Foldable glider chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glider chairs lack a compact and efficient design for easy storage and transportation, as they do not effectively transition between expanded and collapsed positions without compromising structural stability or ease of use.
Innovation Solution
A foldable glider chair design featuring a base and gliding seat frame pivotally connected, with over-center pivot linkages and strategically positioned leg and seat supports, allowing for a smooth transition between expanded and collapsed positions while maintaining structural integrity and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the glider chair is designed to be foldable for compact storage and transportation, then storage efficiency and ease of transport are improved, but structural stability and reliability may deteriorate
Solution Approach 1:
The glider chair is divided into multiple segments including the base, gliding seat frame, and pivot linkages that can fold relative to each other. This segmentation allows the chair to collapse into a compact configuration for storage while maintaining structural integrity when expanded through the interlocking pivot connections.
Solution Approach 2:
The chair employs dynamic pivot linkages and over-center mechanisms that allow smooth transition between expanded and collapsed states. The over-center pivot design provides mechanical stability in both positions while enabling easy folding, resolving the contradiction between structural reliability and compact storage capability.
2Ease of operation
If the glider chair uses over-center pivot linkages for smooth transition between positions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The over-center pivot linkage creates a dynamic mechanical advantage that provides smooth, controlled transition between expanded and collapsed positions. The geometry of the linkage naturally guides the folding motion while providing mechanical stability, achieving ease of operation without requiring complex control systems.
Solution Approach 2:
The over-center pivot mechanism is self-actuating through the user's natural folding motion. The mechanical geometry of the linkage automatically provides the smooth transition and locking action without requiring additional actuators, sensors, or control systems, thereby maintaining relatively simple device complexity.

AI summary
A foldable glider chair has a base and gliding seat frame pivotally connected to the base to allow relative movement of the gliding seat frame relative to the base in a reciprocating fashion in a direction parallel to the width edges of the seat. The base and gliding seat frame are foldable in tandem.
