Fluid Maintenance Control for Powered-Down Machine Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fluid maintenance in large-capacity diesel engines and other machinery fail to efficiently sequence and time fluid operations, leading to excessive downtime and wear due to inconvenient fluid access locations and inadequate data collection and analysis, resulting in premature component exhaustion.
Innovation Solution
Implementing a system with flexible conduits, quick disconnect couplings, and control valves to facilitate efficient fluid evacuation and refill processes, along with data collection and analysis to optimize maintenance schedules and reduce downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fluid evacuation and refill operations are performed using conventional methods with fixed outlet ports at the bottom of machines, then gravity flow can be utilized for fluid removal, but the outlet ports are inconveniently located and the processes are time-consuming and difficult to perform
Solution Approach 1:
The fluid maintenance system is segmented into multiple mobile outlets positioned at different locations around the machine, allowing selection of the most convenient access point rather than using a single fixed bottom outlet. This enables operators to perform fluid evacuation and refill operations from multiple accessible positions.
Solution Approach 2:
The outlet ports are made mobile rather than fixed, allowing them to be repositioned to convenient locations around the machine. This dynamic positioning system eliminates the constraint of having outlets only at the bottom, enabling flexible access from various positions depending on operational needs.
2Productivity
If multiple evacuations and refills of fluid receptacles are performed manually without sequencing, then fluid maintenance can be completed, but the processes are not timed or sequenced to maximize performance and excessive downtime occurs
Solution Approach 1:
The control system sequences and times the multiple evacuations and refills in advance, preparing the system for optimal performance. By pre-coordinating the timing and sequence of fluid operations across multiple receptacles, the system maximizes maintenance efficiency and minimizes total downtime.
Solution Approach 2:
The control system monitors and coordinates the timing of multiple fluid operations, using feedback from sensors and system status to optimize the sequencing of evacuations and refills. This ensures that operations are performed in the most efficient sequence to minimize downtime.
3Loss of information
If data collection and analysis systems are not implemented during fluid operations, then simple manual procedures can be used, but crucial data for scheduling maintenance and monitoring performance issues is not collected or analyzed
Solution Approach 1:
Sensors and monitoring devices collect data during fluid operations and feed this information back to the control system, which analyzes the data to optimize maintenance scheduling and detect performance issues. This continuous feedback loop ensures crucial operational data is captured and utilized.
Solution Approach 2:
Manual data collection and analysis procedures are replaced with automated electronic sensors and control systems that continuously monitor fluid operations. This substitution of mechanical/manual processes with electronic systems enables comprehensive data collection without proportionally increasing operational complexity.
4Reliability
If component maintenance is delayed due to inconvenient fluid access locations, then simpler systems can be used, but components are exhausted long before the expected end of their useful lives
Solution Approach 1:
The fluid maintenance system is divided into multiple segments or outlets positioned at different locations around the machine, allowing convenient access to each fluid receptacle without requiring complex disassembly or difficult-to-reach positions. This segmented approach enables regular maintenance intervals to be maintained.
Solution Approach 2:
The mobile outlet system dynamically positions access points at convenient locations, eliminating the need to delay maintenance due to inaccessible fluid receptacles. Operators can perform maintenance at regularly scheduled intervals because outlets are positioned for easy access rather than being fixed in inconvenient locations.
Data Source
AI summary
A system. The system includes a power source, a control module of a machine, and a fluid component. The fluid component is configured to establish an electrical connection between the power source and the control module during performance of a fluid operation on the machine when the machine is powered down.
