Building Panel Locking Lips for Moisture-Sealed T-Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminate flooring systems suffer from moisture control issues, particularly at the T-joints, leading to potential water penetration and alignment challenges during installation and reinstallation.
Innovation Solution
A building panel design featuring a first mechanical locking system for vertical and horizontal locking with folding motion, and a second locking system for vertical and horizontal locking with vertical folding, incorporating lip portions that form a tight fit and continuous seal to prevent moisture penetration, using a combination of lip portions and optional pockets for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical locking systems are used for easy installation and reinstallation, then ease of operation is improved, but moisture control and sealing between panels deteriorates
Solution Approach 1:
The locking system is divided into separate functional components: a locking tongue for mechanical interlocking and a sealing lip for moisture barrier. This segmentation allows each component to specialize in its function—the tongue provides easy mechanical connection while the lip provides continuous moisture sealing, resolving the contradiction between ease of installation and moisture control.
Solution Approach 2:
A sealing lip acts as an intermediary element between the mechanical locking components and the panel surfaces. This lip creates a continuous seal that bridges the gap between the mechanical locking function and the moisture barrier requirement, enabling both easy assembly and effective moisture protection to coexist.
2Ease of operation
If mechanical locking systems are used for easy installation, then ease of operation is improved, but alignment precision of assembled panels deteriorates
Solution Approach 1:
The locking tongue and groove are pre-configured with precise geometric relationships during manufacturing, including the positioning of the sealing lip relative to the locking features. This preliminary action ensures that when panels are assembled, the alignment is automatically established by the pre-formed mechanical interface, providing both ease of installation and precise alignment without requiring additional adjustment operations.
3Adaptability or versatility
If T-joints are used for panel assembly, then adaptability and versatility are improved, but moisture control and water penetration resistance deteriorates
Solution Approach 1:
The sealing lip functions as a flexible membrane that can accommodate the geometric complexity of T-joint configurations. The lip extends continuously through the joint geometry, maintaining the moisture barrier function even in the more complex T-joint assembly, thus preserving water penetration resistance while enabling versatile panel assembly configurations.

AI summary
Building panels, such as a floor panels or wall panels. The panels include a first mechanical locking system at respective parallel and opposite third and fourth edges, such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels, preferably by means of a folding motion. The panels further include a second locking system at respective parallel and opposite first and second edges, such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels. An upper edge portion of one of the third edge or fourth edge, preferably the third edge, includes a first lower lip portion configured to cooperate with a first upper 10 lip portion of an upper edge portion of the other of the third and fourth edge of an adjacent panel when the third and fourth edges are arranged in locking engagement.
