Self-Locking Shower Head Holder with Adjustable Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower head holders are either inconvenient to use due to requiring continuous force for adjustment or pose safety hazards as they can fall during operation, especially for individuals with disabilities.
Innovation Solution
An adjustable shower head holder with a self-locking structure that includes a holder body, lifting rod, locking assembly, and operating member, where the operating member changes the position of a support post within a sliding groove to adjust the friction between the tightening pad and lifting rod, allowing for easy height adjustment without continuous force and preventing the holder from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button is provided on the holder for unlocking and locking the locking member, then the shower head holder can be moved and positioned, but continuous press force is required which is inconvenient and cannot be used quickly and easily
Solution Approach 1:
The locking member is designed to automatically lock and unlock based on the position of the operating member. When the operating member rotates to different positions, the locking member self-activates to engage or disengage from the limiting groove, eliminating the need for continuous manual pressing force.
Solution Approach 2:
The adjustment mechanism operates in discrete periodic steps rather than continuously. The operating member has specific positioning grooves that correspond to different height positions, allowing the user to simply rotate to the desired position rather than maintaining continuous force throughout the adjustment range.
2Ease of operation
If a rotary knob is provided to change the tightness of the locking member, then the tightness can be adjusted, but both hands are required to rotate the knob and hold the holder, and the holder falls due to gravity
Solution Approach 1:
The system automatically maintains the holder at the selected height position through the self-locking mechanism. The locking member engages with the limiting groove to prevent gravitational falling, eliminating the need for continuous manual support and freeing both hands from the adjustment process.
Solution Approach 2:
The locking member is pre-designed to counteract the gravitational force before the holder can fall. By engaging the locking member with the limiting groove at predetermined positions, the system proactively prevents the harmful effect of gravity causing the holder to fall during or after adjustment.
3Adaptability or versatility
If the locking member is loosened by rotating the rotary knob, then the holder can be moved, but the holder falls due to gravity and must be supported by hand
Solution Approach 1:
The operating member with limiting grooves provides predetermined positioning points that guide the automatic locking mechanism. When the operating member rotates to a limiting groove position, the locking member self-locks to support the holder's weight, eliminating the need for manual support during movement.
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
The solution simplifies operation, ensures safety by maintaining friction to prevent the holder from sliding due to gravity, and allows for easy movement with minimal effort, making it convenient and safe for users, including those with disabilities.
Implementation Method 1
the friction between the tightening pad and the lifting rod can be changed, thereby achieving the purpose of positioning or moving the holder body. Through the first return spring, there is always friction between the tightening pad and the lifting rod, which can prevent the holder body from sliding downward due to the gravity
Implementation Method 2
prevent the holder body from sliding downward due to the gravity
Implementation Method 3
A first return spring is disposed between the tightening pad and a first end of the sliding seat

AI summary
An adjustable shower head holder with a self-locking structure includes a holder body, a lifting rod, a locking assembly, and an operating member. The holder body is movably connected to the lifting rod through the locking component. The operating member is movably fitted to the locking assembly for switching a locked state and an unlocked state of the locking assembly. With a single operation of the operating member, the locked state and the unlocked state of the locking assembly can be changed, thereby positioning or moving the holder body. The operation is simpler. The use is safer.
