Engineered stone, particularly quartz-based materials, lack the random color patterns and veining found in natural stone, which are desirable for aesthetic applications.
Innovation Solution
A method and apparatus that combines particulate materials like stone, quartz, and glass with polymer resins, dyes, and binders, using a system of conveyor belts, servo motors, and compression rollers to create layers and reorient fragments, mimicking natural stone patterns, with computer-controlled processes for precise material distribution and pressure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional engineered stone manufacturing methods are used, then production efficiency and material durability are maintained, but the product lacks random color patterns and veining found in natural stone
Solution Approach 1:
The composite material is divided into multiple layers with different color patterns and veining characteristics. Each layer can be independently formed and then combined, allowing complex natural stone patterns to be created through systematic layering rather than attempting to create the entire pattern in a single homogeneous material
Solution Approach 2:
Multiple layers of composite material are stacked and combined together, with each layer containing specific color patterns and veining. The layers are nested within each other to create a multi-dimensional pattern structure that mimics the complexity of natural stone, with each layer contributing specific aesthetic elements
2Manufacturing precision
If multiple layers of composite material are stacked to create patterns, then aesthetic appeal is improved, but material distribution uniformity becomes difficult to control
Solution Approach 1:
The system incorporates feedback mechanisms where the positioning and distribution of each layer is monitored and adjusted based on previous layer placement. This ensures consistent spacing, thickness, and pattern alignment across multiple layers, maintaining composition stability while achieving desired aesthetic patterns
Solution Approach 2:
The composite material layers are pre-prepared with specific color patterns and veining characteristics before stacking. This preliminary preparation ensures that each layer has controlled and consistent properties, making the subsequent layering process more predictable and uniform, rather than attempting to create patterns during the stacking process itself
3Measurement precision
If computer-controlled dispensing systems are used, then material distribution precision is improved, but device complexity increases
Solution Approach 1:
Traditional manual or mechanically-controlled material dispensing is replaced with computer-controlled dispensing systems. These systems use digital control algorithms to precisely manage material flow, positioning, and distribution, achieving high measurement precision while the complexity is managed through software rather than complex mechanical linkages
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively produces quartz-based slabs with desired color patterns and veining, enhancing the aesthetic appeal of engineered stone products while maintaining the durability and resistance of quartz-based materials.
Implementation Method 1
This damp composite material is crushed and load into a container. Each container contains a different composite material. The container has rotating blades inside
Implementation Method 2
A first press roller is used to compress the multi-layered composite material. The pressure that the second press roller exerts on the fragments of composite material may be adjusted based on the final aesthetic desired in order to maintain the pattern contained inside the fragments
Implementation Method 3
The material then passes through a set of multi-pronged apparatus in order to break up and reorient the multi-layered fragments of composite material. The rotational speed of the multi-pronged apparatus may be adjusted based on the final design aesthetic desired
Implementation Method 4
The container has rotating blades inside, the rotating blades is driven by a servo motor controlled by computer, the container has a rectangular exit opening at the bottom which is less than the width of the belt that lies below it. The belt is driven by a servo motor, the speed of which is controlled by computer

AI summary
An apparatus including a first dispensing device configured to supply a first material to a conveyor belt of the main conveyor device in response to control by the computer processor, and a second dispensing device configured to supply a second material on top of the first material, while the first material is on the conveyor belt to form a combination comprised of at least the first and second materials, in response to control by the computer processor. The combination may be compressed by a first compression device in response to control by the computer processor. The compressed combination may be stirred by a first stirring device in response to control by the computer processor to form a first modified combination. The first modified combination may be compressed by a second compression device in response to control by the computer processor to form a compressed first modified combination.
