Fabric Printing Apparatus Positioning via Retainer Surface Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses for fabric struggle with easy positioning of fabric as a recording medium, often requiring manual alignment and additional tools like scanners for precise placement, which can be cumbersome and inefficient.
Innovation Solution
A printing apparatus with a retainer unit, ink ejecting unit, and print controlling system that allows for easy positioning of fabric by printing positioning information on the retainer surface, enabling users to align the fabric accurately without external image input devices, using a system that includes a retainer surface with a sheet member and a platen, and a positioning information storing system to guide fabric placement based on fabric type and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment and external tools like scanners are used for fabric positioning, then positioning accuracy can be achieved, but device complexity and operation difficulty increase
Solution Approach 1:
A positioning sheet is introduced as an intermediary element between the fabric and the printing apparatus. The positioning sheet contains printed positioning information (grid lines, coordinate markers) that mediate the alignment process, allowing users to position fabric accurately without complex scanning or measurement devices. The positioning sheet serves as a simple visual guide that bridges the gap between the fabric and the printing coordinates.
Solution Approach 2:
Instead of using complex image input devices like scanners to capture fabric positioning information, the system creates a simplified copy or representation of positioning data in the form of printed markers and grid lines on the positioning sheet. This copied positioning information is sufficient for alignment purposes and eliminates the need for expensive and complex scanning equipment.
2Ease of operation
If manual alignment procedures are used for fabric positioning, then positioning can be achieved, but operation time and efficiency decrease
Solution Approach 1:
The positioning information (grid lines, coordinate markers, alignment patterns) is pre-printed on the positioning sheet before the actual printing process. This preliminary preparation of positioning data eliminates the need for time-consuming manual measurement and alignment calculations during operation. Users simply need to visually align the fabric with the pre-printed markers, significantly reducing positioning time.
3Area of stationary object
If fabric size is greater than the supporting surface, then complete fabric coverage is possible, but positioning and alignment become more difficult
Solution Approach 1:
The positioning system divides the large fabric into manageable sections using grid lines and coordinate markers printed on the positioning sheet. Instead of requiring alignment of the entire large fabric at once, the grid system allows users to align the fabric section by section or quadrant by quadrant, making the alignment process much easier and more systematic even when the fabric exceeds the supporting surface area.
