Elastic Tooth Shower Bracket Assembly for Quiet Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower plug brackets with angle adjustment functions using hard mechanical teeth suffer from loud noise and short service life due to collisions during rotation.
Innovation Solution
A shower plug bracket with a locking structure comprising a first component and a second component, where the first component's teeth engage with the second component's teeth to form an elastic gear position, allowing for quiet rotation and resetting, and featuring a friction pad system for lifting and lowering functionality, reducing noise and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hard mechanical teeth are used for gear engagement, then the structure is simple and easy to manufacture, but loud noise is generated during rotation and service life is shortened
Solution Approach 1:
The patent changes the material parameter of the gear teeth from hard mechanical material to elastic material (such as rubber). This parameter change allows the teeth to deform elastically during engagement, absorbing collision energy and reducing noise while maintaining the simplicity of the gear structure
Solution Approach 2:
The patent uses composite material structure where elastic material (rubber) is combined with the gear body. This composite approach provides both the structural integrity needed for gear function and the elastic properties needed for noise reduction, resolving the contradiction between simple structure and noise control
2Device complexity
If hard mechanical teeth are used for gear engagement, then the structure is simple, but service life is reduced due to collision without cushioning
Solution Approach 1:
The patent applies beforehand cushioning by using elastic material for the gear teeth that can deform and absorb collision energy before damage occurs. This elastic cushioning effect protects the teeth from impact damage during rotation, extending service life while keeping the gear structure simple
Solution Approach 2:
Changing the material parameter from hard to elastic provides inherent cushioning capability. The elastic deformation of the teeth during engagement absorbs shock and reduces stress concentration, preventing premature failure and extending the reliable service life of the gear mechanism
3Object-generated harmful factors
If elastic material is used for gear teeth, then noise is reduced and service life is extended, but manufacturing complexity increases
Solution Approach 1:
The patent uses elastic material (such as rubber) for the gear teeth, which can be manufactured as flexible components. This approach reduces noise through elastic deformation while the manufacturing process involves molding or forming operations that are relatively straightforward for elastic materials, balancing noise reduction with manufacturability
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 provides a quiet operation and extended service life by using an elastic gear position for tooth engagement and a friction pad system for lifting and lowering, ensuring smooth angle adjustments without noise interference and maintaining functionality.
Implementation Method 1
an elastic member cooperates with and is disposed between the first component and the plug bracket portion. When the plug bracket portion rotates upward or downward, the first component is driven to move in a direction toward the friction pad to enable the friction pad to be reset to a state in which the friction pad abuts the rod
Implementation Method 2
the base is disposed with a friction pad configured to abut the rod to limit movement of the base

AI summary
A shower plug bracket and a moving assembly are provided. The shower plug bracket includes a base and a plug bracket portion. The plug bracket portion is configured to rotate up and down to adjust a use angle, the two cooperate with a locking structure, the locking structure includes a first component and a second component, the first component is connected to the base, the second component is disposed on the plug bracket portion, the first component is disposed with first teeth, the second component is disposed with second teeth, and the first teeth are engaged with the second teeth. When the plug bracket portion rotates upward or downward, the first teeth of the first component are disengaged from the second teeth of the second component. When the plug bracket portion stops rotating, the first teeth and the second teeth reset to an engaged state.
