Solution Overview

Problem

There is a need for a dog collar with a low-profile retractable leash that is easily attachable and detachable, providing short-range control over the dog without the bulk of traditional leashes, especially in situations where a regular leash is not available.

Innovation Solution

A dog collar with a low-profile retractable leash attachment that includes a sleeve with an elastomeric cord, secured by a snap hook to a D-ring, allowing the cord to extend and retract for temporary control, and detachable from the collar for easy replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If a traditional spring-loaded retractable leash is used, then the dog can be controlled over long distances, but the leash becomes bulky and complex

Engineering Contradiction:
Improveleash lengthVSAvoidleash mechanism complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent extracts only the essential retractable leash function from the traditional spring-loaded mechanism, removing the bulky spring assembly while retaining the elastomeric cord's elastic retraction capability. This creates a simplified leash that provides sufficient control for short distances without the complexity of full retractable mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a simple elastomeric cord instead of a durable, complex spring-loaded mechanism. The elastomeric cord is inexpensive, lightweight, and sufficient for temporary use, embodying the principle of using simple, disposable-like components for short-term needs rather than investing in permanent, complex systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If a long leash is carried for normal walks, then the dog can be controlled effectively, but the leash is not available for immediate use in emergencies or short trips

Engineering Contradiction:
Improveleash availabilityVSAvoidtime to retrieve leash
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent attaches the elastomeric cord leash to the dog collar in advance, so it is immediately available for use in emergencies or short trips without requiring the owner to retrieve it from elsewhere. The preliminary attachment ensures the leash is ready when needed, eliminating time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a multi-functional collar system where the same collar structure serves both as a regular collar and as an attachment point for the elastomeric leash. This universal design allows the collar to fulfill multiple functions - normal collar use and emergency leash attachment - without requiring separate items.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a visible leash is attached to the collar, then the dog can be controlled, but the leash creates entanglement and snagging risks

Engineering Contradiction:
Improvedog controlVSAvoidentanglement and snagging
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses a thin, flexible elastomeric cord instead of a rigid or bulky leash. The elastomeric material is smooth and thin-profiled, reducing the likelihood of entanglement and snagging on obstacles while still providing effective control. The flexible nature of the material allows it to move smoothly without creating harmful interactions with the environment.

Inventive Principle:
Principle #30Flexible shells and thin films

4Adaptability or versatility

If a permanent leash attachment is made to the collar, then the leash is always available, but it cannot be easily removed for replacement

Engineering Contradiction:
Improveleash availabilityVSAvoidattachment and detachment ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent creates a dynamic attachment system using a snap hook that can be easily engaged and disengaged. The snap hook provides a secure connection when attached, ensuring the leash is always available, but can be quickly removed when replacement is needed. This dynamic design balances permanent availability with easy replaceability.

Inventive Principle:
Principle #15Dynamics

AI summary

A dog collar with detachable and retractable leash attachment. The leash attachment includes a leash in the form of an elastomeric cord is provided inside a sleeve that may be temporarily engaged around the dog collar. One end of the leash pivotally attached to the collar using a clip, and a handle is provided at the other end. Grasping and pulling the handle releases the sleeve from the collar and stretches the elastomeric cord, providing a short leash for a pet owner to control and direct a dog over short distances. The leash attachment may include an engagement surface that is operable to temporarily attach to a complementary surface on the exterior of the collar.
