Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the dielectric working fluid temperature is regulated to room temperature, then the workpiece temperature matches the environment, but the body temperature discrepancy causes thermal deformation and reduces machining accuracy
Solution Approach 1:
The system continuously measures the body temperature of the wire electric discharge machine body using a temperature sensor, and uses this feedback to dynamically adjust the dielectric working fluid temperature through the temperature regulator, ensuring the working fluid temperature matches the body temperature and eliminating thermal deformation
Solution Approach 2:
The system changes the temperature parameter of the dielectric working fluid from a fixed room temperature setting to a dynamically adjusted temperature that matches the body temperature, thereby resolving the thermal deformation issue caused by temperature discrepancy
2Manufacturing precision
If a temperature control system is added to match working fluid temperature with body temperature, then machining accuracy is maintained, but device complexity increases
Solution Approach 1:
The temperature control system automatically regulates itself by using the temperature sensor to measure the body temperature and the temperature regulator to adjust the working fluid temperature accordingly, without requiring manual intervention or complex external control mechanisms
