Pivotable Cutting Blade for Flexible Floor Tiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for laminate floorboards and other tough or elastic materials face challenges in achieving high cutting quality due to large gap distances between the cutting blade and support beams, which are not suitable for materials like plastic, rubber, or slate, and often result in unwanted sticking and horizontal forces that can cause warping.
Innovation Solution
A cutting device with a pivotably mounted cutting blade featuring a non-stick coating and teeth with a specific tooth ridge configuration, allowing for a reduced gap distance of approximately 0.7 mm, and a control mechanism that shifts the pivot axis horizontally to minimize horizontal forces during cutting, preventing warping and sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the gap distance between the cutting blade and support beam is reduced to improve cutting quality, then cutting precision improves, but horizontal forces increase causing warping
Solution Approach 1:
The cutting blade is made pivotable about a vertical axis, allowing it to dynamically adjust its position and orientation during the cutting process. This dynamic capability enables the blade to accommodate material deformation without generating excessive horizontal forces, resolving the contradiction between achieving tight gap spacing for quality cuts and avoiding warping-causing forces.
Solution Approach 2:
The invention changes the operational parameters by allowing the cutting blade to pivot and shift position during cutting. This parameter change enables the system to maintain optimal gap spacing (improving cutting quality) while adapting to material resistance, thereby preventing the buildup of harmful horizontal forces that would cause warping.
2Object-generated harmful factors
If the gap distance is reduced to 0.7 mm to prevent sticking, then adhesion decreases, but the device complexity increases due to pivot mechanism
Solution Approach 1:
The pivotable blade mechanism introduces dynamic adjustment capability that simplifies the overall system by eliminating the need for extremely precise static positioning. The blade can naturally adapt to the cutting conditions, reducing sticking through motion rather than requiring complex anti-adhesion systems.
Solution Approach 2:
The cutting blade serves itself by automatically adjusting its position through pivoting during the cutting process. This self-adjustment capability reduces sticking and maintains optimal gap spacing without requiring external control systems or complex mechanisms, thereby reducing overall device complexity.
3Manufacturing precision
If a long handle is added to the cutting blade to reduce gap distance, then cutting precision improves, but ease of operation deteriorates
Solution Approach 1:
Instead of using a long handle to achieve precise positioning, the invention employs a pivotable blade that dynamically adjusts during cutting. This dynamic mechanism maintains cutting precision while keeping the handle length reasonable, preserving ease of operation.
Solution Approach 2:
The invention replaces the mechanical solution of a long handle with a pivotable blade mechanism. This substitution achieves the same precision goal through rotational movement rather than extended leverage, maintaining operator comfort and ease of use.

AI summary
The invention relates to a cutting device, as well as to the use of a cutting device, comprising a cutting blade (10) which is pivotably fixed to a stand (1), the cutting edge (12) of said cutting blade (10) descending into an entry slot (6) between two supporting members (2) during the cutting process in order to press out a strip of material (91) from a panel-shaped workpiece (9) placed on the supporting members (2). The width of the entry slot (6) is adjusted to the material thickness of the cutting blade (10) in such a way that, when the cutting blade (10) is positioned in the centre of the entry slot (6), a gap remains, at least in the region of the cutting edge (12), between each of the two supporting member edges (4') or slot walls (4) and the broad faces (11) of the cutting blade (10), said broad faces (11) lying opposite the supporting member edges (4') or slot walls (4). In order for panels or tiles, in particular floor coverings or roof shingles consisting of synthetic material, rubber or of another tough or elastic material to be cut with sufficiently high cutting quality on the cutting device, it is proposed that the gap (11, 4') measure no more than 0.7 mm for cutting panels or tiles between 1mm and 5mm thick, in particular floor coverings or roof shingles consisting of synthetic material, rubber or of another tough or elastic material.
