Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed internal cooling system is used, then the structure is simple, but the cooling efficiency varies in different contact conditions and some areas may not be cooled
Solution Approach 1:
The patent applies the dynamics principle by making the cooling system adjustable through a control unit that regulates the opening angles of nozzle groups based on real-time detection of tool-workpiece contact states. This transforms the fixed cooling system into a dynamic one that adapts to varying cutting positions and contact conditions, ensuring optimal cooling efficiency throughout the turning process of curved surface components.
Solution Approach 2:
The patent implements parameter changes by varying the opening angles of different nozzle groups according to the detected contact states. The control unit adjusts the flow direction and distribution of the cooling medium by changing the opening angles dynamically, allowing the system to optimize cooling parameters for different cutting positions and maintain reliable cooling efficiency.
2Device complexity
If the cooling medium action direction is constant, then the system is simple, but the cooling medium becomes ineffective when part of the curved surface component is in turning state and generates additional impact force
Solution Approach 1:
The patent applies dynamics by enabling the nozzle groups to adjust their opening angles dynamically based on the turning state detection. This allows the cooling medium delivery direction to change adaptively, ensuring the cooling medium remains effective during turning operations and reduces negative impact forces that would otherwise hinder chip breaking efficiency.
Solution Approach 2:
The system changes the delivery parameters of the cooling medium by adjusting the opening angles of nozzle groups in response to detected turning states. This parameter adjustment optimizes the flow direction and intensity of the cooling medium, improving chip breaking efficiency while eliminating the negative effects of constant direction delivery.
3Ease of manufacture
If traditional cooling methods are used, then the implementation is simple, but the tool wear is severe and service life is shortened
Solution Approach 1:
The patent replaces traditional mechanical cooling delivery systems with a detection-based control system. Sensors detect the tool-workpiece contact states and feed this information to a control unit, which then adjusts the nozzle opening angles accordingly. This substitution of mechanical adjustment with automated detection and control significantly improves tool cooling effectiveness and extends tool service life while maintaining ease of implementation.
Solution Approach 2:
The patent implements feedback by using detection units to monitor the contact states between the tool and workpiece in real-time, and using this feedback information to dynamically adjust the cooling medium delivery through the nozzle groups. This closed-loop feedback system ensures optimal cooling is delivered to the tool, reducing wear and extending service life.
