Solution Overview

Problem

Imaging devices struggle to capture suitable images of machining machines due to unsuitable imaging environments, often obstructed by coolants or other factors.

Innovation Solution

An imaging environment adjustment device with a trigger detection unit, setting table, and imaging environment adjustment unit that detects triggers and adjusts the environment by controlling settings such as coolant flow and spindle movement to optimize imaging conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an imaging device captures an image of a machining machine, then the imaging function is performed, but the imaging quality deteriorates due to unsuitable environment (coolant obstruction, etc.)

Engineering Contradiction:
Improveimaging functionVSAvoidimaging quality
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by detecting triggers (such as imaging requests or environmental conditions) and adjusting the imaging environment before the actual imaging occurs. The control unit modifies coolant flow, spindle position, or other environmental factors in advance to ensure optimal imaging conditions are established prior to image capture, thereby resolving the contradiction between maintaining imaging function and improving imaging quality.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If the imaging environment is adjusted to optimize image capture, then imaging quality improves, but the machining process may be interrupted or slowed down

Engineering Contradiction:
Improveimaging qualityVSAvoidmachining efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system implements periodic action by adjusting the imaging environment only at specific intervals or under specific conditions (trigger events) rather than continuously. The control unit monitors for trigger conditions (such as imaging requests, tool changes, or specific machining stages) and only then modifies environmental parameters, allowing the machining process to proceed uninterrupted during normal operation while ensuring optimal imaging conditions when needed.

Inventive Principle:
Principle #19Periodic action

3Measurement precision

If multiple environment settings are adjusted simultaneously for optimal imaging, then imaging quality improves, but the system complexity increases

Engineering Contradiction:
Improveimaging qualityVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system employs feedback mechanisms by monitoring environmental parameters (such as coolant flow status, spindle position, lighting conditions) and using this information to automatically adjust settings through the control unit. The trigger detection unit and environmental sensors provide continuous feedback about the current state, enabling the control unit to make intelligent, automated decisions about which environment settings to adjust and to what extent, thereby improving imaging quality without requiring complex manual coordination of multiple parameters.

Inventive Principle:
Principle #23Feedback
