Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual filter cleaning is used, then the filter element can be cleaned of impurities, but the process requires long downtimes and labor-intensive work
Solution Approach 1:
The filter device performs self-cleaning through an automated backflushing mechanism. The adjusting body automatically reverses the flow direction to flush impurities from the filter element without requiring manual intervention, transforming the filter device into a self-maintaining system that eliminates labor-intensive cleaning operations and minimizes downtime.
Solution Approach 2:
The system implements periodic backflushing cycles where the adjusting body automatically switches between filtration mode and backflushing mode. This periodic reversal of flow direction cleans the filter element at regular intervals, maintaining continuous operation while preventing impurity accumulation that would otherwise require lengthy manual cleaning.
2Object-affected harmful factors
If recycled materials are processed, then environmental friendliness is improved, but the filter device requires frequent cleaning due to higher contamination
Solution Approach 1:
The automated backflushing mechanism enables the filter device to self-maintain during recycled material processing. By automatically reversing flow to flush impurities, the system handles the higher contamination levels inherent in recycled materials without requiring manual intervention, thus maintaining productivity while enabling environmentally friendly recycling operations.
Solution Approach 2:
The periodic backflushing mechanism ensures continuous processing of recycled materials by automatically cleaning the filter element during operation. This eliminates interruptions and maintains continuous productive action, allowing the system to handle contaminated recycled materials efficiently without sacrificing productivity for environmental benefits.
3Ease of operation
If the filter housing is opened for cleaning, then the filter element is accessible, but the filter housing must be closed again increasing complexity
Solution Approach 1:
The adjusting body with its automated backflushing capability eliminates the need to open the filter housing for cleaning. The system performs self-maintenance through internal flow reversal, removing the complex sequence of opening, cleaning, and closing the housing, and simplifying the overall device operation while maintaining filter element accessibility through automated means.

Implementation Method 1
a first flow path for the plasticized molding material is defined by channels in the filter body and in the adjusting body, wherein the first flow path is formed such that the plasticized molding material is filtered
Implementation Method 2
in the second position of the adjusting body relative to the filter body a second flow path for the plasticized molding material is defined by channels in the filter body and in the adjusting body, wherein the second flow path is formed such that the channels and/or a filter element are at least partially flushed and/or backflushed
