Water Outlet Spray Switching With Axial Sliding Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary water outlet devices require active user operation to switch between water spray patterns, leading to potential forgetfulness and inappropriate water spray usage, which can cause splashing.
Innovation Solution
A water outlet device with a rotatable water-passing member and outlet member, featuring jet holes and water flow channels, a sliding block, and an elastic element, allowing automatic switching between water spray types based on rotation and water pressure, with the elastic element returning to its initial state to reset the position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user manually operates the water outlet device to switch between water spray patterns, then the device can provide multiple water spray types, but the user may forget the previous setting and cause water splashing
Solution Approach 1:
The device automatically remembers and restores the previous water spray pattern setting when turned on, eliminating the need for users to manually remember or re-select their preferred setting. The system serves itself by maintaining state information and automatically reconfiguring the water outlet member to the previous position without user intervention.
Solution Approach 2:
The device provides feedback to the user about the current and previous water spray settings through visual indicators or other signaling mechanisms, allowing users to understand what setting is currently active and what was previously selected, thereby reducing confusion and memory burden.
2Adaptability or versatility
If the water outlet device uses a rotating mechanism to switch between water flow channels, then multiple spray patterns can be achieved, but the structure becomes more complex
Solution Approach 1:
The water outlet member is merged with the rotating mechanism, combining the water flow distribution function with the position switching function into a single integrated component. This reduces the number of separate parts and simplifies the overall structure while maintaining the ability to switch between multiple water flow channels.
Solution Approach 2:
The rotating water outlet member serves multiple functions: it distributes water to different spray patterns, remembers previous positions, and provides user interface interaction. This multi-functionality reduces the need for separate components and simplifies the device architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables automatic and reliable switching between water spray types without user intervention, preventing splashing by aligning water flow channels accurately and maintaining device position through resilience force.
Implementation Method 1
The elastic element supports the sliding block in the axial direction. The elastic element is in a state of accumulating resilience force. When the water supply is turned off, the elastic element releases the resilience force and returns to its initial state.

AI summary
A water outlet device includes a water-passing member having jet holes, a water outlet member having different water flow channels, a sliding block, and an elastic element that supports the sliding block in the axial direction. The water-passing member has a first limiting portion, and the water outlet member has a first supporting portion. The sliding block includes a second supporting portion and a second limiting portion. The first limiting portion is connected to the second limiting portion, such that the sliding block is only movable along the axial direction of the water outlet member. The second supporting portion presses against or separates from the first supporting portion, and the sliding block and the water outlet member can rotate relative to each other through the second supporting portion and the first supporting portion, such that the jet holes are in communication with the different water flow channels.
