Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pump is used to create partial vacuum for forcing liquid passage through the filtration device, then the filtration function is achieved, but the cost increases substantially due to pump purchase and installation expenses
Solution Approach 1:
The patent removes the pump from the system entirely, extracting the problematic component that caused high costs and complexity. Instead of using a pump to create partial vacuum, the invention uses a reservoir positioned at a higher elevation than the filtration tank, utilizing gravity to naturally force liquid passage through the filtration device.
Solution Approach 2:
The patent replaces the mechanical pump system with a passive gravitational system. The elevation difference between the reservoir and filtration tank creates the necessary pressure differential without mechanical intervention, eliminating the need for powered equipment and associated installation complexity.
2Reliability
If a pump is inserted into the hydraulic system to force liquid passage, then the filtration function is achieved, but the installation complexity increases due to technical measures required to reproduce optimum operating conditions and prevent cavitation

3Reliability
If known filtration machines are designed with complex structures to achieve filtration function, then the filtration capability is ensured, but the flexibility for configuration variations after installation is reduced
Solution Approach 1:
The patent divides the filtration system into separate, modular components: a filtration tank, a rotary drum filter with filtration mesh, a cleaning device, and a reservoir. These segmented components can be independently configured and positioned, allowing flexibility in installation arrangements while maintaining effective filtration function.
Solution Approach 2:
The patent introduces a rotary drum filter that can rotate to different positions, allowing dynamic adjustment of the filtration mesh orientation. The drum can rotate to present different surfaces for filtration, cleaning, and contaminant discharge, providing configuration flexibility without requiring complex fixed structures.
4Reliability
If known filtration machines are designed with complex structures to ensure filtration function, then the filtration capability is maintained, but the maintenance operations become complicated and costly
Solution Approach 1:
The patent divides the filtration system into separate, modular components: a filtration tank, a rotary drum filter with filtration mesh, a cleaning device, and a reservoir. These segmented components can be independently configured and positioned, allowing flexibility in installation arrangements while maintaining effective filtration function.
Solution Approach 2:
The patent incorporates a cleaning device that automatically cleans the filtration mesh on the rotary drum filter. The cleaning mechanism uses fluid jets to remove contaminants from the mesh surface, reducing the need for manual maintenance and intervention while maintaining filtration capability.

Function Achieved in This Case
The solution reduces costs by eliminating pump expenses, simplifies maintenance, and allows for flexible configuration and easy adaptation to system requirements, while maintaining effective filtration and self-cleaning capabilities.
Implementation Method 1
The flow of fluid that is established between the two tanks can occur by way of natural phenomena, for example by gravity, or by way of external means, which force the liquid to pass in the filtration device. This passage often occurs thanks to the use of a pump which draws the filtered liquid from the filtered liquid collection tank, thus creating a negative difference between the two tanks
Implementation Method 2
a filtration device which is interposed between a tank for collecting the contaminated liquid and a tank for collecting the filtered liquid
