Furniture Coupling Assembly for Tool-Free Square and Round Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ready-to-assemble furniture assembly is complicated and often requires tools, and manufacturing limitations restrict the production of shapes like squares and rounds due to laminate wrapping challenges.
Innovation Solution
A furniture coupling assembly with a center portion and two locking members that can be inserted into corresponding grooves on furniture members, allowing for tool-free assembly and forming of square or round components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If common fasteners such as screws, bolts, dowel pins and cam and dowel assemblies are used to assemble RTA furniture, then the furniture members can be joined together, but the assembly process becomes complicated and requires the use of tools
Solution Approach 1:
The coupling device is divided into multiple functional segments: a body portion with a groove for receiving furniture members, and a separate locking member that engages with the furniture members. This segmentation allows the coupling to be inserted without tools while the locking member provides secure fastening, thus simplifying assembly operations while maintaining connection strength.
Solution Approach 2:
The coupling device acts as an intermediary component between furniture members, providing a tool-free connection mechanism. The coupling body receives the furniture members in its groove while the locking member secures them, eliminating the need for traditional tool-based fasteners and simplifying the assembly process.
2Adaptability or versatility
If traditional manufacturing processes with laminate wrapping are used, then furniture members can be produced, but the shapes are limited and square or round components are difficult to manufacture
Solution Approach 1:
The coupling device enables furniture members to be joined in configurations that create square or round shapes by arranging members in specific spatial dimensions. The groove geometry and locking mechanism allow members to be positioned at precise angles relative to each other, enabling the formation of multi-dimensional shapes like squares and circles that were previously difficult to manufacture with traditional laminate-wrapping methods.

AI summary
A furniture coupling assembly that includes a coupling having a center portion, a first portion having a first locking member, a second portion having a second locking member, a first end and a second end. The assembly further includes a first furniture member having a first member groove having a shape corresponding to the center, first and second portions of the coupling. The first furniture member has a first locking member opening positioned adjacent to the first member groove. A second furniture member of the assembly has a second member groove having a shape corresponding to the center, first and second portions of the coupling. The second furniture member has a second locking member opening positioned adjacent to the second member groove. The coupling is insertable in the first and second furniture member grooves and the first and second locking members are insertable in the first and second locking member openings, respectively, to join together the first and second furniture members.
