Hair-increasing device knotting method for natural hair flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair-increasing devices using net bases or rib-type frames face challenges in achieving natural hair flow, as the linear members restrict hair direction, leading to visibility issues, looseness of knots, and a lack of volume, limiting styling freedom and creating a less-than-thick appearance.
Innovation Solution
A hair-increasing device where hair is knotted with one end portion standing upright and the other end portion extending along the linear member, using a specific knotting method involving multiple loops to secure the hair tightly, ensuring the linear member is hidden and providing a rich voluminous appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hair is knotted to linear members arranged in matrix or diagonal direction using conventional planting methods, then hair can be secured to the net base or hair-secured frame, but hair flow is restricted to directions orthogonal to the linear members, making backward hair flow difficult
Solution Approach 1:
The patent inverts the conventional knotting approach by having one end portion of hair extend upright from the knot (perpendicular to linear member) while the other end portion extends along the linear member. This inversion allows hair to be secured to linear members arranged in any direction while achieving natural backward hair flow and multiple styling directions simultaneously.
2Reliability
If conventional knotting methods are used to attach hair to linear members, then hair can be secured, but the linear members remain visible and the appearance is less natural
Solution Approach 1:
The patent applies different spatial orientations to different portions of the same hair: one end portion extends upright from the knot to provide volume and natural appearance, while the other end portion extends along the linear member to conceal it. This local differentiation in hair orientation simultaneously achieves reliable hair securing and natural appearance by hiding the linear members.
3Quantity of substance
If hair is knotted densely to linear members using conventional methods, then hair amount can be increased, but hair lacks volume and appears thin due to lying flat
Solution Approach 1:
The patent adds a vertical dimension to hair orientation by having one end portion extend upright from the knot perpendicular to the linear member, while the other end portion extends horizontally along the linear member. This dimensional differentiation creates natural hair volume and thickness appearance while maintaining dense hair attachment, solving the problem of flat-lying hair.
4Ease of manufacture
If conventional planting methods are used, then hair can be attached to the base, but knots tend to loosen over time requiring additional fixing processes
Solution Approach 1:
The patent creates a composite knot structure where one end portion of hair extends upright and the other end portion extends along the linear member. This composite configuration distributes mechanical stress differently compared to conventional single-direction knotting, preventing knot loosening and eliminating the need for additional resin coating fixing processes.

AI summary
This invention relates to a hair increasing device that improves the freedom of hair styles and, is constituted in such a manner that each hair is knotted to a rib constituting a hair-secured frame with one end portion being twice wound, and the other end portion being once wound and pulled out thereafter. The one end portion of the tied hair is supported so as to stand upright with regard to a rib, and the other end portion is knotted so as to extend longitudinally on and along a rib, and thereby hair flow is formed in the longitudinal direction on a plurality of ribs so that the plurality of ribs is covered and hidden, and becomes hardly visible. Hence the rib or wig base linear member is hardly visible, the knot does not loosen, and the hair increasing device provides a rich voluminous appearance and allows versatility of hair styles.
