Solution Overview

Problem

Existing machine tools for processing stone materials are inefficient, requiring manual handling and transfer between stations, leading to long processing times, high skill requirements, and a risk of waste or non-conforming products due to the lack of automated slab transfer and simultaneous multi-process capabilities.

Innovation Solution

A modular machine tool system with a support surface that moves stepwise along a longitudinal direction, allowing products to be processed in adjacent working areas without manual transfer, featuring toolholder heads that perform specific processes and automatic movement between stations, reducing the need for manual intervention and enhancing precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple independent workstations are provided for simultaneous stone-working processes, then productivity is improved, but device complexity increases due to multiple separate stations and manual transfer requirements

Engineering Contradiction:
Improveprocessing throughputVSAvoidsystem structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple independent workstations into a single integrated machine by providing a single support table that can be divided into multiple working areas, with toolholder heads that can move between these areas, eliminating the need for separate stations and manual transfers while maintaining simultaneous processing capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The toolholder heads are designed with multi-functionality, capable of performing different stone-working processes (drilling, scratching, polishing, honing, brushing, calibrating) at different working areas, allowing a single device to replace multiple specialized stations

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

2Ease of manufacture

If manual handling and transfer of slabs between stations is required, then ease of manufacture is improved, but loss of time increases due to manual intervention and repositioning

Engineering Contradiction:
Improvemachine simplicityVSAvoidprocessing cycle time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The machine performs self-service through automated functions including the support table's ability to be divided and reconfigured, toolholder heads that automatically move between working areas, and centralized control that manages the entire processing sequence without manual intervention, thereby eliminating time losses associated with manual handling

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If distinct stone-working processes are performed on the entire length of the block, then manufacturing precision is improved, but loss of time increases due to repeated manual transfer and recentering operations

Engineering Contradiction:
Improveprocessing accuracyVSAvoidoverall processing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent ensures continuity of useful action by allowing the support table to remain in a fixed position throughout the entire processing sequence, with toolholder heads moving automatically between working areas to perform multiple processes continuously on the same block without interruption or repositioning, thereby maintaining precision while eliminating time losses

Inventive Principle:
Principle #20Continuity of useful action

4Manufacturing precision

If high-precision processing is required within predetermined tolerances, then manufacturing precision is improved, but ease of operation worsens due to high skill requirements for manual transfer and head centering

Engineering Contradiction:
Improveprocessing toleranceVSAvoidoperator skill requirement
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The machine incorporates feedback through centralized control that automatically manages the positions of the support table and toolholder heads, monitoring and adjusting their locations to maintain predetermined tolerances throughout the processing sequence, thereby achieving high precision while eliminating the need for operator skill in manual positioning and centering

Inventive Principle:
Principle #23Feedback
