Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slip ring system is used for data transmission, then data can be transmitted from rotating to stationary sections, but the data transmission rate is limited and reliability deteriorates due to wear and contamination
Solution Approach 1:
The patent replaces the mechanical slip ring system with a wireless radio-based transmission system. Radio transmitters on the rotating section communicate with radio receivers on the stationary section through electromagnetic waves, eliminating mechanical sliding contacts and their associated wear and contamination problems. This substitution enables both high reliability and high data transmission rates simultaneously.
2Productivity
If the main radiation direction of radio transmitters is fixed, then the system is simpler, but data transmission can only occur at discrete times when the transmitter aligns with the receiver, severely limiting the data transmission rate
Solution Approach 1:
The patent makes the main radiation direction of radio transmitters dynamically adjustable rather than fixed. The transmitters can change their beam direction in real-time to track and maintain alignment with receivers as the rotating section moves. This dynamic adjustment capability ensures continuous data transmission and achieves high data transmission rates, while the complexity is managed through coordinated control systems.
3Reliability
If multiple transmission pairs are formed with steerable main radiation directions, then continuous data transmission is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the transmission system into multiple independent transmission pairs, each consisting of a radio transmitter and a radio receiver. By segmenting the overall transmission task into multiple parallel channels, the system achieves continuous data transmission through redundancy and load distribution. The complexity of steering multiple transmitters is managed by coordinating their operations across different spatial and temporal dimensions.
