Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D simulation of lashes is implemented with multiple modifiable parameters, then the ability to visualize and evaluate different lash styles and treatments is improved, but the device complexity increases
Solution Approach 1:
The patent creates virtual 3D copies of eyelashes with various parameters (length, curvature, thickness, color) that can be manipulated to simulate different styles and treatments. These digital models replicate real lash behavior under different conditions without requiring physical prototypes or multiple treatment applications.
Solution Approach 2:
The patent transitions from 2D images to 3D virtual models of eyelashes, adding depth and spatial dimensionality. This enables realistic simulation of how lashes respond to treatments from multiple viewing angles and provides more accurate visualization of treatment effects.
2Ease of operation
If multiple simulation parameters are made modifiable by users, then the ease of operation for customizing lash appearance is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal control interface that handles multiple lash parameters (length, curvature, color, thickness) through a single integrated system. This multi-functional approach allows users to adjust various aspects of lash appearance using one device with standardized controls, rather than requiring separate tools for each parameter.
Solution Approach 2:
The patent enables users to modify numerical parameters of virtual lashes (such as length in millimeters, curvature radius, color values) directly through the interface. By allowing direct parameter adjustment, the system provides precise control over lash appearance while maintaining operational simplicity through clear parameter naming and intuitive adjustment mechanisms.
3Measurement precision
If the simulation accounts for product application and treatment effects, then the measurement precision of treatment evaluation is improved, but the device complexity increases
Solution Approach 1:
The patent pre-programs various treatment effects and product formulations into the simulation model. Common treatments (mascara application, eyelash curling, perming) and their effects are prepared in advance within the system, allowing users to select from predefined treatment scenarios that automatically apply appropriate physical and chemical transformations to the virtual lashes.
Solution Approach 2:
The patent replaces physical treatment applications with computational models that simulate the effects of products and treatments. Instead of requiring actual mascara application or heat treatment devices, the system uses mathematical algorithms to replicate how these treatments would affect lash appearance, enabling precise evaluation without complex physical equipment.

AI summary
A method for simulating the appearance of at least one fringe of lashes may include generating, based on at least one value of at least one simulation parameter that is modifiable by a user, at least one 3D image of the at least one fringe of lashes. The at least one 3D image may be generated from a multizone simulation of the fringe. The multizone simulation may allow the user to define values of simulation parameters specific to at least two different zones of the at least one fringe of lashes.
