Lip Categorizing Map Using Orthogonal Shape Indices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lip makeup fail to effectively categorize and correct lip forms based on their shape and size, leading to unattractive applications that do not consider the unique features of individual lips, particularly in modern women with fuller and thicker lips.
Innovation Solution
A method for categorizing lips using size and shape as indices, with a categorizing map composed of orthogonal coordinate axes representing lateral width, crests and trough form, bottom shape, contour type, and three-dimensional form, along with a makeup technique involving specific steps to adjust lip contours and a tool for applying makeup to achieve balanced and attractive lip shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing facial feature categorization methods are used, then the entire face can be categorized based on arrangement and contour shape, but the method cannot be applied to categorize lips only with their specific formal features
Solution Approach 1:
The patent segments the lip categorization process into distinct formal features (size, shape, three-dimensional form) and evaluates each independently using specific indices. This allows the lip categorization system to focus solely on lip characteristics without being constrained by entire face categorization methods, thereby improving adaptability while maintaining manageable complexity.
2Reliability
If lip makeup is applied without considering individual lip form features, then the makeup application process is simple, but the result is unattractive and does not correct lip form effectively
Solution Approach 1:
The patent implements preliminary evaluation of lip formal features (size index, shape index, three-dimensional form) before makeup application. This preliminary assessment allows the makeup process to be tailored to individual lip characteristics, ensuring attractive and form-correcting results while maintaining a systematic approach that does not overly complicate the application process.
3Measurement precision
If traditional lip categorization using only width and area indices is used, then the categorization process is simple, but formal differences between lips cannot be determined
Solution Approach 1:
The patent applies local quality by introducing specific formal feature indices (shape index for contour characteristics, three-dimensional form evaluation) that focus on particular aspects of lip morphology. This allows precise determination of formal differences in specific lip regions and characteristics without requiring complete reconstruction of the categorization system, thus improving measurement precision while controlling complexity.

AI summary
A lip categorizing method uses the size and shape of the lips as viewed from the front of the face as a first categorization index and the three-dimensional form of the lips as a second categorization index. The lip categorizing map is composed of a first coordinate axis showing the degree of the first categorization index and a second coordinate axis showing the degree of the second categorization index and has a coordinate system in which the first and second coordinate axes are orthogonal. It also generates makeup information for two-dimensionally correcting the lips of a subject based on preset reference by setting a plurality of points for determining the form features of lips on an image that depicts the lips, and judges the form features of the lips of the subject based on analytical values of the two-dimensional features of the lips measured from the set points.
