Solution Overview
Problem
Existing printer systems face challenges in accurately aligning and stacking printed substrates of varying sizes and dimensions, often requiring labor-intensive calibration and prone to noise, which can result in stacks that fail to meet quality specifications.
Innovation Solution
A stacking system utilizing movable stacking members and controllers to position and align substrates precisely, allowing for independent stacking and adjustment of substrates before deposition, including vibration and offset mechanisms to align and distinguish batches, enabling accurate stacking without rigorous calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional stacking methods are used, then the stacking process is simpler, but alignment precision and stack quality deteriorate
Solution Approach 1:
The stacking system is divided into multiple independent stacking members (first stacking member, second stacking member) that can operate independently. Each stacking member handles specific substrates or batches, allowing precise control of alignment for each segment while maintaining overall system functionality.
Solution Approach 2:
The stacking members are designed to be movable between different positions (first position for receiving substrates, second position for depositing onto stacks). This dynamic capability allows the system to adapt to different substrate sizes and dimensions while maintaining high alignment precision through controlled movement and positioning.
2Adaptability or versatility
If substrates of varying sizes are stacked, then versatility is improved, but alignment precision deteriorates
Solution Approach 1:
The stacking members can move between different positions and configurations to accommodate substrates of varying sizes. The system dynamically adjusts the positioning of stacking members to maintain proper alignment regardless of substrate dimensions, enabling versatility without sacrificing precision.
Solution Approach 2:
The system performs preliminary positioning and alignment of substrates on the stacking members before final deposition onto the stack. This preliminary action ensures that substrates of varying sizes are properly aligned and oriented before being added to the final stack, maintaining alignment precision across different substrate dimensions.
3Manufacturing precision
If rigorous calibration is performed, then alignment precision is improved, but time consumption and complexity increase
Solution Approach 1:
The stacking members are designed to self-align and self-position through their movable mechanisms. The system performs its own calibration through the controlled movement and positioning of stacking members during operation, eliminating the need for external rigorous calibration procedures while maintaining high alignment precision.
Solution Approach 2:
The dynamic positioning capability of the stacking members allows the system to automatically adjust and align substrates during the stacking process itself, rather than requiring separate calibration steps. This reduces calibration time while maintaining precision through real-time positional control.
4Manufacturing precision
If substrates are stacked directly without intermediate positioning, then productivity is improved, but alignment precision deteriorates
Solution Approach 1:
The stacking process is segmented into distinct phases: receiving substrates on stacking members, positioning/aligning them, and then depositing onto the final stack. This segmentation allows alignment operations to be performed on smaller groups of substrates simultaneously, maintaining precision while improving overall productivity through parallel processing.
Solution Approach 2:
Substrates are preliminarily positioned and aligned on the stacking members before being deposited onto the final stack. This preliminary positioning action enables multiple substrates to be prepared and aligned in advance, maintaining high alignment precision while improving productivity by reducing the time required during the final stacking operation.

AI summary
An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.
