Dirt container for a hand vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held vacuum cleaners face issues with the susceptibility of dirt containers to damage during emptying and the cumbersome process of removing dirt without unintended dust and dirt spillage, with existing solutions being inadequate in terms of user-friendliness and flexibility.
Innovation Solution
A dirt container design for hand-held vacuum cleaners that includes a first unit with a dirt container, separator, and inlet nozzle, which can be coupled to a motor-fan unit via a connecting device, allowing for flexible use, reversible airflow, and modular assembly, including options like centrifugal separators or dust filter bags for improved handling and suction power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dirt container is integrated into the hand-held vacuum cleaner body, then the structure is compact and simple, but the dirt container becomes susceptible to damage during emptying and difficult to remove without dust spillage
Solution Approach 1:
The vacuum cleaner is divided into separable modules: the dirt container can be detached from the main body as a separate unit, allowing easy emptying without damage risk while maintaining compact integration during use
2Ease of repair
If reusable dust filter bags are removed and emptied, then the dirt container can be cleaned, but the process requires multiple cumbersome steps and time
Solution Approach 1:
The dirt container is extracted as a separate removable module from the vacuum cleaner body, allowing users to quickly detach and empty it directly into a dustbin without complex disassembly or multiple steps
3Ease of operation
If the dirt container is designed to be separable from the motor unit, then emptying becomes easier, but the device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The vacuum cleaner is segmented into separable modules connected by simple coupling mechanisms that enable easy detachment for emptying while maintaining overall structural simplicity
Solution Approach 2:
The coupling mechanism allows dynamic transition between connected and separated states, enabling the dirt container to be easily detached for emptying and reconnected for operation
