Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication frequency is increased for all collision detection devices, then collision detection reliability is improved, but communication channel congestion and interference worsen
Solution Approach 1:
The patent applies local quality by assigning different communication frequencies to different collision detection devices based on their individual priority levels. High-priority devices (e.g., pedestrians, cyclists) communicate on frequencies optimized for their safety critical needs, while low-priority devices (e.g., stationary objects) use different frequencies. This localized frequency allocation ensures that each device receives appropriate communication resources without causing universal congestion, thereby maintaining high collision detection reliability while preventing system-wide communication interference.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting communication frequency parameters based on device priority. The system modifies the frequency parameter (not just communication rate) to allocate spectrum resources efficiently. High-priority devices are assigned frequencies with better propagation characteristics or less interference, while low-priority devices use other frequencies. This parameter-based differentiation resolves the contradiction by allowing reliable communication for critical devices without overwhelming the entire communication channel.
2Object-generated harmful factors
If communication frequency is decreased for low-priority devices, then communication channel congestion is reduced, but collision detection coverage may be compromised
Solution Approach 1:
The patent applies local quality by implementing differentiated frequency allocation where low-priority devices (such as stationary objects or non-critical mobile devices) are assigned specific frequencies distinct from high-priority devices. This localized frequency reduction for low-priority traffic reduces overall channel congestion without compromising the detection coverage for critical devices. The system maintains adequate coverage by ensuring that frequency reduction for low-priority devices does not eliminate their communication capability entirely,而是 optimizes the distribution of communication resources across different priority levels.
3Productivity
If priority-based frequency allocation is implemented, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing priority levels and corresponding frequency allocations for different types of collision detection devices before actual communication occurs. The system pre-defines which device categories (pedestrians, cyclists, vehicles, stationary objects) receive which frequency bands based on their collision risk profiles. This preliminary configuration simplifies real-time operations, as devices can directly use their pre-assigned frequencies without complex dynamic negotiations, thereby improving communication efficiency while keeping system complexity manageable through upfront planning.
