Foldable Seating Structure for Compact Storage and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating furniture is not compact or stable, requiring significant effort to transform between storage and seating forms, and often lacks comfort and stability.
Innovation Solution
A foldable seating furniture design featuring a support structure with angled leg panels, a rigid plate, and a cover that extends to cover the support structure, providing stability and comfort while allowing for easy storage and transport, with additional features like adjustable backrests, lighting, and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the seating furniture is made foldable for compact storage, then the storage volume is reduced, but the stability and load-bearing capacity deteriorate
Solution Approach 1:
The support structure is divided into multiple leg panels that can be folded together, allowing the chair to be disassembled into compact segments for storage while maintaining structural integrity when assembled. The rigid plate is also segmented with recesses that accommodate the leg panels, enabling stable configuration when unfolded.
Solution Approach 2:
The leg panels are designed to be dynamically foldable between extended (stable seating) and retracted (compact storage) positions. This dynamic capability allows the same structure to provide both stability during use and compactness for storage, resolving the contradiction between these two states.
2Weight of moving object
If the support structure is made lightweight for easy transport, then the ease of operation is improved, but the load-bearing capacity deteriorates
Solution Approach 1:
The support structure combines lightweight materials with strategic reinforcement through the rigid plate design. The rigid plate with recesses creates a composite structural system that provides high load-bearing capacity relative to the overall weight, enabling easy transport while maintaining strength.
Solution Approach 2:
The rigid plate is segmented with recesses that accommodate the leg panels, creating an efficient load distribution system. This segmentation allows the structure to bear significant weight through optimized geometry rather than adding material mass, maintaining strength while keeping weight low.
3Shape
If the cover extends fully to cover the support structure, then the aesthetic appearance is improved, but the manufacturing complexity increases
Solution Approach 1:
The cover is designed as a single piece that extends along the leg panels, creating a seamless aesthetic appearance. This unified cover design simplifies manufacturing by eliminating the need for multiple separate components, while still achieving full coverage of the support structure for enhanced visual appeal.

AI summary
The invention relates to a seating furniture which comprises a seating surface (132), a supporting structure (160, 161, 162, 163), and a cover (134). The supporting structure (160, 161, 162, 163) is designed to support the seating surface (132) with respect to a base (131) and to keep the supporting structure at a distance from said base. The supporting structure (160, 161, 162, 163) is designed to be foldable such that said structure can be releasably fixed in an unfolded state. The cover (134) is designed to at least partly cover the supporting structure (160, 161, 162, 163), said cover (134) extending outward from an edge (135) of the seating surface (132) in a direction away from the seating surface (132).
