Extendable Animal Leash Quick Release for Emergency Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extendable animal leashes pose safety risks in emergency situations, such as when a pet runs away, as the attached housing can cause injury, entanglement, or damage, and the owner may struggle to quickly release the leash.
Innovation Solution
An extendable animal leash with a quick release mechanism, featuring a button that disconnects the leash from the housing, using a pull-pin or magnetic mechanism, allowing immediate separation in emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional extendable leash mechanism is used, then the leash can extend and retract automatically, but the leash cannot be quickly released from the housing in emergency situations
Solution Approach 1:
The leash system is divided into separable components: the leash assembly and the housing. The quick release button enables the leash to be disconnected from the housing, transforming a monolithic structure into separable parts that can be quickly separated in emergencies.
Solution Approach 2:
The quick release button extracts the leash from its constrained state within the housing. By pressing the button, the leash is rapidly extracted or separated from the housing assembly, enabling emergency release without manual manipulation of the entire mechanism.
2Object-affected harmful factors
If the leash is securely attached to the housing, then control is maintained, but the attached housing can cause injury, entanglement, or damage in emergency situations
Solution Approach 1:
The attachment strength of the leash to the housing is made dynamic rather than static. The quick release button allows the attachment strength to be rapidly reduced from a secure locked state to a separated state, enabling the system to adapt between maintaining control during normal use and preventing harm during emergencies.
Solution Approach 2:
The quick release button provides a pre-prepared safety mechanism that cushions against potential harm. By having the release capability built into the design beforehand, the system prevents injury, entanglement, or damage before these harmful effects can occur in emergency situations.
3Ease of operation
If a magnetic pull-pin mechanism is used, then the release can be triggered by magnetic force, but the mechanism complexity increases
Solution Approach 1:
The traditional mechanical pull-pin release mechanism is substituted with a magnetic field-based system. Instead of requiring manual manipulation of mechanical components, a magnetic field can act on the magnetic pull-pin to trigger the release, replacing complex mechanical actuation with a simpler magnetic interaction.
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 quick release mechanism ensures the pet's safety by detaching the leash instantly, preventing harm to the pet and owner, and maintaining control during unexpected events.
Implementation Method 1
the mechanism includes a magnetic pull-pin that is configured to move when a magnetic force is applied to the magnetic pull-pin
Implementation Method 2
pushing or engaging the quick leash release button causes an electrical circuit to apply a current to an electrical coil, thereby causing a magnetic field to be applied to the magnetic pull-in

AI summary
An extendable animal leash incorporates an advanced quick release functionality within its design. Housed in an ergonomic casing for comfortable handling, the leash can be swiftly disconnected using a quick leash release button. This button triggers a mechanism involving either a pull-pin connected to a cord, string, or cable, or a magnetic pull-pin activated by a magnetic force. Upon engagement, the quick release mechanism allows the leash to detach from the housing, providing immediate separation. The leash itself, made from durable materials like nylon, polyester, or leather, is retracted by a spring recoil mechanism. Additionally, the housing features a spool locking button for setting the leash length and ensuring controlled retraction. Constructed from lightweight and durable materials such as plastic or aluminum, the housing is designed for easy opening, facilitating maintenance and reassembly of the quick release components.
