Integrated Cleaning Mechanism for Image Capturing Unit in Medium Stacking Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medium stacking devices impose a large operation burden on users as they require separate cleaning operations for the image capturing unit, which is not integrated with the movement of the device, leading to inefficiencies and increased user effort.
Innovation Solution
A medium stacking device with a cleaning unit that cleans the image capturing unit in conjunction with the movement of the device's moving unit, specifically the stacking unit, during its pull-out and insertion operations, thereby reducing the user's operational burden and improving cleaning frequency and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cleaning operation is required for the image capturing unit, then the cleaning function can be performed, but the operation burden on the user increases
Solution Approach 1:
The patent combines the cleaning unit with the moving unit (stacking unit) so that both functions are integrated into a single operational mechanism. The cleaning unit is positioned to clean the image capturing unit when the stacking unit is pulled out or inserted, eliminating the need for separate cleaning operations.
Solution Approach 2:
The moving unit (stacking unit) is designed to serve multiple functions: it both moves the stacking tray for medium replenishment and simultaneously performs cleaning of the image capturing unit. This multi-functionality reduces the number of separate operations the user must perform.
2Device complexity
If the cleaning unit operates independently from the moving unit, then the cleaning mechanism can be simplified, but the cleaning frequency decreases
Solution Approach 1:
The cleaning action is performed automatically during the necessary movement operations (pulling out or inserting the stacking unit), so cleaning occurs proactively before contamination affects image quality, rather than requiring separate scheduled cleaning intervals.
Solution Approach 2:
The cleaning function is continuously integrated with the moving unit's operation, ensuring that cleaning occurs whenever the stacking unit is moved. This continuous integration ensures frequent cleaning without requiring additional dedicated cleaning cycles.
3Ease of operation
If the cleaning unit is integrated with the moving unit, then the operation burden is reduced, but the device complexity increases
Solution Approach 1:
The cleaning unit is merged with the moving unit by positioning the cleaning unit on the moving unit and configuring it to clean the image capturing unit during the movement operation. This integration shares mechanical structures and control systems, reducing overall device complexity despite the added functionality.
