Valve Core Seat With Manual Bypass After Switch Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction taps with solenoid valve switches face issues where damage to the switch results in constant water flow or inability to control water outlet, necessitating replacement and increased costs.
Innovation Solution
A valve core module with a water path switching mechanism that allows a tap to function as an ordinary tap after the electric control switch is damaged, featuring a compact design with integrated water inlet and outlet passages, and a movable plate for water mixing and distribution, enabling manual operation when the electric control fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a solenoid valve switch is used for induction water outlet control, then automatic water outlet control is achieved, but the system reliability deteriorates when the switch is damaged
Solution Approach 1:
The water outlet control system is segmented into two independent paths: an automatic control path (first water outlet passage controlled by solenoid valve) and a manual control path (second water outlet passage). This segmentation allows the manual path to function independently when the automatic control fails, resolving the reliability issue while maintaining automation capability.
Solution Approach 2:
The valve core structure is designed to change its position parameter between different states: normally positioned to block the second water outlet passage, and rotatable to open it. This parameter change enables switching between automatic and manual control modes, allowing the system to maintain functionality when the solenoid valve fails.
2Ease of operation
If a multi-functional valve core is used to adjust water temperature and control water path, then the device complexity increases, but the ease of operation improves
Solution Approach 1:
The valve core is designed as a multi-functional component that simultaneously performs water temperature adjustment (by rotating to mix hot and cold water) and water path control (by blocking or opening different passages). This multi-functionality consolidates multiple operations into a single component, improving ease of operation while the modular design keeps complexity manageable.
Solution Approach 2:
The invention merges the water temperature control function and water path distribution function into a single integrated valve core structure. The valve core combines a rotor for temperature adjustment and a plunger for path control, merging multiple functions that would traditionally require separate components, thus improving operational efficiency.
3Device complexity
If the first and second water outlets are controlled only by a ceramic rotor, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The system introduces dynamic adaptability through the rotatable valve core with plunger mechanism, which can dynamically switch between different water path configurations. While the ceramic rotor provides static positioning, the added plunger mechanism enables dynamic adaptation to different operational needs (normal mode, emergency mode, temperature adjustment), significantly improving versatility without excessive complexity.
