Solution Overview

Problem

Existing methods for manufacturing artificial agglomerate stone slabs struggle to efficiently produce novel veined aesthetic effects that resemble natural marble patterns, lacking reproducibility and industrial efficiency.

Innovation Solution

A method involving a first robotic device with a conical tool to create grooves in a mixture layer, followed by dispensing a second mixture into these grooves, and compacting both mixtures to form slabs with visible veined effects on the surface and thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional methods using templates or tools to create cavities/furrows are used, then veined effects can be created in artificial agglomerate slabs, but the process lacks reproducibility and industrial efficiency

Engineering Contradiction:
Improvereproducibility and industrial efficiencyVSAvoidindustrial efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent replaces traditional mechanical template-based cavity creation with a robotic system that uses a dispensing nozzle to directly deposit the second mixture into groove patterns. The robotic arm with programmable motion control substitutes manual or tool-based mechanical cavity formation, enabling precise, reproducible, and efficient veined effect creation at industrial scale.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the approach from creating physical cavities first to directly dispensing material into groove patterns. By controlling the robotic dispensing parameters (speed, deposition rate, nozzle position, mixture viscosity), the process achieves reproducible veined effects with improved industrial efficiency, transforming the manufacturing parameters rather than the fundamental process steps.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If combinations of different pigmented mixtures are separately distributed and compacted, then veined aesthetic effects can be achieved, but the process is complex and lacks reproducibility

Engineering Contradiction:
Improveaesthetic effect precisionVSAvoidprocess complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The robotic dispensing system serves multiple functions: it creates the groove patterns, deposits the second mixture with precise control, and can be programmed to reproduce identical veined patterns across different slabs. This single multi-functional system replaces multiple separate operations (template application, cavity creation, manual filling), reducing overall process complexity while maintaining aesthetic precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The robotic system incorporates feedback control through programmable motion paths and deposition parameters. The system can be programmed with precise trajectories for groove creation and filling, ensuring reproducible veined effects. Sensors and control systems monitor and adjust parameters during the process to maintain consistent aesthetic quality across production batches.

Inventive Principle:
Principle #23Feedback
