Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing devices struggle to simultaneously form three-dimensional objects and images on a medium with high accuracy, as they require separate devices or complex operations for each task.
Innovation Solution
A printing device with a table attaching portion that can switch between a first table for three-dimensional object shaping and a second table with pass-through holes for medium mounting, along with an ejecting unit for shaping and coloring materials, and a suction portion to adsorb the medium, allowing for precise positioning and simultaneous three-dimensional object shaping and image formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single device is used for both three-dimensional object shaping and image formation, then device versatility is improved, but manufacturing precision for both functions simultaneously deteriorates
Solution Approach 1:
The printing device is segmented into functionally independent modules: a first table for three-dimensional object shaping and a second table with pass-through holes for image formation. This segmentation allows each table to be optimized for its specific function while being integrated into a single versatile device, resolving the contradiction between device versatility and manufacturing precision.
Solution Approach 2:
The device achieves multi-functionality by incorporating both a first table for three-dimensional object shaping and a second table for image formation within one integrated system. The table attaching portion can attach either table, enabling the single device to perform both shaping and image formation operations with high precision for each function.
2Manufacturing precision
If the second table with pass-through holes is used for medium mounting, then image formation precision is improved, but device complexity increases
Solution Approach 1:
The suction portion is merged with the second table structure, forming an integrated assembly where the suction portion decompresses the back surface of the second table to adsorb the medium. This merging reduces the number of separate components and simplifies the overall device structure while maintaining high image formation precision through the pass-through hole design.
3Ease of operation
If the suction portion is arranged integrally with the second table, then ease of operation is improved, but the weight of the table attaching portion increases
Solution Approach 1:
The suction portion is designed to be detachably connected to the second table rather than permanently fixed, allowing dynamic reconfiguration of the device. This detachable connection enables the suction portion to be separated when not needed, reducing the effective weight of the table attaching portion during three-dimensional object shaping operations while maintaining ease of operation when image formation is required.

Function Achieved in This Case
Enables high-accuracy formation of both three-dimensional objects and images on a medium using a single device, with the suction portion maintaining medium position during image formation, thus enhancing overall precision and efficiency.
Implementation Method 1
a suction portion that decompresses a side of the back surface of the second table when the second table is attached to the table attaching portion to adsorb the medium to the mounting surface
