Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If V2X communication uses multiple frequency bands to provide various services, then service diversity and functionality are improved, but system complexity and difficulty of managing communication reliability worsen
Solution Approach 1:
The patent segments the communication system into distinct functional modules: a receiving unit that captures signals from multiple frequency bands, a determining unit that identifies service types, and a processing unit that handles different services according to predetermined rules. This modular segmentation allows the system to manage multiple frequency bands and services without overwhelming complexity, as each module performs a specific function independently.
Solution Approach 2:
The patent implements preliminary action by establishing predetermined processing rules and configurations before communication occurs. The system pre-configures how different service types should be processed, prioritized, and managed across multiple frequency bands. This advance preparation enables the system to handle complex multi-band communications without real-time decision-making complexity, as the processing logic is already determined.
2Adaptability or versatility
If V2X communication transmits safety services across multiple frequency bands, then service coverage and functionality are improved, but transmission reliability and delivery assurance worsen
Solution Approach 1:
The patent applies preliminary action by pre-establishing processing rules for safety services before transmission occurs. The system determines in advance how safety-critical messages should be prioritized, routed, and processed across different frequency bands. This preliminary configuration ensures that safety services maintain high reliability regardless of the complexity of multi-band transmission, as the critical processing logic is predetermined and consistently applied.
Solution Approach 2:
The patent implements local quality by applying different processing strategies to different service types within the same communication system. Safety services receive specialized handling with higher priority and predetermined processing rules, while other services may use standard processing. This differentiated approach ensures that safety-critical transmissions maintain high reliability even when operating across multiple frequency bands with varying conditions.
3Productivity
If V2X communication device processes rich media data and EAS messages efficiently, then information delivery speed is improved, but processing complexity and computational load worsen
Solution Approach 1:
The patent segments the message processing function into distinct components: an obtaining unit that extracts EAS information and rich media data from received messages, and a notification unit that delivers this information to the user. This segmentation allows the system to process different types of information (EAS alerts and rich media) through specialized pathways, improving delivery speed without requiring the entire system to handle all processing complexity simultaneously.
Solution Approach 2:
The patent applies the extraction principle by separating critical EAS information and rich media data from the overall message structure. The obtaining unit specifically extracts these key elements and delivers them through dedicated notification pathways, rather than processing the entire message uniformly. This extraction approach accelerates the delivery of time-critical information while reducing the computational burden on the overall system, as only essential elements require rapid processing.
