Cleaning Device with Longitudinal Ejector for Hygienic Pad Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices require users to bend down to detach soiled cleaning pads, leading to unpleasant and unhygienic conditions.
Innovation Solution
A cleaning device with a handle and pivotally connected cleaning head, featuring a detaching device that moves along the handle's longitudinal axis to change between cleaning and detaching positions, allowing for pad replacement without bending, using an ejector element to push the pad away from the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pushing unit is provided at the cleaning head to remove soiled webs, then the cleaning function is improved, but the user must bend down to operate it which causes ergonomic and hygienic problems
Solution Approach 1:
The patent introduces a detaching device with an ejector element as an intermediary mechanism between the user and the soiled cleaning pad. The ejector element is movable along the longitudinal axis and can be actuated by the user from a comfortable position to push the soiled pad away from the cleaning head, eliminating the need for the user to bend down and directly contact the contaminated pad.
2Ease of operation
If the detaching device is moved along the longitudinal axis from cleaning position to detaching position, then pad detachment is achieved, but the device complexity increases
Solution Approach 1:
The detaching device incorporates a movable ejector element that can transition between a cleaning position (where it is retracted and does not interfere with the cleaning pad) and a detaching position (where it protrudes to push the pad away). This dynamic positioning allows the device to maintain simplicity during normal cleaning operations while providing the detachment function when needed, balancing operational ease with structural simplicity.

AI summary
A cleaning device having a handle extending along a longitudinal axis and a cleaning head. The cleaning head is in connection with the handle and is configured such that a cleaning pad is detachably fastenable to the cleaning head. The cleaning device further has a detaching device that is movably mounted to the handle and is configured to be moved along the longitudinal axis with respect to the handle from a cleaning position, in which a cleaning pad being fastened to the cleaning head remains fastened to the cleaning head, into a detaching position, in which a cleaning pad being fastened to the cleaning head is detached from the cleaning head.
