Floor Slab Cutting Device With Inverted Rolling And Merged Cutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor slab cutting devices fail to produce precise, rectilinear grooves in hard materials like concrete, as they lack effective means to maintain alignment and adapt to varying dimensions of drive means, and often result in incomplete satisfaction with the rectilinear appearance of grooves.
Innovation Solution
A floor slab cutting device comprising a vehicle with motorized axles, featuring circular saws that can move from a retracted to a cutting position, and a downstream cutter to hollow out material between grooves, allowing for precise adjustment of groove dimensions and alignment control through interchangeable sleeves and adjustable cutting tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cutting tools are positioned in the front part upstream of rolling means, then cutting can be performed, but the grooves do not offer complete satisfaction with regard to their rectilinear appearance and alignment cannot be maintained
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the rolling means upstream of the cutting tools instead of downstream. This allows the rolling means to establish a straight reference path first, which then guides the cutting tools to follow the same rectilinear trajectory, ensuring perfect alignment and rectilinear appearance of grooves.
Solution Approach 2:
The patent introduces an intermediary alignment system consisting of rolling means that creates a reference path. This intermediary element mediates between the vehicle's movement and the cutting tools, ensuring that the grooves are cut along a perfectly straight line by following the rolling path.
2Productivity
If multiple cutting tools are used to create grooves, then cutting efficiency is improved, but additional tools are needed to excavate material between grooves to form complete grooves
Solution Approach 1:
The patent merges the cutting function and excavation function into a single integrated tool system. The cutting tools create grooves while simultaneously excavating the material between them, eliminating the need for separate excavation tools and reducing overall device complexity while maintaining high productivity.
3Adaptability or versatility
If cutting tools are fixed in position, then structural simplicity is maintained, but the device cannot adapt to varying dimensions of drive means requiring different groove dimensions
Solution Approach 1:
The patent implements dynamic adjustability in the cutting tools, allowing them to be repositioned and reconfigured for different groove dimensions. This dynamic capability enables the device to adapt to various drive means requirements while using relatively simple adjustment mechanisms that can be easily operated.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the creation of grooves with precise dimensions and a perfect surface finish, accommodating various drive means while minimizing vibrations and ensuring the rectilinear alignment of cuts, thus improving the quality and precision of the cutting process.
Implementation Method 1
at least two circular saws driven in rotation along the same axis, so as to simultaneously provide two parallel grooves
Implementation Method 2
at least one cutter driven in rotation downstream of said saws, so as to hollow out the material between the two grooves

AI summary
The device i.e. vehicle (1), has two front bearing axle (2) and rear bearing axles (3), and a cutting unit movable from a retracted upper position to a cut lower position and vice versa. The cutting unit includes two circular saws on a side of the vehicle. The circular saws are driven in rotation along an axis (A-A') so as to simultaneously arrange two parallel kerfs (50, 60). The cutting unit has a cutter that is driven in rotation in downstream of the saws so as to remove material between the kerfs.
