Hands-free Pet Walker Bag with Double Besom Leash Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with disabilities, such as multiple sclerosis, arthritis, and limited mobility face challenges in securely walking pets without tangling or detaching leashes during pet walks, as existing solutions do not provide a hands-free and secure leash management system.
Innovation Solution
A human-wearable bag device with a functional pocket containing a double besom opening for securing a retractable leash system, allowing the leash to be threaded from inside the bag to a pet harness outside, enabling hands-free pet walking while accommodating various leash sizes and securing the leash within the bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional leash is carried outside the bag during pet walking, then the leash is easily accessible for quick attachment, but the leash may become tangled or inadvertently detached from the bag
Solution Approach 1:
The leash is stored within a dedicated functional pocket nested inside the bag, creating a nested structure where the leash resides securely within the bag's interior. The double besom opening allows the leash to pass through the bag wall while remaining contained, preventing tangling and inadvertent detachment while maintaining secure storage.
Solution Approach 2:
The double besom opening acts as an intermediary element between the interior functional pocket and the exterior environment. This intermediate structure allows the leash to be threaded from inside the bag to the pet harness outside while maintaining secure containment, solving both the security and accessibility requirements.
2Ease of operation
If the functional pocket opening is made larger to accommodate various leash sizes, then leash insertion and removal is easier, but the pocket becomes less secure and more visible from the outside
Solution Approach 1:
The opening is segmented into a double besom structure with two distinct openings positioned close together. This segmentation allows the leash to be threaded through both openings in sequence, providing ease of insertion and removal while maintaining a relatively small overall footprint that preserves pocket security and minimizes external visibility.
Solution Approach 2:
The double besom opening utilizes a three-dimensional configuration where two openings are positioned at different locations on the bag wall. This dimensional arrangement allows leashes of varying thicknesses to be accommodated while maintaining a compact opening structure that does not compromise pocket security or excessive visibility.
3Reliability
If the functional pocket is sealed completely to maximize security, then the leash is fully protected from tangling, but the leash cannot be accessed or threaded to the pet outside
Solution Approach 1:
The leash is extracted from the fully sealed pocket environment through the double besom opening to the exterior. This extraction allows the leash to be accessed and attached to the pet harness outside while the majority of the functional pocket remains sealed and secure, maintaining both containment and access capabilities.
Solution Approach 2:
The leash is pre-positioned within the functional pocket in a secured state before use. The double besom opening is designed to allow the leash to be pulled through in a controlled manner, maintaining preliminary security while enabling access when needed. The pocket can be resealed after use to restore full containment.

AI summary
The present disclosure relates to bag device worn on the shoulder or across the body that contains a pocket capable of securing a retractable leash and a double besom opening to allow threading of leash tether from inside the pocket to a pet harness outside the bag. This allows for walking a pet hands-free without the risk of the leash being inadvertently tangling or detaching from the bag. The bag is particularly useful for walking pets by individuals with physical impairments.
