Detachable Exhaust Fan Unit for Printer Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image forming apparatuses, such as printers, require time and effort to replace the dust-collecting filter due to their hierarchical configuration, which necessitates the removal and reattachment of multiple components in a specific order.
Innovation Solution
The image forming apparatus is designed with an exhaust fan unit that integrates the exterior cover, exhaust fan, and filter, allowing for easy detachment and attachment from the apparatus body, thereby simplifying the filter replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is placed inside the exhaust fan in a hierarchical configuration, then the exhaust fan is protected from contaminants, but the replacement work takes time and effort
Solution Approach 1:
The exhaust fan unit is segmented into a detachable assembly that includes the exterior cover, exhaust fan, and filter as integrated components. This segmentation allows the entire unit to be removed and reattached as a single module, enabling quick filter replacement without the need to disassemble the hierarchical structure of separate components.
Solution Approach 2:
The exterior cover, exhaust fan, and filter are merged into a single integrally formed exhaust fan unit. This combining of components that were previously separate and hierarchically arranged allows them to be handled as one unit, significantly reducing the time and effort required for filter replacement while maintaining the protective function.
2Stability of the object's composition
If the exterior cover, exhaust fan, and filter are arranged in hierarchical order, then the structure is stable, but the replacement process requires multiple removal and attachment steps
Solution Approach 1:
The exhaust fan unit is designed with detachable and reattachable characteristics, transitioning from a fixed hierarchical structure to a dynamic modular structure. This allows the unit to be easily removed and reattached while maintaining structural stability during operation, significantly improving the ease of filter replacement.

AI summary
An image forming apparatus includes: a recording portion configured to eject ink onto a sheet to form an image; a conveying portion facing the recording portion, and configured to convey the sheet; and an exhaust fan unit attached to an apparatus body, the exhaust fan unit being detachable from the apparatus body, in which the exhaust fan unit includes: an exterior cover having an exhaust port through which air passes to the outside; an exhaust fan configured to generate an air flow toward the outside; a filter; and a case configured to integrally hold the exterior cover, the exhaust fan, and the filter so that the exhaust fan is disposed between the exterior cover and the filter.
