Solution Overview

Problem

Existing squaring machines for slab-shaped elements, such as ceramic or natural stone slabs, face inefficiencies in positioning and equipping abrasive tools, leading to significant idle time and non-productive periods due to manual or sequential control methods.

Innovation Solution

A squaring machine equipped with a frame and moving plane that includes two groups of individually movable abrasive tools, each with a dedicated optical group and reference body for precise positioning, allowing for simultaneous and independent setup of all tools, reducing idle time by about 80% through real-time monitoring and correction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single optical group is used for all abrasive tools, then device complexity is reduced, but positioning precision and productivity deteriorate due to sequential control requirements

Engineering Contradiction:
Improveoptical control system complexityVSAvoidmachine productivity
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent divides the optical control system into multiple independent optical groups, with each optical group dedicated to controlling a specific abrasive tool. This segmentation allows parallel operation of all abrasive tools simultaneously, eliminating the sequential control bottleneck while maintaining individual positioning precision for each tool.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a vertical dimension to the control architecture by positioning optical groups at different heights and locations, each overlooking its specific abrasive tool. This spatial distribution enables independent simultaneous control of multiple tools without mechanical interference, resolving the contradiction between system simplicity and parallel operation capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If manual positioning methods are used for abrasive tools, then device complexity is reduced, but positioning precision and productivity deteriorate due to time-consuming adjustments

Engineering Contradiction:
Improvepositioning system complexityVSAvoidsetup time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical positioning with automated optical detection and control systems. Each optical group captures images of reference bodies and abrasive tool positions, and the control unit automatically calculates and adjusts tool positions based on image analysis, eliminating time-consuming manual adjustments while achieving high positioning precision.

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

Solution Approach 2:

The system enables self-positioning of abrasive tools through automated optical feedback. The optical groups continuously monitor tool positions relative to reference bodies, and the control unit automatically makes adjustments without operator intervention, significantly reducing setup time while maintaining simplicity through standardized procedures.

Inventive Principle:
Principle #25Self-service

3Device complexity

If sequential control of abrasive tools is used, then device complexity is reduced, but positioning precision deteriorates due to cumulative errors

Engineering Contradiction:
Improvecontrol system complexityVSAvoidpositioning precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent segments the control system into independent optical groups, each responsible for a specific abrasive tool. This independence eliminates cumulative errors from sequential control, as each tool's position is determined by its own optical reference system rather than being dependent on previous tool positions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses optical copying of reference body positions through image capture and analysis. Each optical group creates a visual copy of the reference body and abrasive tool positions, allowing the control unit to calculate precise relative positions without physical contact or cumulative mechanical errors, thereby achieving high positioning precision.

Inventive Principle:
Principle #26Copying
