Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional mascara brush structure is used, then the device is simple, but the flexibility during application and formula capacity are limited
Solution Approach 1:
The mascara brush employs a dynamic closed loop structure where the inner blade and outer blade are connected to form a flexible loop that can deform and adapt during application. This dynamic configuration allows the brush to follow the curvature of eyelashes while maintaining structural integrity, resolving the contradiction between flexibility and simplicity.
Solution Approach 2:
The brush is segmented into multiple functional components including the inner blade, outer blade, applicator elements, and reinforcement structure. This segmentation allows each component to perform its specific function while collectively providing both flexibility and formula capacity without excessive overall complexity.
2Quantity of substance
If a traditional mascara brush structure is used, then the device is simple, but the quantity of formula deposited in one application is limited
Solution Approach 1:
The inner blade is nested within the outer blade to form a closed loop structure, creating internal space for formula accumulation. This nested configuration maximizes the formula capacity within the brush structure without significantly increasing external dimensions or complexity.
Solution Approach 2:
The closed loop structure utilizes three-dimensional space efficiently by creating a volumetric formula reservoir rather than a flat surface. This dimensional approach allows greater formula capacity while maintaining a compact brush profile.
3Volume of stationary object
If the inner blade is positioned closer to the main axis, then the closed loop structure is more compact, but the space for formula accumulation is reduced
Solution Approach 1:
The patent optimizes the radial position of the inner blade as a critical parameter, positioning it at a distance from the main axis that balances loop compactness with formula accumulation space. This parameter optimization resolves the geometric contradiction by finding the optimal intermediate position.

AI summary
A mascara brush extending along a main axis and having at least one branch equipped with applicator elements. At least one branch includes a primary branch having an inner blade an outer blade meeting in such a way as to form a closed loop, and the inner blade is located at a distance from the main axis which is non-zero and less than a distance from the outer blade to the main axis.
