Stackable Vacuum Housing With Detachable Dirt Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile suction devices are cumbersome and inefficient, particularly when handling bulky suction hoses and dirt collection, as they often require moving the entire device to disposal sites and lack convenient storage and handling solutions.
Innovation Solution
A mobile suction device with a detachable container attachment that provides additional storage for the suction hose, electrical connections, and dust/dirt collection, featuring through-openings for easy connection to the suction inlet and a carrying handle for improved portability, allowing the suction device to be broken down for easier transport and disposal of collected dirt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the suction device is designed as a single integrated unit for dirt collection, then the suction capacity is sufficient, but the device becomes cumbersome and difficult to transport to disposal sites
Solution Approach 1:
The suction device is divided into two main segments: a stationary suction device housing containing the suction unit, and a detachable container attachment for dirt collection. This segmentation allows the dirt collection container to be separated from the suction device and transported independently to disposal sites, solving the problem of moving bulky collected dirt while maintaining sufficient dirt collection capacity during operation.
Solution Approach 2:
The container attachment designed according to the invention can be completely detached from the suction device housing. This extraction principle allows the dirt collection container to be removed and transported separately, eliminating the need to move the entire suction device to disposal sites and significantly improving transportability.
2Ease of operation
If the suction hose is stored externally on the suction device, then accessibility is improved, but the device becomes bulkier and less portable
Solution Approach 1:
The container attachment features a receiving cavity designed to nest and store the suction hose when not in use. This nesting principle allows the hose to be compactly stored within the container attachment's internal space, preventing it from protruding excessively and reducing the overall device footprint while maintaining accessibility during operation.
3Adaptability or versatility
If the suction device housing includes all functional components, then the device is self-sufficient, but it lacks adaptability for additional functions
Solution Approach 1:
The container attachment is designed as a universal platform that can perform multiple functions: storing the suction hose, providing additional dirt collection capacity, housing electrical connection cables, and serving as a mounting base for operating elements or display elements. This multi-functionality principle allows the base suction device to remain relatively simple while gaining extensive adaptability through the versatile container attachment.
4Ease of operation
If the suction device is designed for compact storage, then portability is improved, but the suction capacity and dirt collection volume are reduced
Solution Approach 1:
By segmenting the dirt collection function into a separate detachable container attachment, the system allows the suction device housing to maintain a compact size for portability, while the container attachment provides additional dirt collection volume. The container attachment can be attached when large capacity is needed and detached when portability is the priority, resolving the contradiction between compact storage and dirt collection volume.
