Hanging collapsible chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture is structurally rigid, making it difficult to minimize its size when not in use, leading to space management issues as it occupies significant room space unless disposed of or relocated.
Innovation Solution
A hanging collapsible chair design featuring a rack and a collapsible chair with pivotally connected supporting frames and soft material connecting units, allowing the chair to be fully extended for use and immediately collapse when not in use due to gravity and weak connecting units, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the furniture is structurally rigid, then the strength and stability are improved, but the size cannot be minimized when not in use
Solution Approach 1:
The chair employs dynamic structural elements including pivotally connected supporting frames that can rotate between extended and collapsed positions, and soft material connecting units that flexibly join components. This allows the chair to transition from a rigid extended state during use to a collapsed state for storage, resolving the contradiction between structural strength and storage volume.
Solution Approach 2:
The chair is divided into multiple independent supporting frames (first, second, third, and fourth supporting frames) that can move relative to each other through pivotal connections. This segmentation allows individual frames to collapse independently, enabling the entire chair to be minimized in size while maintaining structural integrity when extended.
2Ease of operation
If the connecting units are made by soft materials, then the ease of collapse is improved, but the strength to sustain weight is reduced
Solution Approach 1:
The soft material connecting units are designed to be flexible enough to allow easy collapse when the chair is not in use, yet strong enough to sustain the chair's weight during use. The soft material properties enable the connecting units to dynamically adapt between these two functional states without requiring additional mechanical fastening mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the chair to be minimized in size when not in use by collapsing, addressing space management challenges through a functional design that utilizes gravity and soft material connections for efficient storage.
Implementation Method 1
When the chair is in use or in its extended configuration, it has to be hung on the rack with the supporting unit, so the collapsible chair can be fully extended due to the existence of gravity, and the rack and the supporting unit collectively sustain the weight of the entire chair.
Implementation Method 2
when the chair is disposed on the ground, the chair collapses immediately because the connecting units are too weak to sustain the weight of the chair

AI summary
A hanging collapsible chair set may include a rack and a collapsible chair, wherein the collapsible chair can be hung on the rack. The collapsible chair has a main body, a seating unit, a plurality of supporting frames and a plurality of connecting units. In one embodiment, each supporting frame is curved with two ends, and each end is pivotally connected with the main body of the collapsible chair. The seating unit is also pivotally connected with the main body. The connecting units are configured to flexibly connect the seating unit with one of the supporting frames, two of the supporting frames, and one of the supporting frames with the main body. In one embodiment, the connecting unit can be a string.
