Dual Dusting Head Holder With One-Hand Angle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices with telescoping handles and adjustable heads are cumbersome to use, requiring two hands to adjust the angle and lack the ability to operate dual dusting heads independently for various cleaning tasks.
Innovation Solution
A cleaning tool with a telescopic support system featuring two separate shafts that are spring-loaded for easy extension and collapse, allowing for independent adjustment of dual dusting heads with a single hand, enabling efficient cleaning of both floors and furniture with multiple cleaning pads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strong locking device is used for angle adjustment, then the duster head can be securely locked at various angles, but the adjustment requires two hands and the consumer's hand must come near to the soiled dusting heads
Solution Approach 1:
The dusting head is designed to automatically lock into angular positions relative to the handle without requiring manual intervention. The system uses a series of spaced slots in the handle and corresponding locking elements on the dusting head that engage automatically when the head is positioned at predetermined angles, allowing the device to service itself rather than requiring two-handed operation
Solution Approach 2:
The angle adjustment mechanism is segmented into discrete predetermined angular positions rather than requiring continuous adjustment. The slots are spaced at specific intervals around the handle, creating distinct locking positions that simplify the adjustment process while maintaining secure locking at each position
2Device complexity
If a single dusting head is used, then the device structure is simpler, but it cannot accommodate alternative dusting tasks requiring dual heads operating independently
Solution Approach 1:
The cleaning device is designed with a universal mounting system that can accommodate one or two dusting heads depending on the cleaning task. The forward mount includes a second support head with its own independent pivot and locking mechanism, allowing the single device to perform multiple functions - single head for simple dusting, dual heads for simultaneous floor and furniture dusting, or alternative angular configurations for different surface types
Solution Approach 2:
The dusting head mounting system is designed to be dynamically reconfigurable. The second support head can be pivoted to different angular positions and locked independently, allowing the device to adapt its configuration based on the cleaning task. This dynamic reconfiguration capability enables versatility without permanently increasing structural complexity
3Adaptability or versatility
If the handle is telescoping, then the device can be extended for floor dusting and collapsed for furniture dusting, but the extension mechanism increases device complexity
Solution Approach 1:
The telescoping handle uses a nested construction where the second extension piece fits within the first extension piece, and the shank fits within the second extension piece. This nested doll-style arrangement allows multiple handle length configurations while minimizing the overall space required and reducing the complexity of the extension mechanism compared to alternative designs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a user-friendly, all-in-one cleaning system that can be easily extended for ceiling dusting and collapsed for furniture dusting, allowing for effective cleaning of large surfaces with dual dusting heads that can be adjusted independently without requiring two hands.
Implementation Method 1
The shafts are releaseably locked together by at least one spring loaded engaging projection extending from the second shaft into a slot on the first shaft

AI summary
A cleaning tool 210 designed to be used with at least one cleaning implement/replaceable dusting sleeve/cleaning mitt or cleaning pad 11 is disclosed. The cleaning tool 210 includes a telescoping support 209 comprised of a plurality of telescopingly received shafts or sections (212, 213, 214, 215). The shafts 212, 213, 214 and 215 may be freely extended into a locked fully extended position 201 and released via depression of a first engaging projection 239. A primary support head 216 and secondary support head 218 are pivotally mounted to the forward mount 240 on a single gear 274 and releasbly locked together.
