Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for crankshaft machining, then device complexity is reduced, but productivity is low and manufacturing precision is poor
Solution Approach 1:
The patent employs a universal fixture system with adjustable positioning mechanisms that can accommodate different types of crankshafts. The milling device integrates multiple functions including positioning, clamping, and multi-axis milling operations into a single system, eliminating the need for dedicated fixtures for each crankshaft type while maintaining high productivity and precision
Solution Approach 2:
The patent replaces manual mechanical operation with computer numerical control (CNC) systems. The CNC controller automates the milling spindle movements along X, Y, and Z axes, and controls the workpiece rotation, substituting manual labor with automated mechanical systems to achieve high productivity and consistent manufacturing precision
2Adaptability or versatility
If dedicated fixtures are used for each crankshaft type, then manufacturing precision is ensured, but device complexity increases and adaptability decreases
Solution Approach 1:
The patent employs a universal fixture system with adjustable positioning mechanisms that can accommodate different types of crankshafts. The milling device integrates multiple functions including positioning, clamping, and multi-axis milling operations into a single system, eliminating the need for dedicated fixtures for each crankshaft type while maintaining high productivity and precision
Solution Approach 2:
The patent uses dynamically adjustable positioning mechanisms that can be reconfigured for different crankshaft types. The fixture system includes adjustable supports and clamps that can be positioned along the length of the crankshaft, allowing the same device to adapt to various geometries and sizes without requiring dedicated fixtures for each type
3Productivity
If continuous cutting is not achieved, then device complexity is reduced, but productivity decreases due to empty feeds
Solution Approach 1:
The patent achieves continuous cutting by coordinating the rotation of the crankshaft with the movement of the milling spindle. The CNC controller synchronizes the workpiece rotation speed with the spindle feed rate, ensuring that the cutting tool continuously engages with the workpiece material without interruption or empty feeds, thereby maximizing productivity
Solution Approach 2:
The patent incorporates feedback mechanisms through the CNC control system that monitors the position and movement of the milling spindle and the rotation of the workpiece. This feedback allows real-time adjustment of cutting parameters to maintain continuous cutting engagement, optimizing productivity while managing device complexity through intelligent control
