Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hydro-colloidal patch is used, then moisture retention function is provided, but active ingredients for wound treatment or skin beauty are not contained
Solution Approach 1:
The patch is divided into multiple functional layers including base film, adhesive layer, and functional material layer. The functional material is applied only to specific regions through guide holes, creating segmented functional zones that provide both moisture retention and active ingredient delivery capabilities.
Solution Approach 2:
Different regions of the patch have different properties: the adhesive layer provides sticking force, the functional material layer provides treatment effects, and guide holes enable precise material placement. This local differentiation allows the patch to simultaneously provide moisture retention and active ingredient functions.
2Duration of action of stationary object
If cosmetic mask pack is used, then skin moisture is maintained, but adhesive force is rapidly reduced due to moisture evaporation
Solution Approach 1:
The mask pack is segmented into a moisture-retaining adhesive layer and a separate functional material layer. The adhesive layer maintains moisture to preserve adhesive force, while the functional material layer provides treatment effects without interfering with adhesion.
Solution Approach 2:
The adhesive layer acts as an intermediary between the skin and the functional material layer, maintaining moisture to preserve adhesive force while allowing the functional material to exert its effects on the skin.
3Adaptability or versatility
If functional material is applied to base patch, then wound treatment or skin beauty function is provided, but production capacity is reduced due to lengthy drying process
Solution Approach 1:
The base patch is prepared in advance with adhesive layer and guide holes formed before functional material application. This preliminary preparation allows for rapid functional material application and quick drying, significantly improving production capacity while maintaining functional effectiveness.
Solution Approach 2:
The guide holes create a porous structure that facilitates rapid evaporation and drying of the functional material. This porous design allows the functional material to be quickly applied and dried, maintaining high production capacity while providing wound treatment or skin beauty functions.
4Adaptability or versatility
If functional material is applied to base patch, then functional effects are provided, but product defect rate increases due to application inaccuracy
Solution Approach 1:
The guide film with guide holes acts as an intermediary between the functional material application system and the base patch. It ensures precise material placement by providing defined pathways and boundaries, thereby reducing application errors and defect rates while maintaining functional effectiveness.
Solution Approach 2:
The guide film may include visual indicators or color-coded regions that help operators or automated systems accurately align and apply functional material to the correct areas of the base patch, improving application precision and reducing defects.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus minimizes defect rates and maximizes production capacity by ensuring accurate application and rapid drying of functional materials on patches, enhancing their effectiveness for both medical and cosmetic uses.
Implementation Method 1
The drying section includes a heat supply unit for supplying heat to the functional material applied to the base patch. The base patch is converted into a finished patch in which the functional material is dried by the heat supplied from the heat supply unit
Implementation Method 2
The heat supply unit may be a near-infrared heater for supplying near-infrared radiant heat to the functional material applied to the base patch
