Dog Walking Bag Gravity Waste Dispensing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog walking bags require users to manually handle and empty plastic waste bags, which can be unpleasant and unsanitary.
Innovation Solution
A dog walking bag with a central waste-holding compartment accessible from both top and bottom, featuring removable flaps that allow gravity to dispel full waste bags without user contact, along with additional compartments for items like treats and identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bag has a single opening for depositing waste bags, then the structure is simple, but the user must manually handle and empty full waste bags which is unpleasant and unsanitary
Solution Approach 1:
The bag is divided into two separate openings: a top opening for depositing full waste bags and a bottom opening for extracting them. This segmentation allows the user to deposit waste bags without manually emptying them, as the bottom opening enables gravity-assisted extraction. The segmentation of functions between two openings resolves the contradiction by improving ease of operation while maintaining relatively simple structure.
Solution Approach 2:
Instead of the conventional single opening where both deposition and emptying occur, the invention inverts the approach by providing separate openings for each function. The bottom opening serves the unconventional purpose of waste bag extraction rather than deposition, enabling users to empty the bag without direct contact with full waste bags.
2Productivity
If the bag provides easy access to full waste bags for emptying, then the user can quickly dispose of waste, but the user must manually handle the full waste bags which is unsanitary
Solution Approach 1:
By separating the deposition opening (top) from the extraction opening (bottom), the system allows rapid disposal of waste bags through gravity-assisted extraction at the bottom opening, while the user never needs to directly handle full waste bags. This maintains high productivity while eliminating sanitation issues.
Solution Approach 2:
The bottom opening acts as an intermediary mechanism that enables the transfer of full waste bags from the bag interior to the exterior without requiring the user to make direct contact. The opening serves as a mediator between the storage compartment and the external environment, facilitating quick disposal while protecting user hygiene.
3Adaptability or versatility
If the bag has multiple compartments for organizing accessories, then the organization and storage capability is improved, but the device complexity increases
Solution Approach 1:
The bag incorporates multiple compartments serving different functions: a first compartment for full waste bags, a second compartment for treats, and a third compartment for identification and accessories. Each compartment is accessible through its own opening, allowing the bag to handle multiple tasks (waste collection, treat storage, identification carrying) simultaneously, thereby improving versatility while keeping the overall structure manageable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the collection and disposal of dog waste without manual handling, keeping the user clean and providing a convenient storage solution for various dog walking accessories.
Implementation Method 1
the bottom flap is manipulated to uncover the bottom opening, allowing the full waste bags to fall out of the central waste-holding compartment by force of gravity

AI summary
A dog walking bag includes a central waste-holding compartment that is accessible from openings at the top end and bottom end of the compartment. The dog walking bag further includes a top flap, removably covering the top opening, and a bottom flap, removably covering the bottom opening. When using dog walking bag, a user deposits plastic waste bags containing animal waste (hereinafter “full waste bags”) into the central waste-holding compartment through the top opening. When a time arrives to empty the central waste-holding compartment of full waste bags, the bottom flap is manipulated to uncover the bottom opening, allowing the full waste bags to fall out of the central waste-holding compartment by force of gravity. In this way, a user is able to empty the central waste-holding compartment of full waste bags without having to touch or manually handle the full waste bags during the emptying process.
