Rocking Chair Concealed Joint Structure for Easy Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rocking chairs have complex and aesthetically undesirable interconnections between parts, making them difficult to disassemble and maintain a clean appearance.
Innovation Solution
A disassemblable rocking chair design featuring a back panel member with bolt holes, armrests with latch members, a seat panel with connecting elements, and a base member, which allows for concealed connections between the seat panel and base member when assembled, using a spring plate for flexibility and shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional interconnections are used between chair parts, then structural stability is achieved, but aesthetic appearance deteriorates due to evident and complex connections
Solution Approach 1:
The connection elements are extracted and concealed within the closed region below the first spindle of the armrests, removing the visual disturbance from the aesthetic view while maintaining structural function
Solution Approach 2:
The connection elements are nested within the closed region of the armrest structure, placing one object (connection element) inside another (armrest closed region) to achieve concealment while maintaining structural integrity
2Reliability
If multiple connecting elements are used to ensure stable connections, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The closed region below the first spindle serves multiple functions: it acts as a structural component of the armrest, provides aesthetic concealment, and houses the connection elements, thereby reducing overall device complexity
Solution Approach 2:
The connection elements are merged with the armrest structure by positioning them within the closed region, combining structural and connection functions into a single integrated component
3Stability of the object's composition
If fixed connections are used between chair parts, then structural stability is maintained, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The connection is made dynamic and adjustable by using the latch mechanism that can be engaged or disengaged, allowing the structure to transition between fixed and separated states while maintaining stability when connected

AI summary
A disassemblable rocking chair including a back panel member, opposing armrests, a seat panel, a spring plate, and a base member is provided. The back panel member includes first connecting elements to connect to second connecting elements of the opposing armrests and to third connecting elements of the seat panel. The spring plate includes fourth connecting elements to connect to the third connecting elements of the seat panel and to fifth connecting elements of the base member. A closed region is defined below a first spindle connecting opposing sides of each opposing armrest. The seat panel includes a wall member perpendicularly connected to a front side of its horizontal seat member. A connection between the closed region on each opposing armrest, the wall member of the seat panel, and the back panel member conceals a connection between the seat panel and the base member below the seat panel.
