Solution Overview

Problem

Existing pet leashes fail to maintain multiple pets untangled during walks, often becoming crossed or tangled, and lack individual control, leading to wear and tear issues.

Innovation Solution

A pet leash assembly featuring a track with sliding connectors and handles, allowing for adjustable length and separate control of each pet, with optional stoppers and length adjustors to prevent tangling and wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If retractable leashes are used to control leash length, then the handler can adjust the leash length, but the internal components and mechanisms are prone to wear and tear

Engineering Contradiction:

Improveleash length controlVSAvoidmechanism durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The leash is divided into multiple segments with individual connectors for each pet, allowing independent adjustment and control of leash length for each pet without affecting the overall system reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The leash incorporates dynamic adjustment mechanisms that allow the handler to change leash length on demand, providing adaptability while distributing mechanical stress across multiple connection points rather than a single mechanism

Inventive Principle:

Principle #15Dynamics

2Productivity

If multiple pets are tethered using one fixed length leash, then the handler can walk multiple pets, but the pets can tangle and pull at one another without individual control

Engineering Contradiction:

Improvemulti-pet walking capabilityVSAvoidindividual pet control

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The leash system is segmented into multiple independent sections, each with its own connector and adjustable length, allowing the handler to control each pet individually while maintaining the ability to walk multiple pets simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The leash provides more control than a single fixed-length leash by allowing independent adjustment of each pet's leash section, enabling the handler to apply partial control to specific pets that need it while maintaining productivity

Inventive Principle:

Principle #16Partial or excessive action

3Device complexity

If basic fixed length leashes are used, then the structure is simple, but the leashes become crossed or tangled during walking

Engineering Contradiction:

Improveleash structureVSAvoidtangle prevention

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The leash is divided into multiple segments with individual connectors that can move independently along the track, preventing tangles while maintaining relatively simple construction

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connectors are designed to slide freely along the track, allowing dynamic adjustment to prevent crossing and tangling during pet movement, while the overall structure remains simple and straightforward

Inventive Principle:

Principle #15Dynamics
