Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grooming devices for animals and other objects face issues such as manual hair removal, reduced efficiency due to hair buildup, safety hazards from sharp edges, and lack of a mechanism for automatic hair ejection, leading to discomfort and potential avoidance by animals during grooming.
Innovation Solution
A self-ejecting grooming device with hair collecting elements and dislodging elements that automatically uncover and eject collected hair, featuring a slotted cover and compression springs to facilitate easy hair collection and removal, along with an optional vacuum attachment for rapid hair removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual hair removal from comb teeth is required, then device structure can be simple, but grooming efficiency decreases and time is lost
Solution Approach 1:
The comb automatically ejects collected hair through a spring-loaded mechanism that propels the comb forward, causing hair to be discharged from the teeth without manual intervention. The system serves itself by using the comb's own motion and spring energy to remove the burden of collected hair.
Solution Approach 2:
The spring mechanism is pre-loaded during normal combing operations, storing elastic potential energy. When the comb encounters resistance or is pulled backward, the spring automatically releases, propelling the comb forward to eject hair before it becomes a burden on grooming efficiency.
2Productivity
If comb teeth are exposed for effective grooming, then grooming effectiveness improves, but safety hazard increases due to sharp edges
Solution Approach 1:
The comb teeth dynamically transition between exposed and covered states. During effective grooming, teeth are exposed to engage hair. When hair accumulates or during ejection cycles, the comb moves forward and spring mechanism causes teeth to be covered or retracted, reducing exposure of sharp edges to the animal skin.
Solution Approach 2:
The comb operates in periodic cycles of hair collection and hair ejection. During collection phase, teeth are exposed for effective grooming. During ejection phase, the spring-loaded mechanism propels the comb forward, causing periodic exposure of teeth that simultaneously achieves hair removal and limits continuous exposure of sharp edges, reducing safety hazards.
3Quantity of substance
If hair accumulates on comb teeth, then more hair can be collected, but grooming efficiency decreases due to manual cleaning needed
Solution Approach 1:
The comb automatically removes accumulated hair through spring-loaded propulsion that discharges hair from the teeth. This self-service mechanism eliminates the need for manual cleaning interruptions, allowing the comb to maintain high hair collection capacity while continuously preserving grooming efficiency.
Solution Approach 2:
The spring mechanism enables continuous grooming action without interruptions for manual hair removal. The comb continuously collects hair and automatically ejects it through periodic spring-driven movements, maintaining uninterrupted grooming efficiency while accumulating and disposing of large quantities of hair.
4Productivity
If blade edges are sharp for effective de-shedding, then hair removal effectiveness improves, but risk of injury to operator and animal increases
Solution Approach 1:
The blade dynamically transitions between active and protected states. During hair removal, sharp edges are exposed for effective de-shedding. During ejection and when not in use, the spring mechanism propels the comb forward, causing blades to be covered or retracted, reducing continuous exposure of sharp edges and minimizing injury risk to both operator and animal.
Solution Approach 2:
The blade operates periodically with sharp edges exposed only during necessary hair removal contact. The spring-loaded ejection mechanism creates periodic cycles where blades are exposed for effective de-shedding, then automatically covered during hair discharge, limiting the duration of sharp edge exposure and reducing injury risk while maintaining removal effectiveness.

AI summary
A grooming device includes hair collectors and a scraper. The scraper uncovers the hair collectors when the device is pressed down for use, and scrapes the hair collectors to eject hair collected when the device is released. Ejection of collected hair can also be controlled manually. A collection chamber may be provided, and multiple combs may be mounted on a rotatable dowel that recede within the rotatable barrel, or with sliding plates around and offset from the dowel as the dowel is rotated. A door or window on a surface of the collection chamber can be opened to empty the chamber of collected hair.
