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 delay becomes unstable and driving safety is compromised
Solution Approach 1:
The patent implements dynamic wireless channel selection by continuously monitoring communication delays across multiple candidate channels and automatically switching to the optimal channel. The remote control terminal dynamically adjusts the wireless communication path based on real-time network conditions, transforming a static single-channel system into a dynamic multi-channel system that adapts to changing environmental factors, thereby ensuring stable communication delay without significantly increasing system complexity
Solution Approach 2:
The patent changes the parameter of wireless channel selection from fixed to variable by introducing delay monitoring and comparison mechanisms. The system monitors communication delay parameters across multiple channels and selects the channel with the most favorable parameter (shortest delay), thereby improving reliability while maintaining manageable device complexity through automated parameter optimization
2Loss of time
If multiple candidate wireless networks are monitored and selected based on geographic location, then the communication delay is reduced, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a database of candidate wireless channels organized by geographic location before remote control operations begin. When the vehicle enters a specific geographic area, the system quickly retrieves pre-configured candidate channels for that location, avoiding the need to scan and evaluate all possible channels from scratch. This preliminary preparation significantly reduces communication delay while keeping the real-time selection process simple
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a wireless channel management module that acts as a mediator between the vehicle and multiple wireless networks. This intermediary automatically monitors delays, compares channels, and selects the optimal connection, shielding the user from the complexity of managing multiple networks while achieving low-latency communication
