Tile Saw Laser Guide and Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tile cutting tools, such as hand tools and wet tile saws, are difficult to operate, time-consuming, and unsuitable for cutting certain materials, and wet tile saws are cumbersome, messy, and prone to miss-cuts due to water splashing and shifting tiles during cutting.
Innovation Solution
A tile cutting machine with a tub containing water and a holding mat with nubs to support tiles, featuring a movable cutting head assembly with a blade positioned for full penetration through the tile and into contact with water, facilitated by a rail system for precise movement and alignment, reducing the need for manual handling and water splashing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wet tile saw with water pump is used to cool and lubricate the blade, then cutting efficiency is improved, but water is sprayed all over leading to mess and water loss
Solution Approach 1:
The patent introduces a water delivery system that acts as an intermediary between the water source and the blade. Instead of using a pump to spray water, the system delivers water directly to the blade through controlled channels, ensuring water reaches the cutting zone without unnecessary dispersion and preventing water from spraying all over the workspace.
Solution Approach 2:
The patent replaces the mechanical water pump spray system with a more controlled water delivery mechanism. This substitution eliminates the harmful effect of water spraying while maintaining the beneficial cooling and lubrication effects on the blade during cutting.
2Productivity
If a stationary saw blade is used and the tile is moved through it, then cutting is achieved, but the tile can shift out of alignment resulting in miss-cut
Solution Approach 1:
The patent inverts the traditional cutting approach by making the blade movable and the tile stationary. Instead of moving the tile through a stationary blade, the blade is moved across the tile on a rail system. This inversion eliminates alignment issues because the tile remains fixed in position throughout the cutting process, and the blade's movement along the rail ensures precise cutting alignment.
Solution Approach 2:
The patent introduces dynamic movement to the blade through a rail system that allows the blade to move horizontally across the tile. This dynamic positioning system enables precise control of the blade's position and movement, ensuring accurate cutting alignment while maintaining the tile in a fixed, stable position.
3Power
If a wide circular blade is used to grind through the tile, then cutting power is sufficient, but the machine becomes cumbersome and difficult to clean
Solution Approach 1:
The patent segments the cutting system into separate, modular components: the blade assembly, the rail system, and the water delivery system. This segmentation allows each component to be independently designed for optimal performance and easily removed for cleaning. The blade can be accessed and cleaned separately from the rest of the machine, simplifying maintenance while maintaining sufficient cutting power.
Solution Approach 2:
The patent uses a smaller, vertically-oriented blade that moves dynamically across the tile rather than a wide circular blade. This dynamic cutting approach maintains sufficient cutting power through the blade's movement and speed, while the smaller blade size reduces machine complexity and makes the overall system easier to clean and maintain.
4Ease of operation
If hand tools like tile nibbers are used to cut tiles, then the tools are simple to operate, but cutting is difficult and time-consuming
Solution Approach 1:
The patent creates a self-service cutting system where the blade automatically moves across the tile along a predetermined path on the rail system. The water delivery system automatically provides cooling and lubrication during cutting. This self-service mechanism eliminates the need for manual manipulation of complex tools while maintaining operational simplicity, significantly increasing cutting speed and efficiency.

AI summary
A tile cutting machine (10) includes a tub (12) for receiving water and a tile (31) to be cut therein. A cutting head assembly (14) having a motor driven blade (46) is positioned above a tile supporting surface located in the tub (12) and is movable with respect thereto. A laser (64) projects a line of light from the cutting head assembly (14) down onto the tile supporting surface to provide a visual representation of a cutting path of the blade (46). A scale permits measurement of a tile (31) to be cut. The laser (64) may be used with the scale to allow a user to quickly determine cutting widths without the need to manually mark the object to be cut. A light source, such as an LED, may be incorporated in the cutting head to illuminate an interior of the tub during operation of the tile cutting machine.
