Two-Sided Duster Structure With Accessible Handle Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dusting devices, whether reusable or disposable, face challenges such as ineffective dust trapping, complex manufacturing, and user inconvenience when trying to attach handles due to internal attachment systems being difficult to access.
Innovation Solution
A duster design featuring two construction portions of unequal length joined in a facing relationship, with an external attachment system accessible for handle attachment and internal sleeves for secure attachment, allowing for easy alignment and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a duster has a single preferential cleaning side, then the structure is simple and inexpensive to manufacture, but two passes are required to clean crevices or opposed surfaces, increasing cleaning time
Solution Approach 1:
The duster is segmented into multiple cleaning sides (at least two, potentially three or four) that can be accessed by rotating the duster head. Each side has its own preferential cleaning surface, allowing the user to clean multiple surfaces including crevices and opposed surfaces without removing and reattaching the duster, thereby reducing cleaning time while maintaining manufacturing simplicity through modular construction
2Adaptability or versatility
If the attachment system is placed internally to allow 360-degree usability, then the duster can be used from all directions, but the attachment system becomes difficult for users to access and align with the handle
Solution Approach 1:
The attachment system is nested within the duster construction but extends through the outer layer, allowing the attachment interface (sleeves or other attachment means) to be accessible from the exterior while still being protected and integrated into the overall structure. This enables users to easily access and manipulate the attachment system for handling and reattachment while maintaining the ability to rotate and use the duster from multiple directions
3Ease of manufacture
If reusable dust gathering devices are designed to be cleaned and reused, then manufacturing cost is reduced, but the devices do not hold or trap dust well and require frequent cleaning
Solution Approach 1:
The duster is designed as a disposable or limited-reuse product with construction portions that can be easily replaced. The attachment system allows the handle to be removed and reattached multiple times, providing limited reusability. This approach balances manufacturing cost with dust trapping effectiveness by using synthetic fiber bundles on non-woven sheets that maintain cleaning effectiveness for a reasonable number of uses before being discarded

AI summary
A two sided duster (10) removably attachable to a handle (50). The duster (10) may have two construction portions (15), each with an inwardly facing surface joined to the other to form a laminate construction. The construction portions (15) may be longitudinally (L-L) offset. The arrangement allows an attachment mechanism associated with the inwardly facing surface to be visible to a user, so the handle (50) may be easily and removably attached to the duster (10) at the attachment mechanism.
