Wig Base Elastic Modulus Segmentation for Facial Skin Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wigs fail to effectively reduce facial sags and wrinkles due to complications in attachment and insufficient skin lifting, often causing discomfort or inadequate sag reduction, especially around the temple and eye areas.
Innovation Solution
A wig base with a combination of first and second elastic portions having different moduli of elasticity, along with a position holding portion, is designed to be placed strategically on the head, providing sufficient flexibility and elasticity for effective sag reduction and comfortable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single rubber with high modulus of elasticity is used to pull up the skin, then the skin lifting function is improved, but the wearer feels pain due to strong pulling
Solution Approach 1:
The elastic body is divided into first and second elastic portions with different moduli of elasticity. The first elastic portion (with higher modulus) provides strong skin lifting force, while the second elastic portion (with lower modulus) reduces the harmful pulling effect on the wearer's skin, thus resolving the contradiction between lifting effectiveness and wearer comfort.
Solution Approach 2:
Different portions of the elastic body are assigned different local qualities (moduli of elasticity) based on their functional requirements. The first elastic portion has higher elasticity for effective skin lifting, while the second elastic portion has lower elasticity for comfortable wear, allowing each region to optimize its performance for its specific function.
2Object-affected harmful factors
If a single rubber with low modulus of elasticity is used to pull up the skin, then the wearer comfort is improved, but the skin is not pulled up sufficiently
Solution Approach 1:
The elastic body is segmented into portions with different elastic properties. The second elastic portion provides comfort with lower modulus, while the first elastic portion ensures sufficient skin lifting with higher modulus, thus resolving the contradiction between comfort and lifting effectiveness.
3Strength
If a flexible body is connected to the cap net, then the skin lifting function is improved, but the handling for attaching the wig becomes complicated
Solution Approach 1:
The first and second elastic portions are integrated into a single elastic body that is directly attached to the wig base, eliminating the need for separate connection to the cap net. This merging simplifies the attachment process while maintaining the skin lifting function through the differentiated elastic portions.
4Device complexity
If a single rubber is used to provide expansion and contraction function, then the device complexity is reduced, but the skin lifting function is insufficient especially around the temple and tail of eye
Solution Approach 1:
The elastic body is segmented into first and second elastic portions with different moduli of elasticity, allowing differentiated skin lifting performance across different facial regions. This segmentation enables effective lifting around sensitive areas like the temple and tail of eye while maintaining reasonable structural complexity.
Solution Approach 2:
Different local qualities (moduli of elasticity) are assigned to different portions of the elastic body to match the specific skin lifting requirements of different facial regions, particularly enhancing effectiveness around the temple and tail of eye areas.
