Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressing-controlled valve cores face issues with flow loss and manufacturing complexity when attempting to control water of two different temperatures or qualities, leading to higher production costs and defective rates due to the need for a thicker ceramic valve block and more complex flow passages.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional pressing-controlled valve core uses a vertical hole configuration to control water flow, then the flow control function is achieved, but flow loss occurs
Solution Approach 1:
The patent inverts the conventional vertical hole configuration by implementing a through-flow control type design where water flows horizontally through the ceramic valve block rather than vertically. This reversal of the flow path eliminates dead zones and improves flow efficiency while maintaining effective flow control through the pressing-controlled linkage device.
Solution Approach 2:
The patent transitions from a single-dimensional vertical flow path to a multi-dimensional through-flow path that passes through the ceramic valve block. This dimensional change allows water to flow through the entire structure, eliminating stagnant areas and reducing flow loss while preserving control functionality.
2Quantity of substance
If the ceramic valve block is made thicker to accommodate two water inlets, then the mixed water flow capacity is improved, but manufacturing difficulty and production cost increase
Solution Approach 1:
The patent segments the flow paths into distinct channels within the ceramic valve block, allowing two separate water inlets to be accommodated without requiring excessive thickness. The segmented design organizes the flow paths efficiently, reducing the overall block thickness needed while maintaining adequate mixed water flow capacity.
Solution Approach 2:
The patent utilizes through-flow passages that extend through the ceramic valve block in multiple dimensions, allowing efficient accommodation of two water inlets and outlet without requiring increased block thickness. This multi-dimensional flow path arrangement optimizes space utilization and reduces manufacturing complexity.
3Adaptability or versatility
If the flow passages are made more complex to control two water sources, then the mixing function is improved, but the defective rate of finished products increases
Solution Approach 1:
The patent employs segmented and clearly defined flow passages within the ceramic valve block that separate hot and cold water paths until the mixing point. This segmentation approach simplifies the overall passage design by providing clear boundaries and reducing the complexity of interconnections, thereby lowering the defective rate while maintaining effective mixing capability.
Solution Approach 2:
The patent inverts the conventional approach by using through-flow passages that pass completely through the ceramic valve block rather than creating complex internal routing. This inversion simplifies the passage design, reduces potential leak points, and lowers the defective rate while preserving the mixing function through proper flow path arrangement.
4Adaptability or versatility
If the pressing-controlled linkage device is applied for single water source control, then the flow adjustment function is achieved, but it cannot control two different temperatures or qualities
Solution Approach 1:
The patent enhances the pressing-controlled linkage device to perform multiple functions: it can control both single water source flow adjustment and dual water source mixing. The linkage device is designed with a rotational inner shell and driving claws that can operate in different modes, allowing one device structure to replace what would traditionally require separate control mechanisms for single and dual water source applications.
Solution Approach 2:
The patent implements a dynamic linkage device with a rotational inner shell that can adapt its configuration based on operating mode. The driving claws can engage with different components to enable either single water source control or dual water source mixing, providing versatility without requiring multiple fixed-configuration devices. This dynamic adaptability increases water source control capability while avoiding the complexity of separate dedicated systems.

AI summary
Disclosed is a pressing-controlled mixing valve core with through flow control type on the top, having a shell body, a rotational inner shell, a water guide base, fixed and moving ceramic chips, a flow adjustment top seat and a pressing-controlled lifting actuator. By changing the rotation angle of the moving ceramic chip, its mixed water adjustment hole has different communication states to the guide holes of the fixed ceramic chip, so as to adjust the mixture state of the inlet water flow. Through a pressing action by the user, the water control rod head on the lifting shaft of the actuator will have rising and descending positions inside the vertical through hole and through flow passage of the flow adjustment top seat, so as to change the sectional area of the water flow in the through flow passage and adjust the output water flow of the pressing-controlled mixing valve core.
