Pet Waste Bag Roll Color Coding for Low-Supply Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pet owners often run out of waste disposal bags while walking their dogs due to difficulty in tracking the remaining supply, especially when dogs defecate multiple times during a walk.
Innovation Solution
Color-coded pet waste collection bags with distinct color changes near the end of the roll to visually alert the user of low supply, using one or more alerting colors to indicate when a new roll is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pet owners carry a roll of waste disposal bags, then they are prepared for multiple defecation events during a walk, but they may run out of bags without realizing it
Solution Approach 1:
The patent applies color changes to the bags themselves, where bags near the end of the roll are colored differently (e.g., red or yellow) compared to the majority of bags. This visual differentiation allows pet owners to immediately perceive the bag supply status without needing to count or track the number of bags remaining in the roll.
2Loss of information
If pet owners track the number of bags remaining in the dispenser, then they can know when to replace the roll, but this becomes inconvenient and time-consuming during walks
Solution Approach 1:
Instead of requiring pet owners to count or track the number of bags, the patent uses color coding to provide immediate visual feedback. Bags near the end of the roll are colored distinctly (red/yellow) while the majority remain the original color, allowing owners to assess supply status at a glance without interrupting their walk or mental tracking.
Solution Approach 2:
The bag roll provides self-service information about its own supply status through the color-coded bags. The system automatically indicates when replacement is needed without requiring the owner to actively monitor or calculate the remaining bag count, making the information accessible passively during the walk.

AI summary
Pet waste collection bags, which can visually remind a user of the low supply of bags, are provided. The invention utilizes different color(s) for the last few bags in a roll of pet waste collection bags to notify the user when the last few bags are left in the pet waste collection bag dispenser. When the user sees the bag color change, they know it is time to insert a new roll of pet waste collection bags into the bag dispenser.
