Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration is used to record positions of stator modules, then the system can be set up, but the process is very time-consuming and error-prone
Solution Approach 1:
The patent replaces the manual mechanical configuration process with an automated magnetic field-based detection system. Magnetic field sensors automatically detect the positions and orientations of stator modules by sensing magnetic fields from conductor strips, eliminating the need for manual recording and processing of position data.
Solution Approach 2:
The system performs self-configuration by automatically detecting its own component positions. The control unit sends control signals to energize conductor strips, receives detection signals from magnetic field sensors, and autonomously determines the topography of stator modules without external manual intervention.
2Ease of manufacture
If manual configuration is used for large planar drive systems with many stator modules, then the system can be assembled, but errors easily occur when detecting and storing positions
Solution Approach 1:
The patent replaces error-prone manual detection and recording with automated magnetic field sensing. The magnetic field sensors objectively detect positions and orientations, and the control unit automatically processes this data to generate accurate topography information, eliminating human errors in detection and data storage.
Solution Approach 2:
The system uses feedback from magnetic field sensors to continuously verify and correct position information. The control unit receives detection signals, evaluates them to determine neighborhood relationships, and uses this feedback to build an accurate reference table of stator module positions and orientations.
3Productivity
If automated configuration using magnetic field sensors is implemented, then configuration time is reduced, but the system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it energizes conductor strips, receives detection signals from magnetic field sensors, processes the signals to determine positions and orientations, and generates the reference table. This multi-functionality consolidates the automated configuration process into a single control unit, managing complexity through functional integration.
Solution Approach 2:
The system performs preliminary detection and evaluation of magnetic fields during the configuration phase to automatically establish the topography of stator modules. This preliminary automated action creates a reference table that enables subsequent automated control operations, eliminating the need for repeated manual configuration.
