Multi-Purpose Folding Chair with Segmented Plates for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding chairs are heavy, large, and inconvenient for transportation due to their inability to reduce in size, occupying significant storage space.
Innovation Solution
A multi-purpose folding chair design featuring foldable components such as supporting side plates, seat plate, kneeling plate, and armrests, with reinforcement structures and inclined kneeling plate to distribute stress evenly, allowing for compact storage and ease of transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the chair is designed with a rigid structure to maintain stability and support, then the structural strength is improved, but the weight and size increase, making it inconvenient for transportation and storage
Solution Approach 1:
The chair is divided into multiple independent plates (supporting side plates, connecting plates, seat plate, kneeling plate, armrest plates, back plate) that can be folded relative to each other. This segmentation allows the chair to maintain structural strength when assembled while reducing to a compact size for storage and transportation.
Solution Approach 2:
The chair employs pivot connections between plates that enable dynamic transformation between an expanded usable state and a compact folded state. The pivot connections maintain structural integrity during use while allowing size reduction for storage.
2Strength
If the chair is designed with a rigid structure to maintain stability and support, then the structural strength is improved, but the volume increases, occupying significant storage space
Solution Approach 1:
The chair is divided into multiple independent plates (supporting side plates, connecting plates, seat plate, kneeling plate, armrest plates, back plate) that can be folded relative to each other. This segmentation allows the chair to maintain structural strength when assembled while reducing to a compact size for storage and transportation.
Solution Approach 2:
When folded, the plates are arranged in a nested configuration where connecting plates, seat plate, and kneeling plate are positioned between the supporting side plates, creating a compact folded state that minimizes storage volume while preserving structural integrity.
3Strength
If reinforcement structures are added to maintain structural integrity during folding, then the strength is improved, but the device complexity increases
Solution Approach 1:
Reinforcement structures (such as reinforcement ribs or strengthened regions) are added only at specific critical locations on the plates where stress concentrates during folding and unfolding, rather than throughout the entire structure. This maintains structural integrity while minimizing the increase in device complexity.

AI summary
A multi-purpose folding chair is provided. The chair includes two supporting side plates arranged in a corresponding configuration, two connecting plates, a seat plate, and a kneeling plate. Each of the two connecting plates is formed with a first folding line. The two connecting plates are arranged between the two supporting side plates and pivotally connected to the two supporting side plates, such that the two connecting plates are foldable in a flat manner along the first folding line. The seat plate is formed with a second folding line and is arranged between the two supporting side plates. Two sides of the seat plate respectively and pivotally connected to the two supporting side plates. The seat plate is foldable in a flat manner through the second folding line. The kneeling plate is formed with a third folding line and is arranged between the two supporting side plates.
