Solution Overview

Problem

Existing filter devices for internal combustion engines lack a compact and versatile design for efficiently discharging purified fluid, with limitations in fluid flow distribution and potential for increased flow resistance.

Innovation Solution

A filter device with a plate-shaped filter element featuring a central outflow pipe and a housing-associated clean fluid outflow opening, allowing for selective and adjustable discharge of purified fluid, reducing flow resistance and enabling separate fluid flow paths for different applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single outflow pipe is used for discharging purified fluid, then the device structure is simple, but the fluid flow distribution is limited and flow resistance increases

Engineering Contradiction:
Improvedevice structureVSAvoidfluid flow distribution
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The single outflow pipe is segmented into multiple outflow pipes (first outflow pipe and second outflow pipe), allowing the purified fluid to be discharged through multiple separate paths. This segmentation enables better fluid flow distribution and reduces flow resistance while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If a single outflow pipe is used, then the device is compact, but the versatility for different fluid discharge applications is limited

Engineering Contradiction:
Improvedevice sizeVSAvoidfluid discharge applications
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The filter device is designed with multiple outflow pipes that can serve different functions simultaneously. The first outflow pipe can discharge purified fluid to one location while the second outflow pipe discharges to another location, enabling the compact device to handle multiple fluid discharge applications and increase versatility without increasing device size.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Volume of moving object

If the outflow pipe passes through the filter element, then the device is compact, but the flow resistance increases due to the narrow passage

Engineering Contradiction:
Improvedevice compactnessVSAvoidflow resistance
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The fluid flow path is segmented into multiple channels through the provision of multiple outflow pipes. This allows the total flow to be distributed across several passages, reducing the flow resistance in each individual passage while maintaining the compact overall device dimensions.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If a single discharge path is used, then the device structure is simple, but the ability to supply fluid to different locations is limited

Engineering Contradiction:
Improvedischarge path structureVSAvoidfluid supply to different locations
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The filter device incorporates multiple outflow pipes that can be directed to different locations, enabling the device to supply purified fluid to multiple destinations simultaneously. This multi-functional design allows a single filter device to serve various applications without requiring complex additional discharge path structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A filter device has a filter housing and a plate-shaped filter element that is arranged in the filter housing. The filter element has oppositely positioned lateral surfaces that form an inflow side for a fluid to be filtered and an outflow side for the clean fluid. A first clean fluid outflow opening is introduced into the filter housing for discharging the clean fluid. An outflow pipe passes through the filter element for discharging the clean fluid through a second clean fluid outflow opening provided at the outflow pipe. The first clean fluid outflow opening is arranged at a spacing relative to the outflow pipe.
