Collapsible Hanging Chair Frame for Ergonomic Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanging chairs fail to simultaneously provide comfort, ergonomics, safety, ease of transportation, and space-efficient storage, often requiring users to adopt unhealthy positions due to rigid structures and difficult folding mechanisms.
Innovation Solution
A collapsible hanging chair design featuring three ring-shaped frame elements connected by releasable and pivoting connections, allowing for a triangular cross-section frame that can be easily assembled and disassembled, with a motorized suspension system for ergonomic support and space-saving functionality, suitable for use in virtual reality simulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid wicker walls or stiffening elements are used to provide structural support, then the chair maintains its shape and provides support, but the user's spine must conform to the rigid shape which does not correspond to individual anatomy, reducing ergonomics and comfort
Solution Approach 1:
The patent replaces rigid wicker walls with a dynamic suspension system comprising multiple flexible elements (strings, ropes, or elastic elements) that can adapt their configuration based on user weight and position. This dynamic system allows the chair to conform to individual user anatomy while maintaining structural support, resolving the contradiction between strength and ergonomics.
Solution Approach 2:
The patent employs adjustable parameters in the suspension system, including the number, length, and elasticity of suspension elements, which can be modified to change the chair's support characteristics. This allows optimization of both structural support and ergonomic comfort for different users and usage scenarios.
2Strength
If rigid wicker walls are used to provide structural support, then the chair maintains its shape, but the chair becomes difficult to transport and requires large storage space
Solution Approach 1:
The patent divides the chair into separable components: a collapsible frame structure and suspension elements that can be detached. This segmentation allows the chair to be disassembled into compact parts for easy transport and storage, while each component maintains its structural integrity when assembled.
Solution Approach 2:
The patent employs a collapsible frame with movable joints that can transition between an expanded usable configuration and a compact storage configuration. This dynamic structure reduces the volume occupied during storage and transport while maintaining full structural support when in use.
3Volume of moving object
If stiffening elements are folded parallel to each other to reduce storage space, then the chair takes up less space, but the stiffening elements remain rigid and do not improve ergonomics
Solution Approach 1:
The patent replaces traditional rigid stiffening elements with flexible suspension elements (strings, ropes, or elastic members) that naturally conform to user anatomy. These flexible elements provide necessary structural support while adapting to individual user shapes, improving ergonomics without requiring parallel folding for storage.
Solution Approach 2:
The patent employs a collapsible frame with movable joints that transitions between expanded and compact configurations. Combined with flexible suspension elements, this dynamic system achieves both compact storage and ergonomic comfort, eliminating the need for rigid parallel folding.
4Volume of moving object
If hanging chairs without stiffening are used to fit into small spaces, then storage space is reduced, but users must adopt unhealthy hunched positions
Solution Approach 1:
The patent divides the support function into two separate components: a collapsible frame for spatial efficiency and flexible suspension elements for ergonomic support. This segmentation allows the frame to be compact for storage while the suspension elements maintain proper user posture during use.
Solution Approach 2:
The patent employs a collapsible frame with movable joints that provides structural definition while allowing flexibility. Combined with elastic suspension elements, this dynamic system offers both compact storage capability and ergonomic support, preventing hunched positions while reducing storage volume.
5Ease of operation
If releasable connections are used to enable easy assembly and disassembly, then ease of transportation is improved, but the connection mechanism becomes more complex
Solution Approach 1:
The patent employs self-locking or self-aligning connection mechanisms that automatically engage or disengage without requiring complex tools or procedures. These self-service features simplify the assembly and disassembly process while minimizing the complexity of the connection mechanisms themselves.
Solution Approach 2:
The patent extracts the connection function into separate, modular components that can be easily attached and detached. This extraction allows for simple, tool-free connection mechanisms that prioritize ease of assembly while maintaining structural integrity when connected.
