Pet Leash with Carabiner and Loop Handle for Quick Fastening
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
