Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing animal waste carrying bags attached to leashes often slide down, are uncomfortable to handle, or pose a risk of spillage, as they attach too close to the user's hand, making it difficult to manage both hands for walking a dog or climbing.

Innovation Solution

A line-attachable bag with adjustable attachment loops and a strap system that allows for secure positioning on a leash or rope, featuring a first compartment for waste and a secondary compartment for other items, with fastener components and elastic materials to maintain stability and accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bag attaches too close to the user's hand, then it is easy to access, but it creates uncomfortable feeling and risk of spillage

Engineering Contradiction:

Improveaccessibility of bagVSAvoidrisk of spillage and discomfort

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs dynamic adjustment mechanisms including movable clips and adjustable straps that allow the bag position to be changed along the leash. This enables the user to optimize the attachment position dynamically - placing it far enough to prevent spillage and discomfort, yet accessible when needed. The adjustable nature resolves the contradiction by allowing position optimization rather than fixed placement.

Inventive Principle:

Principle #15Dynamics

2Length of moving object

If the bag slides down the leash, then it may be positioned farther from the hand, but it becomes difficult to control and may fall off

Engineering Contradiction:

Improvedistance from user's handVSAvoidposition stability on leash

Core Design Contradiction:

Length of moving objectVSStability of the object's composition

Solution Approach 1:

The patent incorporates preliminary positioning features such as pre-placed clips at specific intervals along the leash and a structured attachment system that anticipates the need to prevent sliding. These features are built into the design beforehand, allowing the bag to be securely positioned at the optimal distance from the hand while preventing unwanted movement or falling off during use.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If both hands are committed to holding the leash and carrying waste, then the user can control the dog, but the user cannot handle other objects like keys, phone, or mace

Engineering Contradiction:

Improvecontrol of dogVSAvoidability to handle other objects

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent creates a multi-functional attachment system where the bag structure serves multiple purposes: it securely holds waste bags, provides attachment points for additional items like keys or phones through integrated loops or pockets, and maintains leash control. This universal design allows the single apparatus to handle various objects and functions simultaneously, resolving the contradiction between controlling the dog and accessing other items.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A carrying apparatus for containing objects such as animal waste attachable to a line, such as an animal leash or a climbing rope. Embodiments of the carrying apparatus can include a bag, a strap, one or more loops, and can coordinate with a line. The carrying apparatus preferably also includes a secondary container, which itself can include an outlet formed on a sidewall thereof.
