Floor Panel Locking System Vertical Folding Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor panel locking systems face challenges with separation issues during installation, particularly when using vertical folding or vertical locking, especially with panels of small thickness or compact locking systems, leading to gaps and potential damage to the locking system.
Innovation Solution
The development of enhanced locking systems for both long and short edges with increased friction at specific angles, incorporating flexible tongues and friction-enhancing features such as protrusions or chemicals, to prevent separation during vertical folding, allowing for easier and more reliable installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vertical folding or vertical locking is used to connect floor panels, then installation ease is improved, but separation of short edges occurs leading to gaps and potential damage to the locking system
Solution Approach 1:
The patent applies preliminary anti-action by introducing friction-enhancing features (protrusions or chemicals) on the long edges before the vertical folding operation occurs. These features create friction forces that counteract the separation tendency of short edges during installation, preventing gaps and damage before they can occur
Solution Approach 2:
The patent changes the friction parameter between long edges by adding protrusions or chemical substances. This parameter change increases the friction force during vertical folding, which prevents the short edges from separating while maintaining the ease of vertical folding installation
2Device complexity
If panels of small thickness or compact locking systems are used, then device complexity is reduced, but separation issues during installation increase
Solution Approach 1:
The patent applies local quality by adding friction-enhancing features only at specific locations on the long edges (protrusions or chemical applications) rather than modifying the entire locking system. This localized modification maintains the compactness of the locking system while providing sufficient friction to prevent separation during installation
3Reliability
If increased friction is applied at specific angles during vertical folding, then separation prevention is improved, but manufacturing complexity increases
Solution Approach 1:
The patent changes the friction parameter through simple additions of protrusions or chemical substances on the long edges, which can be integrated into existing manufacturing processes without fundamentally changing the manufacturing approach. This achieves reliable separation prevention while maintaining manufacturing simplicity
