Floor Sheet Groove Cutter with Integrated Guide Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing groove cutters for floor sheets face challenges in forming uniform, accurate concave grooves without using a ruler, especially on large surfaces with irregularities, and struggle to maintain stability and follow curved seams effectively.
Innovation Solution
A groove cutter design featuring a non-rotating thin guide plate for seam alignment, a detachable or slidable second blade for deeper cuts, and adjustable rollers or wheels for stability, allowing the tool to follow surface irregularities and cut curved seams without a ruler, with a design that includes a movable front plate and a stabilizing member to enhance operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a ruler is used to guide the cutter for forming grooves along seams, then the groove cutting precision and uniformity are improved, but the operation time and effort increase immensely for long seams
Solution Approach 1:
The invention extracts the guiding function from the ruler and integrates it into the cutter body itself through guide plates and rollers. This eliminates the need for a separate ruler tool, allowing the cutter to self-guide along the seam while maintaining precision and reducing operation time.
Solution Approach 2:
The invention merges the cutting function and guiding function into a single integrated cutter unit. The guide plates and rollers are combined with the cutting blade in one tool, enabling simultaneous guidance and groove formation without requiring separate operations or tools.
2Ease of operation
If the support structure has a long distance between contact points and grip, then the tool has better reachability, but the stability is limited and the tool is easy to break
Solution Approach 1:
The invention introduces dynamic elements including a movable front plate that can slide along the seam and adjustable rollers that can move to accommodate surface irregularities. This dynamic design maintains tool stability while adapting to different working conditions and seam positions.
Solution Approach 2:
The cutter is divided into segmented components including the front plate, rollers, and cutting blade that can move independently. This segmentation allows each part to perform its specific function while maintaining overall tool stability and reducing stress concentration.
3Adaptability or versatility
If front rollers are used to guide the seam, then the tool can follow the seam, but the rollers run off from the seam and cause risk to cut off parts other than the seam
Solution Approach 1:
The invention introduces guide plates as intermediary elements that run along the seam surface without cutting it. These guide plates serve as mediators between the tool and the seam, providing accurate positioning and preventing the cutting blade from deviating or cutting into adjacent areas.
Solution Approach 2:
The guide plates and rollers make preliminary contact with the seam to establish proper tool positioning before the cutting blade engages. This preliminary action ensures the tool is correctly aligned and prevents accidental cutting of wrong parts.
4Stability of the object's composition
If the rear roller is made wider to improve stability, then the guiding capability is enhanced, but the device cannot follow surface irregularities and requires detachment for curved grooves
Solution Approach 1:
The rear roller is designed with dynamic characteristics allowing it to move and adjust its position to follow surface irregularities. This dynamic design maintains stability while adapting to varying seam conditions and curved geometries without requiring detachment.
Solution Approach 2:
The invention allows for parameter changes in the roller system including adjustable width and position. This enables the roller to adapt its characteristics to match different seam conditions, maintaining both stability and adaptability across various working scenarios.

AI summary
A groove cutter for floor sheets which is a tool capable of being operated without using a ruler and can cut a seam, which is created when sheets are laid sequentially on the surface of floor base with an adhesive agent, so that a groove formed along the seam can bridge over both adjacent sheets, comprising a front part, a middle part, a rear part, wherein the front part has a thin guide plate, which is to be inserted into the seam and guides the said tool along the said seam when pushing the tool forward, at the front end, and at least one blade to cut a concave groove at the seam part of the above sheet, which is provided behind the guide plate so as to be detachable, and also a stabilizing member provided at the rear part, which is to be inserted into the concave groove, to stabilize a direction of movement of the tool along the seam.
