Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring the quality of lubricants in ship engines, particularly the dissolved iron content, are complex, require trained personnel, and are not conducive to automation, making them difficult to implement on board ships where engines are sophisticated and prone to wear or corrosion.
Innovation Solution
An installation comprising a lubricant circulation pipe connected to a buffer tank with valves for controlled lubricant flow and a sensor for determining dissolved iron content, allowing for autonomous and simplified monitoring of lubricant quality without the need for complex manipulation or elaborate equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sophisticated equipment and trained personnel are used to monitor lubricant quality, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical and laboratory-based monitoring equipment with an optical sensor system that uses light transmission through the lubricant. The sensor measures dissolved iron content and other quality parameters optically, eliminating the need for sophisticated mechanical analysis equipment and trained personnel while maintaining measurement precision.
Solution Approach 2:
The monitoring system is designed to operate autonomously without requiring trained personnel intervention. The sensor continuously monitors lubricant quality in real-time, and the system can alert operators to potential issues automatically, making the equipment self-sufficient and easy to operate while maintaining high measurement accuracy.
2Measurement precision
If laboratory equipment is used to detect dissolved iron content, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex laboratory analytical equipment with a simple optical sensor that measures dissolved iron content through light transmission properties of the lubricant. This substitution maintains detection accuracy while dramatically simplifying operation to the point where no specialized training is required.
Solution Approach 2:
The system uses simple, inexpensive optical sensors that can be easily replaced if needed, rather than requiring expensive, complex laboratory equipment. This approach maintains sufficient measurement precision while making the system much easier to operate and maintain.
3Ease of operation
If automated monitoring system is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent achieves automation by replacing complex mechanical sampling and analysis systems with a simple optical sensing system. The sensor continuously measures lubricant quality parameters without mechanical intervention, and the data can be automatically processed and alerted, achieving automation with minimal added complexity.
Solution Approach 2:
The optical sensor system is designed to measure multiple lubricant quality parameters simultaneously (dissolved iron content, basicity index, and other properties) using a single device, rather than requiring multiple separate systems. This multi-functionality achieves comprehensive automated monitoring without proportionally increasing system complexity.

AI summary
The invention relates to a facility (2) for monitoring the variation in the quality of a lubricant circulating in a device (M) which comprises at least one pipe (4) for circulating (F1) the lubricant, said pipe being connected, upstream, to the device (M) and, downstream, to an oil pan. The facility furthermore includes a first valve (20) for controlled interruption of the circulation (F1) of the lubricant in the pipe (4), a buffer tank (26) for accumulating lubricant, a first bypass line (28) connected to the pipe (4) upstream from the first valve (20), as well as to the buffer tank (26). The facility likewise comprises a second valve (32) for controlled interruption of the circulation of the lubricant in the first bypass line (28), a second line (42) for discharging lubricant, from the buffer tank (26) to the oil pan, and a third valve (44) for controlled interruption of the circulation of the lubricant in the second discharge line (42). A sensor (50) makes it possible to determine the dissolved iron content of an amount of lubricant contained in the buffer tank (26).
