Innovation Solution
A cosmetic product featuring a three-dimensional woven fabric impregnation material with a vertically layered structure, including a first surface region, a second surface region, and a pillar region connected by Z-yarns, which allows for high impregnation rates, easy pattern formation, and quick injection of cosmetic materials, with a rim portion to prevent debris and enhance external appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If porous foam is used as impregnation material, then cosmetic material can be discharged easily, but it is difficult to inject cosmetic material and channels are damaged when forming surface patterns
Solution Approach 1:
The patent changes the structural parameters of the impregnation material by using three-dimensional woven fabric with controlled porosity and interstices instead of conventional porous foam. This allows cosmetic material to be injected through larger gaps between yarns without clogging, while still enabling easy discharge through controlled pore structures in the fabric.
Solution Approach 2:
The patent uses a composite structure combining three-dimensional woven fabric with specific yarn arrangements and interstices, creating a material that兼具 injection accessibility and discharge efficiency. The composite structure of warp and weft yarns with controlled spacing provides both large injection channels and effective cosmetic material release.
2Shape
If heating and pressing method is used to form surface pattern on porous foam, then aesthetic appearance is achieved, but channels through which cosmetic material flows are damaged
Solution Approach 1:
The patent changes the material parameters from porous foam to three-dimensional woven fabric, which has inherent structural stability. The woven structure maintains its integrity under heating and pressing, allowing surface patterns to be formed without damaging the cosmetic material flow channels, as the fabric's interstices remain open despite surface compression.
Solution Approach 2:
The patent introduces a third dimension to the fabric structure with raised patterns and recesses created through controlled compression of the three-dimensional woven structure. This dimensional change allows surface aesthetics to be achieved while maintaining the internal channel structure for cosmetic material flow through the fabric's depth.
3Productivity
If three-dimensional woven fabric is used instead of porous foam, then injection and discharge of cosmetic material is facilitated, but surface pattern formation and external appearance may be compromised
Solution Approach 1:
The patent applies local quality by creating different structural characteristics in different regions of the fabric. The bulk of the fabric maintains open interstices for efficient cosmetic material injection and discharge, while specific surface regions are compressed or patterned to create aesthetic surface designs. This localized differentiation allows both functional and aesthetic requirements to be met simultaneously.
Solution Approach 2:
The patent utilizes the three-dimensional nature of the woven fabric to create surface patterns through controlled compression and raising of specific areas. By manipulating the fabric in the third dimension (thickness/height), aesthetic surface patterns are created while maintaining the internal porosity and interstices necessary for efficient cosmetic material flow.
