Finishing Profile With Adjustable Knife Cutting Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing finishing profiles and sets for floor coverings face challenges in providing versatile and efficient solutions for edge finishing, particularly in creating attractive transitions and expansions between different floor coverings, with limitations in mechanical strength and user-friendliness of cutting tools.
Innovation Solution
A finishing profile comprising a flange-shaped portion made from synthetic materials with a locally reduced wall thickness at the attachment point, allowing subdivision for various applications, and a cutting tool with an adjustable knife for precise cutting, enabling flexible use as end, transition, or expansion profiles, and ensuring sufficient mechanical strength and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flange-shaped portion is made thin to allow subdivision at the attachment portion, then the finishing profile can be divided into multiple functional parts (end profile, transition profile, expansion profile), but the mechanical strength of the flange-shaped portion is reduced
Solution Approach 1:
The flange-shaped portion is designed with a locally reduced wall thickness at the attachment portion, allowing it to be subdivided into multiple functional parts (end profile, transition profile, expansion profile) while maintaining sufficient mechanical strength in the remaining portions. This segmentation enables one finishing profile to serve multiple purposes.
Solution Approach 2:
The wall thickness of the flange-shaped portion is not uniform but varies locally: it is reduced at the attachment portion to facilitate subdivision, while the remaining portions maintain sufficient thickness to provide the necessary mechanical strength and structural integrity for their respective functions.
2Manufacturing precision
If a fixed-position knife is used in the cutting tool, then the cutting tool structure is simple, but the cutting precision and adaptability for different cutting positions are limited
Solution Approach 1:
The knife position in the cutting tool is made adjustable rather than fixed. The knife can be positioned at different locations along the cutting edge to accommodate various cutting requirements and positions on the finishing profile, thereby improving cutting precision and adaptability while accepting increased device complexity.

AI summary
A finishing profile for a floor covering, including at least a flange-shaped portion, which extends on opposite sides of an attachment portion situated on the underside, wherein the flange-shaped portion is formed in one piece from synthetics and is provided for being subdivided at the location of the attachment portion. The invention further also relates to a cutting tool for cutting up such finishing profile for a floor covering, wherein this cutting tool includes a body and includes at least one knife, wherein the position of the knife is adjustable.
