Adjustable Tile Saw Fence for Large Tile Sheet Cutting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tile saws are unable to efficiently accommodate and cut larger tile sheets beyond the standard 8 in×8 in or 12 in×12 in sizes due to limitations in fence adjustment and support mechanisms.

Innovation Solution

The tile saw features an adjustable rear fence that can be pivoted, slid, or translated between operating and bypassed positions, allowing the engagement surface to align with or below the table surface, enabling support for larger tiles by extending beyond the table edge, and includes latch, pin and guideway, spring and detent, and clamp arrangements for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fence is fixed in a standard position, then the tile saw can accurately cut standard-sized tiles (8 in×8 in or 12 in×12 in), but it cannot accommodate larger tile sheets

Engineering Contradiction:

Improvetile size accommodationVSAvoidfence adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fence is made adjustable between a fixed position (for standard tiles) and a movable position (for large tiles). The fence can be shifted along the table surface and locked at different positions, transforming from a static component to a dynamic one that adapts to different workpiece sizes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The fence assembly is divided into separable components including the fence body, locking mechanism, and mounting elements. This segmentation allows the fence to be repositioned and reconfigured easily, enabling accommodation of both standard and large format tiles without requiring a completely different setup.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If the table size is increased to accommodate larger tiles, then larger tile sheets can be supported, but the overall device size and footprint increase

Engineering Contradiction:

Improvetable surface areaVSAvoiddevice footprint

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

Instead of permanently enlarging the table, the invention allows the effective working area to be dynamically extended by positioning the fence further back on the table. This enables large tiles to be accommodated by utilizing the existing table surface more efficiently rather than physically expanding the table structure.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the fence is made adjustable to accommodate various tile sizes, then versatility improves, but the ease of operation decreases due to additional adjustment steps

Engineering Contradiction:

Improvetile size rangeVSAvoidfence adjustment ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fence is pre-equipped with a locking mechanism that allows for quick positioning and securing. The locking feature is designed to be engaged easily, reducing the number of steps required to adjust the fence for different tile sizes. The mechanism is prepared in advance to facilitate rapid reconfiguration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The locking and adjustment functions are extracted as separate, simple mechanisms rather than being integrated into a complex system. This allows the user to perform adjustments by simply moving and locking the fence without dealing with multiple interconnected controls, thereby simplifying the operation.

Inventive Principle:

Principle #2Taking out (Extraction)

4Manufacturing precision

If the engagement surface of the fence is always above the table surface, then support for standard tiles is optimal, but larger tiles cannot extend beyond the table edge

Engineering Contradiction:

Improvecutting accuracyVSAvoidlarge tile support

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The engagement surface of the fence is designed to be adjustable in its vertical position relative to the table surface. It can be positioned above the table for standard tiles to provide optimal support and below the table edge for large tiles to allow them to extend beyond the table. This dynamic positioning resolves the contradiction between precision and adaptability.

Inventive Principle:

Principle #15Dynamics

AI summary

A tile saw includes a saw with a cutting blade, a frame supporting the saw, a table supporting a workpiece and being slidable relative to the frame, and a rear fence secured to the table. The rear fence has an engagement surface and is adjustable between an operating position and a bypassed position. The bypassed position includes the engagement surface of the fence being no higher than even with the planar surface of the table to allow a workpiece to extend beyond a rear edge of the table. In the operating position, the engagement surface of the rear fence projects axially from the planar surface of the table to support the workpiece as the workpiece is pushed into the cutting blade during operation. The fence can be adjusted between the operating and bypassed positions by using any one of a cam lever clamp, pin and guideway, or rotatable latch.
