Height Overlay Trim Strip for Floating Floors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover strips for floating floor coverings, particularly those made of thin, elastic materials like PVC or LVT, face challenges in aesthetically pleasing installation and ensuring lateral expansion, as they require significant lengthening of cover legs or time-consuming gluing, which impedes expansion and can lead to arched floor coverings.
Innovation Solution
A cover strip design featuring a height support that allows the same base profile to be used for various flooring thicknesses, with a height support that can be dispensed with for thin coverings and adapted for thicker ones, enabling easy installation and a broader range of applications by using a standardized cover strip with a screw connection and optional snap-in mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cover legs of the cover profile are lengthened significantly to overlap with thin floor coverings, then the covering can be covered, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent introduces an intermediate height support element positioned between the base profile and the cover profile. This height support acts as a mediator that raises the cover profile to the appropriate height level, allowing the cover legs to effectively overlap with thin floor coverings without requiring the cover legs themselves to be excessively long, thus maintaining aesthetic appearance while achieving adaptability to thin coverings
2Ease of manufacture
If only a cover profile is used for thin floor coverings, then installation is simplified, but the covering cannot be properly covered due to height mismatch
Solution Approach 1:
The patent segments the cover strip into three distinct components: a base profile for anchoring to the subfloor, a height support element for height adjustment, and a cover profile for covering the joint. This segmentation allows each component to perform its specific function independently, enabling the same base profile and cover profile to be used with different thicknesses of floor coverings by simply changing the height support element
3Adaptability or versatility
If gluing is used to attach the cover profile to thin floor coverings, then the covering can be covered, but lateral expansion is impeded leading to arched floor coverings
Solution Approach 1:
The height support serves as an intermediary that provides the necessary height adjustment without requiring adhesive bonding between the cover profile and the thin floor covering. The mechanical height adjustment allows the cover legs to reach the covering while maintaining the floating floor's ability to expand laterally, thus achieving adaptability to thin coverings while preserving expansion capability
4Adaptability or versatility
If intermediate profiles with complex structure are used for height compensation, then adaptation to different covering thicknesses is achieved, but device complexity increases
Solution Approach 1:
The patent simplifies the intermediate profile by segmenting it into a separate height support element that interfaces only with the base profile, rather than creating a complex integrated intermediate profile that must connect to both base and cover profiles. This segmentation reduces structural complexity while maintaining adaptability to different covering thicknesses

AI summary
The support has a fastening unit for fastening a lower base profile (1) of a covering strip to the support, where the covering strip includes a covering profile. Upwardly directed bars stand in engagement in a corresponding fastening groove at the base profile, and are formed in an inwardly-directed nose. A receiving chamber for the base profile is provided between the bars, where the base profile includes a base plate (11) and two upwardly directed legs (12). The base plate includes a bore hole (13) for a screw connector for fastening the base profile between the legs. An independent claim is also included for a shrouded-type panel.
