Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for guiding eyebrow shaping lack precision and user interaction, leading to inconsistent results in aesthetic enhancements such as microblading, ombre, nanostroking, tattooing, and other eyebrow modifications.
Innovation Solution
A system and method using projected light to guide eyebrow shaping by aligning curvilinear segments of eyebrow geometries with facial landmarks, allowing for real-time manual or automated adjustment and confirmation of target eyebrow geometries before applying aesthetic enhancements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional eyebrow shaping methods are used without projection systems, then the process is simple and quick, but precision and consistency of the eyebrow design are poor
Solution Approach 1:
A projection system is introduced as an intermediary device that displays target eyebrow geometry overlays on the user's face. This mediator enables precise alignment and customization of eyebrow shapes without direct physical contact, resolving the contradiction between precision and system complexity by using visual guidance rather than complex mechanical guidance tools.
Solution Approach 2:
The patent replaces traditional mechanical or manual eyebrow shaping guidance with an optical projection system. Instead of using physical templates or manual measurement tools, the system uses projected light displays to show target geometry, thereby achieving higher precision while keeping the overall system relatively simple and non-intrusive.
2Productivity
If automated eyebrow shaping is implemented without user interaction, then efficiency increases, but adaptability to individual user preferences and facial features decreases
Solution Approach 1:
The system incorporates feedback mechanisms where users can interact with the projected eyebrow geometry overlays, adjusting shapes, positions, and styles according to their preferences. The system responds to user input in real-time, allowing efficient automated processing while maintaining high adaptability to individual user wants and facial characteristics.
Solution Approach 2:
The eyebrow geometry overlays are dynamically adjustable rather than fixed. The system allows real-time modification of the projected shapes based on user feedback, enabling both efficient automated application and flexible adaptation to user preferences, thus resolving the contradiction between productivity and adaptability.
3Adaptability or versatility
If multiple eyebrow geometry options are projected simultaneously, then user choice and customization increase, but alignment precision and focus on specific target areas decrease
Solution Approach 1:
The projection system displays multiple eyebrow geometry options as separate, distinct overlays that can be individually selected and adjusted. Each geometry option is segmented and presented clearly against the user's facial features, allowing precise alignment and focus on specific target areas while maintaining the ability to choose from multiple styles.

AI summary
A method includes: accessing a canvas image including; a target left eyebrow geometry arranged on a left side of a facial centerline and including a first set of curvilinear segments; and a target right eyebrow geometry arranged on a right side of the facial centerline opposite the left target left eyebrow geometry and including a second set of curvilinear segments. The method also includes, during an annotation period: via a projection system, projecting the canvas image onto a user's face; centering the facial centerline of the canvas image on the user's face; locating the first set of curvilinear segments of the target left eyebrow geometry, projected onto the user's face, relative to features of the left eyebrow of the user; and mirroring the second set of curvilinear segments of the target right eyebrow geometry, projected onto the user's face, across the vertical face centerline.
