Hair Brush With Movable Frames For Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hairbrushes accumulate hair fibers between their bristles, leading to unsanitary conditions, reduced efficacy, and an unsightly appearance, with existing cleaning methods requiring significant manual effort and often resulting in premature disposal of the brush.
Innovation Solution
A hairbrush design featuring cantilevers that allow the frames to bend and separate, creating gaps for easy access to remove accumulated hair without additional instruments, enabling quick and convenient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hairbrush design with fixed bristles is used, then the brush provides stable structure and effective hair brushing, but hair accumulates between bristles making cleaning difficult and time-consuming
Solution Approach 1:
The patent applies the dynamics principle by making the bristle frames movable rather than fixed. The frames are connected to the handle via cantilevers that allow the frames to bend and move away from each other when force is applied, enabling easy access for hair removal. This dynamic structure transforms the static, difficult-to-clean conventional brush into one where the bristles can actively separate to facilitate cleaning.
Solution Approach 2:
The patent segments the bristle structure into multiple independent frames (typically three frames) that can move relative to each other. Each frame holds bristles and can be independently manipulated. This segmentation allows users to separate the frames to access and remove accumulated hair, making the cleaning process much easier compared to conventional fixed-bristle designs.
2Ease of operation
If manual hair removal techniques are used (comb dragging or finger pinching), then hair can be removed from the brush, but significant manual effort and additional instruments are required
Solution Approach 1:
The patent implements self-service by designing the brush structure itself to facilitate hair removal without requiring external tools. The movable frames with cantilevers allow users to simply use their fingers to pull the frames apart and remove hair directly from between the bristles. The brush's own structure provides the mechanism for its own maintenance, eliminating the need for separate cleaning instruments.
3Reliability
If accumulated hair is not removed from the brush, then the brush remains in use, but the brush becomes unsanitary and less effective
Solution Approach 1:
The dynamic frame structure enables easy periodic cleaning to maintain sanitary conditions and brush effectiveness. By allowing frames to move apart, users can regularly remove accumulated hair before it creates unsanitary conditions or reduces brushing effectiveness, making maintenance a simple and frequent task rather than a difficult occasional chore.

Function Achieved in This Case
Facilitates rapid and effortless removal of hair fibers, maintaining the brush's effectiveness and extending its useful life while avoiding the need for additional tools or frequent replacements.
Implementation Method 1
handles with frames connected thereto through cantilevers that provide the ability of the frames to bend relative to the handle and to at least some of the other frames

AI summary
A hair brush that permits quick and easy removal of hair has a handle attached to a head. The head is made up of at least two frames that are mounted to the handle through cantilevers that permit movement of the frames relative to one another. The bristles are mounted to the frames, preferably in single rows. A force applied to one frame moves that frame relative to the other frame and the handle, thereby permitting the user to reach between the frames to remove any hair that is caught in the bristles. The brush allows a gap between the bristles to be enlarged, thereby making removal using human fingers much easier. Repeated movement and return of the frames to their resting position can cause the hair fibers to work away from the bristle bases and make removal much easier.
