Folding Chair with Wheel Assembly and Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional folding chairs face challenges with mobility and stability, particularly in outdoor environments, due to their lightweight construction and susceptibility to tipping over or being blown away by wind, making them cumbersome to transport and unsafe to use.
Innovation Solution
A folding chair design featuring a frame assembly with pivotally connected scissors-like cross-shaped structures, telescopic upright supports, and wheel assemblies with quick-release mechanisms and coupling mechanisms for connecting multiple chairs, enhancing mobility and stability through compactness and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional folding chairs are designed to be lightweight for easy carrying and storage, then portability is improved, but mobility and stability deteriorate due to susceptibility to tipping and being blown away by wind
Solution Approach 1:
The patent combines multiple folding chairs into a connected assembly through coupling mechanisms, creating a unified stable structure that resists tipping and wind forces while maintaining the lightweight advantage of individual chair components
Solution Approach 2:
The patent incorporates wheel assemblies with quick-release mechanisms that are pre-installed on the chairs, allowing users to quickly attach wheels before transport and remove them when stability is needed, proactively addressing the mobility-stability tradeoff
2Ease of operation
If traditional folding chairs are designed to be lightweight for easy carrying, then ease of operation is improved, but mobility deteriorates due to cumbersome transport over long distances
Solution Approach 1:
The wheel assemblies are pre-installed on the chair frames, so users only need to attach them before transport rather than carrying the entire chair, enabling quick transition from carrying mode to rolling mode for efficient long-distance movement
Solution Approach 2:
The quick-release mechanism allows dynamic switching between carrying state (wheels removed) and rolling state (wheels attached), optimizing the transport method based on distance and terrain requirements
3Ease of manufacture
If folding chairs are designed with simple structures for ease of manufacture, then ease of manufacture is improved, but stability deteriorates in windy outdoor conditions
Solution Approach 1:
Multiple simple folding chairs are combined into a connected assembly through coupling mechanisms, creating a larger stable structure that resists wind forces while each individual chair component remains simple to manufacture
Solution Approach 2:
Wheel assemblies and coupling mechanisms are pre-installed on the chair frames during manufacturing, adding stability features without requiring complex assembly steps by the end user
