Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanging chairs are non-foldable, leading to large packaging sizes and high transportation costs, limiting their popularity due to inflexibility and bulkiness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the hanging chair is designed with a fixed shape, then the structural stability is improved, but the packaging volume increases and transportation cost increases
Solution Approach 1:
The hanging chair is divided into multiple independent components: frame, base, and support rods. These components can be folded relative to each other through folding structures, allowing the overall volume to be reduced for packaging and transportation while maintaining structural integrity when assembled.
Solution Approach 2:
The hanging chair incorporates folding structures that enable dynamic transformation between unfolded (use) state and folded (storage/transport) state. The base and support rods can rotate relative to the frame through hinges and connection members, allowing volume reduction without compromising structural stability during use.
2Ease of manufacture
If the hanging chair is made non-foldable, then the manufacturing simplicity is improved, but the ease of transportation deteriorates
Solution Approach 1:
The chair structure is segmented into modular components connected by folding mechanisms. This segmentation allows each component to be independently manufactured using simple processes, while the overall assembly gains foldability for easy transportation and storage.
Solution Approach 2:
The folding structure allows components to nest within each other when folded. The base and support rods can be positioned inside or alongside the frame structure, reducing the overall transportation volume while maintaining manufacturing simplicity through standardized connection components.
3Strength
If the hanging chair uses rigid connection structures, then the structural strength is improved, but the foldability deteriorates
Solution Approach 1:
The connection structures are designed as dynamic folding joints rather than rigid fixed connections. Hinges and rotation mechanisms allow the components to move relative to each other while maintaining structural strength when in the unfolded position, enabling both foldability and structural integrity.
Solution Approach 2:
The folding structures are pre-designed with connection members (hinges, rods, flexible connections) that maintain structural strength in the unfolded state. These pre-configured connection elements ensure that when the chair is assembled and unfolded, the structural strength is sufficient to support use, while the foldable nature allows for compact storage.
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
The foldable design significantly reduces the chair's volume when folded, making it more convenient for storage, transportation, and packaging, thereby lowering costs and enhancing market appeal.
Implementation Method 1
the other end of the stud may pass through the first connection member to be connected with the nut through thread cooperation
Implementation Method 2
the second connection member is capable of being rotated relative to the first connection member

AI summary
A foldable hanging chair includes a frame; a base, foldably installed at a bottom of the frame; at least one support rod, foldably installed at one side of the frame; and flexible connection members, connecting the frame, the base, and the support rod together; wherein in an unfolded state, both the support rod and the base are at a certain angle to the frame, and the frame, the base, the support rod, and the flexible connection members enclose an accommodation space; and in a folded state, both the support rod and the base are close to one side of the frame. As both the base and the support rod are foldably installed at the frame, and at the same time, the flexible connection members connect the frame, the base, and the support rod together, the folding of the foldable hanging chair is not affected.
