Reclining foldable chair and method of operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable chairs lack the ability to provide multiple seating positions, including both upright and reclined options, while maintaining portability and ease of storage.
Innovation Solution
A reclining foldable chair design featuring a collapsible frame, adjustable legs, and reclining assemblies that allow transition between upright and reclined positions, along with a seat cover that can be secured to the frame, enhancing comfort and reducing size for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chair is designed to be foldable for portability, then the chair can be compacted for storage and transport, but the chair loses the ability to provide multiple seating positions including reclined options
Solution Approach 1:
The chair is divided into separate functional modules: a collapsible support frame for portability, a separate seat cover with integrated reclining assembly for comfort, and independent leg assemblies for stability. This segmentation allows each component to be optimized for its specific function while maintaining overall versatility.
Solution Approach 2:
The chair incorporates dynamic elements including collapsible frame sections that can be folded for transport, adjustable legs that can be positioned at different angles, and a reclining assembly that allows the seat to transition between upright and reclined positions. These dynamic features enable the chair to adapt to different usage scenarios.
2Adaptability or versatility
If the chair provides multiple seating positions for comfort, then user comfort is improved, but the chair size increases reducing portability
Solution Approach 1:
The reclining assembly and adjustable components are nested within the seat cover structure, allowing them to fold or collapse into a compact form when not in use. The leg assemblies can be folded against the frame, and the entire chair can be collapsed to a minimal volume for storage and transport.
Solution Approach 2:
The chair uses dynamic mechanisms that allow components to be compacted when not needed and deployed when required. The collapsible frame sections, foldable legs, and reclining assembly all transition between compact and functional states, providing multiple seating positions without permanently increasing the chair's storage volume.
3Device complexity
If the chair is made compact for storage, then portability is improved, but the structural integrity may be compromised
Solution Approach 1:
The chair frame is segmented into multiple rigid sections connected by folding joints, allowing the structure to be compacted while maintaining strength in each individual section. The seat cover with integrated reclining assembly is separated from the support frame, allowing independent optimization of each component's structural properties.
Solution Approach 2:
The chair includes pre-positioned support elements and bracing structures that are built into the folded configuration. When the chair is collapsed for storage, these preliminary structural supports are already in place to maintain the integrity of the compact form, preventing damage during transport.

AI summary
A reclining foldable chair includes a support frame and a seat cover secured to the support frame. The support frame is configured to transition between a storage and use position and includes a first and second upright, a seat bottom support, a collapsible cross-brace, a seat back rest, and a reclining assembly configured to allow the chair to transition between upright and reclined positions. The reclining assembly includes a recline limiter and a pivoting link latch. The pivoting link latch includes a pivoting link and a moving link, wherein an overall length between opposite ends of the pivoting link and moving link is adjustable in order to transition the reclining foldable chair between the upright and reclined positions.
