Rotatable Suction Nozzle for Handheld Vacuum Cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held suction devices lack versatility and efficiency in cleaning operations, particularly in confined spaces, due to fixed suction nozzle orientations and limited battery access.
Innovation Solution
A hand-held suction device with a pivot-bearing suction connection piece that allows rotational adjustment relative to the suction container and housing, enabling optimized alignment for cleaning in tight spaces and facilitating easy battery access through a removable and rechargeable battery holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suction connection piece is fixed relative to the suction container, then the device structure is simple, but the cleaning versatility in different spaces is limited
Solution Approach 1:
The suction connection piece is made rotatable relative to the suction container through a pivot bearing, allowing dynamic adjustment of the suction nozzle orientation. This enables the device to adapt to different cleaning scenarios (floor, upholstery, corners) without requiring multiple fixed configurations, thereby improving versatility while maintaining relatively simple device structure.
2Adaptability or versatility
If the suction nozzle orientation is fixed, then the device structure is simple, but the ability to clean in tight spaces is limited
Solution Approach 1:
The suction connection piece can be rotated via the pivot bearing to adjust the suction nozzle orientation, enabling access to tight spaces and corners that would be inaccessible with a fixed nozzle. The rotation mechanism is simple and does not significantly increase device complexity.
3Ease of operation
If the battery holder is permanently fixed, then the device structure is stable, but battery access and replacement is difficult
Solution Approach 1:
The battery holder is designed to be detachably mounted on the housing, allowing easy removal and reattachment. This provides convenient battery access for replacement or recharging while maintaining structural stability during normal operation when the battery holder is attached.
4Adaptability or versatility
If the suction connection piece is rotatable, then the cleaning flexibility is improved, but the device complexity increases
Solution Approach 1:
A pivot bearing is used to enable rotation of the suction connection piece with minimal mechanical complexity. The pivot bearing provides smooth rotation while maintaining structural integrity, achieving cleaning flexibility without significantly increasing device complexity.
