Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structure of existing oral irrigator handles for desktop models is complex, leading to higher costs and difficulties in installation and manufacturing, and the control mechanism for water flow is inconvenient.
Innovation Solution
A waterway control device with a valve body, control member, reset member, and push button that allows for simplified movement between blocking and opening positions, using a sliding fit and sealing mechanisms to control liquid flow through the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional switch structure is used to control waterway opening and closing on the oral irrigator handle, then the water flow control function is achieved, but the device structure becomes complex and manufacturing cost increases
Solution Approach 1:
The control member integrates multiple functions: it acts as both the sealing element (replacing traditional valve components) and the control lever (replacing separate actuating mechanisms). By merging the valve seat, seal, and actuator into a single integrated control member that rotates within the accommodating cavity, the patent eliminates the need for separate switch components while maintaining reliable water flow control.
Solution Approach 2:
The control member serves multiple purposes simultaneously: it provides sealing against the water inlet when in the first position, acts as a lever arm for the introducing member to rotate, and controls the opening/closing of the waterway. This multi-functional design replaces what would traditionally require multiple separate components, simplifying the overall device structure.
2Reliability
If a conventional switch structure is used to control waterway opening and closing, then the water flow control function is achieved, but installation and manufacturing difficulty increases
Solution Approach 1:
The control member integrates multiple functions: it acts as both the sealing element (replacing traditional valve components) and the control lever (replacing separate actuating mechanisms). By merging the valve seat, seal, and actuator into a single integrated control member that rotates within the accommodating cavity, the patent eliminates the need for separate switch components while maintaining reliable water flow control.
Solution Approach 2:
The reset member is designed to automatically return the control member to the first position (closed state) when the introducing member is not actuated. This self-resetting mechanism eliminates the need for additional return springs or complex reset mechanisms, simplifying both manufacturing and installation while ensuring the waterway defaults to a closed safe state.
3Device complexity
If control buttons are arranged on the desktop oral irrigator body, then the device structure is simplified, but user convenience deteriorates due to difficult control operation
Solution Approach 1:
The control mechanism transitions from a linear push-button arrangement on the desktop body to a rotational dimension within the handle. The control member rotates between a first position (waterway closed) and a second position (waterway open) within the accommodating cavity, providing intuitive tactile feedback and easy operation while maintaining a compact handle structure.
Solution Approach 2:
The introducing member acts as an intermediary between the user's finger input on the push button and the control member's rotational movement. It translates the linear pushing motion into rotational motion of the control member, enabling convenient control operation while keeping the push button accessible on the handle exterior.
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
Simplifies the structure of the oral irrigator handle, reducing manufacturing complexity and improving user convenience by enabling easy control of water flow without increasing costs.
Implementation Method 1
One end of the reset member abuts against the control member, the other end of the reset member abuts against a wall of the accommodating cavity
Implementation Method 2
The control member is capable of blocking the accommodating cavity when the control member is at the first position
Implementation Method 3
The control member is capable of opening the accommodating cavity when the control member is at the second position
Implementation Method 4
The introducing member is in sliding fit with the control member, the introducing member is configured to cause the control member to move from a first position to a second position when the push button moves relative to the valve body

AI summary
A waterway control device is provided, which includes a valve body, a control member, a reset member and a push button. The valve body is provided with an accommodating cavity. The control member is arranged in the accommodating cavity. One end of the reset member abuts against the control member, and the other end of the reset member abuts against a wall of the accommodating cavity. The push button is movably arranged on the valve body, and provided with an introducing member. The introducing member is in sliding fit with the control member, and configured to cause the control member to move from a first position to a second position. The reset member enables the control member to restore and remain at the first position. The control member is capable of blocking the accommodating cavity at the first position, and opening the accommodating cavity at the second position.
