Electric Toothbrush Head Connector for Stable Vibration Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric toothbrushes experience unstable vibrations due to the easy deviation and dislocation of the elastic member connecting the brush handle and head, leading to separation issues.
Innovation Solution
A connector system with a connector body and an elastic member is used to securely attach the brush head to the handle, featuring a protruding portion for fixation and a clamping mechanism to prevent separation, ensuring stable vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elastic member is used to couple the drive shaft to the brush head, then the brush head can be detachably mounted on the handle, but the elastic member is easily deviated and dislocated causing unstable vibrations
Solution Approach 1:
The connector is divided into a connector body and a separate elastic member, allowing the elastic member to be freely deviated and dislocated while the connector body maintains stable connection through its protruding portion and limiting groove structure
Solution Approach 2:
The connector body acts as an intermediary between the elastic member and the brush head, providing a stable connection interface with the protruding portion and limiting groove that prevents direct coupling issues between the elastic member and the brush head
2Ease of operation
If the elastic member is freely deviated and dislocated, then the brush head can be easily attached and detached, but the vibrations become unstable
Solution Approach 1:
The connector is segmented into a connector body and elastic member, allowing the elastic member to be freely deviated and dislocated for easy attachment and detachment, while the connector body maintains stable connection through its protruding portion and limiting groove structure
Solution Approach 2:
The connector body provides localized stable connection through its protruding portion and limiting groove structure, while the elastic member provides localized flexibility for attachment and detachment, creating different local qualities in different parts of the connector system
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 connector system enhances the stability of the brush head attachment, maintaining consistent vibration and improving user experience by preventing separation and enhancing manufacturing simplicity.
Implementation Method 1
a connector (20) fixedly arranged inside the brush head body (10), the connector (20) comprising a connector body (30) and an elastic member (40) mounted on the connector body (30), the elastic member (40) having a first fixing end engaged with a first limiting portion (38) along a first engagement direction (A) parallel to an insertion direction (X), a second fixing end engaged with a second limiting portion (39) along a second engagement direction (B) same as the first engagement direction (A), an abutting portion (433) facing towards and configured to abut against the drive shaft (250), and a clamping relationship between the abutting portion (433) and the drive shaft (250)
