Hard Floor Panel Beveled Joints for Gap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tongue-and-groove profiles in flooring panels allow gaps to form, leading to moisture and dirt penetration, which causes swelling and increased abrasion of wood-based material panels.
Innovation Solution
A floor panel design with beveled joining surfaces on the tongue and groove profiles that engage to create a line pressure, preventing gaps and ensuring a closed surface contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional tongue-and-groove profiles are used, then installation is simple and easy, but gaps form between panels allowing moisture and dirt penetration
Solution Approach 1:
The invention introduces a beveled joining surface that creates line pressure along the entire contact line between panels, transforming the joining mechanism from point or area contact to continuous line contact. This dimensional change in the joining interface prevents gap formation while maintaining simple installation procedures.
Solution Approach 2:
The invention changes the geometric parameters of the tongue-and-groove profile by adding a beveled joining surface with specific inclination angles. This parameter modification creates line pressure that forces panels together, eliminating gaps without complicating the installation process.
2Object-affected harmful factors
If devices are used to join floor panels, then gap formation is reduced, but application becomes complicated
Solution Approach 1:
The tongue-and-groove profile with beveled joining surfaces is designed to automatically create line pressure and eliminate gaps during installation without requiring external joining devices. The profile itself performs the gap-prevention function, making the installation process simple while achieving the desired sealing effect.
3Shape
If wood-based material boards are used, then aesthetic appearance is improved, but swelling occurs when moisture penetrates
Solution Approach 1:
The beveled joining surface creates line pressure that prevents moisture and dirt from penetrating between panels before they can cause swelling. This preliminary protective action blocks the harmful substances that would otherwise cause the wood-based panels to swell and deform.
4Reliability
If surface layer is exposed to increased abrasion, then durability decreases, but this occurs when gaps allow moisture penetration
Solution Approach 1:
The line pressure created by the beveled joining surfaces prevents moisture penetration that would cause swelling and subsequent surface layer lifting. By preventing the initial moisture ingress, the surface layer remains protected from increased abrasion and maintains its durability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents moisture and dirt ingress, reducing panel swelling and abrasion by maintaining a sealed joint between panels.
Implementation Method 1
When the beveled joining surface of the tongue profiling and the beveled joining surface of the groove profiling are in contact in the joined state of at least two floor panels, a line pressure occurs along the beveled joining surfaces of the side edges of the tongue profiling and the groove profiling at the contact points.
Implementation Method 2
the projection of the tongue engages the recess of the lower lip of the groove so that the contact surfaces of the projection of the tongue and the recess of the lower lip of the groove exert a tensioning force on each other
