Foldable Cross Hinge Structure for Compact Storage and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shape of the cross makes it difficult to transport and store, as it is not easily collapsible for relocation.
Innovation Solution
A collapsible cross device with pivotably connected walls that can transform from a cross shape to a rectangular shape, allowing for compact storage and transport, utilizing a central frame member and hinge mechanisms for easy conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cross is made with a traditional fixed shape, then it maintains structural integrity and symbolic form, but it becomes difficult to transport and store
Solution Approach 1:
The cross is divided into multiple separable walls (first wall, second wall, third wall, fourth wall) that can be detached from the base. This segmentation allows the cross to be disassembled into smaller components for easy storage and transport, while still maintaining the complete cross structure when assembled.
Solution Approach 2:
The cross transitions from a static fixed structure to a dynamic reconfigurable structure. The walls are designed to be movable and detachable, allowing the cross to change between its displayed cross shape and a compact stored configuration, providing adaptability for different situations.
2Volume of moving object
If the cross is made collapsible for easy storage, then it improves transportability, but it may compromise the structural integrity
Solution Approach 1:
By segmenting the cross into separate walls that can be stored independently or reconfigured, the overall storage volume is reduced. Each wall maintains its structural integrity as a separate component, and the base provides a strong foundation when the cross is assembled for display.
Solution Approach 2:
The cross structure changes its physical parameters between two states: when assembled, it occupies a larger volume with full cross dimensions for display; when disassembled, it occupies minimal storage volume. The material properties and connection mechanisms are designed to maintain strength in both configurations.

Function Achieved in This Case
Enables convenient storage and transportation of the cross by allowing it to be folded into a compact rectangular shape from its extended cross form, maintaining structural integrity with rigid materials like metal or plastic.
Implementation Method 1

AI summary
A cross device may include a bottom wall, a first sidewall being pivotably connected to the bottom wall, a second sidewall being pivotably connected to the bottom wall, a third sidewall being pivotably connected to the bottom wall, a fourth sidewall being pivotably connected to the bottom wall, and a top wall being pivotably connected to the first sidewall. The cross device may be movable between a first position in the form of a cross and a second position in the form of a rectangle.
