Disassemblable Furniture Joint With Hidden Locking Bar Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dismountable furniture often has exposed and cumbersome connecting elements that are aesthetically unpleasing, pose safety risks, and can unintentionally loosen, making them difficult to operate.
Innovation Solution
The design incorporates form-fitting recesses and projections with a hook-shaped or mushroom-shaped form-fitting pair, along with a locking mechanism that ensures secure and easy operation by hiding the connecting elements within the column element, preventing unintentional loosening and allowing for space-saving stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connecting elements are exposed and free-standing, then assembly and disassembly can be performed, but safety risks increase and aesthetics deteriorate
Solution Approach 1:
The connecting elements are nested within the column element housing. The locking bar, form-fitting projection, and other connection components are contained inside the column element, making them invisible and inaccessible during use, thereby eliminating safety risks while preserving assembly functionality.
Solution Approach 2:
The harmful exposed connecting elements are extracted from the external view and relocated into the interior of the column element. Only necessary interaction points (like the actuating element) remain accessible, while the problematic exposed components are removed from the external environment.
2Ease of operation
If connecting elements are exposed and free-standing, then assembly can be performed, but aesthetic appearance deteriorates
Solution Approach 1:
All connecting elements including the locking bar, form-fitting projection, and connection components are nested within the column element housing. This creates a clean, seamless aesthetic appearance while maintaining full assembly functionality through the integrated design.
3Ease of operation
If conventional connecting elements are used, then assembly can be performed, but unintentional loosening occurs
Solution Approach 1:
The locking bar with locking wedge provides preliminary anti-action by continuously engaging with the form-fitting projection to prevent unintentional loosening. The spring element maintains constant locking force, and the anti-loosening design ensures the connection remains secure against vibrational or accidental forces.
Solution Approach 2:
The form-fitting connection is established preliminarily through the hook-shaped projection engaging the recess, and then the locking bar is activated to secure this connection before any operational forces are applied, preventing unintentional loosening from the outset.
4Reliability
If conventional connecting elements are used, then assembly can be performed, but operation becomes cumbersome
Solution Approach 1:
The complex conventional connecting elements are extracted and replaced with a simplified actuating mechanism. The actuating element provides a single-motion interface that internally triggers the locking bar and spring mechanism, reducing external operational complexity while maintaining internal security features.
