Pet Waste Retrieval Device with Self-Latching Bag Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet waste retrieval devices are unsanitary, require special bags, are limited in functionality, and are bulky and complex, lacking reliable bag closure and versatility in handling methods.
Innovation Solution
A lightweight, compact device capable of catching, scooping, and picking up pet waste using a reusable disposable bag that fully closes, allowing multiple uses without special bags, featuring a handle with latching mechanisms, a flexible restraint system, and an elastic membrane for secure bag containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a disposable bag is interposed between the handling device and the waste, then the device remains sanitary, but the user must fit a fresh bag on the device prior to each use requiring effort
Solution Approach 1:
The device automatically secures the disposable bag onto the handle through a self-latching mechanism. The bag inclusion means and latching means work together to automatically attach and secure the bag without requiring manual fitting effort from the user, thereby maintaining sanitary conditions while eliminating the effort of manual bag attachment.
Solution Approach 2:
The device is pre-configured with a bag inclusion means and latching means that are ready to automatically secure the bag upon insertion. This preliminary preparation eliminates the need for manual bag fitting during use, as the system is designed to automatically perform the bag attachment action when the bag is inserted.
2Productivity
If the device is designed for scooping the waste, then it can remove waste effectively, but it is not functional for either catching or picking up the waste
Solution Approach 1:
The device incorporates multiple functional components including a scoop means for scooping waste, a bag inclusion means for catching waste in a bag, and a retrieval means for picking up waste. This multi-functional design allows the single device to perform all three waste handling operations (scooping, catching, and picking up), eliminating the need for separate devices for different waste removal methods.
3Reliability
If the device provides reliable bag closing, then the bag remains secure between uses, but the device becomes more complex
Solution Approach 1:
The latching means and bag closing means are merged into a single integrated mechanism. The same latching components that secure the bag onto the handle also perform the bag closing function, eliminating the need for separate closing mechanisms and reducing overall device complexity while maintaining reliable bag closure.
4Weight of moving object
If the device is made compact and light weight, then it can be comfortably carried along, but the device becomes simpler and may lack reliable bag closing
Solution Approach 1:
The device utilizes a flexible membrane as part of the bag closing means. This thin, flexible component provides reliable bag closing through its elastic properties while adding minimal weight and volume to the device, maintaining compactness while ensuring secure bag closure.

Implementation Method 1
a compression spring disposed between the pull and the handle
Implementation Method 2
a compression spring disposed between the pull and the handle
Implementation Method 3
an elastic membrane disposed over at least one end of said hole
Implementation Method 4
said flexible member comprises of two spring bands having one end attached to the pull and a string disposed between other ends of said spring bands where a length of the string is comparable to a length of the flexible restrain

AI summary
A device for animal waste retrieval comprises a handle having a first latching member with a releasing member disposed at a first end of a guide, a support having a second latching member and a bag gripper disposed at a second end of the guide surface with a pull slidely coupled to it and biased toward the second end, an elongated flexible restrain with apertures proximate to its ends, wherein the restrain is so disposed that the apertures are substantially symmetrical to the support and generally opposite to the second end, and a flexible member is inserted through the apertures and attached to the pull thereby forming a loop. The device is simple, light-weighted, entirely sanitary, capable to pick up with one bag or more times, scoop, and catch the waste, comfortable and unobtrusive in use.
