Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional cosmetic containers are used with single structure, then manufacturing is simple, but aesthetic appeal and fashionability are insufficient
Solution Approach 1:
The cosmetic container is divided into multiple components: a base container body and a separate patch component. The patch is further segmented into multiple regions (first region with first pattern, second region with second pattern, third region with third pattern) that can be independently designed and manufactured. This segmentation allows complex aesthetic patterns to be created while keeping each individual component relatively simple for manufacturing.
Solution Approach 2:
The patch uses composite material structure combining different plastic materials with distinct surface patterns. Each region of the patch can have different material properties and surface characteristics, allowing the container to achieve high aesthetic appeal through material composition rather than complex single-material structures.
2Reliability
If traditional materials are used for cosmetic containers, then manufacturing cost is low, but wear-resistance and durability are insufficient
Solution Approach 1:
The patch is manufactured from plastic materials selected for their superior wear-resistance and durability properties. By using composite material construction with multiple plastic regions, the patch achieves enhanced reliability and protection for the cosmetic container while maintaining compatibility with standard injection molding manufacturing processes.
Solution Approach 2:
The invention changes the material parameters by selecting plastic materials with specific properties for the patch, improving wear-resistance and durability. The surface patterns are also parameterized with specific geometric characteristics (protrusions, recesses, textures) that can be controlled during injection molding to achieve desired aesthetic and functional properties.
3Shape
If leather-like appearance is achieved through traditional methods, then aesthetic appeal is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patch implements local quality by creating different surface patterns in different regions. The first region has a first pattern, the second region has a second pattern, and the third region has a third pattern. Each region can be optimized for specific aesthetic effects while maintaining overall leather-like appearance. This localized approach achieves high aesthetic appeal through pattern variation rather than complex global structure.
Solution Approach 2:
The patch uses injection molding to copy leather surface patterns and textures into plastic material. By creating mold cavities that replicate leather grain and surface characteristics, the invention produces leather-like appearance directly during manufacturing, eliminating the need for separate leather processing steps and reducing overall manufacturing complexity.
4Adaptability or versatility
If single-color container design is used, then manufacturing is simple, but fashionability and consumer appeal are insufficient
Solution Approach 1:
The patch introduces asymmetry and variety through different patterns in different regions. The first pattern, second pattern, and third pattern can have different geometric characteristics, orientations, and densities, creating visual interest and fashionability. This asymmetric pattern distribution enhances consumer appeal while maintaining manufacturing simplicity through single-step injection molding.

AI summary
A patch for a cosmetic container and a mold for manufacturing the patch are provided. The patch for the cosmetic container includes a patch substrate formed integrally by a plastic material through injection molding, where the patch substrate includes a first surface and a second surface that are opposite to each other; the first surface includes bumps and recesses that are arranged alternately; a projection of the recess on the second surface is a coupling portion; and the coupling portion is configured to couple the patch and the cosmetic container. The patch for the cosmetic container has a leather-like appearance and a leather touch. By attaching to an outer surface of the cosmetic container, the patch for the cosmetic container not only protects the container, but also gives people a leather impression to improve the product grade.
