Telescoping Drill Duster Assembly for Wobble and Water Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-driven dusting and cleaning devices face challenges such as water ingress into the motor, protruding parts causing snagging or injury, difficulty in disassembly for storage, hand fatigue due to prolonged gripping, and wobbling of the cleaning head during operation, especially when used in wet conditions or on uneven surfaces.
Innovation Solution
A hand-held apparatus with a tubular extension member connected to a power drill, featuring a cylindrical attachment member with a circular shield to prevent water and hand guide sliding, a resilient coating for comfort, telescoping extension members with a two-piece securing mechanism to prevent wobble, and a dusting head with bundled soft fibers for efficient water retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tubular extension member is used to reach high or low areas, then cleaning coverage is improved, but water can drip down into the motor causing damage
Solution Approach 1:
A circular shield is introduced as an intermediary component between the extension member and the motor. The shield intercepts water dripping down the extension member and redirects it away from the motor, preventing water ingress while maintaining the extended reach capability for cleaning high and low areas
2Ease of operation
If the hand guide member can slide freely on the extension member, then ease of operation is improved, but the member can slide off when disconnected causing loss or injury
Solution Approach 1:
The stopping function is extracted from the extension member itself and implemented as a separate feature on the circular shield. The shield's larger diameter creates a physical stop that prevents the hand guide member from sliding off, while the hand guide maintains its ability to slide freely on the extension member during operation
3Ease of manufacture
If protruding parts are provided for connection, then ease of assembly is improved, but they can snag clothing or injure the operator
Solution Approach 1:
The circular shield acts as a protective shell that covers and rounds off the connection interface between the extension member and power drill. This eliminates sharp edges and protruding parts that could snag clothing or injure the operator, while still allowing the connection functionality to be maintained through the shield's opening
4Ease of operation
If the cleaning head is loosely attached, then ease of detachment is improved, but wobbling occurs during operation reducing cleaning quality
Solution Approach 1:
The connection system is designed with dynamic characteristics that allow for easy attachment and detachment when not in use, but provide stable, wobble-free operation when engaged. The telescoping extension members with securing mechanisms create a rigid connection during operation while maintaining user-friendly assembly and disassembly capabilities

AI summary
An improved hand held apparatus used for dusting, cleaning, polishing, and similar tasks utilizing a lightweight conventional power drill having a rotating axle with a chuck to which is attached two or more elongated extension members telescoped within one another forming a gap between adjacent extension members into which at least one band fitted about one of the elongated extension member is positioned to reduce wobble in the adjacent extension member when the axle of the power drill causes the first extension member to rotate.
