Shower Head Water-Saving Switching Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower heads with switchable spray modes require high force to operate due to large friction resistance, leading to laborious button pressing and complex structures, and often necessitate separate controls for water flow and spray mode, increasing cost and complexity.
Innovation Solution
A shower head water-saving switching structure featuring a ratchet wheel, push rod, and dual-functional button that rotates a water distribution gear to control communication between water chambers, reducing friction and simplifying operation by adjusting the overlapping area of a flow limit protruding block and side water inlet to manage water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the communication area between the water distribution opening of the switching disk and the water inlet of the functional water chamber is small, then water flow is reduced for water saving, but the friction resistance increases making button operation laborious
Solution Approach 1:
The patent introduces a flow control assembly with adjustable flow control holes that can dynamically change the water flow area. The flow control assembly includes a flow control body with multiple flow control holes of different sizes, allowing the system to adjust water flow dynamically rather than using a fixed small communication area. This resolves the contradiction by enabling water flow reduction without permanently constraining the water distribution opening, thus maintaining ease of operation while achieving water saving when needed.
2Productivity
If a flow control assembly is added to control effluent water flow, then water flow can be controlled, but the structure becomes more complicated
Solution Approach 1:
The patent combines the flow control function with the existing switching disk structure. The flow control assembly is integrated into the water distribution chamber, and the flow control body is positioned within the same chamber where the switching disk operates. The button mechanism serves dual purposes: both switching between different water distribution openings and controlling water flow through the flow control holes. This merging of functions reduces overall structural complexity while maintaining water flow control capability.
Solution Approach 2:
The button mechanism is designed to perform multiple functions: it can press the switching disk to change water distribution modes and simultaneously press the flow control assembly to adjust water flow. This multi-functionality eliminates the need for separate controls, reducing structural complexity while achieving both spray mode switching and water flow control through a single operational element.
3Adaptability or versatility
If separate controls are used for water flow and spray mode, then each function can be controlled independently, but the cost increases
Solution Approach 1:
The patent designs the button mechanism to serve dual functions: pressing the switching disk for spray mode selection and pressing the flow control assembly for water flow adjustment. This allows independent control of both functions through a single operational element, maintaining adaptability while reducing the number of separate control mechanisms needed. The flow control assembly includes multiple flow control holes that can be selectively activated, providing versatile flow control options.
