Sanitary Pet Feces Retrieval System with Disposable Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a sanitary and convenient system to collect pet feces during walks, especially in areas where leaving feces on sidewalks or yards is prohibited or considered impolite, as existing solutions do not provide a hygienic and efficient means of disposal.
Innovation Solution
A pet feces retrieval system featuring a disposable continuous feed-through bag and a scoop with pivotally connected jaws, where the bag covers the scoop and can be easily attached and detached for disposal, allowing for hygienic and efficient collection and removal of pet feces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a disposable bag system is implemented for feces collection, then hygiene and sanitation are improved, but device complexity increases due to the need for bag attachment and disposal mechanisms
Solution Approach 1:
The disposable bag is nested within the scoop structure, with the bag fitting inside the cupped jaws and attaching to the handle. This nesting approach allows the bag to be integrated into the existing scoop design without requiring separate complex attachment mechanisms, thereby improving hygiene while minimizing added complexity
Solution Approach 2:
The invention employs a disposable bag that can be easily attached, used, and discarded. This disposable approach eliminates the need for thorough cleaning and sanitization of the scoop after each use, significantly improving hygiene while keeping the overall system simple since the bag itself handles the contamination
2Ease of operation
If a continuous feed-through bag system is used, then ease of disposal is improved, but manufacturing complexity increases due to the continuous bag structure
Solution Approach 1:
The continuous feed-through bag is pre-formed with feed-through holes positioned at specific locations before being loaded onto the roll. This preliminary preparation allows for easy installation and disposal during use, while the manufacturing complexity is confined to the initial bag production stage rather than the usage stage
Solution Approach 2:
The continuous bag is designed with segmented feed-through holes that allow it to be easily installed on the scoop and then segmented again during disposal. The bag can be pulled through the holes to attach, used, and then easily removed and discarded, simplifying the disposal process while maintaining a relatively simple manufacturing approach
3Reliability
If the bag fully covers the scoop and wraps around the jaws, then containment effectiveness is improved, but device complexity increases due to the wrapping and attachment mechanism
Solution Approach 1:
The bag is made from a flexible material that can fully cover the scoop interior and wrap around the cupped jaws. This flexibility allows the bag to conform to the scoop's shape and secure itself around the jaws, providing reliable containment without requiring rigid structures or complex fastening mechanisms
Solution Approach 2:
The bag utilizes the third dimension by wrapping around the jaws and attaching to the handle, creating a three-dimensional containment structure. This dimensional approach provides effective containment by enclosing the collection area from multiple directions, while the wrapping mechanism itself remains relatively simple and intuitive

AI summary
A sanitary pet feces retrieval system having a disposable liner features a feces scoop having an elongated handle with a first scooping jaw and a mated, opposing second scooping jaw pivotally located on a handle second end. A lever pivots the first scooping jaw away from the second scooping jaw into an open position for retrieving feces from a ground surface. The system features a bag dispenser located on the handle. Disposable bags are sequentially located on a bag roll. A bag fully covers a scoop inner surface and wraps around to fully cover a first jaw outer surface and a second jaw outer surface. A bag upper lip is located at a first jaw posterior opening and a second jaw posterior opening via attachment to a plurality of jaw eyelets located on a jaw posterior lip.
