Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Different adsorbents in a disk device deteriorate in performance when handled under the same conditions, leading to potential degradation and reduced efficiency.
Innovation Solution
The disk device incorporates a first and second filter unit with separate accommodation spaces for different adsorbents, such as silica gel and activated carbon, to prevent cross-influence and maintain optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple different adsorbents are disposed in one location and handled under the same condition, then the device structure is simplified, but at least one of the adsorbents deteriorates in performance
Solution Approach 1:
The patent divides the adsorbent arrangement into separate locations (first location and second location) with different handling conditions. The first adsorbent is placed in a first location with first handling conditions, while the second adsorbent is placed in a second location with second handling conditions. This segmentation prevents the different adsorbents from deteriorating each other's performance while maintaining a relatively simple overall structure.
2Reliability
If different adsorbents are placed in separate locations with different handling conditions, then adsorbent performance is maintained, but the device structure becomes more complex
Solution Approach 1:
The patent implements segmentation by creating distinct first and second locations for different adsorbents, each with its own handling conditions. This is achieved through separate filter units (first filter unit and second filter unit) that can be independently installed and maintained, avoiding the need for complex integrated systems while preserving adsorbent performance.
Solution Approach 2:
The patent designs the housing to accommodate multiple filter units with different adsorbents, making the housing structure universal enough to support various adsorbent types and handling conditions. The base and cover structure provides a common framework that can accommodate different filter unit configurations without requiring entirely separate systems for each adsorbent type.
3Object-affected harmful factors
If multiple adsorbents are used to protect against different contaminants, then protection coverage is improved, but cross-interference between adsorbents occurs
Solution Approach 1:
The patent segments the adsorbent system into separate first and second filter units, each containing a specific adsorbent for targeted contaminant protection. The first adsorbent is positioned to handle specific contaminants under first handling conditions, while the second adsorbent handles different contaminants under second handling conditions. This segmentation prevents cross-influence between adsorbents while maintaining comprehensive protection coverage.
Solution Approach 2:
The patent introduces separate filter units as intermediary structures between the external environment and the adsorbents. Each filter unit acts as an independent intermediary that protects its specific adsorbent from interfering substances while allowing targeted contaminant removal. The filter units serve as mediators that isolate different adsorbents from each other's harmful influences.

AI summary
According to one embodiment, a disk device includes a magnetic disk, a housing, a first filter unit, and a second filter unit. The housing is provided with an internal space and is provided with a first through hole. The first filter unit includes a first case with a first accommodation space which is in communication with the first through hole, a first adsorbent in the first accommodation space, and a first filter. The first accommodation space is in communication with the internal space through the first filter. The second filter unit includes a second case with a second accommodation space which is separated from the first accommodation space, a second adsorbent in the second accommodation space, and a second filter. The second accommodation space is in communication with the internal space through the second filter.
