Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tool systems lack an effective method to monitor and maintain the optimal level of machining fluid, leading to potential disruptions in machining quality due to insufficient fluid supply.
Innovation Solution
A machine tool system equipped with a tank unit, ultrasonic sensor, pump, and controller that measures the machining fluid level using ultrasonic sensors and performs liquid-level analysis to determine when the fluid is low, triggering the pump to stop and alerting the operator, while also monitoring temperature and current usage for chip removal and fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional machine tool systems operate without automated fluid level monitoring, then device complexity is reduced, but machining quality deteriorates due to insufficient fluid supply
Solution Approach 1:
The ultrasonic sensor continuously measures the machining fluid level in advance before it drops to critical levels. The controller receives the distance signal and performs liquid-level analysis to determine when fluid is low, stopping the pump proactively before insufficient fluid can affect machining quality. This preliminary detection and action prevent quality deterioration.
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where the ultrasonic sensor continuously monitors fluid level and sends distance signals to the controller. The controller analyzes these signals and provides feedback by controlling the pump operation - stopping it when fluid is low and resuming when fluid is sufficient. This feedback loop ensures machining quality is maintained through automated regulation.
2Reliability
If automated ultrasonic sensing and controller systems are added to monitor fluid levels, then machining quality is improved through stable fluid supply, but device complexity increases
Solution Approach 1:
The machine tool system serves itself by automatically monitoring its own machining fluid level using the ultrasonic sensor and autonomously controlling the pump through the controller. The system detects low fluid levels and stops the pump without external intervention, then resumes operation when fluid is replenished. This self-service capability enhances reliability while the modular design keeps complexity manageable.
3Productivity
If the pump operates continuously without level monitoring, then productivity is maintained, but harmful effects occur due to pump operation with insufficient fluid
Solution Approach 1:
The ultrasonic sensor and controller implement preliminary anti-action by detecting low fluid levels before the pump can operate harmfully. When the sensor measures that fluid level is below the safe threshold, the controller immediately stops the pump, preventing empty operation and potential damage. This preemptive measure eliminates harmful effects while allowing continuous productivity when fluid levels are adequate.
