Dual-Knit Facial Cleansing Pad for Reusable Makeup Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing makeup from the face are inefficient and often result in makeup residue being difficult to clean from towels or tissues, rendering them unsuitable for other uses.
Innovation Solution
A facial cleansing pad with a pliant fabric body featuring a long pile knit finish on one surface and an openwork warp knit finish on the other, along with an inelastic edging to prevent stretching, allowing for effective and reusable makeup removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If towels or tissues are used to remove makeup, then makeup removal is achieved, but the towels become difficult to clean and unsuitable for other uses
Solution Approach 1:
The patent applies the disposable principle by creating a facial cleansing pad that is designed for single-use or limited-use. The pad body is constructed from absorbent material that can effectively remove makeup but is not intended to be washed and reused like traditional towels. After use, the pad is discarded rather than cleaned, eliminating the problem of makeup residue buildup that renders towels unsuitable for other purposes.
2Ease of operation
If a pliant fabric body with long pile knit finish is used, then makeup removal efficiency is improved, but the pad may stretch and lose its shape
Solution Approach 1:
The patent applies the composite materials principle by combining two different fabric constructions in a single pad structure. The pad body uses a pliant fabric with long pile knit finish on one surface for effective makeup removal, while the edging is constructed from a different material with specific elastic properties that provide structural stability. This composite construction allows the pad to maintain its shape during use while still providing the soft, effective cleaning surface needed for makeup removal.
Solution Approach 2:
The patent applies the local quality principle by giving different parts of the pad different properties. The central pad body is made with a pliant, long pile knit fabric that is soft and effective for makeup removal, while the peripheral edging is constructed from a different material with specific elastic characteristics that provide shape retention. This localized differentiation of material properties allows each part to perform its specific function optimally without compromising the other.
3Stability of the object's composition
If edging is sewn to the perimeter with stitching through both surfaces, then the pad maintains its shape, but the stitching may penetrate and damage the fabric structure
Solution Approach 1:
The patent applies the local quality principle by differentiating the construction method for different parts of the pad. The edging is attached to the pad body using stitching that is appropriate for each layer, ensuring that the stitching secures the edging effectively without penetrating through and damaging the delicate pad body fabric structure. This localized approach to stitching protects the structural integrity of the pad while maintaining the shape-stabilizing function of the edging.

AI summary
A facial cleansing pad includes a body constructed from a pliant fabric and having opposed first and second surfaces. The first surface has a long pile knit finish, preferably an openwork finish, and the second surface has a warp knit finish. The long pile knit finish extends beyond the first surface, and the warp knit finish has no height with respect to the second surface.
