V-Shaped Animal Waste Tool with Nested Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal waste collection devices fail to provide effective sanitation solutions, particularly for elderly and disabled individuals, and are inadequate for urban environments where natural relief areas are scarce, leading to sanitation and nuisance issues.
Innovation Solution
An animal waste collecting tool with an elongated shaft, a clasp for disposable bags, a semi-circular member with hooks for securing bags, and a V-shaped support member that connects to the semi-circular member, allowing for easy bag handling and secure containment of waste, along with optional features like telescopic and retractable designs for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing animal waste collection devices are used, then waste collection is possible, but sanitation effectiveness is inadequate and handling difficulty increases for elderly and disabled individuals
Solution Approach 1:
The disposable bag is nested within the semi-circular member, with the bag opening receiving the semi-circular member's opening. The hooks are nested within the bag structure, with forward-facing hooks engaging the bag opening and rearward-facing hooks engaging drawstrings. This nested arrangement ensures secure containment while allowing easy insertion and removal of bags by users of any ability level.
Solution Approach 2:
The dual-hook system automatically secures the bag without requiring complex manual operations. The forward-facing hooks engage the bag opening passively when the bag is inserted, while rearward-facing hooks engage drawstrings that automatically tighten to secure the bag. This self-securing mechanism eliminates the need for complex fastening operations, making the device easily operable by elderly and disabled individuals while ensuring reliable sanitation containment.
2Adaptability or versatility
If simple collection devices are used, then device complexity is low, but adaptability for different users and environments is insufficient
Solution Approach 1:
The device is segmented into distinct functional components: the elongated shaft for reach, the semi-circular member for bag reception, multiple forward-facing hooks for securing bag openings, and rearward-facing hooks for engaging drawstrings. This segmentation allows each component to perform its specific function efficiently, adapting to different user needs without requiring complex integration or adjustment mechanisms.
3Reliability
If secure bag containment is implemented, then waste containment reliability improves, but ease of bag removal decreases
Solution Approach 1:
The secure containment is achieved through hooks that are integrated into the semi-circular member structure rather than being separate fastening components. The forward-facing hooks are extracted as fixed features of the semi-circular member, while rearward-facing hooks are positioned to engage drawstrings. This extraction approach allows the bag to be securely held during use while enabling simple removal by simply pulling the bag away, which automatically disengages the hooks without requiring manual unfastening operations.

AI summary
An animal waste collecting tool for improved sanitization includes an elongated shaft having an upper end and a lower end. The upper end connects to an attachment member that is for securing the tool with a user's arm. The lower end connects to a V-shaped support member wherein two legs of the V-shaped support member are connected to a semi-circular member. On the bottom surface of the semi-circular member, there are a plurality of hooks on the bottom surface of the semi-circular member, each of the plurality of hooks being biased in the forward direction. Another hook being biased in the rearward direction is inside the tip between two legs of the V-shaped support member, for securing a disposable bag on the semi-circular member in conjunction with the plurality of hooks on the bottom surface of the semi-circular member.
