Wig Net Cap Sewing Process for Ergonomic Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wig products have difficulty fitting the user's head due to the rigidity of their hairnets, making them inconvenient to wear.
Innovation Solution
A novel wig net cap sewing process that combines a first and second hairnet with elastic nets and fixing bands, allowing for a more flexible and ergonomic fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional rigid hairnet is used to maintain the spherical shape of the wig, then the structural stability is improved, but the ease of operation deteriorates because it is difficult to fit with the user's head
Solution Approach 1:
The hairnet is divided into multiple segments including a first hairnet, a second hairnet, and an extension net that can be separately sewn and assembled. This segmentation allows each part to be more flexible during fitting while maintaining overall structural stability when combined.
Solution Approach 2:
The patent introduces elastic nets (first elastic net, second elastic net, third elastic net) that provide dynamic flexibility to the wig cap structure. These elastic components allow the rigid-looking hairnet to adapt dynamically to different head shapes and sizes, resolving the contradiction between structural stability and ease of fitting.
2Ease of operation
If multiple components are combined to improve flexibility and fit, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Multiple hairnet components (first hairnet, second hairnet, extension net) and elastic nets are merged into a single integrated wig cap structure through sewing. This combining approach maintains the flexibility benefits of multiple components while presenting a unified, manageable final product that does not appear overly complex.
Solution Approach 2:
The extension net serves multiple functions: it extends the coverage area of the hairnet, provides additional flexibility for fitting, and acts as a connecting element between different parts of the wig cap. This multi-functionality reduces the need for separate specialized components, thereby managing complexity.
3Ease of operation
If elastic nets and fixing bands are added to improve flexibility, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The elastic nets and fixing bands are pre-attached to the hairnet components during the manufacturing process. This preliminary action ensures that these flexible elements are properly positioned and secured before the final assembly, reducing the precision requirements during subsequent fitting and wear operations.
Solution Approach 2:
Different regions of the wig cap have different levels of flexibility and structural requirements. The patent applies elastic nets in specific areas where flexibility is needed for fitting, while maintaining more rigid structures in areas requiring stability. This localized approach to quality allows manufacturing precision to be focused where most needed.
