Retractable Vacuum Grooming Brush for Hands-Free Hair Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet grooming devices with slicker brushes face issues of hair entanglement between bristles, requiring manual removal which can be inconvenient and unpleasant, especially when bristles are sharp or when users are allergic to pet dander.
Innovation Solution
A vacuum cleaning appliance attachment with a bristle carrier and cover, featuring retractable bristles and a conduit for air flow, allowing entangled hair to be dislodged and carried away using the vacuum's air flow, with an actuator for easy switching between stowed and deployed configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If retractable bristles are used to prevent hair entanglement, then hair removal efficiency is improved, but device complexity increases due to the need for actuators and mechanical mechanisms
Solution Approach 1:
The bristles are designed to be dynamically retractable rather than statically fixed. The bristle carrier can move relative to the bristle cover, allowing bristles to transition between extended and retracted positions. This dynamic configuration enables automatic hair ejection through vibration while maintaining simple overall structure.
Solution Approach 2:
The device uses self-service mechanisms where vibration automatically ejects entangled hair from between the bristles without requiring manual intervention. The relative movement between bristle carrier and cover during vibration creates forces that naturally dislodge and eject accumulated hair, making the system self-maintaining.
2Device complexity
If manual removal of entangled hair is required, then device complexity is reduced, but user comfort deteriorates due to contact with sharp bristles and allergens
Solution Approach 1:
The system automatically ejects entangled hair through vibration-induced relative movement between the bristle carrier and cover. This self-service mechanism eliminates the need for users to manually remove hair, thereby avoiding contact with sharp bristles and allergens while maintaining simple device structure.
Solution Approach 2:
Vibration is applied to the grooming device, causing the bristle carrier to vibrate relative to the bristle cover. This vibration creates forces that automatically dislodge and eject entangled hair from between the bristles, improving user comfort without requiring complex mechanical ejection mechanisms.
3Productivity
If bristles remain extended during grooming, then grooming effectiveness is improved, but hair entanglement increases requiring frequent manual cleaning
Solution Approach 1:
The device automatically ejects entangled hair through vibration during or after grooming operations. The relative movement between bristle carrier and cover creates forces that naturally dislodge accumulated hair, eliminating the need for manual cleaning and allowing bristles to remain extended throughout the grooming process.
Solution Approach 2:
Vibration is applied periodically or continuously during grooming to maintain bristle cleanliness. This periodic mechanical action prevents significant hair entanglement by continuously ejecting loose hair, allowing sustained grooming effectiveness without frequent manual intervention.

AI summary
An attachment for a vacuum cleaning appliance includes a head having a bristle carrier and a bristle cover. The bristle carrier includes a plurality of bristles and the bristle cover includes a plurality of apertures. The attachment includes a conduit which is connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance, a handle connected to the head, and an actuator which is depressible towards the handle to effect relative movement between the bristle carrier and the bristle cover between a stowed configuration in which the bristles are retracted relative to the bristle cover and a deployed configuration in which the bristles protrude from the bristle cover through the apertures.
