Solution Overview

Problem

Conventional puff manufacturing methods require separate lines for puffs and powder casings, making them inconvenient for users and manufacturers, as users need to carry both the puff and powder casing for application, and manufacturers must produce them separately.

Innovation Solution

A method involving laser-perforating and cutting puff fabric, shaping it into a base, compressing powder with a porous member to create a compact powder, and integrating it into the puff base, which is then covered with a sewn or adhesive cover, allowing for portable and easy use by eliminating the need for a separate powder casing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional puff manufacturing methods are used with separate puff and powder casing production lines, then manufacturing processes are well-established, but device complexity and user burden increase due to needing to carry both puff and powder casing separately

Engineering Contradiction:
Improveuser convenienceVSAvoidmanufacturing system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the puff body and powder casing into a single integrated unit. The puff fabric serves dual functions as both the applicator surface and the container for cosmetic powder. The handle is integrated directly into the puff structure, eliminating the need for separate carrying of puff and powder casing, thus improving user convenience while reducing overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The puff fabric is designed to perform multiple functions: it serves as the cosmetic application surface, the container for holding powder, and the structural body of the product. This multi-functionality eliminates the need for separate powder casing components, resolving the contradiction between ease of operation and device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If separate manufacturing lines are constructed for puffs and powder casings, then each component can be optimized independently, but manufacturing cost and production time increase

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidproduction speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The manufacturing process merges the production of puff body and powder casing into a single integrated process. The puff fabric is directly formed and sealed to contain powder, eliminating the need for separate manufacturing lines. This integration reduces manufacturing costs and accelerates production speed by removing intermediate assembly steps

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The puff fabric is pre-formed with the appropriate structure and size to directly contain the powder. The laser perforation and sealing processes are performed in advance during puff fabrication rather than as separate post-processing steps for powder casing assembly, improving manufacturing efficiency and productivity

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If puff fabric is made dense to maintain shape and structure, then structural stability is improved, but powder penetration and application performance deteriorate

Engineering Contradiction:
Improvepuff structure stabilityVSAvoidpowder application performance
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The puff fabric exhibits different structural properties in different regions: the outer surface and edge portions maintain higher density for structural stability and shape maintenance, while the inner surface contains laser-perforated holes that provide porosity for effective powder penetration and application. This local differentiation resolves the contradiction between structural stability and application performance

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Laser perforation creates a controlled porous structure within the puff fabric. These perforations allow cosmetic powder to penetrate through the fabric during application while the overall fabric density remains sufficient to maintain puff shape and structural integrity, balancing both requirements

Inventive Principle:
Principle #31Porous materials
