Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rotary shower heads have limited rotation range, are difficult to control, and are not suitable for varying water pressures, leading to poor shower comfort and increased water usage.
Innovation Solution
A rotary spray shower head design featuring a main body, water distributing plate, impeller, pinion, driven gear, and water outlet head assembly, which uses a planet deceleration mechanism to control rotating speed and achieve effective rotary spray discharge, with a simple structure that accommodates different water pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the rotation range of each discharge nozzle is increased to improve shower coverage, then the rotary water area is enlarged, but the number of nozzles must increase which increases components, processing complexity and assembly difficulty
Solution Approach 1:
The patent combines multiple nozzle functions into a single integrated rotary discharge structure. Instead of having separate nozzles for each discharge function, the invention uses one rotary discharge opening that can rotate to cover multiple areas, merging the functions of multiple nozzles into a single component while achieving broader coverage.
Solution Approach 2:
The rotary discharge opening serves multiple functions: it can discharge water to different locations, provide both shower water and massage water functions, and adapt to different water pressures. This single component replaces what would traditionally require multiple specialized nozzles, reducing complexity while maintaining versatility.
2Ease of operation
If an impeller directly turns a rotor for outlets to turn and discharge water, then rotary discharge is achieved, but the rotational speed cannot be controlled and water pressure requirements are not flexible
Solution Approach 1:
The patent introduces a dynamic control mechanism where the rotary discharge opening can be adjusted and controlled. The discharge opening is connected to a control mechanism that allows adjustment of the rotary motion, enabling control over the discharge pattern and adaptation to different water pressures while maintaining ease of operation.
