Hair Brush Ejection Mechanism for Rapid Head Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair brushes with handles can be cumbersome and require manual handling, leading to increased styling time and risk of skin burns when removing the brush head, especially when using multiple brush heads or a hair dryer simultaneously.
Innovation Solution
A hair brush system with a rapid ejection mechanism that allows the brush head to be forcibly separated from the handle using depressions on the handle, eliminating the need for manual handling and preventing skin burns by allowing the brush head to be ejected without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hair brush with handle is used, then the brush can be easily positioned and manipulated, but the brush head cannot be quickly removed and requires manual handling which increases styling time and risk of skin burns
Solution Approach 1:
The ejection finger is designed as a resilient (flexible) component that can dynamically change its state from engaged to ejected. When the button is pressed, the ejection finger flexes and propels the brush head away from the handle. This dynamic mechanism enables rapid brush head removal without manual handling, resolving the contradiction between ease of operation and time loss.
2Ease of operation
If a conventional hair brush with handle is used, then the brush can be easily positioned and manipulated, but manual handling of the brush head increases risk of skin burns
Solution Approach 1:
The ejection mechanism extracts the brush head from the handle by propelling it away using the resilient ejection finger. This extraction process is automated through the button-activated mechanism, eliminating the need for manual handling of the brush head and thereby preventing skin burns while maintaining ease of operation.
3Adaptability or versatility
If multiple brush heads are used with a single handle, then versatility is improved, but the complexity of switching between brush heads increases
Solution Approach 1:
The ejection mechanism enables self-service operation for brush head switching. The resilient ejection finger automatically propels the brush head away when the button is pressed, eliminating the need for manual manipulation. This self-acting mechanism simplifies the switching process between multiple brush heads, maintaining versatility while reducing operational complexity.

AI summary
A hair brush system with a rapid, consistent, and efficient means for connecting and ejecting the brush handle from the brush head. The hair brushes feature a strong support member structure that gives the hairbrush strength while the handle and brush head are connected. The handle has a pair of barbed ejection fingers that engage and retain the brush head. When separation of the brush handle and the brush head is desired, the user depresses an actuator associated with each ejection finger. The compressed ejection finger has a tip that comes into contact with a conical protrusion in the brush head. The resulting action first disengages the brush head and then causes an outward force to be applied to the brush head thereby ejecting it from the handle.
