Foldable multifunction chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable chairs are limited in providing varied comfortable postures and functional usage, particularly unable to offer an office desk-like posture for tasks that require mouse and keyboard control, and lack configurations for compact transportation.
Innovation Solution
A foldable multifunction chair with a selectively adjustable deployment mechanism, including a base, user body support, and locking mechanism, allowing the user body support to be adjusted to multiple angles and positions, combined with a collapsible seat and arm assembly for versatile use and compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chair is designed with fixed structure, then manufacturing is simple, but adaptability and versatility are limited
Solution Approach 1:
The chair employs multiple adjustable components including an adjustable backrest with multiple locking positions, adjustable armrests with height and angle adjustment, and an adjustable seat pan inclination. These dynamic elements allow the chair to adapt to various user needs and postures, transforming a static structure into a versatile multifunctional seating solution.
Solution Approach 2:
The chair is divided into multiple independent adjustable segments: the backrest can be adjusted separately, the armrests can be adjusted independently in height and angle, and the seat pan can be inclined independently. This segmentation allows each component to be optimized for specific functions while maintaining overall structural manageability.
2Adaptability or versatility
If the chair provides multiple adjustable positions, then comfort and functionality are improved, but the folding and transport convenience is reduced
Solution Approach 1:
The chair features a collapsible frame structure with telescopic legs and a foldable backrest that can be quickly transformed from an expanded seating position to a compact folded position. The dynamic design allows smooth transitions between multiple states without requiring complex assembly or disassembly operations.
Solution Approach 2:
When folded, the chair components nest within each other - the seat pan folds into the backrest structure, the armrests collapse into compact positions, and the legs telescope into each other. This nesting arrangement minimizes the folded volume while maintaining all adjustment capabilities when deployed.
3Ease of operation
If the chair is designed for compact transport, then portability is improved, but the functionality for desk work is reduced
Solution Approach 1:
The chair incorporates adjustable armrests that can be positioned at multiple heights and angles, allowing users to configure the chair for proper ergonomic positioning during desk work. The adjustable backrest and seat pan inclination provide additional ergonomic support for prolonged sitting, transforming a compact transport design into a functional office chair when deployed.
Solution Approach 2:
The chair is designed to serve multiple functions: it can be used as a standard seating chair, a reclining chair, or configured for desk work with the adjustable armrests and backrest. The same compact structure that enables easy transport also supports these diverse functions through its adjustable components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to adopt over ten distinctive positions for rest, leisure, and desk work, providing comfort and functionality similar to a traditional office chair while maintaining compactness for easy transport.
Implementation Method 1
a selectively adjustable chair deployment mechanism cooperatively coupled to the base and the user body support, the chair deployment mechanism being configured for selectively adjusting the user body support to a desired angle relative to the base
Implementation Method 2
a locking mechanism configured for angularly locking the user body support to the desired angle relative to the base

AI summary
A foldable multifunction chair including a base for contacting a support surface; a user body support having a support front surface for contacting a user body, the user body support being adjustably pivotably mounted to the base along a transversal axis; a selectively adjustable chair deployment mechanism cooperatively coupled to the base and the user body support, the chair deployment mechanism being configured for selectively adjusting the user body support to a desired angle relative to the base; and a locking mechanism configured for angularly locking the user body support to the desired angle relative to the base. The chair may be used, e.g., as a backrest with an accessory support positioned in front thereof for work, or as a seated workstation wherein the accessory support is positioned adjacent a rear surface of the user body support in a deployed position, and the collapsible seat in a deployed position.
