Suction device, in particular a vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices, such as vacuum cleaners, often require manual handling of large debris and waste, especially in industrial settings, which can be inefficient and labor-intensive.
Innovation Solution
The design incorporates a housing unit with both a standard intake opening and a larger dirt opening, allowing for simultaneous suction through the intake opening and additional filling of a dust trap container via the dirt opening, which can be used for disposing of larger debris without losing suction power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single intake opening is used for both suction and debris disposal, then the device structure is simple, but multiple users cannot operate simultaneously and suction power is lost when loading debris
Solution Approach 1:
The single intake opening is divided into two separate openings: a first opening for suction operations and a second opening for debris disposal. This segmentation allows multiple users to operate the device simultaneously without interfering with each other, while maintaining simple overall device structure.
Solution Approach 2:
The housing unit is designed to accommodate multiple functions through its opening configuration. The first opening serves suction functionality while the second opening serves debris disposal functionality, enabling the device to handle both fine dust extraction and large debris removal operations simultaneously.
2Productivity
If the dust collection container is filled through the intake opening, then the device structure remains simple, but suction power is lost during the filling process
Solution Approach 1:
The filling function is separated from the suction function by providing a dedicated second opening for debris disposal. This allows the dust collection container to be filled without blocking the first opening, maintaining continuous suction power during the filling process.
Solution Approach 2:
The suction operation continues uninterrupted during debris disposal and container filling because the first opening remains open and functional. The second opening handles all filling operations, ensuring the useful action of suction remains continuous throughout the operating cycle.
3Productivity
If manual tools like brooms and shovels are used for debris handling, then the device structure remains simple, but labor intensity increases and cleaning efficiency decreases
Solution Approach 1:
The suction device is designed to perform multiple functions: it can extract fine dust through the first opening and dispose of large debris through the second opening. This multi-functionality eliminates the need for separate manual tools like brooms and shovels, significantly improving cleaning efficiency and reducing labor intensity.
Solution Approach 2:
The functions of dust collection and debris disposal are merged into a single device with coordinated opening operations. The housing unit structure integrates both functions, allowing operators to handle both fine dust and large debris using one machine rather than multiple separate tools.

AI summary
The invention relates to a suction device, in particular a vacuum cleaner, comprising at least one drive unit (12a; 12b; 12c; 12d) for generating a suction flow, comprising at least one housing unit (14a; 14b; 14c; 14d) forming at least one suction opening (16a; 16b; 16c; 16d), which is provided for suctioning, in particular contaminated, ambient air by means of the suction flow in at least one operating state of the drive unit (12a; 12b; 12c; 12d), and comprising at least one dust collection container (18a; 18b; 18c; 18d) arranged in the housing unit (14a; 14b; 14c; 14d) for receiving dirt separated from the suction flow. According to the invention, the housing unit (14a; 14b; 14c; 14d) also forms at least one dirt opening (20a; 20b; 20c; 20d) which is different from the suction opening (16a; 16b; 16c; 16d), and which is provided for filling the dust collection container (18a; 18b; 18c; 18d) in the at least one operating state.
