Hand Vacuum Motor Layout for Removable Cyclone Bin Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand vacuum cleaners require users to remove the cyclone bin assembly for emptying, which necessitates disconnecting cleaning tools and can be cumbersome, as the cyclone bin is not removable in pod-style designs.
Innovation Solution
A hand carryable surface cleaning apparatus with the suction motor positioned proximate the handle, allowing for angled orientation and a portion of the dirt collection chamber to be positioned under the suction motor, enabling easier handling and increased dirt capacity while maintaining the cyclone bin's removability for emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the cyclone bin assembly is made removable for emptying, then ease of maintenance is improved, but device complexity increases and ease of operation deteriorates due to required disconnection of cleaning tools
Solution Approach 1:
The cyclone bin assembly is segmented as a separate removable component from the main vacuum body, allowing it to be detached and emptied independently. This segmentation enables maintenance without requiring disconnection of cleaning tools attached to the vacuum system.
Solution Approach 2:
The cyclone bin assembly is designed to nest within the main vacuum body housing, allowing it to be stored compactly when attached and easily removed when emptying is needed. The nested design maintains a compact overall form factor while enabling independent access to the bin for maintenance.
2Ease of operation
If the suction motor is positioned proximate the handle, then ease of operation is improved by reducing hand weight, but device complexity increases due to reconfigured air flow path
Solution Approach 1:
The air flow path is routed through three-dimensional space around and along the suction motor in unconventional directions, rather than following a simple linear path. This allows the motor to be positioned optimally near the handle for balance while maintaining efficient airflow from the cyclone bin through the motor to the exhaust.
Solution Approach 2:
The air flow path design creates localized flow channels and passages specifically adapted to the motor's position near the handle. The housing and internal structures are shaped to guide airflow efficiently through this non-traditional layout, optimizing local flow characteristics around the motor assembly.
