Furniture Panel Fastening Device with Segmented Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assembling furniture panels, such as nailing back panels, require substantial effort, pose hazards, and result in furniture that cannot be disassembled or reassembled.
Innovation Solution
A fastening device with axial and lateral extensions, featuring a dowel and pin system with protrusions and slits that allow for secure assembly and disassembly, enabling the device to take up forces in both directions and facilitate easy reconfiguration of furniture panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If nailing is used to assemble furniture panels, then the assembly is strong and stable, but the furniture cannot be disassembled and reassembled
Solution Approach 1:
The fastening device is divided into two separable parts: a fastening element (dowel) and a locking element (pin). The fastening element is inserted into the panel first, then the locking element is inserted into the fastening element to secure it. This segmentation allows the assembly to be strong when locked while enabling disassembly by simply removing the locking element, thus resolving the contradiction between stability and reusability.
2Strength
If nailing is used to assemble furniture panels, then the assembly is strong, but it requires substantial effort and poses hazards
Solution Approach 1:
The fastening element acts as an intermediary between the locking element and the panel. Instead of directly driving a nail into the panel (which requires hammering effort and poses hazards), the locking element simply inserts into the pre-positioned fastening element. This intermediary mechanism transforms a complex, hazardous operation into a simple, safe insertion action while maintaining strong assembly.
3Ease of operation
If a simple pin insertion system is used, then the assembly is easy and quick, but it cannot effectively resist lateral forces
Solution Approach 1:
The fastening element incorporates protrusions on its outer surface that locally engage with corresponding features in the panel or locking element. These localized protrusions are specifically designed to resist lateral forces, while the overall assembly process remains simple insertion. This local quality enhancement allows the simple pin insertion system to effectively resist lateral forces without compromising ease of operation.
