Folding Chair with Rotating Elements for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chairs are bulky and non-foldable, making them difficult to store and transport, especially in outdoor environments.
Innovation Solution
A folding chair design featuring interconnected rods and rotating elements that allow the chair to pivot and fold, reducing its size for easier storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chair is made lightweight and easy to move, then it is easy to move the chair to a predetermined place or stack up such chairs not in use, but the chair cannot be folded and thus is bulky and of a fixed shape
Solution Approach 1:
The chair is divided into multiple separable components including front legs, rear legs, seat, and backrest, connected through folding joints. This segmentation allows each component to be independently positioned during folding, enabling the chair to collapse into a compact configuration that occupies minimal space while maintaining ease of movement when assembled.
Solution Approach 2:
The chair incorporates dynamic folding joints and rotating elements that allow the structure to transition between a stable unfolded state for use and a compact folded state for storage. The front legs can rotate relative to the seat, and the rear legs can fold relative to the backrest, creating a dynamically adaptable structure that reduces volume when not in use.
2Ease of operation
If the chair is made lightweight and easy to move, then it is easy to move the chair to a predetermined place or stack up such chairs not in use, but the chair cannot be folded and thus is bulky
Solution Approach 1:
The chair employs dynamic folding mechanisms including rotating joints at the front legs and folding joints at the rear legs, enabling the structure to transform from a fixed rectangular shape during use to a compact linear configuration for transport. This dynamic capability allows the chair to adapt its shape based on operational requirements.
Solution Approach 2:
The folding mechanism allows components to nest within each other during the folding process. The front legs fold underneath the seat, while the rear legs collapse along the backrest, creating a nested configuration that minimizes the overall bounding box of the folded chair, significantly reducing the space required for transport.
3Ease of operation
If the chair is made lightweight and easy to move, then it is easy to move the chair to a predetermined place or stack up such chairs not in use, but the chair cannot be folded and thus takes up more space for storage
Solution Approach 1:
By segmenting the chair into modular components connected by folding joints, the design enables complete collapse of the structure into a compact bundle. The front legs, rear legs, seat, and backrest can all be folded together, creating a storage configuration that occupies minimal space compared to non-foldable chairs that must be stacked in their full-size form.
Solution Approach 2:
The dynamic folding joints allow the chair to transition smoothly between its full-size operational state and a compact storage state. The rotating elements and folding mechanisms enable all components to converge into a small volume, dramatically reducing the storage space required while maintaining ease of operation when deployed.
