Ship Hybrid System Mode Synchronization for Error-Resistant Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ship hybrid systems with a single button operation for mode switching face challenges in controlling multiple hybrid systems and grasping their operation statuses, leading to potential erroneous operations, especially on ships that sway easily.
Innovation Solution
A ship with multiple hybrid systems is equipped with a control device that sets all hybrid systems to the same operation mode, improving control and reducing the risk of erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single button operation is used for mode switching, then ease of operation is improved, but reliability deteriorates due to increased possibility of erroneous operation
Solution Approach 1:
The control device performs preliminary actions by automatically setting all hybrid systems to the same operation mode before manual switching can occur. This preliminary synchronization prevents erroneous operations by ensuring systems are in a known consistent state before the occupant interacts with the switching mechanism.
Solution Approach 2:
The display device provides visual feedback showing the operation status of each hybrid system. This feedback mechanism allows the occupant to verify the current state before and after mode switching, reducing erroneous operations by making the system state transparent and confirming that switching occurred as intended.
2Adaptability or versatility
If multiple hybrid systems are controlled independently, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control device merges the control functions for multiple hybrid systems into a unified control mechanism. By automatically setting all hybrid systems to the same operation mode simultaneously, the system reduces the complexity of managing multiple independent control systems while maintaining the ability to adapt to different operational requirements through the display and switching interface.
