Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid cell systems for oil filtration in internal combustion engines face issues with oil leakage during mounting and demounting, and they occupy excessive installation space, necessitating a solution that prevents leakage while optimizing space usage.
Innovation Solution
A fluid cell with a valve device that controls oil supply and discharge through adjustable valve bodies, and a volume-variable oil reservoir design, which adapts to the oil volume after discharge, combined with a docking station that ensures fluid connections and seals lines during removal, using preloading elements and adjustable tubular bodies to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluid cell is designed with fixed oil lines and sealed connections to prevent oil leakage, then reliability is improved, but device complexity increases due to additional sealing mechanisms
Solution Approach 1:
The patent applies dynamics by making the oil lines flexible rather than rigid, allowing them to adapt their shape and position during mounting and demounting operations. This dynamic flexibility enables the lines to maintain fluid-tight connections without requiring complex active sealing mechanisms, as the flexible lines can naturally conform to connection interfaces while preventing oil leakage.
Solution Approach 2:
The patent changes the physical state or configuration parameters of the oil lines by making them collapsible and flexible. This parameter change allows the lines to transition between different states (expanded when in use, collapsed when not needed), enabling reliable sealing through the inherent properties of the flexible material rather than through complex mechanical sealing components.
2Quantity of substance
If the oil reservoir is designed with fixed volume to ensure sufficient oil storage, then quantity of substance is improved, but volume of moving object increases occupying excessive installation space
Solution Approach 1:
The patent applies dynamics by designing the oil reservoir with variable volume capability. The reservoir can expand when oil needs to be stored and collapse when oil is discharged or not needed. This dynamic volume adjustment allows the system to maintain sufficient oil storage capacity when required while minimizing the occupied installation space during operation or when the cell is demounted from the docking station.
Solution Approach 2:
The patent changes the volume parameter of the oil reservoir by making it collapsible. This allows the reservoir volume to adapt based on the amount of oil stored and the operational state of the fluid cell. When the fluid cell is mounted and oil is discharged to the engine, the reservoir collapses to reduce overall volume, thereby optimizing installation space while maintaining the ability to store sufficient oil when needed.
3Reliability
If valve devices are added to control oil lines for leakage prevention, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by designing the system so that the flexible, collapsible oil lines themselves provide the sealing function through their inherent material properties and configuration. The lines automatically seal when collapsed or properly positioned, eliminating the need for separate active valve devices or complex sealing mechanisms. The system uses the natural behavior of the flexible lines to ensure fluid-tight connections during mounting and demounting operations.

AI summary
A fluid cell for an assembly and for filtering oil includes a fluid cell housing with a housing opening and partly surrounds a housing interior, a housing cover attached releasably to the fluid cell housing for closing the housing opening, and a filter device arranged in the housing interior for filtering the oil, in which a filter element is arranged and which fluidically communicates with a raw oil line for conducting the oil to be filtered into the filter device and with a clean oil line for conducting the filtered oil out of the filter device. An oil reservoir is arranged in the housing interior for storing oil, which fluidically communicates with an oil reservoir line for conducting oil out of the oil reservoir, and a fluid cell valve device for closing and opening the raw oil line, the clean oil line, and the oil reservoir line.
