Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the valve body is provided with working chamber, forward washing chamber, backward washing chamber, and three filter element interfaces, then the filtration functions are achieved, but the internal structure becomes complex and production costs increase
Solution Approach 1:
The patent merges the forward washing chamber and backward washing chamber into a single inner chamber that can serve multiple functions through the rotation of the valve plate. The inner chamber alternates between serving as a working chamber, forward washing chamber, and backward washing chamber depending on the valve plate position, thereby reducing the number of separate chambers and simplifying the overall structure.
Solution Approach 2:
The inner chamber is designed as a multi-functional component that can perform multiple roles (working chamber, forward washing chamber, backward washing chamber) through the rotation mechanism. This universal design allows a single chamber to replace what would traditionally require three separate chambers, reducing structural complexity while maintaining all necessary filtration functions.
2Adaptability or versatility
If the fixed valve plate structure is made complex to achieve normal operation, backward washing and forward washing functions, then the filtration capabilities are improved, but production costs increase
Solution Approach 1:
The patent introduces a rotatable valve plate that can change its orientation and positioning dynamically to achieve different washing functions. Instead of using a complex fixed valve plate with multiple built-in features, the rotating valve plate simplifies the fixed structure by using motion to create functional diversity, making the fixed valve plate easier and cheaper to manufacture.
Solution Approach 2:
The valve system is segmented into a fixed valve plate and a rotatable valve plate, where the rotatable component handles the complexity of multiple functions through its movement, while the fixed valve plate maintains a simpler, more manufacturable structure. This segmentation allows the complex functionality to be achieved without making the fixed (and thus mass-produced) component overly complex.
3Adaptability or versatility
If three filter element interfaces are provided in the valve body, then the filtration, backward washing and forward washing functions are achieved, but the device complexity and material consumption increase
Solution Approach 1:
The patent combines multiple filter element interface functions into fewer physical interfaces by utilizing the rotation mechanism. The same filter element interface can serve different purposes (filtration, forward washing, backward washing) at different rotation positions, thereby reducing the total number of separate interfaces needed and reducing material consumption.
Solution Approach 2:
The filter element interfaces are designed to be multi-functional, where a single interface can handle multiple operations (filtration, washing in both directions) depending on the valve plate position. This universal design reduces the number of dedicated interfaces required, thereby reducing material consumption while maintaining full functionality.

AI summary
A multifunctional filter valve is provided. The multifunctional filter valve includes a valve body, a rotatable valve plate, a fixed valve plate, and a driving device. A water inlet, a water outlet, and a drainage outlet are disposed on a side wall of the valve body. The water outlet is configured to connect to a valve. An inner chamber and an outer chamber are defined in the valve body. The inner chamber defines a central drainage chamber, a working chamber, a backward washing chamber, and a blind chamber. A first filter element interface and a second filter element interface are defined at a bottom of the valve body. The combination of fixed valve plate and rotatable valve plate achieves a normal operation mode, a backward washing mode, and a forward washing mode. The multifunctional filter valve has a simpler structure and lower production cost.
