Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical tile cutters do not allow for simultaneous cutting of multiple tiles, leading to inefficiencies and health hazards from dust and noise during cutting, while existing CMU cutting methods are time-consuming and require precise measurement.
Innovation Solution
A mechanical tile cutting device with a long breaker bar that simultaneously scores and cuts multiple tiles, and a CMU scoring device with opposing scoring chisels that precisely score and split CMUs without the need for electrical power or water, using a breaker bar and scoring chisels to apply force along a cutting axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a circular electric saw or grinder is used to cut tiles, then cutting speed is improved, but ceramic dust generation increases causing health problems
Solution Approach 1:
The patent replaces the electric motor-driven diamond blade system with a manual mechanical scoring and breaking system. The scorer creates a fracture line by scratching the tile surface, and the breaker bar applies mechanical force to snap the tile along the score line, eliminating the need for high-speed rotation and water cooling that generate dust.
Solution Approach 2:
The invention extracts and removes the dust-generating components (electric motor, rotating diamond blade, water pump) from the cutting system, retaining only the essential mechanical scoring and breaking functions that can be performed without generating harmful dust.
2Object-generated harmful factors
If a wet saw with rotating diamond blade is used, then dust is reduced, but device complexity and cost increase
Solution Approach 1:
The patent replaces the complex wet saw system (motor, blade, pump, water circulation) with a simple manual mechanical system consisting of a scorer and breaker bar, achieving dust-free operation without the complexity of water circulation systems.
Solution Approach 2:
The invention uses simple, inexpensive mechanical components (scorer tip, breaker bar) that can be easily replaced if needed, rather than investing in expensive, complex wet saw equipment with multiple moving parts and maintenance requirements.
3Object-generated harmful factors
If current mechanical tile cutters are used, then dust and noise are reduced, but only single tile cutting is possible reducing productivity
Solution Approach 1:
The patent merges multiple scoring and breaking operations into a single device by providing multiple scorers and breaker bars that can simultaneously process multiple tiles, combining the benefits of low-dust operation with increased productivity through parallel processing.
Solution Approach 2:
The device achieves multi-functionality by enabling simultaneous scoring and breaking of multiple tiles with different size requirements, allowing one device to perform what previously required multiple sequential operations on separate devices.
4Speed
If CMU is cut with electric saw, then cutting speed is improved, but loud noise and dust generation occur
Solution Approach 1:
The patent replaces the electric saw system with a manual mechanical scoring and breaking system for CMU, using a scorer to create fracture lines and a breaker bar to snap the blocks, eliminating noise and dust while maintaining adequate cutting speed for construction applications.
5Object-generated harmful factors
If chisel and masonry hammer are used to split CMU, then no dust or noise is generated, but the process is time consuming and requires precision measurement
Solution Approach 1:
The patent combines the scoring and breaking functions into a single integrated device with multiple scorers and breaker bars that can simultaneously process multiple CMU, dramatically reducing the time required compared to sequential chisel and hammer operations while maintaining dust-free and quiet operation.
Solution Approach 2:
The device performs preliminary scoring of multiple CMU simultaneously before breaking, creating all necessary fracture lines in advance and then applying breaking force to split the blocks along the pre-scored lines, eliminating the need for repeated measurement and scoring during the breaking process.
