Power driven duster and cleaner apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-driven dusting and cleaning apparatuses face issues such as water infiltration into the drill motor when used in wet conditions, protruding parts and sharp edges that can snag clothing or cause injury, difficulty in disassembling for storage, and hand fatigue due to prolonged gripping of the hand guide member, as well as wobbling of the cleaning head during operation.
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 member 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 improved water retention and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the extension member is made long to reach high or low areas, then the cleaning capability is improved, but the device becomes difficult to control and causes hand fatigue
Solution Approach 1:
The extension member is divided into multiple telescoping segments that can be extended or retracted independently. This segmentation allows the device to reach high or low areas when needed while maintaining a compact, controllable size during normal operation, thus resolving the contradiction between reachability and ease of control.
Solution Approach 2:
The extension member incorporates a telescoping mechanism with adjustable length, transforming it from a static to a dynamic structure. The operator can extend the member to reach difficult areas and retract it for easier handling and storage, dynamically adapting the length to the operational requirements.
2Length of moving object
If the hand guide member is made slender to fit through tight spaces, then the ability to reach narrow areas is improved, but the hand guide member can slide off the extension member
Solution Approach 1:
The hand guide member features an asymmetric cross-sectional shape that does not match the circular profile of the extension member. This asymmetric design allows the hand guide to fit through tight spaces while the non-circular profile prevents it from rotating or sliding off the extension member, simultaneously achieving accessibility and retention.
Solution Approach 2:
Instead of making the extension member larger to prevent the hand guide from sliding off, the solution inverts the approach by designing the hand guide member itself with a non-circular profile that naturally prevents disengagement. This inversion allows the hand guide to remain slender for accessing tight spaces while inherently preventing it from sliding off.
3Stability of the object's composition
If the extension member is made rigid to maintain stability, then the cleaning head stability is improved, but water can drip down and damage the drill motor
Solution Approach 1:
A protective barrier or shield is introduced as an intermediary element between the extension member and the drill motor. This barrier intercepts and redirects water before it can reach the motor, allowing the extension member to remain rigid for stability while protecting the motor from water damage.
Solution Approach 2:
The vulnerable electrical components (drill motor) are extracted or isolated from the area where water can reach them. By separating the motor from the water-exposed extension member area, the system maintains the rigidity needed for stability while eliminating the water damage risk to the motor.
4Ease of manufacture
If the device is made as a single integrated unit for simplicity, then the ease of manufacture is improved, but the device is difficult to disassemble for storage and component replacement
Solution Approach 1:
The device is divided into distinct modular segments (handle, extension member, cleaning head) that can be easily assembled and disassembled. This segmentation maintains manufacturing simplicity through standardized components while enabling easy disassembly for storage and component replacement, resolving the contradiction between manufacturing ease and operational flexibility.

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 one or more elongated extension members telescoped within one another and fixed relative to one another by a clamping connector, the first extension member having a first connecting member at one end constructed to be inserted into and attachable to the chuck and a second member at the opposing end of the extension members constructed to be attachable to the head of a conventional dusting device. The apparatus further includes a foam covered tubular hand guide member fitted about the first extension member and constructed to slide along the first extension member. The first connecting member is constructed having a shield to prevent water from dripping down the extension members and into the power drill, and to prevent the guide member from sliding off the extension member when the extension member is not attached to the power drill.
