Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple autonomous sensors and high-performance control units are mounted on each vehicle to achieve precise collision avoidance control, then the measurement precision and reliability of driving control are improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent introduces a traffic control apparatus as an intermediary that centralizes the computation of control information for collision avoidance. Instead of each vehicle independently processing sensor data with high-performance control units, the traffic control apparatus receives detection information from multiple vehicles and sensors, computes optimal control instructions, and transmits them back to vehicles. This mediator approach maintains high measurement precision while significantly reducing the computational burden and device complexity on individual vehicles.
Solution Approach 2:
The patent merges the computation functions of multiple vehicle control units into a single centralized traffic control apparatus. By combining the processing power and computational resources of the traffic control apparatus, the system achieves high-precision recognition and control computation without requiring each vehicle to be equipped with expensive high-performance control units. This merging approach resolves the contradiction between precision requirements and device complexity.
2Productivity
If latest control programs are deployed to each vehicle's control unit to improve collision avoidance performance, then the productivity and safety of driving control are improved, but the device complexity and update costs increase
Solution Approach 1:
The traffic control apparatus serves as an intermediary for program management and updates. Instead of distributing and managing control programs across multiple vehicle control units, the traffic control apparatus centralizes program storage, validation, and distribution. This allows latest control programs to be deployed efficiently to multiple vehicles simultaneously through the intermediary, improving productivity while simplifying program management complexity.
Solution Approach 2:
The traffic control apparatus performs multiple functions including sensor data reception, control information computation, program storage, program validation, and program distribution. This multi-functional intermediary approach allows latest control programs to be managed centrally and deployed to various vehicle types universally, improving productivity without increasing the complexity of individual vehicle control systems.
3Reliability
If advanced driving control systems with multiple sensors are installed on each vehicle to achieve reliable collision avoidance, then the reliability of safety control is improved, but the ease of manufacture and deployment across various vehicle specifications deteriorates
Solution Approach 1:
The traffic control apparatus acts as an intermediary that handles the complex computation and coordination required for reliable collision avoidance. Individual vehicles only need to transmit basic detection information and receive control instructions, significantly simplifying their system requirements. This intermediary approach maintains high reliability of collision avoidance while making the system easy to manufacture and deploy across various vehicle specifications.
Solution Approach 2:
The patent extracts the complex computation and coordination functions from individual vehicle control units and places them in the centralized traffic control apparatus. This extraction leaves vehicles with simpler, more standardized systems that are easier to manufacture and deploy across different vehicle types, while the reliability of collision avoidance is maintained through the sophisticated processing capabilities of the traffic control apparatus.
