Suction device with a dirt collection container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile suction devices for construction or workshop use require cumbersome disposal methods, often releasing dust and dirt into the environment when emptying, as they need to be moved as a whole to a disposal site, which is inefficient and unhygienic.
Innovation Solution
A mobile suction device design featuring a detachable, compact dirt collection container that fits into the suction device housing, allowing for easy removal and disposal without needing to move the entire device, equipped with a main filter that prevents dust from entering the suction unit and can be cleaned, and a container attachment for additional storage and operational elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire suction device is moved to a disposal site for emptying, then all dirt can be disposed of, but the device becomes cumbersome and dust is dispersed into the environment
Solution Approach 1:
The suction device is divided into a stationary housing containing the suction unit and a removable dirt collection container. This segmentation allows the dirt container to be separated and disposed of independently at different locations, eliminating the need to move the entire device and preventing dust dispersal during transport.
Solution Approach 2:
The dirt collection container is extracted as a separate removable component from the suction device housing. This extraction enables the container to be taken to disposal sites independently while the main housing remains stationary, solving both the mobility and dust containment problems.
2Device complexity
If the suction device is designed as a single integrated unit, then structural simplicity is achieved, but disposal requires moving the entire heavy device
Solution Approach 1:
The device is segmented into a heavy stationary housing and a lightweight removable dirt container. This segmentation reduces the weight that must be moved during disposal operations while maintaining the functional integrity of the complete system when assembled.
3Object-affected harmful factors
If a filter bag is used to collect dirt, then dust is contained, but the filter bag must be removed and disposed of separately
Solution Approach 1:
The filter bag is merged with the dirt collection container, forming an integrated assembly where the filter bag lines the container interior. This combination allows both the filter bag and collected dirt to be removed and disposed of as a single unit, simplifying the disposal operation while maintaining effective dust containment.
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 design simplifies disposal by allowing the lightweight dirt collection container to be carried to a disposal site separately, reducing dust dispersal and enhancing hygiene, while the main filter ensures efficient dust retention and the container attachment provides additional storage and operational functionality.
Implementation Method 1
a suction unit (24) arranged in the suction device housing (21) for generating a suction flow
Implementation Method 2
a filter arrangement (26) for retaining dirt contained in the suction flow
