Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unmanned vehicles operate independently without information sharing, then each vehicle maintains operational independence, but driving control efficiency is low
Solution Approach 1:
The patent implements a feedback mechanism where unmanned vehicles send travel information (including position, speed, acceleration, and safety status) to a server, which then pushes relevant information to other vehicles. This closed-loop information feedback system enables real-time awareness of surrounding vehicles' states, improving driving control efficiency through adaptive decision-making while maintaining operational independence.
Solution Approach 2:
The patent introduces a server as an intermediary that collects, processes, and distributes travel information between unmanned vehicles. This intermediary system resolves the contradiction by enabling efficient information sharing without requiring direct vehicle-to-vehicle communication protocols, thus maintaining operational independence while improving overall system efficiency through centralized information management.
2Productivity
If unmanned vehicles share all travel information in real-time, then driving control efficiency improves, but system complexity increases
Solution Approach 1:
The patent extracts only the essential travel information parameters (position, speed, acceleration, safety status) needed for driving control decisions and transmits them to the server. By selecting and transmitting only critical data rather than all possible vehicle parameters, the system achieves improved driving control efficiency while minimizing communication overhead and system complexity.
Solution Approach 2:
The patent changes the parameter representation by encoding travel information into standardized data structures with specific formats and protocols. This parameter standardization enables efficient information processing and sharing while reducing system complexity through uniform data handling, making the information sharing system more manageable and scalable.
3Productivity
If unmanned vehicles use centralized server for information sharing, then information sharing efficiency improves, but communication overhead increases
Solution Approach 1:
The patent implements periodic information updates where vehicles send their travel status at regular intervals rather than continuously. This periodic communication approach maintains information sharing efficiency by providing timely updates for driving control decisions while reducing communication overhead and latency compared to continuous real-time streaming, thus minimizing communication time loss.
