Hair Clip With Guide Loop And Pivot Finger
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 and design limitations.
Innovation Solution
A hair clip design featuring a pivot connection between upper and lower clip pieces with a coil spring, a finger for holding hair in a bundled state, and a guide loop to prevent hair from entering the joint portion, enhancing the hair clipping force and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the clip pieces are made long and narrow to form a lever, then the hair can be clipped near the connecting pin area, but the elastic force deteriorates in the area away from the connecting pin
Solution Approach 1:
The upper clip piece is divided into two functional parts: the main clip piece for leverage and a separate finger extension for additional hair engagement. This segmentation allows the long clip piece to maintain leverage while the finger provides localized gripping force at the distal end, compensating for the deteriorated elastic force in that region.
Solution Approach 2:
The finger acts as an intermediary element between the upper clip piece and the hair. It is connected to the upper clip piece through a pivot connection, allowing it to independently engage and hold hair in bundled form, thereby compensating for insufficient elastic force at the distal end of the long clip piece.
2Length of moving object
If the clip pieces are long and narrow, then they can form a lever mechanism, but they cannot clip hair in a gathered or bundled form
Solution Approach 1:
The upper clip piece is designed to perform multiple functions: it provides the lever mechanism for mechanical advantage while simultaneously supporting a finger extension that can hold hair in bundled or gathered forms. This multi-functionality allows a single component to address both the leverage requirement and the versatile hair holding requirement.
Solution Approach 2:
The finger is connected to the upper clip piece through a pivot connection, adding a rotational degree of freedom. This allows the finger to move independently and adapt to different hair configurations (gathered or bundled), enabling the clip to handle various hair styles beyond what a simple long clip piece could achieve.
3Device complexity
If the conventional hair clip design is used, then it is simple in structure, but the hair clip falls off easily during head movement
Solution Approach 1:
The finger is connected through a pivot connection rather than being rigidly fixed, allowing it to dynamically adjust its position and angle. This dynamic capability enables the finger to adapt to head movements and maintain secure hair holding, improving reliability without significantly increasing structural complexity.
Solution Approach 2:
The finger is nested within or integrated with the upper clip piece structure, with the guide loop providing an additional nested element to prevent hair from entering the joint portion. This nested arrangement allows multiple functional elements to be compactly integrated, maintaining simplicity while enhancing holding stability.
4Adaptability or versatility
If a finger is added to hold hair in bundled form, then hair holding capability is improved, but the device complexity increases
Solution Approach 1:
The finger is merged with the upper clip piece through a pivot connection, combining two functional elements into a integrated assembly. The guide loop is also merged with the finger structure, creating a compact unit that provides multiple functions (hair holding and hair guidance) without requiring separate independent components, thereby limiting the increase in device complexity.

AI summary
A hair clip is provided. The hair 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 and 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.
