Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a larger-size softening valve is manufactured to increase water inlet and outlet amounts, then the water flow requirement is met, but the production and manufacturing costs increase and installation and transportation become less convenient
Solution Approach 1:
The valve body is divided into multiple functional cavities (first cavity, second cavity, third cavity, fourth cavity) with dedicated flow paths for different operations. Each cavity handles specific water flow requirements, allowing the valve to achieve high water flow capacity without increasing overall valve size, thus resolving the contradiction between productivity and ease of manufacture
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of cavities and flow paths within the valve body. By optimizing the vertical and radial distribution of water channels and cavities, the design maximizes water flow capacity within a compact valve structure, avoiding the need for larger valve dimensions while maintaining high productivity
2Adaptability or versatility
If various cavities and flow guiding holes are provided in the valve body and valve plate to implement multiple functions, then the multifunctional requirements are met, but the structure becomes complex which limits water inlet and outlet amounts
Solution Approach 1:
The valve body is designed as a multifunctional integrated structure where the same valve body and valve plate assembly serve multiple purposes: water production, backwashing, regeneration, and salt tank water replenishment. The coordinated movement of the valve plate and piston enables different cavities to be connected to different ports based on operational mode, achieving versatility without proportionally increasing structural complexity
Solution Approach 2:
The valve plate is positioned within the valve body such that the valve plate's cavities and channels are nested within the valve body's larger cavity structure. This nested arrangement allows multiple flow paths to coexist in a compact configuration, reducing overall structural complexity while maintaining multifunctionality
3Adaptability or versatility
If various cavities and flow guiding holes are provided in the valve body and valve plate to implement multiple functions, then the multifunctional requirements are met, but the water inlet amount and outlet amount are limited
Solution Approach 1:
The valve body is segmented into multiple independent cavities (first, second, third, fourth cavities) with dedicated flow paths. During water production, multiple cavities can simultaneously handle water flow, effectively increasing the total water inlet and outlet amounts while maintaining multifunctional capabilities for backwashing, regeneration, and salt tank replenishment

AI summary
The disclosure provides a multifunctional softening valve. The valve includes a valve body, a movable valve plate, a fixed valve plate and a driving device. Wherein the valve body defines a water inlet, a water outlet, a drainage port, a water passing port, and a regenerant inlet. The valve body includes an inner chamber and an outer chamber. The inner chamber includes a central drainage cavity, a working cavity, a backwashing cavity, a regeneration cavity, a blind cavity, a forward washing cavity and a water injection cavity, and a water blocking structure is disposed at the backwashing cavity or the water outlet. The fixed valve plate and the movable valve plate cooperate to achieve the functions of water producing, backwashing, regeneration, forward washing and water injection, so that the structure of the softening valve is more excellent, and the performance is more excellent.
