Nail Print Apparatus Design Element Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail print apparatuses fail to accurately print design images within the nail region, leading to deformation and uneven spacing, resulting in an impression different from the user's selection due to varying nail shapes and sizes.
Innovation Solution
A nail print apparatus that includes an imaging section, a nail region information detecting section, a print design image generating section, and a printing section, which generates and adjusts the design image based on a standard nail model to ensure the design elements are proportionally sized and positioned within the user's nail region, preventing overflow and ensuring the desired impression is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the scale of the entire image data is changed to fit the nail region, then the design image can be printed within the nail region, but each pattern may be deformed and the space between pattern portion and boundary becomes unnatural
Solution Approach 1:
The patent divides the image processing into two independent stages: first scaling the background image data to fit the nail region, then separately adjusting the position and size of pattern elements. This segmentation allows the background to be properly scaled while preserving the original shape and spacing of individual patterns, preventing deformation while maintaining printing accuracy within the nail region.
2Manufacturing precision
If the image data is reduced to fit smaller nail regions, then printing within the nail region is achieved, but portions of patterns may be printed outside the nail region or the image is reduced too much
Solution Approach 1:
The patent separates background image scaling from pattern element positioning. The background image is scaled to fit the nail region boundaries, while pattern elements are independently positioned and sized based on the scaled background, ensuring patterns remain within the nail region without being excessively reduced.
Solution Approach 2:
The system uses the detected nail region boundaries as feedback to dynamically adjust the scaling of background images and the positioning of patterns. By continuously referencing the actual nail region dimensions and boundaries, the system ensures patterns are correctly positioned within the nail region regardless of size variations, maintaining measurement precision.
3Adaptability or versatility
If the scale of the entire image data is changed, then the design image fits the nail region size, but the impression of the design image selected by the user is different from the image actually printed
Solution Approach 1:
The patent divides the design image into background image data and pattern element data, processing them differently. The background is scaled to adapt to various nail region sizes, while pattern elements maintain their original characteristics and are independently positioned. This segmentation preserves the user's design impression while providing adaptability to different nail sizes.
Solution Approach 2:
The patent applies different processing qualities to different parts of the design image. The background image undergoes scaling to adapt to local nail region variations, while pattern elements maintain their original quality and characteristics. This local quality approach ensures the design impression is preserved in critical pattern areas while adapting the overall layout to fit different nail sizes.

AI summary
A nail print apparatus which prints on a nail and a printing control method of the nail print apparatus. In one implementation of the present invention, the nail print apparatus includes a imaging section; a nail region information detecting section which detects an outline and an area of the nail region; a print design image generating section; an element position judging section which judges whether or not a design element is contained within the nail region; and a printing section. The print design image generating section positions a design element in a position in the nail region which corresponds to a position on a standard nail model an element to a value in proportion with a ratio of the area of the nail region to an area of the standard nail model.
