Double Leash Dog Collar with Snug Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog collars and leashes often cause discomfort and injury to both dogs and their walkers due to excessive tug force when dogs pull or have stability issues during walks.
Innovation Solution
A dog collar and leash combination featuring a double leash with a handle and a 'snug & release' mechanism, providing symmetrical support and control, reducing torque on the walker and allowing the dog to self-regulate pulling, along with a wide, comfortable collar to minimize discomfort and prevent escape attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single leash is used to control a pulling dog, then the dog walker can maintain basic control, but excessive tug force is exerted on the walker's shoulder, neck, arm and back causing injuries
Solution Approach 1:
The single leash is divided into two separate leashes that attach to opposite sides of the dog's neck. This segmentation distributes the tug force across two attachment points, reducing the torque and strain on the walker's body while maintaining control effectiveness through symmetrical pressure distribution on the dog's neck.
Solution Approach 2:
The double leash configuration creates a counterbalancing effect where the two leashes work in opposition to each other, neutralizing excessive torque forces. When the dog pulls, the symmetrical arrangement ensures forces are distributed evenly, preventing the cumulative strain that occurs with single-leash configurations.
2Object-affected harmful factors
If a narrow collar is used to control a dog, then the collar can be easily fitted, but it causes pain and discomfort to the dog's throat and neck
Solution Approach 1:
The collar is divided into two separate halves that can be independently adjusted and fitted around the dog's neck. This segmentation allows each half to be optimized for comfort with adequate width and padding, while the overall structure remains manageable and easy to fit through the split design.
Solution Approach 2:
Different portions of the collar have different widths and properties - the inner surface contacting the dog's neck is wide and padded for comfort, while the outer structural portions can be narrower for ease of handling and fitting. This local differentiation resolves the contradiction between comfort and ease of fitting.
3Reliability
If a dog pulls excessively on the leash, then the dog may escape or injure itself, but the dog walker loses control and experiences injuries
Solution Approach 1:
The snug & release mechanism provides automatic feedback - when the dog pulls, the collar cinches snugly to provide correction and control, and when the dog releases, the collar automatically returns to a comfortable state. This continuous feedback loop maintains control reliability while preventing injuries through automatic pressure regulation.
Solution Approach 2:
The collar's snug & release mechanism allows the dog to self-regulate its own collar tension through pulling and releasing actions, eliminating the need for the walker to continuously manually adjust tension. The system serves itself by automatically responding to the dog's behavior, maintaining control while preventing excessive force.
4Ease of operation
If excessive tug force is applied to control a pulling dog, then the walker can maintain control, but it causes injuries and requires therapy or surgeries
Solution Approach 1:
By segmenting the control system into a double leash configuration, the force distribution changes from concentrated torque on single attachment points to distributed pressure across two symmetrical attachment points. This segmentation maintains control ability while reducing the magnitude of force transmitted to the walker's body, preventing injuries.
Solution Approach 2:
The wide, padded collar design provides beforehand cushioning between the leash forces and the dog's neck, preventing concentrated pressure points that could cause injury. The padding absorbs and distributes forces before they reach the dog's vulnerable areas, while the symmetrical double leash arrangement cushions the walker from excessive torque.
