Retractable Leg-Limiter Harness for Pet Movement Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet harnesses with leads struggle to effectively control a pet's behavior due to the high traction force exerted on the user when the pet rushes around, leading to poor control and potential dragging.
Innovation Solution
A pet harness with a harness body, leg limiters, and a driving device that includes a binding rope, where the driving device retracts or extends the binding rope to regulate the pet's leg movement, enhancing behavior management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lead is used to control the pet's movement, then the user can guide the pet, but the lead exerts greater traction force on the user when the pet rushes around, causing the pet to drag the user
Solution Approach 1:
The invention divides the control function into two independent parts: a lead for guiding the pet's overall direction and leg limiters for controlling specific leg movements. This segmentation allows the lead to maintain light tension while the leg limiters handle the forceful restraint, resolving the contradiction between control effectiveness and excessive traction force on the user.
Solution Approach 2:
The leg limiters act as intermediary devices between the pet's legs and the user's control. By placing mechanical constraints directly on the legs through the limiters and binding ropes, the system mediates the control force away from the lead, reducing the traction force transmitted to the user while maintaining effective behavior control.
2Ease of operation
If the binding rope is retracted to limit pet movement, then the leg limiter restricts pet movement effectively, but the driving device requires mechanical components such as motors and rolling members
Solution Approach 1:
The binding rope is designed to be retractable through the driving device, which automatically winds and unwinds the rope based on the pet's movement. This self-service mechanism reduces the need for continuous manual adjustment by the user, allowing the system to maintain effective behavior control while minimizing the complexity of manual operation.
Solution Approach 2:
The driving device incorporates dynamic components such as rolling members that can rotate to retract or extend the binding rope as needed. This dynamic adjustment capability allows the system to adapt to the pet's movements in real-time, providing effective control while using simple mechanical motion rather than complex control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The harness effectively limits the pet's movement range by tightening leg limiters when needed, improving control over the pet's behavior and reducing the risk of the pet dragging the user.
Implementation Method 1
a motor provided in the receiving cavity and a rolling member sleeved on an output shaft of the motor and configured to rotate forward or reverse under the drive of the motor

AI summary
Disclosed is a pet harness. The pet harness includes a harness body, a leg limiter, a driving device and a binding rope. The harness body includes a shoulder strap portion and a waistband portion. The leg limiter is annular and is sleeved on legs of the pet. The driving device is provided on the shoulder strap portion. One end of the binding rope is connected to the leg limiter, and the other end of the binding rope is connected to the driving device along an extension direction of the waistband portion. The driving device is configured to retract the binding rope to lead the leg limiter for restricting a pet movement, or to lengthen the binding rope to release the leg limiter for allowing the pet to move freely.
