Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fixed network wireless channel is used for remote control, then the device complexity is reduced, but the communication stability and response time deteriorate due to network instability
Solution Approach 1:
The patent combines multiple wireless network channels (4G, 5G, Wi-Fi, satellite) into a unified remote control system. The server selectively switches between different network channels based on signal quality and availability, ensuring stable communication while maintaining manageable system complexity through centralized control logic.
Solution Approach 2:
The system dynamically changes network parameters by selecting different wireless channels based on real-time conditions. The server monitors signal strength, latency, and network availability, then switches between network types (e.g., from 4G to satellite) to optimize communication reliability under varying environmental conditions.
2Ease of operation
If a single wireless network channel is used, then the system is simpler to operate, but the response time of control instructions deteriorates due to network delays
Solution Approach 1:
The system performs preliminary actions by pre-establishing multiple wireless network connections and continuously monitoring their status before remote control is needed. When the vehicle enters extreme conditions, the server already has ready-to-use alternative channels, eliminating the time delay that would occur if network switching had to happen during critical moments.
Solution Approach 2:
The remote control system transitions from a static single-channel approach to a dynamic multi-channel system. The server continuously adjusts the active network channel based on real-time signal quality, automatically selecting the fastest available path for control instruction transmission without requiring manual intervention.
3Reliability
If multiple wireless networks are used for control instruction transmission, then the communication reliability improves through redundant backup, but the device complexity increases
Solution Approach 1:
The server acts as an intermediary that manages the complexity of multiple wireless networks. Instead of the vehicle directly handling multiple network connections, the server consolidates network management functions, selecting and switching between channels based on predefined criteria. This intermediary approach provides redundant communication paths while keeping the vehicle's onboard system relatively simple.
4Adaptability or versatility
If multiple wireless networks are deployed, then the system can adapt to different network environments, but the difficulty of detecting and measuring optimal channels increases
Solution Approach 1:
The system implements feedback mechanisms where the server continuously monitors the performance of each wireless network channel (signal strength, latency, packet loss) and uses this information to make informed switching decisions. The vehicle also provides feedback on its status and received instructions, allowing the server to optimize channel selection based on real-time performance data rather than guessing which channel is best.
