Printing Apparatus Height Adjustment for Irregular Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile printing apparatuses face challenges in printing on objects with irregular shapes and sizes, such as T-shirts, due to raised portions like pockets or buttons, which can cause wrinkling and printing failures as the printing head interferes with these features.
Innovation Solution
A printing apparatus featuring a first support with adjustable height and a second support with a higher flat surface that can be positioned to accommodate raised portions, allowing the printing head to maintain a consistent distance from the object, thereby preventing printing defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single flat support surface is used, then the structure is simple, but printing failures occur on objects with raised portions
Solution Approach 1:
The support surface is divided into multiple height levels by providing a first support with a first flat surface and a second support with a second flat surface positioned at a different height. This segmentation allows different portions of the printing object to be supported at appropriate heights, preventing printing failures on objects with raised portions while maintaining overall structural simplicity.
2Adaptability or versatility
If the support surface height is fixed, then the device is simple to operate, but it cannot accommodate objects with varying shapes and raised portions
Solution Approach 1:
The support system provides different height levels at different locations by positioning the second support at a second height different from the first height. This local variation in support height allows the system to adapt to objects with varying shapes and raised portions without requiring complex overall adjustments, maintaining ease of operation while improving adaptability.

AI summary
A printing apparatus includes a first support and a second support to support a printing object. The first support has a first flat surface to support the printing object, and includes a plurality of positioning portions at a plurality of positions of the first flat surface. The second support has a second flat surface to support the printing object, and includes a positioned portion to be positioned on any one of the plurality of positioning portions of the first support, with the second flat surface being higher than the first flat surface.
