Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote driving mode switching is not implemented, then system complexity is reduced, but adaptability to complex road and network conditions deteriorates
Solution Approach 1:
The patent implements dynamic mode switching between HRC and MRC based on real-time network conditions and road situations. The system transitions from a static single-mode approach to a dynamic multi-mode system that adapts to changing conditions, resolving the contradiction between adaptability and complexity by introducing controlled dynamism through automated switching mechanisms.
Solution Approach 2:
The patent changes the operational parameters of the remote driving system by switching between different control modes (HRC and MRC) based on network quality and road conditions. This parameter change approach allows the system to optimize performance for different scenarios without requiring complete system redesign, balancing adaptability gains against complexity increases.
2Ease of operation
If manual mode switching is required, then system complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service through automated mode switching where the system independently monitors network conditions and road situations to determine optimal control modes. This eliminates the need for manual operator intervention in mode selection, significantly improving ease of operation while the automated decision-making algorithms manage the underlying complexity.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring network quality metrics and road condition data to automatically adjust control modes. This closed-loop feedback approach enables intuitive, context-aware mode switching that appears simple to operators while managing complex decision-making processes internally.
3Adaptability or versatility
If multiple PDU session parameters are maintained for different modes, then adaptability improves, but loss of information increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple PDU session parameters for different control modes before switching is needed. This allows the system to maintain ready-to-use parameter sets for both HRC and MRC modes, enabling rapid mode transitions without information loss or reconfiguration delays during actual switching operations.
Solution Approach 2:
The patent segments the parameter management by maintaining separate PDU session parameter sets for different control modes. This segmentation allows each mode to have its optimized parameters independently configured and stored, facilitating clean transitions between modes while preserving all necessary configuration information for each specific operating condition.
