Shower Head Waterway Switch and Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower heads with both waterway switch and water stop functions are bulky due to multiple operation buttons and separate mechanisms, leading to a complex and large structure.
Innovation Solution
A shower head design that integrates a switch device and water stop device within a housing, utilizing a single button with a link mechanism to independently control waterway switching and stopping, featuring a swing mechanism and valve spool system for compact operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation buttons and separate mechanisms are used for waterway switch and water stop functions, then the control functionality is complete, but the structure becomes complex and large in size
Solution Approach 1:
The patent combines the waterway switch function and water stop function into a single integrated control device. The switch mechanism and valve mechanism share common components including the button, link mechanism, and housing, allowing both functions to be controlled through one unified interface rather than separate mechanisms.
Solution Approach 2:
The single button serves multiple functions: pressing the front portion controls waterway switching while pressing the rear portion controls water stopping. The link mechanism and swing mechanism are designed to respond to different pressing positions of the same button, enabling one component to perform multiple control tasks.
2Adaptability or versatility
If multiple operation buttons are used for waterway switch and water stop functions, then the control functionality is complete, but the number of parts increases and operation becomes less convenient
Solution Approach 1:
The patent merges the control functions into a single button interface. The button is designed with distinct pressing regions (front portion for waterway switch, rear portion for water stop) that both activate different functions through the same physical component, simplifying the user interface.
Solution Approach 2:
The button is functionally segmented into different pressing zones. Pressing the front portion triggers the swing mechanism for waterway switching, while pressing the rear portion triggers the link mechanism for water stopping. This segmentation allows multiple functions to be accessed through a single unified component.
3Reliability
If separate switch mechanism and water stop device are used, then the functions work independently, but the structure occupies large space
Solution Approach 1:
The patent implements a nested structure where the valve mechanism is positioned within the housing that also contains the switch mechanism. The button and link mechanism are integrated into the same housing space, with components arranged concentrically and in overlapping configurations to minimize the overall volume.
Solution Approach 2:
The switch mechanism and valve mechanism share common structural elements including the housing, button, and link mechanism. By merging these mechanisms and eliminating redundant components, the patent achieves functional independence while reducing the overall size of the shower head.
