Stackable Suction Housing With Removable Dust 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 modular suction device design featuring a container attachment that can be stacked on top of the suction housing, providing additional storage for the suction hose, electrical connections, and dust/dirt collection, with integrated carrying handles and coupling mechanisms for easy transport and stacking, allowing for separate disposal of the dirt collection container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction device is designed as a single integrated unit, then structural simplicity is maintained, but mobility and ease of transport are reduced due to bulkiness
Solution Approach 1:
The suction device is divided into separate modular components: a base unit containing the motor and a removable container attachment for dust collection. This segmentation allows the main body to remain compact while the container can be detached for disposal, improving mobility without requiring complete disassembly of the entire device.
Solution Approach 2:
The dust collection container is extracted as a separate removable component from the main suction device. This allows the container to be taken out independently for disposal at different locations, eliminating the need to transport the entire suction device to disposal sites and significantly improving ease of operation.
2Ease of operation
If the suction hose is stored externally, then accessibility is improved, but the device becomes bulkier and harder to transport
Solution Approach 1:
The suction hose is stored nested within the container attachment, which itself attaches to the base unit. This nested arrangement keeps the hose accessible when needed while minimizing the overall volume of the device during transport, as all components are compacted into a nested configuration.
3Productivity
If the entire suction device is transported to disposal sites, then all components are available, but time and effort are wasted transporting unnecessary components
Solution Approach 1:
The dust container is extracted as a separate removable component that can be disposed of independently. This allows users to transport only the lightweight container to disposal sites rather than the entire suction device, significantly reducing transport time and effort while maintaining full functionality.
Solution Approach 2:
The device is segmented into a permanent base unit and a disposable container attachment. This segmentation enables selective transport of only the necessary components (the container when full) rather than the entire system, improving disposal efficiency by eliminating unnecessary transport of the motor and control components.
