Hair Clipper Comb Attachment With Finger Guide Depression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional comb attachments for hair clippers often require awkward finger pressure for secure installation, lacking a clear guidance for proper pressure application, which can lead to misplacement and improper attachment.
Innovation Solution
A comb attachment design featuring a depression on the top surface with a surrounding ridge, a cantilevered flexible clip, and arch-shaped arms that accommodate the thumb or finger, allowing easy alignment and secure attachment to the hair clipper blade with a flexible mechanism for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional comb attachments use side walls and grooves for securing, then the attachment is secured to the blade, but finger pressure is misplaced making attachment awkward
Solution Approach 1:
A finger guide element is introduced as an intermediary component between the user's finger and the comb attachment. This guide element channels and directs the applied pressure to the correct location on the attachment mechanism, ensuring proper engagement while making the operation intuitive and easy for the user
Solution Approach 2:
The attachment mechanism is designed to be self-aligning through the finger guide element, which automatically directs the user's pressure to the correct engagement point. This eliminates the need for precise manual positioning by the user, allowing the system to guide itself into proper attachment
2Ease of operation
If the comb attachment uses a flexible clip mechanism, then easy installation and removal are achieved, but stress is applied to the attachment during use
Solution Approach 1:
The finger guide element is designed to pre-position and align the comb attachment with the blade before the flexible clip engages. This preliminary alignment action ensures that the attachment is properly positioned prior to securing, distributing stress more evenly and preventing misalignment forces that would create excessive stress during normal use
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 secure and effortless attachment of the comb to the hair clipper blade by guiding the user's thumb or finger to the correct pressure point, ensuring proper alignment and reducing stress on the attachment, making the process more intuitive and stress-free.
Implementation Method 1
a flexible clip that snaps over the back of the stationary blade to secure the comb attachment in place

AI summary
A comb attachment (16) for a hair clipper (10) includes a base (32) having a depression (50) adjacent a back edge (38) of the attachment and a flexible clip (52) extending outwardly from the back edge. The depression locates a user's finger or thumb when pressing the base until the clip flexes around the edge of the blade. The comb attachment is removed by pulling the clip back around the blade. The flexible clip can be a cantilever having two spaced arch-shaped arms (54) extending from the base and secured to each other at their cantilevered ends by a cross-member (56). The bottom surface of the cross-member can be angled to facilitate release of the clip and removal of the attachment.
