Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stone slab processing techniques are labor-intensive and time-consuming, particularly in cutting and fabricating stone slabs for applications like countertops and sinks, where precision and aesthetic considerations are crucial. Existing methods often result in inefficient cutting processes, excessive waste, and the need for multiple machines and laborers.
Innovation Solution
A dual work table slab processing machine equipped with a 5-axis machining head and a laser projector system, allowing for simultaneous cutting, routing, and finishing of stone slabs on two tables. The machine positions slabs upside down on vacuum pods, enabling precise cutting and minimizing waste by reducing overcuts and table friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a circular saw blade is used to cut sink holes in stone slabs, then cutting speed is improved, but cutting precision deteriorates due to blade friction and heat against the table surface
Solution Approach 1:
The patent inverts the traditional cutting arrangement by positioning the stone slab above the circular saw blade rather than the blade above the slab. This inversion allows the blade to cut the slab without contacting the table surface, eliminating friction and heat buildup that previously degraded cutting precision while maintaining high cutting speed
2Ease of manufacture
If traditional bridge saws are used for slab cutting, then cutting capability is achieved, but material waste increases due to required overcuts for blade travel
Solution Approach 1:
The patent replaces the traditional bridge saw mechanical system with a CNC-controlled circular saw system that uses digital positioning and computer numerical control. This substitution enables precise control of blade travel distance, eliminating the need for excessive overcuts and reducing material waste while maintaining cutting capability
3Manufacturing precision
If multiple phases of slab processing are performed sequentially, then processing completeness is achieved, but processing time increases
Solution Approach 1:
The patent merges multiple processing phases (cutting, routing, and finishing) into a single integrated CNC machine system. The machine can perform all three phases on the same slab without requiring removal or repositioning, achieving complete processing while significantly reducing total processing time compared to sequential operations on separate machines
4Ease of operation
If manual repositioning of slabs is performed between cutting operations, then operation flexibility is maintained, but labor intensity and time consumption increase
Solution Approach 1:
The patent implements automatic slab positioning and repositioning through CNC control systems that manage slab placement, cutting operations, and repositioning automatically. The system serves itself by eliminating the need for manual intervention between operations, maintaining operational flexibility through programmable sequences while dramatically improving processing efficiency

AI summary
A dual work table, slab processing machine includes first and second work tables, a 5-axis machining head and at least one drive mechanism that drives the machining head along a frame over a slab processing area. The machining head mounts a circular saw blade, a finger bit or at least one finishing tool for respective cutting, routing or finishing of stone or stone-like slabs positioned on the first and second work tables upside down with a finished face down on vacuum pods. A controller positions a first slab upside down with the finished face down and operates the 5-axis machining head to cut, rout and finish the first slab on the first work table, and align a second slab upside down with the finished face down on vacuum pods positioned on the second work table for subsequent cutting, routing and finishing of the second slab.
