Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engineered stone slabs lack the complex look and texture of quarried stone slabs, and their appearance is not easily reproducible, limiting their aesthetic appeal and versatility.
Innovation Solution
A system and process for forming synthetic molded slabs by vertically dispensing differently pigmented particulate mineral mixes into a mold according to a predefined pattern, followed by horizontal compaction and curing, to create slabs with repeatable veining patterns that emulate quarried stone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engineered stone slabs are formed from man-made combination of materials, then stain-resistant and heat-resistant properties are improved, but the complex look and texture of quarried stone slabs deteriorates
Solution Approach 1:
The patent applies local quality by using differently pigmented particulate mineral mixes in specific vertical layers within the mold. Each layer contains distinct pigment combinations that create localized veining patterns and striations, emulating the natural variation found in quarried stone while maintaining the engineered material's durability properties
Solution Approach 2:
The patent uses composite materials by combining particulate mineral material with resin binder to create an engineered stone that maintains stain and heat resistance. The composite structure incorporates multiple pigmented mixes in vertical layers, creating a material that combines the durability of engineered stone with the aesthetic complexity of natural stone
2Manufacturing precision
If engineered stone slabs are manufactured with predefined patterns, then manufacturing precision is improved, but the appearance reproducibility deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the slab into vertically stacked layers, each containing differently pigmented particulate mineral mixes. This segmentation allows each layer to be independently controlled during dispensing, creating reproducible veining patterns while maintaining natural-looking variation across different slabs
Solution Approach 2:
The patent uses parameter changes by varying pigment combinations, particle sizes, and layer thicknesses in the vertical dispensing process. These controlled parameter variations create consistent veining patterns that are reproducible across slabs while maintaining the appearance of natural stone variation
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 method produces slabs with consistent, complex striations and veining patterns that resemble quarried stone, offering improved aesthetic variety and versatility in applications like countertops and floors.
Implementation Method 1
Engineered stone is typically a combination of particulate mineral material and a binder, such as a polymer resin
Implementation Method 2
The mold is then shifted to a horizontally oriented position for subsequent compression molding and curing operations
