Integrated Fast Switch for Direct Shower Water Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of sanitary devices like showers struggle to control water flow without seeing the switch due to its separate wall-mounted location, risking scalding and inconvenience.
Innovation Solution
A fast switch is integrated between the water outlet apparatus and pipe, allowing direct control via the water outlet apparatus, featuring a tube body with a valve body and pressing piece to block or connect water ends, enabling fluidic switching without needing to see the switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the switch is arranged separately on the wall, then the water outlet apparatus and control are separated for safety, but the user cannot easily locate and operate the switch without seeing it
Solution Approach 1:
The patent merges the switch function directly into the water outlet apparatus by integrating a pressing piece on the outlet end that can directly actuate the valve body. This eliminates the need for a separate wall-mounted switch, allowing users to control water flow by simply pressing the outlet apparatus itself, which is always visible and within reach.
Solution Approach 2:
The pressing piece serves as an intermediary element that transfers the user's pressing action from the water outlet apparatus directly to the valve body. This mechanical intermediary enables direct control without requiring the user to locate or interact with a separate control mechanism.
2Reliability
If the switch is arranged separately on the wall, then the control is independent from the water outlet, but the user risks accidental scalding when searching for the switch in the dark
Solution Approach 1:
By combining the control function with the water outlet apparatus itself, the patent ensures that only intentional direct contact with the outlet will activate or deactivate water flow. This eliminates the risk of accidental scalding from misreaching for a separate switch in the dark, while maintaining full control capability.
3Ease of operation
If the water inlet end and water outlet end can approach or move away from one another, then direct control is enabled, but the tube body structure becomes more complex
Solution Approach 1:
The patent incorporates movable components within the tube body, specifically allowing the water inlet end and water outlet end to approach or move away from one another. This dynamic structure enables the pressing piece to transmit force to the valve body when the outlet is pressed, providing direct control while managing structural complexity through purposeful mobility.
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 quick and safe water control without searching for a wall-mounted switch, preventing accidental scalding and ensuring easy operation even with closed eyes.
Implementation Method 1
the pressing piece of the tube body can press the switch element of the valve body by the mutual approach of the water inlet end and the water outlet end

AI summary
A fast switch for a sanitary device, which fast switch is designed to connect a water source and a water outlet apparatus, the fast switch includes a tube body with a water inlet end for connecting to the water source, a water outlet end to connect to the water outlet apparatus, with both being able to approach or move away from each other, and a pressing piece disposed on the water outlet end that moves therewith; and a valve body in the tube body which realizes at least two fluidic switching states between the water inlet and outlet ends. The valve body includes a switch element, and the pressing piece is able to press the switch element due to the mutual approaching of the water inlet and outlet ends, whereby the valve body is switched to selectively set one of the two fluidic switching states between the water inlet and outlet ends.
