Retractable Pet Leash With Integrated Waste Bag Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet leashes require one hand for control, leaving no free hand for carrying essential items like waste bags or ball throwers, and manual waste collection is cumbersome and potentially messy.
Innovation Solution
A retractable leash system integrated with a bag dispenser and storage container, allowing for hands-free waste bag dispensing and storage, along with an attachable ball thrower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional leash is used to control the pet, then the pet can be restrained and controlled, but the user's hands are occupied and cannot carry other essential items like waste bags or ball throwers
Solution Approach 1:
The patent combines multiple functions (leash control, waste bag dispensing, waste storage, and ball throwing) into a single integrated device. The housing contains both the retractable leash mechanism and the waste bag dispenser, with the storage container attachable to the housing, creating a multi-functional system that eliminates the need to carry separate items.
Solution Approach 2:
The leash device is designed to perform multiple functions: restraining the pet via the retractable leash, dispensing waste bags through the dispenser mechanism, storing waste in the attachable container, and throwing balls using the integrated ball thrower. This universal design allows one device to replace multiple separate items.
2Reliability
If manual waste collection is performed, then waste can be collected in bags, but the process is cumbersome and requires manual handling that may cause mess or contamination
Solution Approach 1:
The waste bag dispenser is designed to automatically provide bags to the user without requiring manual retrieval from a container. The ball thrower mechanism autonomously propels balls without requiring the user to manually throw them repeatedly, reducing physical strain and potential contamination.
3Adaptability or versatility
If multiple separate items (leash, waste bags, storage container, ball thrower) are carried, then all functions are available, but the device complexity and number of items to manage increases
Solution Approach 1:
The patent integrates the leash mechanism, waste bag dispenser, and storage container attachment points into a single unified housing structure. This merging of previously separate items into one device reduces the number of individual items the user must carry and manage while maintaining all necessary functions.

AI summary
An animal leash system with a storage container (112) and a bag container (120). The system includes a housing (12) that encloses a leash retracting mechanism (14) configured to control movement of a leash extending thereout. The bag container (120) includes an open end (124) configured to receive a bag container cap (126) or an end (134) of a ball thrower device (132). The storage container (112) includes a container cap (116) defining a recess (118) configured to threadably receive a threaded post (128) of the bag container cap (126). The system provides a single unit that includes the advantages of a retractable pet leash with the convenience of having bags ready for use to collect pet waste along with a storage container for disposing of waste filled bags.
