Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring nail size lack precision, leading to suboptimal choices of artificial nails and improper fits, due to user error and time-consuming manual processes.
Innovation Solution
A computer-implemented method using machine vision and machine learning to generate a 3D digital nail model from image data, allowing for accurate determination of nail measurements by segmenting the nail shape and incorporating curvature, with a mobile app that guides users in capturing images from multiple angles and distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used, then users can measure their nails, but measurement precision is low due to user error
Solution Approach 1:
The patent replaces manual mechanical measurement with an automated image processing system. The system captures images of the user's nails using a camera and automatically processes these images through computer vision algorithms to determine nail dimensions. This substitution eliminates human error in reading measurements and calculating sizes, thereby improving both measurement precision and reliability.
Solution Approach 2:
The patent creates a digital copy of the nail by capturing an image and generating a 3D digital model from multiple 2D images. This digital replica allows for precise measurement without physical contact, eliminating the errors associated with manual tape measurement while preserving all necessary dimensional information for accurate sizing.
2Measurement precision
If sizing kits are sent to customers, then nail measurement can be performed, but loss of time occurs due to shipping and waiting
Solution Approach 1:
The patent enables users to perform nail measurement themselves using their own mobile device camera. The system provides guided instructions for capturing nail images and automatically processes them to generate size recommendations. This self-service approach eliminates the need to wait for physical sizing kits to be shipped and returned, reducing time loss while maintaining measurement precision through automated image analysis.
Solution Approach 2:
The patent performs all measurement processing and analysis actions preliminarily within the mobile application. The system captures images, generates 3D models, calculates dimensions, and provides sizing recommendations all in one immediate process. This preliminary completion of the measurement workflow eliminates the need for subsequent shipping and physical kit handling, significantly reducing time loss.
3Adaptability or versatility
If multiple sizes are included in nail sets, then fit options increase, but loss of substance occurs due to unnecessary waste
Solution Approach 1:
The patent provides precise feedback on the user's actual nail dimensions by analyzing images and generating accurate measurements. This feedback allows users to select exactly the size they need rather than guessing from multiple options. By providing this precise measurement feedback, the system enables users to purchase only the specific size required, eliminating the need for manufacturers to include multiple sizes in each set and thereby reducing waste from unsold or returned nails.
