Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor panels are complex to install and require intricate locking systems that can interfere with material expansion and contraction, leading to potential disengagement.
Innovation Solution
Floor panels with a combination of mechanical locking systems on one pair of edges and edge configurations on the other pair that allow for easy alignment without mechanical locking, using overlapping or adhesive means, enabling simple installation and accommodating material expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical locking systems are applied on all edges of floor panels, then coupling strength and stability are improved, but installation complexity and interference with material expansion increase
Solution Approach 1:
The floor panel edges are segmented into two distinct types: a first pair of opposite edges equipped with coupling parts forming mechanical locking systems, and a second pair of opposite edges with edge configurations free from mechanical horizontally active locking systems. This segmentation allows different functional requirements to be met on different edges, resolving the contradiction between coupling strength and installation complexity.
Solution Approach 2:
Different edge configurations are applied to different pairs of edges based on local requirements. The first pair of edges uses mechanical locking systems where coupling strength is prioritized, while the second pair uses simpler edge configurations where ease of installation and material expansion accommodation are prioritized. This local differentiation resolves the contradiction by applying the appropriate solution only where needed.
2Stability of the object's composition
If mechanical locking systems are used on all edges, then panel stability is improved, but material expansion and contraction are restricted causing potential disengagement
Solution Approach 1:
The edge configurations are segmented into mechanical locking systems on the first pair of edges for stability, and non-locking edge configurations on the second pair of edges for expansion accommodation. This segmentation allows the floor covering to maintain stability where needed while adapting to thermal expansion elsewhere.
Solution Approach 2:
The edge configuration parameters are changed between the two pairs of edges: the first pair uses rigid mechanical locking parameters for stability, while the second pair uses flexible edge configuration parameters that allow for material expansion and contraction without disengagement.
3Reliability
If complex profiled edge parts are applied, then locking effectiveness is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The edge parts are segmented into two types: complex profiled edge parts with locking systems on the first pair of edges where locking effectiveness is critical, and simpler edge configurations on the second pair of edges where manufacturing simplicity is prioritized. This segmentation reduces overall manufacturing complexity while maintaining necessary locking effectiveness.

Function Achieved in This Case
Facilitates easy installation and effective locking while allowing for material expansion and contraction without disengagement, enhancing user-friendliness and durability.
Implementation Method 1
these coupling parts form a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, as well as form a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels
Implementation Method 2
at least one of the overlapping portions is provided with adhesive means, which offer an additional connection which is at least active in vertical direction

AI summary
A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.
