Solution Overview

Problem

Existing pet leashes require time-consuming winding and knot-tying processes to secure them to external objects, making it inconvenient for owners to temporarily restrain their pets while keeping their hands free or entering pet-restricted areas.

Innovation Solution

A pet leash design featuring a front leash, rear leash, carabiner, loop-shaped handle, size adjusting part, and trigger hook, allowing for quick and easy fastening to external objects by forming a fastening ring that can be secured to a carabiner, enabling rapid attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pet leash is secured to a fixed object by winding and tying with a knot, then the pet leash is securely fastened to the fixed object, but the process costs time and is inconvenient for the owner

Engineering Contradiction:
Improvesecuring reliabilityVSAvoidfastening time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The pet leash is divided into multiple segments: a front leash portion, a rear leash portion, and a loop-shaped handle portion. The carabiner is attached to the front leash second end and can independently engage with the loop-shaped handle, separating the fastening function from the leash structure. This segmentation allows quick attachment without winding or knot-tying while maintaining secure fastening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carabiner serves as an intermediary device between the leash system and the loop-shaped handle. Instead of directly tying the leash to the fixed object, the carabiner mediates the connection by clipping onto the loop-shaped handle, which is then attached to the fixed object. This intermediary mechanism enables rapid fastening and unfastening while ensuring reliable securing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the owner needs hands free or wants to enter pet-restricted areas, then the owner can temporarily fasten the pet leash to a fixed object, but the traditional winding and tying process is inconvenient

Engineering Contradiction:
Improvefastening convenienceVSAvoidfastening time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The loop-shaped handle is pre-formed and permanently attached to the rear leash first end, creating a ready-to-use fastening interface. The carabiner is pre-attached to the front leash second end. This preliminary preparation eliminates the need for on-site winding or knot-tying, allowing the owner to quickly clip the carabiner onto the loop-shaped handle and attach to any fixed object, greatly improving ease of operation and reducing time loss.

Inventive Principle:
Principle #10Preliminary action
