Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate communication systems are installed, then communication functionality is achieved, but device complexity and installation complexity increase
Solution Approach 1:
The patent combines communication functionality with the existing drive system by integrating a transmitter on the stator and receiver on the rotor (or vice versa). The transmitter generates magnetic fields that are detected by the receiver, enabling data transmission without separate communication hardware. This merging of drive and communication functions directly reduces device complexity and installation requirements while maintaining full communication capability between movable components.
2Adaptability or versatility
If separate communication systems are installed, then communication functionality is achieved, but additional hardware components are required
Solution Approach 1:
The patent makes the drive system components multi-functional by enabling them to perform both drive functions and communication functions. The stator electromagnets serve dual purposes: generating driving forces and transmitting communication signals. The rotor position sensors serve dual purposes: detecting position for control and receiving communication signals. This universality eliminates the need for separate communication hardware components.
Solution Approach 2:
The drive system serves itself by using its own electromagnetic fields and sensing capabilities for communication. The transmitter uses the existing magnetic field generation capability of the drive system, and the receiver uses the existing position sensing capability. This self-service approach allows the system to communicate without external communication infrastructure.
3Device complexity
If existing hardware is utilized for communication, then device complexity is reduced, but communication reliability may be compromised
Solution Approach 1:
The patent segments the communication function into distinct transmitter and receiver components that are integrated into the drive system. The transmitter is placed on the stator and the receiver on the rotor (or vice versa), creating separate functional units that work together. This segmentation allows for dedicated optimization of each component while maintaining overall system simplicity and reliability.
