Solution Overview
Problem
Existing hand-held vacuum cleaners face challenges in maintaining suction performance over time due to filter clogging, which requires increasing the filter area, thus altering the internal structure, and struggles with effective foreign substance filtration without changing the cleaner's structure.
Innovation Solution
The design incorporates a filter mechanism that protrudes and is accommodated through an opening cover, allowing for increased filter area without altering the cleaner's structure, using a filter unit with a bent design to enhance filtration efficiency and accommodate more foreign substances, thereby reducing suction performance deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter area is increased to maintain suction performance, then foreign substance filtering performance is improved, but the internal structure of the cleaner must be changed
Solution Approach 1:
The filter mechanism is designed to be movable rather than fixed. The filter can protrude outward from the cleaner body when the opening cover is separated, and be pressed inward when the opening cover is coupled. This dynamic configuration allows the filter area to be effectively increased without permanently altering the internal structure of the cleaner.
Solution Approach 2:
The filter mechanism utilizes the spatial dimension created by the opening cover separation. By allowing the filter to extend in the direction perpendicular to the cleaner body (when the cover is separated), the design effectively increases filter area without requiring additional internal space within the cleaner's fixed structure.
2Duration of action of moving object
If the filter area is increased to reduce deterioration of suction performance, then cleaning duration is extended, but the structure of the cleaner body must be changed
Solution Approach 1:
The movable filter mechanism allows for increased filter surface area that can accommodate more foreign substances over time, thereby extending the cleaning duration before performance deterioration occurs. This is achieved without modifying the cleaner body structure since the filter moves between protruded and accommodated positions.
Solution Approach 2:
The filter is designed to be in a protruded position during cleaning operations, maximizing its filtering capacity before the opening cover is separated. This preliminary positioning ensures optimal filtering performance throughout the cleaning duration while maintaining the original cleaner structure.
3Reliability
If a larger filter is used to capture more foreign substances, then filtering efficiency is improved, but the cleaner's compact design is compromised
Solution Approach 1:
The filter mechanism utilizes the external space created when the opening cover is separated to accommodate a larger filter surface area. By extending the filter outward in the vertical dimension rather than expanding the cleaner's horizontal volume, the design maintains its compact footprint while achieving improved filtering efficiency.
Solution Approach 2:
The filter dynamically transitions between a compact accommodated state (when the opening cover is coupled) and an extended protruded state (when the opening cover is separated). This allows the cleaner to maintain its compact volume during storage and transport while providing enhanced filtering efficiency during operation.

AI summary
The cleaner includes a main body having an opening, a suction motor accommodated in the main body and configured to generate suction force, an opening cover separably coupled to the main body and configured to cover the opening, and a filter mechanism accommodated in the main body through the opening and configured to filter foreign substances of air discharged by the suction motor. When the opening cover is separated from the main body, at least a portion of the filter mechanism protrudes to the outside of the main body through the opening. While the opening cover is coupled to the main body, at least a portion of the filter mechanism protruding to the outside of the main body is pressed by the opening cover so as to be accommodated in the main body.
