Wall Hanger Multi-Directional Coupling for Assembly Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall hangers suffer from poor assembly stability due to single-direction coupling of brackets with vertical columns, leading to loosening or falling off under external forces from different directions.
Innovation Solution
A wall hanger design featuring vertical columns with opposing sidewalls and a connecting member, where the bracket's arm engages with coupling holes on both sidewalls, providing a nearly annular enclosing approach for enhanced stability, with tightening walls and hooked portions to secure the bracket and distribute weight evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If brackets are fixed by single-direction engagement between coupling members and coupling holes, then assembly is simple, but assembly stability is poor
Solution Approach 1:
The patent transitions from single-direction coupling to multi-directional coupling by adding coupling holes in both vertical and horizontal directions on the vertical column, and corresponding coupling members on brackets that engage in multiple directions simultaneously, fundamentally changing the coupling dimensionality to improve stability
Solution Approach 2:
The patent employs asymmetric coupling hole arrangements where vertical coupling holes and horizontal coupling holes are positioned at different locations and orientations, creating an asymmetric engagement pattern that prevents loosening under various external forces while maintaining assembly simplicity
2Device complexity
If brackets are engaged in a single coupling direction, then the structure is simple, but the brackets are apt to loosen under external forces
Solution Approach 1:
The patent adds horizontal coupling dimensions to the traditional vertical coupling arrangement, creating a three-dimensional coupling system where brackets engage with the vertical column through both vertical and horizontal coupling members, significantly improving resistance to loosening under external forces
Solution Approach 2:
The patent incorporates tightening walls with inclined surfaces that automatically tighten the coupling engagement when external forces are applied, performing the tightening action preliminarily and continuously to maintain reliable connection without additional complexity
