Folding rocking chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rocking chairs are bulky and difficult to store due to their fixed structure, requiring large spaces for transportation and indoor placement.
Innovation Solution
A folding rocking chair design featuring pivotally connected rods and multilink parts that allow the chair to be folded from a three-dimensional unfolded state to a compact state, utilizing pivot connecting parts, multilink parts, and fixing rods to facilitate easy handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rocking chair uses a fixed structure with arc bottom rod and upper seat fixed to each other, then the rocking chair can provide stable rocking functionality, but it becomes bulky and requires large space for transportation and storage
Solution Approach 1:
The rocking chair is divided into multiple separable components including front rod assembly, rear rod assembly, seat assembly, and arc bottom rod assembly. These segments can be disconnected and folded relative to each other, allowing the chair to transition from an expanded functional state to a compact storage state, thereby reducing occupied space while maintaining rocking functionality when assembled
Solution Approach 2:
The rocking chair incorporates dynamic folding joints and pivot connections that allow the structure to transition between fixed and folded states. The front rod, rear rod, and seat assembly can rotate and fold relative to the arc bottom rod, enabling the chair to adapt its volume based on whether it is in use or storage mode
2Stability of the object's composition
If the rocking chair uses a fixed structure, then it provides stable sitting experience, but it is not easily stored due to bulk when placed indoors
Solution Approach 1:
The chair structure is segmented into modular assemblies that can be easily disconnected and folded. The front rod assembly, rear rod assembly, and seat assembly are separate components that can be collapsed against the arc bottom rod, transforming the stable fixed structure into a compact folded configuration for convenient indoor storage
Solution Approach 2:
The design incorporates dynamic folding mechanisms with pivot joints that allow the chair to transition from a stable fixed configuration during use to a compact folded configuration for storage. The folding action maintains structural integrity while dramatically reducing the space required for indoor placement
