Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conveyor is used to transfer the radical unit, then the transfer process is continuous, but the configuration of the facility becomes complicated and individual position and speed of the object cannot be controlled
Solution Approach 1:
The patent replaces the conventional mechanical conveyor system with a linear motor system that uses electromagnetic fields to propel loading parts. This substitution eliminates the need for complex mechanical transmission mechanisms while enabling precise control of position and speed through electronic control of the linear motor, directly resolving the contradiction between control precision and system complexity
Solution Approach 2:
The patent changes the control parameters from fixed mechanical conveyor speed to variable electronic control signals for the linear motor. By adjusting the frequency and amplitude of the control signals, the system can dynamically control the speed and position of loading parts, achieving individual object control without mechanical complexity
2Productivity
If a conveyor is used to transfer the radical unit, then the transfer process is continuous, but the supply speed is limited
Solution Approach 1:
The linear motor system replaces the mechanical conveyor, enabling higher supply speeds through direct electromagnetic propulsion without mechanical inertia limitations. The system can rapidly accelerate and decelerate loading parts, significantly increasing the supply speed of objects while maintaining a simpler facility configuration
Solution Approach 2:
The patent implements dynamic speed control where the loading parts can be accelerated and decelerated at different rates depending on the process requirements. The linear motor enables rapid changes in velocity, allowing the system to optimize supply speed dynamically rather than operating at a fixed conveyor speed
