Adjustable Pet Traction Rope Loop for Hands-Free Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet traction ropes have a fixed, non-adjustable loop size, which limits their applicability and can cause inconvenience when users need to carry items or engage in other activities while restraining their pets.
Innovation Solution
A multifunctional pet traction rope with an adjustable loop is designed, featuring a rope body, a hook for attachment to a pet's collar or harness, and an adjustment buckle with threading holes that allow the rope body to form limiting sections, enabling the loop size to be adjusted according to user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed loop size is used in the traction rope, then the structure is simple and easy to manufacture, but the adaptability to different usage scenarios is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed loop structure into an adjustable loop structure. The loop size can be dynamically changed by sliding the rope end through the adjustment buckle, allowing users to adapt the loop size to different hand sizes, carrying needs, and usage scenarios. This resolves the contradiction by making the structure adaptable without requiring multiple separate products.
Solution Approach 2:
The adjustment buckle mechanism provides universal applicability by enabling the same traction rope to serve multiple functions: holding in hand, carrying over shoulder, or securing to objects. The ability to adjust loop size makes the product universally suitable for different users and different usage scenarios, eliminating the need for multiple fixed-size ropes.
2Ease of operation
If the loop size is fixed to fit only the user's hand, then the manufacturing is simple, but the ease of operation is reduced when users need to carry items
Solution Approach 1:
The dynamic adjustment mechanism allows users to easily modify the loop size according to their carrying needs. When carrying items, users can enlarge the loop to accommodate larger hands or different holding positions. The sliding mechanism provides easy operation without requiring tools or complex procedures.
Solution Approach 2:
The adjustment buckle is designed for self-service operation. Users can independently adjust the loop size by sliding the rope end through the buckle without needing assistance or special tools. The friction-based holding mechanism maintains the adjusted position automatically once set.
3Adaptability or versatility
If a fixed loop is used, then the device complexity is low, but the versatility for different activities is limited
Solution Approach 1:
The adjustment buckle divides the rope into adjustable segments, allowing different loop sizes to be created from the same rope body. This segmentation enables versatility for different activities (walking, running, carrying items) while maintaining a single integrated manufacturing process for the rope and buckle components.

AI summary
A multifunctional pet traction rope is provided, comprising a rope body, a hook fixed to one end of the rope body, and an adjustment buckle; at least four threading holes are opened on the adjustment buckle, arranged in at least two rows; the rope body passes through two of these threading holes, forming a first limiting section between the two threading holes; the end of the rope body, passes through two of the remaining threading holes, forming a second limiting section located between the first limiting section and the adjustment buckle; a loop is formed by segments of the rope body between the first section and the second limiting section; the end of the rope body adjacent to the hook slides relative to the adjustment buckle, allowing a position of the first limiting section on the rope body to change and thereby adjust a size of the loop.
