Solution Overview
Problem
Current methods for monitoring and controlling vessel speed are inadequate, particularly in environments with limited visibility and reliance on vessel-provided information, failing to accurately measure speed and enforce speed limits effectively.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera-based visual information is used to measure vessel speed, then speed measurement is possible, but measurement precision deteriorates in obscured environments with cloud and mist
Solution Approach 1:
The patent combines acoustic information from sound signal receiving apparatus with visual information from camera-based systems to measure vessel speed. By merging these two independent measurement approaches, the system maintains measurement capability in obscured environments where visual information alone would be insufficient, thereby resolving the contradiction between measurement precision and reliability in poor visibility conditions.
2Ease of operation
If AIS radio wave collection is used to measure vessel speed, then speed data can be obtained, but the system cannot operate independently of vessel-provided information
Solution Approach 1:
The patent introduces acoustic information as an intermediary measurement source that does not depend on vessel-provided AIS data. By using sound signals emitted by the vessel's engine as a mediator for speed measurement, the system achieves ease of operation while maintaining independence from vessel information systems, resolving the contradiction between operational ease and reliability.
3Reliability
If sound signal receiving apparatus is used to identify vessel vibration information, then speed measurement is possible in obscured environments, but device complexity increases
Solution Approach 1:
The patent designs the sound signal receiving apparatus to perform multiple functions: identifying vessel type through acoustic characteristics, measuring vessel speed, and providing collision warnings. By making the device multi-functional, the system achieves reliable speed measurement in obscured environments without proportionally increasing complexity, as the same hardware infrastructure serves multiple purposes.
