Heating Unit Integrates Image Fixing and Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices require additional space for a separate image removing unit, which is not efficient in terms of space utilization and integration with the image forming device.
Innovation Solution
The image processing device integrates the image forming and removing functions using a heating unit that fixes images at a predetermined temperature and then removes them by heating the toner to a higher temperature, eliminating the need for a separate image removing unit by utilizing common carrying paths for both fixing and removing images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate image removing unit is disposed outside the image forming device, then the image removing function can be performed, but the device occupies more space and requires additional disposal space
Solution Approach 1:
The patent merges the image removing unit with the image forming device by integrating the heating unit into the existing fixing device structure. The same heating unit that fixes images at predetermined temperature is utilized to remove images by heating to higher temperature, thereby eliminating the need for separate disposal space while maintaining the image removing function.
Solution Approach 2:
The heating unit is designed to perform multiple functions: it serves as the fixing heating unit during normal printing operations and as the image removing heating unit when removal is needed. This multi-functionality allows the same hardware component to achieve both image fixing and image removal, reducing overall device space requirements.
2Adaptability or versatility
If the heating unit heats the sheet to a temperature higher than the fixing temperature, then the image can be removed, but the energy consumption increases
Solution Approach 1:
The system utilizes the existing heating unit and its control mechanisms to serve the dual purpose of fixing and removing images. By leveraging the already-present heating infrastructure and its control systems, the patent avoids the need for separate heating systems, thereby managing energy consumption more efficiently while achieving image removal capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integration allows for space-saving solutions by using the same heating unit for both fixing and removing images, eliminating the need for additional space for a separate image removing unit and optimizing the device's hardware configuration.
Implementation Method 1
The heating unit heats the sheet, on which an image is formed by the image forming unit, at a predetermined temperature, to thereby fix the image on the sheet
Implementation Method 2
The heating unit heats the sheet, which is supplied from the supplying unit and to which the image is fixed, at a temperature higher than the predetermined temperature to thereby remove the image

AI summary
An image processing device has a first supplying portion that supplies a sheet on which an image is fixed previously. A removing portion removes the image formed on the sheet. A first storing portion stores the sheet from which the image is removed by the removing portion. The first supplying portion and the first storing portion are integrally formed as a unit capable of detaching from the main body of the image processing device.
