Hair Replacement Strip with Segmented Fixing Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing hair replacement parts to sparse or thinning hair are difficult, require special skill, and can be painful or unsatisfactory, especially when hair loss is significant, leading to an unsightly and uncomfortable fit.
Innovation Solution
A method involving a strip with a fixing section and fastening section attached to the underside of the hair replacement part, allowing hair bundles to be pulled through holes and secured with a clip, distributing forces evenly to prevent hair loss and providing a comfortable, secure fit, with the option for self-correction and easy re-tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the strip is attached close to the scalp to ensure good fit, then the fit of the hair replacement part is improved, but painful tension appears in the skin and there is a risk of hair being pulled out
Solution Approach 1:
The strip is divided into a fixing section with holes and a fastening section. The fixing section distributes attachment forces through multiple holes across multiple hair bundles, while the fastening section provides secure closure. This segmentation allows the attachment to be close to the scalp for good fit without concentrating harmful forces on single hair bundles.
Solution Approach 2:
Multiple hair bundles are pulled through the holes and prepared for fixation before the fastening section is closed. This preliminary arrangement of hair bundles allows the forces to be distributed and balanced before final securing, preventing painful tension and hair loss while ensuring good fit.
2Object-affected harmful factors
If the strip is attached far from the scalp to avoid pain and hair loss, then the risk of hair being pulled out is reduced, but the fit of the hair replacement part becomes unsatisfactory
Solution Approach 1:
The strip structure with multiple holes in the fixing section allows attachment to be positioned close to the scalp while distributing forces across multiple hair bundles. This segmentation enables close-to-scalp attachment (good fit) without the harmful concentration of forces that would cause hair loss.
3Reliability
If knots are used to attach the hair replacement part to sparse hair, then attachment is achieved, but the process is so difficult that the wearer cannot do it himself and requires considerable labor and skill
Solution Approach 1:
The strip with pre-formed holes and the simple pull-through mechanism enable the wearer to attach the hair replacement part themselves without requiring professional skill. The process of pulling hair through holes and securing with the fastening section is simple enough for self-service while providing reliable attachment.
Solution Approach 2:
The complex knot-tying process is replaced by extracting the essential function of attachment and implementing it through a simpler pull-through mechanism with a fastening section. This eliminates the need for skilled knot-tying while maintaining secure attachment.
4Reliability
If the strip is used with sufficient hair volume, then the strip is sufficiently fixed and covered, but the method fails when hair loss is significant and only very little residual hair is present
Solution Approach 1:
The strip is divided into multiple holes in the fixing section, allowing multiple separate hair bundles to be pulled through and distributed across the attachment area. This segmentation enables secure fixation even when total hair volume is low, as long as multiple small bundles can be gathered and distributed through the holes.
Solution Approach 2:
Instead of requiring sufficient overall hair volume, the method gathers and uses multiple small hair bundles from different local areas. Each hole receives a small bundle, and the collective effect of multiple distributed bundles provides secure fixation even when total hair volume is limited.
5Ease of manufacture
If the fixing section is visible, then the attachment method is simple, but the strip becomes perceptible and disturbs the appearance
Solution Approach 1:
The fixing section with holes is nested within the hair bundles that are pulled through it, and both are covered by the hair replacement part base. This nesting arrangement hides the fixing section from view while maintaining the simple pull-through attachment mechanism.
Solution Approach 2:
The fixing section is designed to be optically concealed by the hair replacement part base, which has a dark coloring that matches the appearance of natural hair. This color matching makes the visible portions of the fixing section imperceptible, eliminating visual disturbance while keeping the attachment method simple.

AI summary
The method involves placing a strip (5) with a fixing section at a lower side of a scalp hair replacement part (1), so that the fixing section is completely covered by the replacement part. The replacement part is folded based on the fixing section, and a hair bundle (6) drawn through holes (4) is suspended and/or released and/or locked in a space between the fixing section and the replacement part. The folded section of the replacement part is lowered adjacent to the fixing section, so that the fixing section is completely covered and fixed in the replacement part. An independent claim is also included for a device for removably attaching a flexible scalp hair replacement part to remaining hair of a person.
