Nail Print Apparatus Automatic Design Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail print apparatuses face challenges in fitting design images perfectly onto nails of varying shapes and sizes, leading to unprinted areas and distortion, requiring manual adjustment and preparation of large design images.
Innovation Solution
A nail print apparatus with an image data processing unit that processes image data to ensure the second design covers the entire nail region, using a print head to print the first design and second design, which are adjusted in size and position to fit the nail accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the design image is merely synthesized with the approximate outline of the nail, then the printing process is simple, but the design image cannot completely fit the nail causing unprinted areas and running off the edge
Solution Approach 1:
The system performs preliminary detection of the nail's actual shape and size using an image acquisition unit before printing. Based on this detected information, the image processing unit automatically adjusts the design image's size, aspect ratio, and position in advance to ensure perfect fitting, eliminating the need for manual user adjustment while preventing unprinted areas and edge running-off.
2Manufacturing precision
If the user manually adjusts the size, aspect ratio and position of the pattern to fit the nail, then the design image fits the nail perfectly, but it requires considerable time and trouble
Solution Approach 1:
The system enables self-service by automatically detecting the nail's characteristics and independently performing the image adjustment process. The image processing unit autonomously calculates and applies the optimal size, aspect ratio, and position based on the detected nail shape, completely eliminating the need for manual user intervention and saving significant preparation time while maintaining perfect fitting precision.
3Area of stationary object
If the second design is reduced and adjusted to the size and shape of the nail, then the background covers the nail, but the picture loses arrangement balance or gets distorted
Solution Approach 1:
The system applies local quality by treating the first design (main picture) and second design (background) differently during the adjustment process. The image processing unit maintains the original aspect ratio and arrangement balance of the first design while independently adjusting the second design's coverage to ensure it extends to the nail edges. This localized differentiation prevents distortion of the main picture while achieving complete background coverage.
4Area of stationary object
If the design image is fitted so as to cover the whole vertical length with the second design, then the background covers the nail, but the first design becomes so large as to run off the edge or becomes distorted
Solution Approach 1:
The system implements dynamics by making the image adjustment parameters variable rather than fixed. The image processing unit dynamically calculates different scaling factors and position offsets for the first and second designs based on the detected nail shape. This allows the background to extend to the edges while the main picture is simultaneously adjusted to fit within the nail boundaries, preventing both running-off and distortion through adaptive, dynamic parameter adjustment.

AI summary
A nail print apparatus, including: a print head which performs printing on a nail region on the basis of image data including a first design and a second design that is a background of the first design; and an image data processing unit which has a second image data processing unit that processes the image data so that the second design covers an entire nail region.
