Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple rotors are used on the stator to increase system capability, then productivity and versatility are improved, but the difficulty of detecting and measuring individual rotor positions and identifiers increases
Solution Approach 1:
The system assigns unique identifiers to individual rotors and uses segmented position detection zones on the stator. Each rotor is identified by its unique ID and position information is detected by specific stator regions, allowing the system to distinguish and track multiple rotors independently despite their proximity.
Solution Approach 2:
The patent introduces an intermediary identification system that mediates between the rotors and the control system. This intermediary layer provides unique rotor identifiers and position information that the main controller uses to distinguish individual rotors, effectively solving the detection difficulty without requiring direct complex sensing of each rotor.
2Adaptability or versatility
If rotors can be freely swapped or moved during switched-off state for flexibility, then adaptability is improved, but reliability deteriorates due to improper or faulty movements
Solution Approach 1:
The system employs feedback mechanisms where the main controller continuously receives position information and rotor identifiers. Before allowing rotor movement or operation, the controller verifies that the rotor is correctly positioned and identified, providing feedback that prevents improper movements and ensures reliable operation even when rotors are swapped.
Solution Approach 2:
The patent implements preliminary identification and verification actions before rotor operation. The system detects rotor identifiers and positions in advance, validates them against expected parameters, and only then permits operation. This preliminary check prevents faulty movements caused by incorrect rotor placement or identification.
3Measurement precision
If position detection systems are used to detect rotor positions, then measurement precision is improved, but device complexity increases due to additional detection components
Solution Approach 1:
The stator serves multiple functions: it acts as both the drive component for the rotors and the position detection system. The position detection zones are integrated into the stator structure, eliminating the need for separate detection components and reducing overall system complexity while maintaining precise position measurement capability.
Solution Approach 2:
The patent merges the position detection function with the existing stator structure. Instead of adding separate detection systems, the stator is designed with integrated position detection zones that work in conjunction with the rotor identifiers, combining multiple functions into a single component to reduce complexity.
