Hinged Handle Suction Assembly for One-Handed Waste Container Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canister vacuum cleaners with hinged waste collection handles require two hands to empty the waste collection container due to ergonomic limitations, making it difficult to tilt and empty with one hand.
Innovation Solution
A suction assembly with a centrally located, elongated grip handle that pivots at one end, allowing for easy, firm, and stable grip of the waste collection bowl, enabling one-handed operation to unlock, remove, and tilt the bowl for emptying, while ensuring effective locking on the vacuum cleaner housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hinged handle is mounted on the waste collection bowl, then the waste separation and collection device can be locked onto the vacuum cleaner housing, but the handle cannot provide an ergonomic position for one-handed tilting and emptying of the container
Solution Approach 1:
The handle is divided into two functional parts: a hinged portion that provides locking capability and a gripping portion that extends centrally for ergonomic one-handed operation. This segmentation allows each part to optimize its specific function while working together as an integrated unit.
Solution Approach 2:
The locking function and gripping function are merged into a single handle assembly. The hinged handle incorporates both the locking mechanism (through its articulation on the waste collection bowl) and the gripping surface (through the centrally extending gripping portion), eliminating the need for separate components.
2Ease of operation
If a centrally located handle is used for one-handed emptying, then ergonomic tilting is enabled, but effective locking of the waste separation and collection device onto the vacuum cleaner housing becomes difficult
Solution Approach 1:
The handle is designed as a dynamic component that can assume different positions and orientations. The hinged connection allows the handle to pivot between a locked position (when attached to the waste collection bowl) and an operational position (when extended for gripping). This dynamic capability enables the handle to fulfill both locking and ergonomic gripping functions.
3Reliability
If a hinged handle is used, then locking mechanism can be implemented, but the handle must be folded back to clear the waste discharge opening, requiring a second hand for emptying
Solution Approach 1:
The gripping portion of the handle extends in the median longitudinal plane of the waste collection container, utilizing the central longitudinal dimension. This dimensional arrangement allows the handle to project forward through the waste discharge opening without obstruction, eliminating the need to fold the handle back and reducing the emptying operation to a single-handed action.

AI summary
The suction assembly comprises a vacuum housing (3) and a waste separation and collection device (8) which is mounted removably relative to the vacuum housing (3). The waste separation and collection device (8) comprises a waste collection bowl (10); a gripping handle (22); and two locking members movable between a locked and unlocked position of the waste collection bowl (10). The gripping handle (22) is hinged to the waste collection bowl (10) by means of a single pivot joint (23) which defines a pivot axis, and includes a gripping portion (220) which extends substantially in a median longitudinal plane of the waste collection bowl (10), the locking members being arranged on either side of the gripping portion (220).
