Fixation Unit Removal via Stacker Opening in Image Formation Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image formation apparatuses require opening the apparatus cover to remove the fixation unit, which is inefficient and complicates operations such as replacing the fixation unit or addressing paper jams.
Innovation Solution
The image formation apparatus is designed with a stacker on the periphery of the apparatus housing that includes an opening, allowing the fixation unit to be detached and removed without opening the apparatus cover, by exposing part of the fixation unit through this opening, enabling its removal while the cover remains closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus cover is opened to remove the fixation unit, then the fixation unit can be accessed and removed, but the operation efficiency decreases and the apparatus structure becomes more complex
Solution Approach 1:
The apparatus cover is segmented with a specific opening portion that allows selective access to the fixation unit. This segmentation enables the fixation unit to be removed through the opening without requiring the entire cover to be opened, thus improving operation efficiency while maintaining structural integrity.
Solution Approach 2:
The fixation unit is extracted from the fully enclosed apparatus housing and repositioned such that it can be accessed through the opening in the apparatus cover. This extraction allows the fixation unit to be removed without opening the entire cover, resolving the contradiction between ease of operation and device complexity.
2Loss of time
If the fixation unit is exposed through the opening of the stacker, then the fixation unit can be removed without opening the apparatus cover, but the apparatus housing structure becomes more complex
Solution Approach 1:
The apparatus cover is divided into a main body and an opening portion, allowing selective access to the fixation unit. This segmentation enables quick removal of the fixation unit through the opening without requiring the entire cover to be opened, reducing time loss while maintaining a relatively simple housing structure.
Solution Approach 2:
The opening in the apparatus cover serves multiple functions: it allows the fixation unit to be accessed and removed, provides ventilation, and maintains the aesthetic appearance of the apparatus. This multi-functionality reduces the need for additional structural elements, thereby minimizing the increase in device complexity.
3Productivity
If the apparatus cover remains closed during fixation unit removal, then operational efficiency improves, but access to the fixation unit becomes more difficult
Solution Approach 1:
The fixation unit is extracted from the fully enclosed apparatus housing and repositioned such that it can be accessed through the opening in the apparatus cover. This extraction allows users to remove the fixation unit without opening the entire cover, improving productivity while maintaining ease of operation through the accessible opening.
Solution Approach 2:
The opening in the apparatus cover acts as an intermediary access point between the user and the fixation unit. This intermediary structure allows the fixation unit to be accessed and removed without requiring the entire cover to be opened, thus improving both productivity and ease of operation.

AI summary
An image formation apparatus according to an embodiment may include: an apparatus housing including a stacker formed on a periphery of the apparatus housing, wherein the stacker includes an opening; an image formation part provided in the apparatus housing and configured to form an image on a medium; and a fixation unit detachably attached in the apparatus housing and configured to fix the image formed by the image formation part on the medium, wherein in a state where the fixation unit is attached in the apparatus housing, a part of the fixation unit is exposed through the opening of the stacker to constitute a part of the stacker such that the opening of the stacker allows the fixation unit to be taken out from the apparatus housing therethrough.
