Top Showerhead Height Adjustment With Damping Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower systems with fixed-type top showerheads lack customization for user height adjustment, making installation and usage inconvenient.
Innovation Solution
A height adjustment structure comprising a movable rod, a fixed rod, and a damping mechanism, where the damping mechanism adjusts the friction force between the rods to allow easy unlocking and locking, enabling simple height adjustment of the top showerhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastener runs through the fixed rod to lock the movable rod, then the movable rod can be locked securely, but the adjustment operation becomes inconvenient as the fastener must be removed to move the rod
Solution Approach 1:
The patent replaces the traditional mechanical fastener system with a magnetic field-based locking system. The movable rod contains a magnet that interacts with a ferromagnetic material in the fixed rod to provide locking force, eliminating the need for removable fasteners and enabling easier adjustment while maintaining secure locking.
Solution Approach 2:
The patent introduces a damping mechanism that uses fluid resistance (pneumatic/hydraulic principle) to control the movement of the movable rod. The damping hole in the plug creates fluid resistance that dampens movement, providing controlled adjustment while the magnetic field maintains locking.
2Ease of operation
If the movable rod is freely movable for easy adjustment, then the height can be customized, but the rod cannot be securely locked at the desired position
Solution Approach 1:
The patent uses a magnetic field-based locking system where a magnet in the movable rod interacts with ferromagnetic material in the fixed rod. This provides secure locking at the desired position while maintaining ease of adjustment, as the magnetic force automatically engages when the rod is positioned.
Solution Approach 2:
The patent changes the physical state parameters by introducing a damping mechanism with a damping hole and plug. This controls the fluid resistance to dampen the movement of the movable rod, allowing the rod to be moved easily for adjustment while securing it firmly at the desired position through controlled damping.
3Ease of manufacture
If the top showerhead is fixed at a predetermined height, then the installation is simple, but the height cannot be customized to match different user heights or room heights
Solution Approach 1:
The patent divides the rod system into a fixed rod and a movable rod that can slide relative to each other. The movable rod can be adjusted to different heights and locked in place using the magnetic field and damping mechanism, enabling height customization while maintaining simple installation through the modular segmented structure.
Solution Approach 2:
The patent transforms the fixed rod structure into a dynamic system where the movable rod can slide along the fixed rod for height adjustment. The magnetic field provides automatic locking at the desired position, and the damping mechanism controls the movement, enabling both simple installation and height customization.
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
Facilitates easy and convenient height adjustment of the top showerhead by allowing direct movement of the movable rod after unlocking, simplifying the adjustment process and ensuring secure locking.
Implementation Method 1
A friction force between the movable rod and the fixed rod is changed by the damping mechanism under an action of an external force, so as to locking or unlocking the movable rod and the fixed rod
Implementation Method 2
one end of the operating member corresponding to the movable rod is connected to a preload spring
