Nail Drawing Apparatus Height Detection Ink Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawing apparatuses for nail designs face challenges in maintaining drawing quality due to variations in human finger and nail shapes, leading to inconsistent ink placement and potential failure in reaching the nail surface, especially when the nail is not at a uniform height.
Innovation Solution
A drawing apparatus with an insertion portion, nail height detection, and a drawing unit that defines a drawable area based on the nail's height distribution, allowing for precise determination of suitable areas for drawing and adjusting the drawing process accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ink jet drawing head is used to draw on nail, then drawing can be performed, but drawing quality degrades when nail height varies significantly
Solution Approach 1:
The system performs preliminary height detection of the nail surface using an imaging unit before drawing begins. Based on the detected height distribution, the system pre-calculates the appropriate drawing head height and ink ejection timing, ensuring optimal drawing conditions are established before the actual drawing process starts.
Solution Approach 2:
The drawing head height is made dynamically adjustable based on the detected nail height. The system controls the drawing head to move to a position corresponding to the detected nail height, and dynamically adjusts ink ejection timing based on real-time height information, allowing the system to adapt to varying nail heights while maintaining drawing quality.
2Adaptability or versatility
If drawing head is positioned far from nail to accommodate low areas, then all areas can be reached, but ink cannot land correctly at predetermined position
Solution Approach 1:
The system performs preliminary height detection of the nail surface using an imaging unit before drawing begins. Based on the detected height distribution, the system pre-calculates the appropriate drawing head height and ink ejection timing, ensuring optimal drawing conditions are established before the actual drawing process starts.
Solution Approach 2:
The system uses height detection to obtain feedback information about the nail surface topology. This feedback is used to adjust the drawing head position and ink ejection timing in real-time, creating a closed-loop control system that maintains accurate ink placement despite variations in nail height.
3Adaptability or versatility
If pen height is vertically movable within limited range, then some adaptation to nail height is possible, but drawing cannot be performed when nail is outside driving range
Solution Approach 1:
The system performs preliminary height detection of the nail surface using an imaging unit before drawing begins. Based on the detected height distribution, the system pre-calculates the appropriate drawing head height and ink ejection timing, ensuring optimal drawing conditions are established before the actual drawing process starts.
Solution Approach 2:
The drawing head height is made dynamically adjustable based on the detected nail height. The system controls the drawing head to move to a position corresponding to the detected nail height, and dynamically adjusts ink ejection timing based on real-time height information, allowing the system to adapt to varying nail heights while maintaining drawing quality.
