Printing Device Frame Member for Accurate Nail Tip Layout Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing devices face challenges in accurately recognizing and printing on three-dimensional objects placed arbitrarily on a tray, leading to difficulties in achieving high accuracy in printing.
Innovation Solution
A printing device equipped with a frame member that surrounds the recording medium, an acquisition part to capture and process image data to determine the layout, and a print control part to control the printing based on the acquired information, ensuring accurate placement and printing even when the object is positioned arbitrarily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user places the three-dimensional object at an arbitrary position on the tray, then the ease of operation is improved, but the manufacturing precision deteriorates because the printing device cannot recognize the layout
Solution Approach 1:
A frame member is introduced as an intermediary element between the tray and the three-dimensional object. The frame member surrounds the object and provides reference information that enables the imaging part to accurately determine the object's layout position, thereby maintaining printing precision even when objects are placed arbitrarily on the tray.
Solution Approach 2:
The imaging part captures an image of the frame member and the three-dimensional object to create a digital representation. This copied visual information is then processed to extract layout data, allowing the system to recognize and adapt to arbitrary object placements without physical repositioning requirements.
2Measurement precision
If a frame member is added to surround the recording medium, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The frame member serves multiple functions simultaneously: it provides mechanical support for the three-dimensional object, defines the printable area boundaries, and acts as a visual reference for the imaging part to detect layout information. This multi-functionality reduces the need for separate components for each purpose.
Solution Approach 2:
The frame member is designed with a color that differs from both the tray and the three-dimensional object. This color contrast enables the imaging part to easily distinguish and detect the frame member's position and shape, improving layout recognition accuracy without requiring complex detection algorithms or additional markers.
