Decorative Panel Interlock Structure for Leak-Resistant Floor Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative panels are not leak-proof, allowing liquids to pass through connection points and collect under or penetrate into the floor, leading to potential damage.
Innovation Solution
A decorative panel design with specific geometrically designed connecting elements on long and short edges that create contact-free spaces and optimized surface angles to prevent liquid penetration, using mineral-filled polymer materials for flexibility and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connecting means are used to join panel edges, then the panels can be detachably connected, but liquid can pass through the connection points and collect under or penetrate into the floor
Solution Approach 1:
The connecting means are designed with nested structures where hooks fit into grooves and locking lugs engage with locking grooves, creating a multi-level nested connection system that prevents liquid penetration while maintaining compact dimensions
Solution Approach 2:
The connection structure extends into the third dimension with vertical hooks and grooves that interlock, creating a Z-shaped connection path that blocks liquid flow from the panel top surface through to the bottom
2Ease of manufacture
If auxiliary tools like shims are used to join panel edges, then the connection can be achieved, but additional components and assembly steps are required
Solution Approach 1:
The connecting means integrate multiple functions into a single integrated structure combining hooks, grooves, locking lugs, and locking grooves into one unified connection element that eliminates the need for separate shims and auxiliary tools
Solution Approach 2:
The connecting means are designed to self-align and self-lock through the geometric interlocking of hooks and grooves, requiring no auxiliary alignment tools or complex assembly procedures
3Ease of operation
If disassembly is performed on panels with hook elements, then the panels can be separated, but high stress is placed on retaining profiles causing cracks and breaks
Solution Approach 1:
The connection structure allows controlled dynamic movement during assembly and disassembly through the flexible engagement of hooks with grooves, enabling separation while distributing stress away from critical hook points
Solution Approach 2:
The locking lugs and locking grooves are positioned to engage before full assembly is complete, providing progressive stress distribution and cushioning during the assembly and disassembly process to prevent sudden stress spikes

AI summary
The invention relates to a decorative panel comprising a panel core, a panel top and a panel bottom, and at least four panel edges arranged in pairs opposite each other, with complementary connecting means provided in pairs on the panel edges, which fit together in such a way that identical panels can be attached to one another. The connecting means are designed in such a way that the passage of liquid located on the panel top through the connecting means is prevented.
