Solution Overview
Problem
Ceramic valves in bathroom equipment, such as shower faucets, suffer from noise and wear due to complex movements and require improved stability in water output.
Innovation Solution
A ceramic balancing check valve with a valve housing, controller, balancing valve unit, and checking valve unit that allows for the automatic balancing of hot and cold water pressures, preventing reverse flow, and enabling stable water output through a rotating ceramic plate mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex movements are used in ceramic valves to achieve water mixing and direction switching, then the valve can perform multiple functions, but noise and wear increase
Solution Approach 1:
The patent merges the mixing valve and check valve functions into a single integrated ceramic valve body. The ceramic plate serves multiple purposes: it acts as both the mixing element and the check valve disc, eliminating the need for separate moving components. This consolidation reduces the number of moving parts, thereby reducing noise and wear while maintaining water mixing and direction switching capabilities.
Solution Approach 2:
The ceramic plate is designed to perform multiple functions simultaneously: it controls water flow direction, mixes hot and cold water, and prevents reverse flow through its check valve function. This multi-functionality is achieved through the integrated design where the same ceramic component handles all these tasks, reducing overall system complexity and harmful effects.
2Adaptability or versatility
If multiple components are used in ceramic valves to achieve water mixing and direction control, then the valve can handle complicated water flow requirements, but the operation becomes complex
Solution Approach 1:
The patent combines multiple valve functions into a single integrated structure. The ceramic plate integrates the mixing valve function and check valve function, eliminating the need for separate components. This simplification reduces operational complexity while maintaining the ability to handle various water flow requirements through a single control mechanism.
3Speed
If conventional valve designs are used to allow water flow control, then the valve can respond quickly to user input, but water output stability deteriorates
Solution Approach 1:
The patent introduces a balancing valve as an intermediary component that automatically adjusts water flow to maintain stable output. The balancing valve works in conjunction with the check valve to ensure that water pressure and flow rate remain consistent, preventing fluctuations while maintaining quick response to user input through the ceramic plate control mechanism.
