Detachable Duct and Filter for Ink Mist Contamination in Recording Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In recording devices with air current generators, foreign substances like ink mist accumulate not only in filters but also inside ducts, leading to contamination of the recording medium.
Innovation Solution
The recording device includes a detachable duct and filter configuration, allowing for easy cleaning or replacement by detaching the duct or filter from the base body, preventing foreign substances from adhering to the recording medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed duct and filter configuration is used in the recording device, then the device structure is simple and stable, but foreign substances accumulate inside the duct and cause contamination of the recording medium
Solution Approach 1:
The duct is divided into a fixed portion and a detachable portion that can be separated from each other. The detachable portion can be removed independently to clean accumulated foreign substances, while the fixed portion remains attached to the base body. This segmentation allows maintenance without disassembling the entire device, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The filter is designed to be detachable from the base body, allowing it to be easily removed for cleaning or replacement. By extracting the filter as a separate removable component, the system enables efficient maintenance to prevent contamination while keeping the overall device structure relatively simple.
2Ease of operation
If the duct is made detachable for easy cleaning, then foreign substances can be removed effectively, but the device structure becomes more complex
Solution Approach 1:
The duct is segmented into fixed and detachable portions connected through a detachable connection structure. This segmentation enables easy removal of the detachable portion for cleaning while maintaining a relatively simple overall structure through standardized connection interfaces.
Solution Approach 2:
The duct transitions from a completely fixed structure to a dynamic structure where the detachable portion can be easily attached and detached. This dynamic design allows flexible maintenance operations while using simple connection mechanisms that do not significantly increase device complexity.
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 configuration effectively prevents the recording medium from becoming dirty by allowing for the removal and replacement of accumulated foreign substances within the duct and filter, improving operational efficiency and reducing contamination risks.
Implementation Method 1
a duct (28) configuring an air current flow path formed from the opening (31) to the air current generator (26)
Implementation Method 2
a filter (27) disposed between the opening (31) and the air current generator (26)
