Printing Apparatus Double-Face Printing and Cutting Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses equipped with cutter assemblies are not capable of efficiently handling double-face printing operations, where images are printed on both sides of the printing medium, and subsequent cutting processes to divide the medium into usable parts.
Innovation Solution
A printing apparatus with a multifunctional design that includes a cutter assembly and a controller capable of performing double-face printing by switching the printing sheet between conveyer paths to print on both sides and then cut it into separate sheets, optimizing the use of RAM and ensuring accurate image placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional printing apparatus with cutter assembly is used, then single-face printing and cutting can be performed, but double-face printing operation cannot be performed
Solution Approach 1:
The printing apparatus is designed to perform multiple functions including printing on both sides of the printing medium and cutting operations. The system integrates a printing unit, a cutter assembly, and a controller that coordinates both functions, enabling the device to handle both printing and cutting tasks within a single apparatus.
Solution Approach 2:
The system divides the printing process into separate operations for each side of the printing medium. The controller manages distinct printing operations for the front and back sides, and separately controls the cutter assembly to cut the printed medium, creating multiple processed materials from a single input sheet.
2Productivity
If double-face printing is performed on a printing sheet, then both sides can be printed, but the sheet cannot be efficiently cut into usable parts
Solution Approach 1:
The system merges the printing and cutting operations into a single integrated workflow. The printing unit prints on both sides of the medium, and the cutter assembly immediately follows to cut the printed sheet into desired shapes or sizes, eliminating the need for separate handling steps.
Solution Approach 2:
The system performs preliminary printing on both sides of the printing medium before the cutting operation. The controller coordinates the printing unit to complete both front and back side printing, then activates the cutter assembly to cut the fully printed sheet, ensuring all printing is done before any cutting occurs.
3Adaptability or versatility
If a cutter assembly is added to enable cutting, then cutting function is provided, but the apparatus cannot handle double-face printing operations
Solution Approach 1:
The apparatus is designed as a multi-functional system that combines both printing and cutting capabilities. The controller integrates the operation of the printing unit and the cutter assembly, allowing the device to perform printing on both sides of the medium and subsequently cut it, providing universal functionality for both operations.
Solution Approach 2:
The system dynamically switches between printing and cutting operations based on the processing stage. The controller manages the transition from printing mode to cutting mode, coordinating the printing unit to complete both sides of the medium before activating the cutter assembly, thereby adapting the system's function according to the current operational phase.
4Productivity
If conventional printing and cutting are performed separately, then each function works independently, but double-face printing with subsequent cutting cannot be achieved
Solution Approach 1:
The system merges previously separate printing and cutting operations into an integrated process. The controller combines the printing unit and cutter assembly into a coordinated system that performs double-face printing followed by cutting in a single continuous workflow, eliminating the need for separate independent operations.
Solution Approach 2:
The controller monitors the completion of printing on both sides of the medium and uses this information to trigger the cutting operation. The system tracks the printing process and provides feedback to determine when the printing is complete, then automatically activates the cutter assembly to perform the cutting operation.

AI summary
A printing apparatus, having a conveyer, a first conveyer path, a printer, a cutter assembly, and a controller, is provided. The cutter assembly cuts the printing medium into a first part located frontward and a second part located rearward in a first conveying direction. The controller controls the printer to print an image in the second part on one side of the printing medium, controls the conveyer to move the printing medium from the first conveyer path to a second conveyer path through a first switchback action and inverts the printing medium by conveying in a second conveying direction, controls the printer to print an image in the second part on the other side of the printing medium, and controls the cutter assembly to cut the printing medium into a first printing medium having the first part and a second printing medium having the second part.
