Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional machining processes are used for aluminum alloy wheels, then the manufacturing process is simple, but end face deformation and clamping deformation occur causing end face run-out
Solution Approach 1:
The device performs preliminary positioning and detection before final machining. The lifting rack I and guide posts I position the wheel in advance, and the dial indicator detects end face run-out before correction, allowing preventive adjustment rather than post-processing repair
Solution Approach 2:
The profiling pressure blocks act as intermediaries between the detection system and the wheel end face. They transfer the correction force precisely to the deformed areas identified by the dial indicator, enabling controlled deformation correction without direct manual intervention
2Reliability
If end face run-out is not corrected, then the manufacturing process is fast, but wheel vibration occurs during driving affecting safety and comfort
Solution Approach 1:
The device integrates detection and correction in a continuous on-line process. The lifting rack I positions the wheel, dial indicator detects run-out, and profiling pressure blocks correct deformation all in one continuous operation without removing the wheel from the production line, eliminating idle time
Solution Approach 2:
The system automatically detects and corrects end face deformation without external intervention. The servo electric cylinders automatically adjust the profiling pressure blocks based on dial indicator readings, enabling the system to self-correct deformation and ensure driving safety autonomously
3Productivity
If manual detection and correction methods are used, then the equipment cost is low, but automation degree is low and efficiency is reduced
Solution Approach 1:
The lifting rack I serves multiple functions: it positions the wheel for detection, supports the wheel during measurement, and facilitates the correction process. The guide posts I and guide sleeves I provide both positioning and guidance for the profiling pressure blocks, reducing the need for separate dedicated components
Solution Approach 2:
The dial indicator provides real-time feedback on end face run-out to the control system. This feedback enables the servo electric cylinders to automatically adjust the profiling pressure blocks until the run-out is corrected, creating a closed-loop control system that improves precision without requiring complex manual measurement and adjustment procedures
