Vertical Stacking of Drying and Stitching Units in Medium Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medium processing apparatuses, especially those integrated with inkjet printers, the high friction from ink ejection surfaces leads to deterioration of medium integrity in loading trays, necessitating a drying mechanism that increases the apparatus's size and horizontal footprint.
Innovation Solution
The apparatus includes a receiving portion, a first processing unit for drying, and a second processing unit for additional operations like end stitching, with the first processing unit located vertically below the second and overlapping when viewed vertically, allowing for miniaturization by reducing horizontal dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drying mechanism is provided inside the medium processing apparatus to accelerate drying of the medium, then the integrity of the medium is maintained, but the size of the apparatus increases
Solution Approach 1:
The patent applies vertical stacking of processing units, arranging the drying mechanism (first processing unit) and other processing units (second processing unit) in different vertical levels. This three-dimensional arrangement allows the drying function to be integrated without increasing the horizontal footprint, effectively resolving the contradiction between maintaining medium integrity and minimizing apparatus size.
2Productivity
If the medium processing apparatus is integrated with the ink jet printer, then the productivity is improved, but the friction from ink ejection surface causes deterioration of medium integrity
Solution Approach 1:
The patent implements a drying mechanism that performs preliminary drying action on the medium immediately after ink ejection, before the medium is transported to the loading tray. This preliminary drying prevents the high friction problem from occurring, thereby maintaining medium integrity while preserving the integrated productivity benefits.
3Device complexity
If the first processing unit and second processing unit are arranged vertically with overlapping portions, then the device complexity is reduced, but the manufacturing precision becomes more difficult to control
Solution Approach 1:
The patent divides the processing apparatus into separate functional modules (first processing unit for drying, second processing unit for other operations) that are vertically stacked. Each module can be manufactured and assembled independently, which simplifies the overall manufacturing process while maintaining precise alignment through modular connection interfaces.

AI summary
A first unit includes a receiving portion that receives a medium to be processed, a drying unit that processes the medium received from the receiving portion, and an end stitching unit that processes the medium received from the receiving portion or the medium processed by the drying unit. The processing performed by the drying unit is processing of drying the medium, the drying unit is located vertically below the end stitching unit, and the drying unit and the end stitching unit have a portion overlapping when viewed in a vertical direction.
