Wig Base With Adjustable Nape Pad For Flat Occipital Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wigs struggle to provide a secure and comfortable fit for individuals with flat occipital regions, often slipping or falling off, and require time-consuming and costly custom-made solutions.
Innovation Solution
A wig base or cap featuring a bag-shaped pad portion filled with polyurethane foam, which is designed to contact the nape hollow of the occipital region, providing adjustability and a non-slip surface for improved fit and wearability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a ready-made wig base is used, then the production time and cost are reduced, but the fit feeling and wearability deteriorate for persons with flat occipital regions
Solution Approach 1:
The wig base is divided into a base cap and a separate pad portion that can be independently adjusted. The pad portion is filled with polyurethane foam to create a customizable shape that fits the occipital region, while the base cap remains a standard ready-made component. This segmentation allows the ready-made base to be enhanced with a customized fitting element.
Solution Approach 2:
The pad portion is made adjustable and removable, allowing the wearer to modify the fit dynamically. The polyurethane foam filling can be adjusted in quantity and distribution to accommodate different head shapes, and the pad can be removed or repositioned to achieve optimal fit feeling without requiring a completely custom-made wig base.
2Reliability
If a custom-made wig base is used, then the fit feeling and wearability are improved, but the production time and cost increase
Solution Approach 1:
By separating the customizable pad portion from the standard base cap, the invention allows only the necessary portion to be custom-made (the pad with foam filling) while the majority of the wig base remains a ready-made component. This reduces the overall production time and cost compared to completely custom-made wigs.
Solution Approach 2:
Customization is applied locally only to the pad portion where it is most needed (the occipital region), rather than customizing the entire wig base. This localized approach achieves improved fit feeling for persons with flat occipital regions while minimizing the time and cost investment required.
3Device complexity
If a conventional wig base without special pad structure is used, then the structure is simple, but the wearability deteriorates for persons with flat occipital regions
Solution Approach 1:
A specialized pad portion with polyurethane foam filling is added specifically to the occipital region of the wig base, providing enhanced wearability for persons with flat occipital regions. The rest of the wig base maintains its simple conventional structure, so the overall complexity increase is minimal while targeting the specific problem area.
Solution Approach 2:
The specialized pad portion is made as a separate, removable component rather than integrating it into the entire wig base structure. This segmentation maintains the simplicity of the base cap while adding the necessary functional element for improved wearability, and allows the pad to be easily adjusted or removed if needed.
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 solution enhances wearability and fit feeling by securely adhering to the head, allowing for easy adjustment to fit various head shapes, and providing a balanced and aesthetically pleasing appearance.

AI summary
Provided are: a wig base or a wig cap, which is capable of improving wearability and fit feeling to the head; and a wig including the wig base or the wig cap.A wig 100 includes a wig base 1 formed into a cap shape capable of covering the entire head from wearer's ears and nape, in which a bag-shaped pad portion 2 is integrally provided on an occipital region 6 of a back surface of this wig base 1. The bag-shaped pad portion 2 is formed into a substantially fan shape having a hollowed lower portion, and an inside of the pad portion 2 is able to be filled with polyurethane foam 8. At least a part of the pad portion 2 is sewn on the back surface of the wig base 1 so as to be located on a nape hollow 9 (a hollowed portion from the occipital region to the nape) of the wearer's occipital region, and is brought into contact with the nape hollow 9.
