Faucet Flow Control Rod for Outlet Switching and Flow Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet systems lack the ability to simultaneously switch between water outlet passages and control the flow of water, making operations like rinsing or washing inconvenient, especially with upward water spray structures.
Innovation Solution
A flow control device featuring a movable rod that reciprocates to switch between outlet passages and rotates to control the flow, equipped with a flow control part and control knob that adjusts the water flow by sealing and unsealing outlet passages, allowing users to select discharge positions and flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-passage switching function is provided in faucets, then users can switch between different outlet passages, but the device cannot control the outlet flow of a specific water outlet simultaneously
Solution Approach 1:
The patent combines the passage switching function and flow control function into a single integrated operation. The movable rod simultaneously performs both functions: its reciprocating motion switches between outlet passages while its rotating motion controls the flow rate of the selected passage. This merging eliminates the need for separate operations and resolves the contradiction between versatility and ease of operation.
Solution Approach 2:
The movable rod is designed as a universal control element that performs multiple functions: it switches passages through reciprocating motion and controls flow rates through rotating motion. This multi-functionality allows a single component to handle both passage selection and flow regulation, improving operational convenience while maintaining adaptability.
2Adaptability or versatility
If an upward water spray structure is used, then the faucet can provide upward water discharge, but users cannot control the upward outlet flow for tasks like rinsing mouths and washing faces
Solution Approach 1:
The patent integrates flow control capability into the upward water discharge function. The movable rod's rotation directly controls the flow rate of the upward outlet, allowing users to adjust the water flow for rinsing mouths and washing faces without requiring additional controls. This resolves the contradiction by combining passage selection and flow control in a single operational mechanism.
3Ease of operation
If separate faucet switches are added to control flow, then flow control is possible, but the operation becomes inconvenient and complex
Solution Approach 1:
The patent merges the flow control function into the existing passage switching mechanism. The movable rod serves as a universal control that performs both passage switching and flow regulation, eliminating the need for separate faucet switches. This reduces operational complexity while maintaining full flow control capability.
Solution Approach 2:
The movable rod is designed as a multi-functional control element that handles both passage selection and flow rate adjustment. This universal approach allows users to control both functions through a single component, reducing the number of operations required and simplifying the overall device complexity.

AI summary
The invention relates to the field of bath products, and provides a flow control device. The flow control device comprises a movable rod capable of reciprocating to switch water into different outlet passages, wherein a flow control part circumferentially extends and protrudes out of the movable rod, and the movable rod rotates to drive the flow control part to rotate to control the flow in the corresponding outlet passage. During use, the movable rod is pressed to control the switching the outlet passages, and users can select the position where water is discharged as required, for example, water is discharged upwards or downwards. Moreover, the movable rod rotates to drive the flow control part to rotate to flexibly control the flow of a certain outlet, such as the upward outlet flow, to facilitate daily washing of the users.
