Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the valve rod is directly connected to the movable ceramic piece, then the structure is simple, but the ceramic pieces are damaged due to external water pressure and collision force
Solution Approach 1:
The patent introduces a movable rod as an intermediary component between the valve rod and the movable ceramic piece. This movable rod absorbs external water pressure and collision forces, preventing direct transmission to the ceramic pieces. The movable rod includes a plug that can move to close the water inlet cavity, providing a buffer mechanism that protects the ceramic pieces from damage while maintaining operational simplicity.
2Device complexity
If the valve rod is directly connected to the movable ceramic piece, then the structure is simple, but the water outlet space is limited and water flow rate is restricted
Solution Approach 1:
The patent segments the valve structure into distinct functional components: a valve rod for operation, a movable rod with plug for water flow control, and separate movable and fixed ceramic pieces for sealing. This segmentation allows the movable rod and plug to create additional water outlet space by moving independently, thereby increasing water flow rate while keeping the overall structure relatively simple through modular design.
3Reliability
If a traditional valve shaft with ceramic pieces is used, then the valve can control water flow, but the valve shaft is complicated and costly with cumbersome installation
Solution Approach 1:
The patent extracts the ceramic pieces from a complex integrated valve shaft structure and positions them separately - a fixed ceramic piece on the water outlet end and a movable ceramic piece on the movable rod. This extraction simplifies the valve shaft to basic operational components (valve rod and movable rod) while maintaining water flow control functionality through the interaction between the movable plug and ceramic pieces.
4Ease of operation
If the valve rod rotates to drive the movable ceramic piece, then water can flow from different passages, but the impact between valve rod and ceramic pieces damages the ceramic pieces
Solution Approach 1:
The patent uses the movable rod with plug as an intermediary between the rotating valve rod and the movable ceramic piece. When the valve rod rotates to switch water passages, the movable rod moves axially to position the plug accordingly. This intermediary mechanism converts rotational motion to axial movement, preventing direct impact between the valve rod and ceramic pieces while maintaining the ability to direct water flow from different passages.
