solution Approach 2:
The design incorporates curved and angled panel configurations that distribute structural loads more effectively. The roof panels are positioned at angles to provide structural support, and the overall geometry is designed to maximize strength while maintaining the ability to collapse flat for storage.
3Ease of manufacture
If a single piece of folded material is used to construct the archway, then manufacturing and assembly are simplified, but the structural complexity of folding and erection increases
Solution Approach 1:
The single piece of corrugated cardboard is pre-cut and pre-folded into distinct panel segments that correspond to different structural elements (walls, roof, supports). Each panel is designed with specific fold lines and connection features that guide the assembly process, reducing the complexity of erection while maintaining manufacturing efficiency.

AI summary
An arch type play structure may be formed of a single large sheet of e.g. cardboard, which can be folded to flat form for storage, or which may be folded in such a way that parts of it form a box-like structure containing other parts of it. The arch may be decorated e.g. to represent a fireplace (5) or gate.
