Foldable Cabinet with Double Pivot Connections for Compact Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional storage cabinets are bulky, time-consuming to assemble, and cumbersome to transport due to their fixed structure, making them inefficient for shipping and storage.
Innovation Solution
A foldable cabinet design featuring double pivot connections that allow side walls to rotate inward, reducing the cabinet's volume and simplifying assembly and transportation by enabling a compact folded configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fixed-size cabinet structure is used, then structural stability is maintained, but assembly time increases and transportation becomes cumbersome
Solution Approach 1:
The cabinet structure is divided into multiple panels (front, back, side walls) that can be independently assembled and folded. Each panel is connected through pivot mechanisms rather than permanent fixed joints, allowing the cabinet to be segmented into manageable sections for easier assembly and disassembly while maintaining structural integrity when assembled.
Solution Approach 2:
The cabinet employs dynamic pivot connections instead of static fixed joints. The double pivot connections allow panels to rotate and fold relative to each other, transforming the cabinet from a rigid fixed structure into a dynamic system that can be easily assembled, disassembled, and folded for storage or transportation without requiring complex assembly procedures.
2Volume of moving object
If fixed-size cabinet structure is used, then structural stability is maintained, but shipping space and costs increase
Solution Approach 1:
The cabinet panels are designed to fold inward and nest against each other when collapsed, with side walls folding toward the center and panels stacking in a compact configuration. This nesting arrangement dramatically reduces the volume occupied during shipping and storage while the interlocking pivot connections and panel designs maintain structural stability when the cabinet is assembled and in use.
3Volume of moving object
If foldable side walls with double pivot connections are used, then shipping space is reduced, but device complexity increases
Solution Approach 1:
The double pivot connections merge multiple functions into a single mechanical element. Each pivot connection simultaneously provides rotational movement for folding, structural support when assembled, and alignment guidance for panels. This consolidation of functions reduces the need for separate complex mechanisms while achieving the desired folded volume reduction.
Solution Approach 2:
The dynamic pivot connections enable the cabinet to transition between assembled and folded states through simple rotational movements. The pivots are designed to provide stability in the assembled position while allowing easy folding when needed, creating a system that achieves compact folded volume without requiring overly complex locking or support mechanisms.

AI summary
A cabinet may include a front wall attached to a front proximal supporting leg and a front distal supporting leg, a back wall attached to a back proximal supporting leg and a back distal supporting leg, a first foldable side wall attached to the front proximal supporting leg and the back proximal supporting leg, and a second foldable side wall attached to the front distal supporting leg and back distal supporting leg. The first foldable wall may include a first panel connected to a second panel by at least a first double pivot connection, and the second foldable wall may include a third panel connected to a fourth panel by at least a second double pivot connection.
