Solid Object Printing System With Rotatable Recording Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid object printing systems face inefficiencies in producing multiple objects, requiring complex rotation control and the use of shape-specific printing jigs, leading to increased costs and time.
Innovation Solution
A system comprising a print table, detection unit, print data generation unit, and control unit that detects the position and orientation of solid objects, generates print data, and performs printing without rotation control, enabling high-definition printing without a fixing jig.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single solid object is rotatable on the solid object support, then printing can be performed on the solid object, but the production efficiency when performing printing on a plurality of solid objects is low
Solution Approach 1:
Instead of rotating the solid object to achieve printing on multiple surfaces, the patent inverts the approach by making the recording head rotatable. The recording head rotates around the solid object while maintaining a fixed solid object support, thereby printing images on multiple surfaces without requiring complex rotation control of the solid object itself.
Solution Approach 2:
The solid object support is designed to universally support multiple solid objects simultaneously without requiring individual rotation control for each object. The support structure can hold several objects in fixed positions while the rotatable recording head services all objects, improving production efficiency for batch processing.
2Manufacturing precision
If rotation control is implemented to improve printing quality, then printing quality improves, but complicated and precise control technology is required, causing cost to be increased
Solution Approach 1:
The patent swaps which component requires precise rotation control - instead of controlling solid object rotation, the recording head is made rotatable with precise control. This inversion maintains printing quality while simplifying the overall system, as the recording head's rotation can be more easily controlled and synchronized with its printing operations.
3Ease of manufacture
If a printing jig is used to perform printing on solid objects, then printing can be performed, but a printing jig is required for each of solid objects of different shapes, and time and effort are required to fix the solid object to the printing jig, increasing the cost required for printing
Solution Approach 1:
The solid object support is designed as a universal fixture that can accommodate multiple different shaped solid objects simultaneously without requiring shape-specific jigs. Each object is positioned in a predetermined location on the support, eliminating the need for complex fixing procedures and reducing preparation time.
Solution Approach 2:
The patent extracts the rotation function from the solid object support system and relocates it to the recording head. This separation allows the support to remain simple and universal, while the recording head handles the complexity of rotation, eliminating the need for printing jigs and fixing procedures.

AI summary
A solid object printing system includes: a print table for mounting a solid object to be subjected to printing; a detection unit for detecting a position and an orientation of the solid object mounted on the print table; a print data generation unit for generating print data corresponding to the solid object on a basis of a detection result of the position and the orientation of the solid object performed by the detection unit; a print unit for performing printing on the solid object by the print data generated by the print data generation unit; and a control unit for controlling the operations of the detection unit, the print data generation unit, and the print unit.
