Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional cosmetic compact case accommodates a cosmetic substance and puff, then it can store cosmetic products, but it becomes bulky and deforms when carried in bags
Solution Approach 1:
The compact case is divided into multiple functional sections: an upper compartment for cosmetic product storage, a lower compartment for brush storage, and a mirror section. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness, resolving the contradiction between storage capacity and compact size.
Solution Approach 2:
The brush unit is designed to be inserted into and stored within the compact case body, with the brush handle fitting into a dedicated storage cavity. This nesting arrangement allows the brush to be accommodated within the existing compact structure without increasing the overall volume, thus maintaining small size while adding functional elements.
2Volume of moving object
If the compact case is designed to be compact in size, then it is easy to carry, but a brush or mirror cannot be built in
Solution Approach 1:
The compact case is divided into multiple functional sections: an upper compartment for cosmetic product storage, a lower compartment for brush storage, and a mirror section. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness, resolving the contradiction between storage capacity and compact size.
Solution Approach 2:
The brush storage function is integrated into the vertical structure of the compact case by utilizing the space between the upper and lower plates. The brush unit can be inserted through the open portion of the side peripheral wall and stored in the slide storage part, effectively using three-dimensional space to accommodate additional functionality without increasing the overall footprint.
3Ease of operation
If a general cosmetic compact case is opened by up and down rotation, then it can access cosmetics, but it requires both hands and is inconvenient to use
Solution Approach 1:
The cover is designed with a hinge coupling part that allows it to rotate relative to the case body, transitioning from a closed position to an open position. This dynamic mechanism enables single-handed operation by leveraging the rotational movement of the cover, eliminating the need for two-handed manipulation while maintaining secure closure when closed.
Solution Approach 2:
The hinge coupling part acts as an intermediary mechanism between the cover and case body, enabling controlled rotational movement. This intermediary component facilitates smooth transition between closed and open states while maintaining structural integrity, allowing easy single-handed operation without requiring complex multi-component mechanisms.
4Ease of operation
If the compact case includes a brush unit with sliding mechanism, then it provides convenience in use, but it increases device complexity
Solution Approach 1:
The brush unit is designed with a sliding mechanism that allows it to move between a retracted position (stored within the case body) and an extended position (accessible from the outside). This dynamic capability enables convenient brush access while maintaining a compact form when closed, and the sliding action can be easily controlled by the user without requiring complex actuation mechanisms.
Solution Approach 2:
The brush unit is extracted as a separate, movable component from the main case body structure. It can be inserted through the open portion of the side peripheral wall and stored in the slide storage part, allowing it to be independently manipulated. This extraction approach simplifies the overall mechanism by isolating the brush storage function from the main case structure, reducing the complexity of integration.

AI summary
Proposed is a portable slide-type cosmetic compact case including: a case body including an upper plate, which has a cosmetic product accommodation part in which cosmetics are accommodated, a lower plate spaced from the upper plate so as to face same, and a side peripheral wall connecting the upper plate and the lower plate and having an open portion, wherein the upper plate, the lower plate and the open side peripheral wall form a slide storage part; a brush unit which is a brush, that is used while the cosmetic product is applied thereon, and which slides in the slide storage part through the open portion in the side peripheral wall so as to be inserted therein and attached/detached thereto/therefrom; and a cover which covers the cosmetic product accommodation part from the upper side of the upper plate and which is coupled to the case body.
