Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower heads require manual operation and removal to change water output patterns, necessitating two-handed operation and inconvenient user experience.
Innovation Solution
A shower head design featuring dual mechanical switches, one for controlling water output and another for pattern selection, allowing single-handed operation through a mechanism involving a rocker, sliding element, gear, and diverter system with recoil springs for efficient pattern switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation and removal of shower head is used to change water output pattern, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent combines the water output control function and water output pattern selection function into a single integrated shower head unit. The diverter mechanism is integrated within the shower head body, allowing both functions to be operated together without removal or separate manual manipulation of components.
Solution Approach 2:
The shower head incorporates automatic recoil springs that return the diverter and switching elements to their default positions after use. The mechanism automatically resets itself without requiring manual intervention to return components to initial states, enabling single-handed operation.
2Ease of operation
If single switch control is used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The control mechanism is segmented into two distinct switching elements: a first switch for controlling water output and a second switch for selecting water output patterns. This segmentation allows independent control of different functions, improving operational convenience while maintaining a compact integrated design.
Solution Approach 2:
The shower head is designed as a multi-functional unit that simultaneously provides water output control and water output pattern selection through its integrated dual-switch mechanism. Both functions are accessible through the same operational interface, eliminating the need for separate control systems.
3Productivity
If manual diverter manipulation is used, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The patent replaces the traditional manual diverter manipulation mechanism with an automated switching system. The diverter is actuated through a mechanical linkage connected to the second switch, which automatically directs water flow based on switch position without requiring manual handling of the diverter component itself.
Solution Approach 2:
The patent introduces intermediate mechanical components including a rocker arm, sliding element, and gear mechanism that mediate between the user's simple switch operation and the diverter's complex rotational movement. These intermediaries translate simple linear or rotational switch motion into the appropriate diverter positioning.
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
Enables single-handed control of water output and pattern changes, enhancing user convenience and reducing the need for manual diverter manipulation.
Implementation Method 1
a recoil spring provided to abut a side face of the diverting element and an inner face of the body to provide a recoil force to the diverting element after movement
Implementation Method 2
a gear rotatably mounted around the shaft and a rotor securely mounted on the shaft and having wolf teeth formed on a surface thereof to match with slanted teeth formed on a face of the gear such that when the rotor is rotated along with the shaft of the diverter in one direction, the gear is also rotated and when the rotor is rotated along with the shaft of the diverter is the other direction, only the rotor is rotated, but not the gear
Implementation Method 3
a driving rod having a first ratchet teeth formed on a side face thereof, a diverting element having a rod extending into a central through hole defined in the driving rod and a second ratchet teeth formed on a side face thereof to mate with the first ratchet teeth of the driving rod

AI summary
A shower head includes a body provided with a waterway. A first switch is movably mounted on the body to be responsible for selectively opening and closing the waterway and a second switch movably mounted on the body to be responsible for selectively changing water output patterns. The first switch has a rear pushbutton, a driving rod movably connected to the rear pushbutton and a diverting element movable relative to the body to be responsible for closing or opening the waterway. The second switch has a front pushbutton, a sliding element having a rack formed on a face thereof, a diverter rotatably received inside the body, a gear rotatably received inside the body and having first ratchet teeth and a rotor having second ratchet teeth selectively engaged with the first ratchet teeth to allow the rotation of the gear to drive the second ratchet teeth of the rotor to disengage with the first ratchet teeth of the gear as well as the rotor and the diverter to rotate accordingly.
