Ship Engine RPM Control Server for Adaptive Speed Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to dynamically control the revolutions per minute (RPM) of a ship's engine due to its weight and buoyancy properties, making it difficult to introduce innovative control systems that can change engine speed efficiently.
Innovation Solution
A control server is installed on the ship to select a different RPM based on detected inputs, receive condition information, and determine suitability before transmitting a control command, compatible with the existing control system.

Engineering Contradiction Analysis
1Productivity
If a new control system is introduced to dynamically change engine speed, then operational efficiency is improved, but device complexity and installation costs increase
Solution Approach 1:
The control server is designed to perform multiple functions: it monitors engine RPM, receives driver inputs, determines suitability of RPM changes, and transmits control commands. By consolidating these functions into a single multi-functional device, the system improves operational efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The control server acts as an intermediary between the driver's input and the engine's control system. It receives the desired RPM input, evaluates suitability based on current operating conditions, and only then transmits the control command to the engine. This intermediary approach enables intelligent RPM management while maintaining compatibility with existing control systems.
2Adaptability or versatility
If RPM control functionality is added to the existing control system, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: an input unit for receiving driver commands, a determination unit for evaluating suitability, and a transmission unit for sending control commands. This segmentation allows the new RPM control functionality to be added as a separate module rather than integrating it throughout the entire control system, thereby improving adaptability while minimizing increases in overall complexity.
Solution Approach 2:
The control server performs preliminary assessment of whether an RPM change is suitable before actually executing the control command. By pre-evaluating operating conditions and determining suitability in advance, the system adds adaptive RPM control functionality without requiring complex real-time decision-making throughout the entire control system.
