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 other items or engage in activities while restraining their pets.

Innovation Solution

A multifunctional pet traction rope with an adjustable loop, 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

VSEngineering 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

Engineering Contradiction:
Improveadaptability to different usage scenariosVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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 the traction rope to adapt to different usage scenarios such as hand-holding, shoulder-carrying, or securing to stationary objects, while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by designing the adjustment buckle with multiple threading holes arranged in different patterns (rectangular, square, pentagonal). This allows the same basic structure to serve multiple functions: adjusting loop size, changing rope configuration, and adapting to various restraint scenarios, making the traction rope universally applicable to different user needs and pet sizes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 other items

Engineering Contradiction:
Improveease of operation when carrying itemsVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The adjustment buckle enables dynamic adaptation of the loop size based on operational needs. When users need to carry items, they can enlarge the loop to fit over their hand or arm, freeing both hands for carrying. The sliding mechanism allows quick adjustment without tools, maintaining ease of operation while adding minimal structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of loop size from fixed to variable. By providing multiple threading holes at different positions on the adjustment buckle, the effective loop length can be changed by selecting different hole combinations, allowing the rope to accommodate both hand-holding and shoulder-carrying scenarios without requiring multiple different ropes.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a fixed loop design is used, then the device is simple, but the versatility for different pet sizes and user needs is limited

Engineering Contradiction:
Improveversatility for different pet sizesVSAvoidadjustment buckle complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment buckle serves as a universal component that accommodates different pet sizes and user needs through its multiple threading holes. The same buckle structure works for small and large pets, different rope types (nylon, woven strap, metal), and various restraint methods, eliminating the need for multiple specialized ropes while adding minimal complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adjustment buckle divides the rope into adjustable segments by providing multiple threading holes. This segmentation allows independent adjustment of loop size and rope configuration, enabling the same basic rope structure to be customized for different pet sizes, strength levels, and usage scenarios without redesigning the entire rope.

Inventive Principle:
Principle #1Segmentation

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.
