Vacuum Cleaner Filter Cover With Integrated Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices are not user-friendly for maintenance tasks such as filter element and battery replacement, often requiring users to access these components from the dirty side, leading to confusion and complexity in handling.
Innovation Solution
The integration of a filter cover that can pivot from a closed to a removal position, allowing for easy access to the filter element on the clean room side and incorporating a battery holder, simplifies maintenance by providing uniform access and protecting the battery from dirt, while also enabling a compact and mobile design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter element is accessed from the dirty side, then the suction device structure is simple, but the ease of operation deteriorates due to user confusion and difficulty in maintenance
Solution Approach 1:
The patent inverts the traditional access approach by allowing filter element replacement from the clean room side instead of the dirty side. The filter cover pivots to provide access to the filter element from the clean side, eliminating user confusion about where to access maintenance components while maintaining structural simplicity through the pivoting mechanism.
Solution Approach 2:
The filter cover serves multiple functions: it protects the filter element, provides access for maintenance from the clean side when pivoted, and integrates the battery holder. This multi-functionality improves ease of operation without proportionally increasing device complexity.
2Ease of operation
If the battery is integrated into the filter cover, then the ease of operation improves by providing uniform access, but the device complexity increases due to integration requirements
Solution Approach 1:
The battery holder is integrated into the filter cover, combining two maintenance components (filter element and battery) into a single accessible unit. This merging provides uniform access for both maintenance tasks through the same pivoting filter cover mechanism, improving ease of operation while the integration is achieved through straightforward structural design.
3Ease of operation
If the filter cover pivots to removal position, then the ease of operation improves for filter access, but the loss of time increases due to the pivoting action required
Solution Approach 1:
The filter cover is designed as a dynamic component that can pivot between closed and removal positions. This dynamic design allows quick access to the filter element from the clean side when needed, while maintaining protection during operation. The pivoting mechanism enables rapid transition without complex disassembly procedures.

AI summary
The invention relates to a suction device comprising a dirt collection container (14) for material which has been vacuumed up, a suction assembly (24) for subjecting the dirt collection container (14) to the action of a vacuum by means of a suction-removal space (28), at least one filter element (32) which is arranged between the dirt collection container (14) and the suction-removal space (28) in the direction of flow of the air which is removed by suction by the suction assembly (24), at least one rechargeable battery (48, 50) for providing electrical energy for the suction assembly (24), and also at least one battery compartment (60, 62) for holding the at least one battery (48, 50) on the suction device (10). In order to provide a suction device of this kind which can be handled in a user-friendly manner, the invention proposes that the suction device (10) comprises a filter cover (74) which be moved from a closed position, in which the at least one filter element (32) is covered, to a removal position, in which the at least one filter element (32) can be removed from and inserted into the suction device (10) on the clean-room side, and vice versa, and which filter cover (74) comprises the at least one battery compartment (60, 62) for the at least one battery (48, 50).
