Rocking chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rocking chairs with detachable rocking members result in a scattered and messy structure during assembly and disassembly, making them difficult to unfold and fold.
Innovation Solution
A rocking chair design featuring a bundle folding structure with interrupted rocking members, where two supporting portions with interconnected components allow for easy unfolding and folding, avoiding the detaching operation of rocking members, and incorporating telescopic and rotatable elements for stability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rocking member is made detachable for easy assembly and disassembly, then the ease of operation is improved, but the structure becomes scattered and messy, increasing device complexity
Solution Approach 1:
The patent integrates the rocking member into the seat frame by providing a rocking member receiving cavity in the seat frame and a rocking member extending from the seat, eliminating the need for separate detachable connections. This merging of components resolves the structural scattering issue while maintaining ease of assembly through the integrated design.
Solution Approach 2:
The rocking member is divided into multiple segments (first rocking member and second rocking member) that can rotate relative to each other and to the seat frame. This segmentation allows the rocking function to be achieved through rotational movement of integrated components rather than through detachable assembly, reducing structural complexity.
2Volume of moving object
If the rocking chair is designed with multiple detachable components for compact storage, then the volume is reduced, but the ease of operation deteriorates due to difficult assembly and disassembly
Solution Approach 1:
The patent employs dynamic connections through rotation joints between the seat member, foot members, and rocking members, allowing the chair to transform between unfolded and folded states through simple rotational movements rather than complex assembly and disassembly operations. This dynamic design enables compact folding while maintaining ease of operation.
Solution Approach 2:
The chair components are designed to nest within each other when folded, with the foot members and rocking members collapsing into the seat frame structure. This nesting arrangement achieves compact storage volume while the integrated rotational connections keep the folding operation simple and intuitive.
3Device complexity
If the rocking member is integrated into the seat frame to avoid scattered structure, then the device complexity is reduced, but the ease of operation may worsen if detaching is required
Solution Approach 1:
The rocking member is designed with rotation joints that allow it to pivot between the seated and folded positions. This dynamic connection eliminates the need for detaching operations while maintaining the integrated structure, as the rocking member can be freely positioned through rotation rather than requiring assembly or disassembly.

AI summary
A folding rocking chair includes two supporting portions. Each supporting portions includes a first support, a second support, a stand member, a first rocking member, a second rocking member, a first foot member and a second foot member. The stand member, the first rocking member and the second rocking member are all rotatably connected with the first support. The first foot member is rotatably connected with the first rocking member. The second foot member is rotatably connected with the second rocking member. The first foot member and the second foot member are rotatably connected with the second support. The second foot member is rotatably connected with the stand member and is slidable along the stand member. A seat member is rotatably connected with the stand member and the first foot member and is telescopically moveable.
