Push-button switching structure for hand-held shower head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held shower heads require both hands to switch between different spray modes, making the operation laborious and inconvenient.
Innovation Solution
A push-button switching structure for hand-held shower heads that uses a combination of a water route upper cover, pre-compressed spring, water-dividing disc, driver, separation spring, worm, positioning pin, water route lower cover, and push button to control multiple spray modes with a single push button, allowing for convenient switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotation panel is used to switch spray modes, then multiple spray modes can be achieved, but both hands are required for operation making it laborious and inconvenient
Solution Approach 1:
The switching mechanism is segmented into distinct functional components: a push button for user input, a worm gear for motion conversion, a driver with bevel teeth for transmission, and a water-dividing disc with multiple water outlets for spray mode selection. This segmentation allows the complex switching function to be achieved through simple, modular components that can be operated with one hand.
Solution Approach 2:
The traditional rotation panel mechanism is replaced with a push-button actuation system combined with worm gear and bevel gear transmission. This mechanical substitution transforms the continuous rotational motion requirement into discrete push-button presses, significantly improving ease of operation while maintaining multiple spray mode functionality.
2Ease of operation
If a push button mechanism is implemented to control spray modes, then operation becomes more convenient, but the switching space and component arrangement become constrained
Solution Approach 1:
The switching mechanism components are nested within the existing shower head body structure. The worm gear is positioned within the switching space, the driver is mounted on the water-dividing disc, and the push button extends through the housing. This nesting arrangement accommodates the additional components without significantly increasing the overall footprint of the shower head.
Solution Approach 2:
The push button extends in the axial direction through the housing, utilizing the depth dimension of the switching space rather than requiring additional radial or lateral area. This dimensional approach allows the actuation mechanism to be compact while maintaining accessibility for user operation.
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
The solution enables simple and compact operation with one push button to control multiple spray modes, enhancing user convenience and stability.
Implementation Method 1
a pre-compressed spring, disposed between an inner wall of the switching space close to the water inlet and an end face of the water-dividing disc
Implementation Method 2
a separation spring, disposed between the driver and the worm
Implementation Method 3
a worm, another end of the worm is a stopping part extending out of the switching hole of the switching space
Implementation Method 4
The center of the water-dividing disc is formed with first bevel teeth. The edge of the water-dividing disc is formed with a ratchet. An end face of the driver is formed with second bevel teeth to mate with the first bevel teeth
Implementation Method 5
The edge of the water-dividing disc is formed with a ratchet. Another end of the positioning pin is a pawl to mate with the ratchet
