Automatic Return Shower Head with Handle-Mounted Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunctional shower heads are inconvenient to use as they cannot be operated by one hand due to long switching strokes, making them difficult to manage and switch functions efficiently.
Innovation Solution
An automatic return shower head design featuring a shower head body connected to a handle with a valve body, sealing ring, water distribution disc, and a switching return assembly that includes a knob, switching assembly, and return portion, allowing for one-handed operation by rotating the knob to adjust water flow and automatically returning to the initial position, facilitating quick and convenient switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional switching mechanism is used on the front surface of the shower head panel, then multiple functions can be provided, but the switching stroke becomes long and cannot be operated by one hand
Solution Approach 1:
The patent moves the switching mechanism from the front surface of the shower head panel to the handle, changing the spatial dimension and location of operation. This allows the user to operate the switching mechanism while holding the handle, enabling one-handed operation without compromising multifunctionality.
Solution Approach 2:
The patent introduces a valve body with water distribution holes as an intermediary component between the water supply passage and the shower head panel. This valve body, controlled by the switching mechanism on the handle, enables functional switching without requiring long stroke operation on the front surface.
2Adaptability or versatility
If the switching mechanism is located on the front surface of the shower head panel, then multiple functions can be achieved, but the switching speed becomes slow due to long switching stroke
Solution Approach 1:
By relocating the switching mechanism from the front surface to the handle, the patent shortens the switching stroke and enables faster operation. The proximity of the switching mechanism to the valve body allows for quicker response and faster water flow switching.
Solution Approach 2:
The valve body serves as an intermediary that responds quickly to the switching mechanism's movement. The water distribution holes in the valve body can be rapidly positioned to control water flow, achieving fast switching speed while maintaining multifunctionality.
3Adaptability or versatility
If a conventional switching mechanism with long stroke is used, then multiple functions can be provided, but the operation becomes inconvenient and requires two hands
Solution Approach 1:
The patent relocates the switching mechanism to the handle, changing the operational dimension from front surface manipulation to handle-based control. This allows the user to operate the mechanism while gripping the handle with one hand, simplifying the operation process.
Solution Approach 2:
The handle serves multiple functions: it is both the gripping component for holding the shower head and the operational component for controlling the switching mechanism. This multi-functionality reduces operation complexity while maintaining access to multiple shower functions.
