Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transfer roller is used for printing, then printing can be performed without exposure and development, but misalignment occurs due to significant unevenness in the rotation speed of the roll
Solution Approach 1:
The invention replaces the conventional rotating transfer roller with a static arc table that swings between contact and non-contact states. This dynamic positioning eliminates the rotation speed unevenness problem while maintaining the transfer function, thereby resolving the contradiction between printing simplicity and alignment accuracy.
Solution Approach 2:
The invention substitutes the rotational mechanical system (transfer roller) with a swinging arc table system. This replacement eliminates the source of misalignment (rotation speed unevenness) while preserving the essential printing function, thus improving alignment accuracy without complicating the manufacturing process.
2Productivity
If a rotating transfer roller is used, then ink transfer can be achieved, but misalignment increases due to variations in rotation speed
Solution Approach 1:
The arc table swings dynamically between contact and non-contact positions, enabling ink transfer without requiring continuous rotation. This dynamic operation eliminates position accuracy degradation caused by rotation speed variations while maintaining printing efficiency.
Solution Approach 2:
The arc table performs periodic swinging motion to complete the ink transfer cycle (contact for transfer, non-contact for positioning). This periodic action replaces continuous rotation, eliminating the accumulation of misalignment errors while maintaining productive printing operation.

AI summary
A printing device is used, which includes a substrate table having a flat surface and holding a target, an arc table having a curved portion, and a controller and configured such that the controller swings the arc table in a state in which the curved portion holding ink faces the substrate table and causes the arc table to contact the target to transfer the ink onto the target. Moreover, a printing method is used, which includes an application step of applying ink to an arc table, a receiving step of receiving part of the ink by a printing plate on a printing plate table by contact between the ink on the arc table and the printing plate, and a transfer step of transferring the ink remaining on the arc table onto a target on a substrate table.
