Solution Overview
Problem
Existing electromagnetic distributors in smart bathroom equipment have long response times and cannot independently control multiple water channels, limiting their ability to meet diverse user needs.
Innovation Solution
The electromagnetic distributor features a housing with multiple solenoid valve cores and magnetic conducting chambers, allowing for independent control of each water outlet through a magnetic field, enabling rapid switching and multiple water outlet modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a stepper motor is used to control the rotor to rotate and switch water channels, then the water channel switching can be realized, but the response time becomes long and cannot meet rapid switching needs
Solution Approach 1:
The patent replaces the stepper motor-driven mechanical rotation system with an electromagnetic valve system. Each water channel is controlled by an independent electromagnetic valve that opens or closes instantaneously through electromagnetic actuation, eliminating the mechanical inertia and rotation time of the stepper motor system. This substitution of mechanical rotation with electromagnetic actuation achieves rapid response and shortens switching time.
2Adaptability or versatility
If a single rotor-stator structure is used for water channel control, then the structure is simple, but only one water channel can be opened at a time and multiple outlet modes cannot be achieved
Solution Approach 1:
The patent divides the water channel control system into multiple independent electromagnetic valves, with each valve controlling a specific water channel. This segmentation allows each channel to be controlled independently, enabling multiple channels to be opened simultaneously or in any combination, thus achieving diverse water outlet modes. The segmentation of control functions into separate valves provides versatility while maintaining manageable structural complexity.
