Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual user selection via HMI screen is used to choose a berth, then the system is simple to operate, but the automation level is low and user intervention is required
Solution Approach 1:
The system performs preliminary actions by pre-collecting port information through sensors at different timings and storing it in the control unit. This preparation allows the system to quickly determine open berths without real-time manual intervention, thereby improving automation while managing complexity through advance data gathering.
Solution Approach 2:
The boat's control unit autonomously processes sensor data to identify open berths without requiring external assistance or manual HMI operations. The system serves itself by automatically comparing port information across different timings and making berth selection decisions independently, enhancing automation while keeping the interface simple.
2Measurement precision
If real-time sensor data only is used to determine open berth, then the response is fast, but the accuracy is reduced due to lack of historical context
Solution Approach 1:
The system collects and stores port information at different timings in advance, creating a historical database before the actual berth determination is needed. This preliminary data collection enables accurate comparison between current and past port states, improving measurement precision while the stored data eliminates the need for extended real-time observation.
Solution Approach 2:
The control unit uses feedback from previously collected port information to enhance current berth determination accuracy. By comparing real-time sensor data with historical data from different timings, the system refines its open berth identification, achieving high precision without proportionally increasing data collection time.
3Productivity
If user selects berth manually through HMI, then the interface is simple, but the productivity is low due to required user intervention
Solution Approach 1:
The autonomous system performs berth determination independently without requiring user interaction with HMI interfaces. The control unit automatically processes sensor data, identifies open berths, and provides recommendations, thereby significantly improving productivity while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The system replaces manual mechanical HMI operations with automated electronic sensor-based detection and processing. Instead of users manually selecting berths through interface interactions, the control unit electronically processes port information and autonomously determines suitable berths, enhancing productivity while simplifying the operational process.
Data Source
AI summary
A system, adapted for a boat to accumulate and utilize information of a port, the system including a control unit having a processor configured to function as a determining part that determines an open berth of the port; and a display part that displays the open berth determined by the determining part on a display. The control unit determines the open berth based on a first data and a second data, the first data includes information of the port obtained at a first timing by a sensor disposed on the boat, the second data includes information of the port obtained at a second timing, wherein the first timing is different from the second timing, and the first timing is a present time.
