Nail Print Apparatus Stabilization via Flexible Placement Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail print apparatuses face challenges in maintaining a consistent height position for printing due to varying finger thickness, nail width, and curvature, leading to inaccurate printing and the need for cumbersome adjustments and sensing mechanisms.
Innovation Solution
A nail print apparatus with a nail placement unit that stabilizes the central area of the nail's protruding portion, allowing for consistent printing regardless of finger shape and size, using a flexible unit that deforms to accommodate different nail curvatures and sizes, and a lifting mechanism to maintain the optimal printing height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a jig or adjustment mechanism is used to fix the finger at the correct height, then printing precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a nail placement unit that extends in the width direction to provide a stable placement surface for the nail tip. This dimensional extension allows the nail to be positioned correctly without requiring complex height adjustment mechanisms in the vertical direction, thereby maintaining printing precision while reducing device complexity
Solution Approach 2:
The nail placement unit is designed to automatically stabilize the nail at the correct position through its extended width, allowing the system to self-position the nail without requiring manual adjustment by the user. This eliminates the need for complex adjustment mechanisms while maintaining printing precision
2Manufacturing precision
If a sensing mechanism is added to detect nail height information, then printing precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the proposed sensing mechanism with a mechanical nail placement unit that physically stabilizes the nail at the correct height through its extended width structure. This mechanical approach eliminates the need for electronic sensors and feedback systems, reducing device complexity and cost while maintaining printing precision
Solution Approach 2:
The nail placement unit acts as an intermediary mechanical structure between the user's finger and the print head. It provides a stable reference surface that passively maintains the correct nail height without requiring active sensing or feedback control systems
3Adaptability or versatility
If the camera distance is adjusted to accommodate different nail sizes, then adaptability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent stabilizes the nail in the width direction through the extended nail placement unit, which provides a consistent reference position. This allows the camera to maintain a fixed distance while still accommodating different nail sizes, thereby maintaining both adaptability and measurement precision

AI summary
A nail print apparatus, including: a nail placement unit on which a central area in a protruding portion of a nail of a finger or a nail of a toe is placed, the protruding portion of the nail is an area that protrudes from a distal portion of the finger or the toe and the central area includes a center of the protruding portion in a width direction of the nail; and a print head which performs printing on the nail that the central area is placed on the nail placement unit.
