Solution Overview
Problem
Existing cutting tools for floor coverings suffer from limited dimensional accuracy and complexity, resulting in visible gaps between cutouts and openings.
Innovation Solution
A cutting tool with a stable holder made of metal or fiber-reinforced plastic, featuring ball bearings at corners for smooth guidance, suction cups for secure positioning, and adjustable blades for precise cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting tools are used, then the cutting process can be completed, but dimensional accuracy is limited and gaps are created between cutout and opening
Solution Approach 1:
The cutting tool is divided into separate functional components: a holder that remains stationary on the floor covering and a blade holder that rotates independently to perform the cutting motion. This segmentation allows the holder to provide a stable reference frame while the blade holder executes the precise cutting action, improving dimensional accuracy without requiring the entire tool to be complex.
Solution Approach 2:
The blade holder is nested within the holder structure, with the blade holder rotating inside the stationary holder. This nested configuration allows the cutting blades to be positioned precisely relative to the holder's reference surface, enabling accurate cutting while keeping the overall tool structure compact and manageable.
2Stability of the object's composition
If the holder is made thicker and more stable, then guidance smoothness improves, but device complexity and material usage increase
Solution Approach 1:
The holder is designed with enhanced thickness and stability specifically at the regions that contact the blade holder and provide guidance surfaces. The holder has a wall thickness of 25-35 mm at critical areas to ensure smooth guidance, while other parts of the structure can be more economical. This localized reinforcement provides the necessary stability without unnecessarily increasing overall device complexity.
3Ease of operation
If multiple bearings are arranged at corners and edges, then running smoothness improves, but manufacturing complexity increases
Solution Approach 1:
Multiple bearings are combined into a single integrated bearing arrangement system that supports the blade holder at its corners and edges. The bearings are arranged in a coordinated pattern where multiple bearings work together as a unified guidance system, providing smooth running throughout the cutting motion while simplifying the overall manufacturing process compared to separate bearing installations.
4Manufacturing precision
If fixing devices with suction cups are added, then positioning accuracy improves, but device complexity increases
Solution Approach 1:
Suction cups are integrated into the holder to provide pneumatic attachment to the floor covering. The suction cups create a vacuum seal between the holder and the floor surface, firmly securing the holder in the desired position. This pneumatic fixing mechanism achieves high positioning accuracy without requiring mechanical clamps, screws, or other complex mechanical fixing devices.

AI summary
The invention relates to a cutting tool or a cutting device or a cutting tool designed for cutting out a section of a preferably air-impermeable floor covering lying on a substrate, e.g. a carpet, linoleum, vinyl or the like, with a holder that can be placed on the floor covering and a blade holder arranged in this holder and movable relative to the holder via an actuating element, which blade holder is rotatable to perform a cutting movement. One or more blades are attached to the blade holder in such a way that they cut into the floor covering when the cutting movement is performed in order to cut the section out of the floor covering.
