Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucets rely on ordinary valve cores that regulate water flow based on pressure and handle position, leading to inefficiencies and inconvenience due to potential water wastage and blockages in flow restrictors.
Innovation Solution
A flow regulating switch valve with a control key, switch assembly, diaphragm assembly, rotating ring, sliding block, and magnet, where the rotating ring's inclined plane drives the sliding block and magnet to control the diaphragm assembly, allowing precise regulation of the water outlet size and flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ordinary valve cores with flow restrictors are used, then water flow can be restricted, but the flow restrictor may be easily blocked and is inconvenient to use
Solution Approach 1:
The patent replaces the traditional mechanical flow restrictor with a magnetic control system. A magnet is positioned to interact with a diaphragm, using magnetic force to regulate water flow instead of mechanical restriction. This eliminates the blockage issue associated with mechanical flow restrictors while maintaining flow control capability.
Solution Approach 2:
The patent changes the control parameter from mechanical position (handle opening angle) to magnetic field strength. By adjusting the position or strength of the magnet, the water flow is regulated through magnetic force variations rather than mechanical opening changes, improving reliability and control precision.
2Quantity of substance
If ordinary valve cores with handle opening angle control are used, then water flow can be regulated, but improper opening position may result in wasting of water
Solution Approach 1:
The patent replaces the mechanical handle opening angle control with magnetic field-based control. The magnet's position or strength can be precisely adjusted to achieve exact flow control, eliminating water wastage from improper handle positioning. The magnetic system provides more precise and responsive flow regulation.
Solution Approach 2:
The diaphragm in the magnetic control system provides inherent feedback - as water flow changes, the diaphragm position adjusts accordingly, which in turn modifies the magnetic field interaction. This creates a self-regulating system that prevents water wastage by automatically optimizing flow based on actual delivery conditions.
3Device complexity
If a single control mechanism is used for both opening/closing and flow regulation, then device complexity is reduced, but the mechanism must perform multiple functions
Solution Approach 1:
The patent implements a magnet that serves dual functions: it controls valve opening/closing and simultaneously regulates water flow. By positioning the magnet to interact with the diaphragm, a single component performs both on/off control and flow modulation, reducing device complexity while maintaining full functionality.
Solution Approach 2:
The patent merges the opening/closing control and flow regulation functions into a single magnetic control mechanism. Instead of separate controls for valve operation and flow adjustment, the magnet's position or strength simultaneously manages both functions, simplifying the overall control system.
