Vessel Propulsion Diagnosis via On-Board Network Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel propulsion systems face challenges in diagnosing failures, particularly when multiple propulsion apparatuses are synchronized, as individual diagnosis methods struggle to identify issues such as bearing binding or oil solidification, leading to wasted labor and time in identifying malfunctioning components.
Innovation Solution
A vessel propulsion system with an on-board network that allows a diagnosis device to connect to all propulsion apparatuses, transmitting operating state information on a common time axis, enabling comparison and identification of abnormalities across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual diagnosis is performed by connecting service tools to each propulsion apparatus, then diagnosis can be conducted for each unit, but it becomes difficult to identify failures in synchronized propulsion apparatuses and wastes time and labor
Solution Approach 1:
The patent merges the diagnosis functions for multiple propulsion apparatuses into a single integrated system. The service tool connects to the vessel's network to simultaneously access and compare operating state information from all propulsion apparatuses, eliminating the need for individual connections and enabling efficient identification of failures in synchronized systems.
Solution Approach 2:
The service tool is designed with multi-functionality to diagnose multiple propulsion apparatuses simultaneously through a single connection point. By accessing the network, the service tool can retrieve and analyze operating state information from any or all propulsion apparatuses, making it a universal diagnostic solution rather than requiring separate tools for each unit.
2Loss of information
If service tools are connected to multiple propulsion apparatuses individually to log operating state information, then data can be collected, but comparison becomes difficult due to different time axes
Solution Approach 1:
The service tool provides a universal interface for collecting operating state information from all propulsion apparatuses through a single network connection. It automatically handles the complexity of data synchronization and time-axis alignment, presenting unified comparative data without requiring manual coordination between multiple separate tool connections.
