Solution Overview

Problem

Existing floor panel coupling systems, particularly 'push-lock' systems, face challenges in maintaining uniform height and stability due to lack of precise vertical locking, especially in thin panels with limited space for locking elements, leading to potential height differences and operational difficulties during installation.

Innovation Solution

The development of a floor panel with a vertically active locking system featuring a pivotable lock-up body and a coextruded synthetic material strip, where the lock-up body forms a stop-forming locking portion and is oriented at an angle less than 60° in the non-coupled condition, allowing for a more gradual locking mechanism and improved stability, even in thin panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate locking element (insert) is used to provide vertical locking, then vertical locking capability is improved, but device complexity increases

Engineering Contradiction:
Improvevertical locking capabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the horizontal locking system (male and female coupling parts) and the vertical locking system (locking element with lock-up body) into a single integrated coupling assembly. The locking element is positioned within the female coupling part, creating a unified structure that provides both horizontal and vertical locking functions simultaneously, thereby improving reliability without proportionally increasing complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling parts are designed to perform multiple functions: the male coupling part provides both the horizontal engagement surface and support for the locking element, while the female coupling part integrates the lock-up body that performs both vertical locking and guides the horizontal insertion. This multi-functionality reduces the need for separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the panel thickness is reduced, then ease of installation and aesthetics are improved, but space for locking elements is limited

Engineering Contradiction:
Improveinstallation easeVSAvoidspace for locking elements
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The lock-up body is designed to pivot through a significant angular range (greater than 30 degrees) during the locking operation. This angular movement transforms the limited linear space within the thin panel into an effective locking mechanism by utilizing rotational motion, allowing the locking element to achieve full locking function despite the constrained thickness available for its placement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If a pivotable lock-up body with angular movement is used, then locking smoothness is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvelocking smoothnessVSAvoidangular orientation precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent specifies that the lock-up body adopts an angular orientation in the uncoupled state (greater than 30 degrees) and pivots to a different orientation in the coupled state. This parameter change approach allows for tolerance compensation: the angular movement itself absorbs minor manufacturing variations, as the locking action occurs over a range of angles rather than requiring precise alignment at a single angular position.

Inventive Principle:
Principle #35Parameter changes
