Quartz Slab Vein Simulation via Crack Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quartz-based engineered stone lacks natural, random-looking veins and color patterns, which are characteristic of natural stones like marble and granite, making it less aesthetically appealing.
Innovation Solution
An apparatus and method that introduces controlled cracks in a soft or damp quartz slab and sprays colored materials into these cracks using a system of lift bars and spray bars with nozzles, aligned and rotated by servo motors and controlled by a computer processor to simulate natural vein patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional quartz slab production methods are used, then the manufacturing process is simple and production efficiency is high, but the slabs lack natural, random-looking veins and color patterns
Solution Approach 1:
The patent applies preliminary action by creating cracks in the quartz slab before the coloring process. The crack creation device forms cracks in the damp quartz slab, and then colored material is sprayed into these pre-formed cracks. This preliminary structural preparation enables the subsequent coloring step to produce realistic vein patterns that mimic natural stone, resolving the contradiction between simple manufacturing and aesthetic quality.
2Reliability
If multiple separate devices are used for crack creation and coloring, then each function is performed optimally, but the overall system complexity increases
Solution Approach 1:
The patent merges the crack creation device and the colored material spraying device into a single integrated apparatus. The crack creation device and spraying device are positioned and coordinated to work together on the moving quartz slab, with the spraying device applying colored material directly into the cracks created by the crack creation device. This integration maintains functional reliability while reducing overall system complexity compared to using completely separate devices.
3Strength
If the quartz slab is processed in a hard, cured state, then structural integrity is maintained, but cracks cannot be effectively formed or colored
Solution Approach 1:
The patent applies parameter changes by processing the quartz slab in a damp, uncured state during the crack creation and coloring operations. In this soft state, the slab can be easily cracked and accept colored material into the cracks. After the veins are formed, the slab is then cured to achieve its final hard, structurally integrity state. This temporal separation of material state parameters enables both easy crack formation and final structural strength.

AI summary
An apparatus including a device which moves a first portion of a soft, damp, and/or wet slab out of alignment with a majority of the slab and thus introduces a first crack in the slab; and a device for spraying a first colored material into the first crack of the slab. The device which moves the first portion of the slab out of alignment with the rest of the slab may include a first lift bar. The device for spraying the first colored material in the first crack of the slab may include a first spray bar having a plurality of nozzles fixed thereto, arranged in a substantially straight line. In at least one embodiment, the apparatus may also include a device which moves a second portion of the slab out of alignment with the majority of the slab and thereby introduces a second crack in the slab.
