Integrated Retractable Dog Harness for Immediate Leash Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog leashes require frequent attachment and detachment, which can be inconvenient and stressful for owners during off-leash adventures, especially when sudden leash use is necessary.
Innovation Solution
An integrated retractable leash dog harness device with a spring-loaded reel that stores the leash within a harness body, allowing easy access and storage when not in use, featuring adjustable straps and a handle for leash extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate leash is carried in a bag or pocket, then the leash is portable, but it requires frequent attachment and detachment which is inconvenient and stressful
Solution Approach 1:
The patent combines the leash and harness into a single integrated device. The retractable leash is built directly into the harness body, eliminating the need to separately carry and attach a leash. The leash automatically retracts into the harness when not in use, providing both portability and immediate accessibility.
Solution Approach 2:
The leash is pre-positioned within the harness body in a retracted state. The spring-loaded mechanism keeps the leash ready for immediate deployment, eliminating the need to retrieve and attach it at the moment of need. The leash is already in place, prepared for quick extension when required.
2Ease of operation
If a retractable leash is integrated into the harness, then the leash is easily accessible and storable, but the device complexity increases
Solution Approach 1:
The retractable leash mechanism is nested within the harness body. The leash cord is contained inside the harness housing, with the spring-loaded reel mechanism integrated into the existing harness structure. This nesting approach provides easy access and storage functionality while minimizing the increase in external device complexity.
Solution Approach 2:
The harness body serves multiple functions: it provides the structural support for the dog, contains the retractable leash mechanism, and houses the spring-loaded reel system. By making the harness multi-functional, the patent reduces the need for separate components, thereby managing device complexity while enhancing ease of operation.
3Ease of operation
If the leash is stored within the harness body, then portability is improved, but the housing volume required increases
Solution Approach 1:
The leash mechanism is nested within the existing harness body structure. Rather than adding external storage compartments, the retractable leash system is integrated into the hollow interior spaces of the harness, utilizing the existing volume efficiently. The spring-loaded reel and leash cord are contained within the harness housing without significantly increasing its external dimensions.
Solution Approach 2:
The leash transitions from a static separate component to a dynamic integrated system. The retractable leash can extend and retract as needed, allowing the harness to maintain a compact form when the leash is retracted while providing full leash functionality when extended. This dynamic capability improves portability without requiring permanent increases in housing volume.

AI summary
An integrated retractable leash dog harness device is provided. The device is comprised of a harness body that is designed to fit around the torso of an animal and includes primary and secondary adjustable straps for securing the device around the neck and torso of the animal. The body further comprises a housing containing a spring-loaded reel for retracting a leash into the housing when not in use. The leash can be extended via a handle that may include attachment points for accessories like waste bag dispensers. In some embodiments, the body or housing may include pockets for storing waste bags and a clip may be used to secure the leash or create a secondary handle.
