Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a traditional coolant discharger system is used to remove chips from workpieces, then chip removal is achieved, but large amounts of coolant are required resulting in high power consumption and environmental impact
Solution Approach 1:
The patent applies local quality by directing coolant through a nozzle positioned within the workpiece bore to target specific localized areas where chips accumulate, rather than spraying coolant broadly across the entire workpiece. This focused application reduces overall coolant consumption while maintaining effective chip removal capability in the critical machining zones.
Solution Approach 2:
The patent implements dynamics by making the nozzle movable along the rotation axis, allowing the coolant discharge position to be dynamically adjusted during machining operations. This enables the system to adapt to different workpiece geometries and machining stages, optimizing coolant delivery efficiency and reducing waste without compromising chip removal performance.
2Manufacturing precision
If traditional coolant discharger systems are used, then cooling and lubrication are provided, but the systems fail to effectively target specific areas for cooling and lubrication
Solution Approach 1:
The patent applies local quality by positioning the nozzle inside the workpiece bore to deliver coolant precisely to specific areas requiring cooling and lubrication, such as the tool-workpiece interface and chip flow paths. This localized delivery enhances manufacturing precision by ensuring critical zones receive adequate cooling without wasting coolant on already-cooled or non-critical areas.
Solution Approach 2:
The patent uses the workpiece bore itself as an intermediary structure to guide and position the nozzle for precise coolant delivery. The bore serves as a natural conduit that directs coolant flow to specific target areas, improving both cooling accuracy and coolant distribution efficiency simultaneously.
3Loss of substance
If a movable nozzle design is implemented along the rotation axis, then coolant application can be focused on specific areas, but device complexity increases
Solution Approach 1:
The patent implements dynamics by providing a movable nozzle that can adjust its position along the rotation axis, enabling focused coolant application to specific workpiece areas. The movable design allows the system to adapt to varying machining requirements and workpiece geometries, reducing coolant waste through precise targeting while maintaining manageable complexity through straightforward linear movement along the axis.

AI summary
A coolant discharger includes a rotator, a fluid passage, and a nozzle. The rotator is rotatable about a rotation axis together with a workpiece and has a through hole extending along the rotation axis. The fluid passage is provided in the through hole to supply a coolant toward the workpiece. The nozzle is connected to the rotator to be connected to the fluid passage to discharge the coolant from the nozzle toward the workpiece in a discharging direction away from the rotation axis. At least a part of the nozzle is movable along the rotation axis.
