Pet Waste Collection Ring with Threaded Pole Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excrement collection devices fail to effectively secure a bag around an animal without direct contact and efficiently collect excrement using a ring and hooks, and lack a receiver for coupling to a threaded pole.
Innovation Solution
A ring with an aperture supports a bag via its rim, secured by hooks, and a receiver with internal threads couples to a removable pole, allowing the bag to be positioned below an animal to collect excrement without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bag is held near an animal to catch excrement, then excrement collection is achieved, but direct contact with the bag and excrement occurs which is unsanitary and difficult to handle
Solution Approach 1:
The patent introduces a ring with hooks as an intermediary mechanism that secures the bag without requiring direct human contact. The ring acts as a mediator between the user and the bag, allowing the bag to be positioned and secured while keeping the user's hands clean and away from the excrement collection area.
Solution Approach 2:
The patent replaces direct manual manipulation of the bag with a mechanical securing system consisting of the ring, hooks, and rim fold-over mechanism. This mechanical system automatically holds the bag in place without requiring continuous manual adjustment or contact, thereby improving sanitation and ease of operation.
2Reliability
If a simple bag holding method is used, then the device is simple, but it cannot securely secure the bag around the animal
Solution Approach 1:
The patent divides the securing mechanism into distinct functional segments: the ring structure, the hooks, and the rim fold-over component. Each segment performs a specific function - the ring provides the mounting structure, the hooks secure the bag handles, and the rim fold-over ensures the bag is properly positioned. This segmentation allows for reliable bag security while keeping each individual component simple.
Solution Approach 2:
The patent combines multiple securing functions into a single integrated ring assembly. The ring simultaneously provides structural support, houses the hooks for securing bag handles, and incorporates the rim fold-over mechanism. This merging of functions achieves reliable bag security without requiring multiple separate devices, thereby maintaining simplicity.
3Adaptability or versatility
If a fixed pole attachment is used, then the structure is stable, but it cannot be easily removed or adjusted
Solution Approach 1:
The patent incorporates a threaded receiver on the ring that allows the pole attachment to be dynamic rather than fixed. The threaded mechanism enables the pole to be easily screwed onto and removed from the ring, providing adaptability for different pole lengths and configurations. This dynamic coupling maintains structural stability during use while allowing for easy adjustment and removal when needed.

AI summary
An excrement collection apparatus for collecting excrement from an animal before the excrement reaches the ground and without touching the excrement directly includes a ring which defines an aperture therein. The ring has a size and is configured to support a bag in the aperture via a rim of the bag folded over the ring. A receiver is coupled to and extends away from the ring, and an elongated pole is removably couplable to the receiver.
