Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable-based data transmission is used between rotor and stator, then reliable data transmission is achieved, but large space occupation and inconvenient integration occur
Solution Approach 1:
The patent replaces the mechanical cable-based transmission system with a wireless transmission system using electromagnetic waves or optical waves. The transceiver on the rotor and transmitter on the stator establish wireless bidirectional communication, eliminating physical cables and thereby reducing space occupation while maintaining transmission reliability through protocol-level error handling and retransmission mechanisms.
Solution Approach 2:
The patent introduces wireless electromagnetic waves or optical waves as an intermediary medium to transmit data between the rotor and stator. This intermediary replaces the direct physical connection of cables, allowing data to pass through the air gap or optical path without requiring physical contact, thus solving the space occupation problem while preserving communication reliability.
2Productivity
If cable-based data transmission is used between rotor and stator, then data transmission function is achieved, but integration convenience deteriorates
Solution Approach 1:
The patent substitutes the complex mechanical cable routing and connection system with a wireless transmission system. The transceiver and transmitter components require minimal installation infrastructure compared to cable management, significantly improving integration convenience while maintaining or enhancing data transmission efficiency through direct wireless links.
Solution Approach 2:
The patent extracts the data transmission function from the physical cable infrastructure and implements it through wireless electromagnetic or optical waves. This extraction eliminates the need for cable routing, connectors, and associated mechanical components, thereby simplifying the integration process while preserving the core data transmission functionality.
3Volume of moving object
If wireless bidirectional transmission is implemented, then space occupation is reduced, but transmission system complexity increases
Solution Approach 1:
The patent designs the transceiver and transmitter as multi-functional components that handle both data transmission and reception, as well as signal processing and error correction. This universality consolidates multiple functions into single components, reducing the overall number of parts needed and offsetting the increased complexity of wireless communication protocols through functional integration.
Solution Approach 2:
The patent implements bidirectional transmission by having the rotor's transceiver and stator's transmitter replicate each other's communication capabilities. Each side has equivalent functional copies of the transmission and reception mechanisms, allowing symmetric wireless communication without requiring complex asymmetric routing or additional intermediary components, thereby managing system complexity through symmetry and replication.
