Disposable Towel Cleaning Head With Clamp-Ejector Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of disposable cleaning towels for household surfaces can cause skin irritation, fingernail irritation, and exposure to undesirable and unhealthy substances, as users often need to touch soiled towels during cleaning.
Innovation Solution
A handheld cleaning device with a handle, a wedge-shaped head, clamps, and an ejector mechanism that securely holds and ejects a disposable cleaning towel, allowing for safe handling and disposal without direct contact with the soiled towel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a disposable cleaning towel is used for cleaning surfaces, then cleaning effectiveness is improved, but skin irritation and exposure to unhealthy substances occur due to direct contact with the towel
Solution Approach 1:
The cleaning device introduces an intermediary mechanism (the holder with clamp and ejector system) between the user's hand and the cleaning towel. The user holds the device handle rather than touching the towel directly, while the towel is secured to the device head through the clamp mechanism. This intermediary structure eliminates direct skin contact with the towel's contaminants while preserving cleaning effectiveness.
2Ease of operation
If the cleaning towel is held directly in the hand, then ease of operation is improved, but skin contact with soiled towel causes irritation and health issues
Solution Approach 1:
The cleaning system is segmented into distinct functional components: a handle for user gripping, a head for towel attachment, a clamp mechanism for securing the towel, and an ejector for disposal. This segmentation allows the user to interact only with the clean handle portion while the towel and its contaminants remain isolated on the head portion, maintaining ease of operation without skin contact hazards.
3Object-affected harmful factors
If the cleaning device includes an elongated handle, then user safety is improved by preventing contact with soiled towel, but device complexity increases
Solution Approach 1:
The device incorporates self-service features that reduce operational complexity despite the added components. The clamp mechanism automatically secures the towel when the ejector is actuated, and the ejector itself serves dual functions: removing the used towel and simultaneously presenting a fresh towel from the roll. This self-service automation minimizes the user's interaction complexity while maintaining protective benefits.
4Reliability
If clamps are used to secure the cleaning towel to the head, then secure attachment is improved, but device complexity increases due to additional moving parts
Solution Approach 1:
The clamp mechanism is merged with the ejector system into an integrated assembly. The clamp's securing function and the ejector's disposal function are combined into a single operational sequence: actuating the ejector both releases the clamp to free the used towel and simultaneously advances the next towel. This merging reduces operational steps and simplifies user interaction despite the presence of multiple mechanical components.

AI summary
A cleaning device operable for use with a disposable cleaning towel is provided. The cleaning device includes a handle, a head, first and second clamps, and an ejector. The handle extends between a proximal end portion and a distal end portion. The head is disposed relative to the distal end portion of the handle. The head defines a head surface over which the disposable cleaning towel is fixed during use of the cleaning device. The head defines a head cavity and a head aperture extending between the head cavity and the head mating surface. The first and second clamps are disposed relative to the head, and each are selectively moveable between a closed position and an open position. In their respective closed positions, at least a portion of each of the first and second clamps is operable to abut the head surface and hold the cleaning towel in place. In their respective open positions, each of the first and second clamps is positioned away from the head surface. The ejector is disposed relative to the head, and is selectively moveable between a stowed position and a deployed position. In the stowed position, the ejector is disposed entirely within the head cavity. In the deployed position, at least a portion of the ejector extends through the head aperture and extends outward relative to a plane defined by the head surface.
