Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an independent coolant pipeline is used, then coolant flow rate can be controlled, but the structure becomes complicated and installation space is occupied
Solution Approach 1:
The patent combines the coolant supply function with the lifting rod assembly by integrating a pipe through the lifting rod. This merging eliminates the need for an independent coolant pipeline, simplifying the overall structure while maintaining coolant supply capability to the workpiece area.
Solution Approach 2:
The lifting rod assembly is given multiple functions: it serves both as a mechanical lifting component and as a coolant delivery system. The pipe integrated into the lifting rod allows coolant to be supplied through the same structural element, reducing the number of separate components needed.
2Reliability
If the coolant pipeline location is changed to target small workpieces, then coolant can reach the workpiece, but the operation becomes inconvenient
Solution Approach 1:
The lifting rod assembly is made movable, allowing dynamic adjustment of the coolant delivery position. By moving the lifting rod to different locations, the coolant can be precisely targeted at various workpiece positions without requiring manual repositioning of fixed pipelines, thus maintaining both accuracy and operational convenience.
Solution Approach 2:
The lifting rod assembly acts as an intermediary carrier for the coolant pipe. Instead of directly positioning fixed pipelines at workpiece locations, the lifting rod serves as a mobile platform that brings the coolant supply to the required position, simplifying the operation of targeting small workpieces.
3Ease of operation
If coolant flow rate is controlled without pressurization, then flow rate can be adjusted, but coolant pressurization capability is lost
Solution Approach 1:
The patent incorporates a pressurizing device within the pipe system to provide hydraulic pressurization of the coolant. This allows the coolant to be delivered under pressure to improve swarf removal efficiency and cooling effectiveness, while still maintaining controllable flow rate through the integrated design.
4Device complexity
If coolant is not precisely targeted at the workpiece, then the system is simpler, but coolant is wasted
Solution Approach 1:
The movable lifting rod assembly enables dynamic positioning of the coolant delivery point, allowing precise targeting of coolant at the workpiece area. This dynamic adjustment ensures coolant is applied only where needed, reducing waste while maintaining system simplicity through the integrated pipe design within the lifting rod.
