Hair Clip With Finger And Guide Loop For Bundled Hair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair clips fail to securely hold hair in a gathered or bundled form and tend to fall off during head movement, due to inadequate elastic force distribution and design limitations.
Innovation Solution
A hair clip design featuring a pivot-connected upper and lower clip piece with a finger and guide loop, where the finger performs a joint action to enhance clipping force and prevent hair from entering the joint portion, ensuring secure holding of hair in a bundled state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional clip pieces are used with a spring, then the hair can be clipped near the connecting pin area, but the elastic force deteriorates in the area away from the connecting pin and the hair cannot be clipped firmly enough
Solution Approach 1:
The invention divides the clipping function into two independent components: the original spring-based clip pieces for general clipping, and an additional finger component with its own elastic element for reinforcing the distal area. This segmentation allows each component to address specific zones, solving the problem of deteriorating elastic force away from the connecting pin.
Solution Approach 2:
The finger acts as an intermediary element between the spring mechanism and the hair in the distal area. It transmits and concentrates the elastic force specifically to the area where conventional clip pieces fail to provide sufficient holding force, thereby mediating the force distribution to achieve firm clipping throughout the entire clip piece length.
2Device complexity
If conventional clip pieces are used, then the structure is simple, but the hair cannot be held in a gathered or bundled form and the clips fall off easily during head movement
Solution Approach 1:
The invention segments the clipping system into traditional clip pieces and an added finger component, allowing the finger to specifically address bundled hair holding while the main clip pieces maintain their simple structure for general clipping function.
Solution Approach 2:
The finger is pre-positioned and connected to the clip piece to proactively prevent hair from entering the joint portion before problematic situations occur. This preliminary positioning ensures that even during head movement, the hair remains securely held in a bundled form without requiring complex adjustment mechanisms.
3Ease of operation
If the clip pieces are long and narrow to form a lever, then the connecting pin serves as a supporting point, but the elastic force of the spring deteriorates in the area away from the connecting pin
Solution Approach 1:
The finger serves as a force intermediary that receives elastic force from the spring through the clip piece and redistributes it to the distal area. This intermediary mechanism preserves the lever mechanism's ease of operation while correcting the uneven force distribution caused by the long and narrow clip piece geometry.
Solution Approach 2:
The invention changes the force distribution parameter by introducing the finger with its own elastic element, transforming the single-point elastic force application near the connecting pin into a distributed force system that maintains adequate clipping force throughout the entire length of the clip piece.
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 hair clip effectively secures hair in a gathered or bundled form, preventing it from falling off even with head movement, by combining the original clipping force with the reinforced force of the finger, maintaining safety and beauty.
Implementation Method 1
the upper and lower clip pieces are pressed against each other by the elasticity of the spring
Implementation Method 2
a pivot connection that has a hinge pin and a coil spring

AI summary
A hair clip is provided. The hair clip has a lower clip piece and an upper clip piece connected through a pivot connection with a hinge pin and coil spring. The upper clip piece has a bottom portion that defines a concavity portion for defining a hair holding space to hold hair in a bundled state. A finger is connected to the upper clip piece through a pivot connection and for holding hair in a bundled state. A guide loop is connected to a rear end portion of the finger through a pivot connection. The guide loop prevents hair from entering a joint portion defined by the finger and the upper clip piece.
