Print Media Stacker Ramp Curving for Inline Image Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large format printing systems lack efficient and integrated solutions for stacking printed media, often requiring manual handling or separate stackers, which can lead to deformation and inefficiencies in media handling and viewing of printed images during the printing process.
Innovation Solution
A printer-integrated stacker system with a ramp and top guide mechanism that curves and supports printed media at an angle, allowing for inline stacking while preventing buckling and enabling the printed image to face the operator, utilizing a retractable bridge and pinch wheels for continuous media advancement and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual stacking is used, then operators can handle media, but it requires separate handling and increases loss of time
Solution Approach 1:
The patent combines the printing function and stacking function into a single integrated system. The printer includes an integrated stacker that automatically receives and stacks printed media without requiring separate manual handling or separate dedicated stackers, thereby improving productivity and eliminating time loss associated with media transfer between devices.
2Extent of automation
If separate dedicated stackers are used, then automatic stacking is achieved, but it increases device complexity and occupies more space
Solution Approach 1:
The patent integrates the stacking mechanism directly into the printer structure, combining two previously separate functions (printing and stacking) into one unified device. This reduces device complexity and eliminates the need for separate dedicated stackers while maintaining automatic stacking capability.
Solution Approach 2:
The printer is designed to perform multiple functions: it can print media and simultaneously stack the printed media using an integrated stacker. This multi-functional design eliminates the need for separate specialized devices, reducing overall system complexity while maintaining automation.
3Ease of manufacture
If media is stacked without support, then stacking is simple, but media deformation occurs during stacking
Solution Approach 1:
The patent implements a support surface within the integrated stacker that provides localized support to the media during the stacking process. This ensures that large format media maintains its flatness and integrity as it is being stacked, preventing deformation while keeping the stacking mechanism relatively simple.
4Productivity
If stacked media faces away from operator, then stacking is straightforward, but operators cannot view printed images during printing
Solution Approach 1:
The patent employs a dynamic media handling system that curves and orients media as it moves through the integrated stacker. The support surface and guide structures dynamically adjust media orientation during the stacking process, allowing printed images to face the operator while maintaining continuous printing operations without interruption.
