Remote Solenoid Quick Release for Leash Snagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collar and leash combinations for police, military, or detection dogs require manual release mechanisms that can be time-consuming and risk snagging, potentially allowing perpetrators to escape during exigent situations.
Innovation Solution
A remotely operable quick release mechanism with a push-button activation using a solenoid or gear motor, integrated into a universal quick release system that automatically detaches the leash from the collar, allowing for immediate release of the dog without manual retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual spring returned clasp is used to connect the leash to the collar, then the connection is secure during normal operation, but the release process requires manual retrieval of the dog to within arms length, resulting in time loss
Solution Approach 1:
The patent replaces the manual mechanical spring returned clasp with an automated solenoid actuated release mechanism. The solenoid receives remote signals to automatically actuate the release, eliminating the need for manual retrieval and arms-length operation, thus resolving the time loss while maintaining connection security during normal operation
Solution Approach 2:
The patent introduces a remote control system as an intermediary between the handler and the release mechanism. The remote allows the handler to trigger the solenoid actuated release from a distance, eliminating the need to physically retrieve the dog to within arms length, thereby resolving the time loss issue while maintaining secure connection during operation
2Speed
If the handler merely releases the manual grip on the leash to release the canine, then the release is quick, but it poses a snag risk that may prevent the canine from reaching its destination
Solution Approach 1:
The patent replaces manual grip release with an automated solenoid actuated release mechanism that detaches the collar from the leash through controlled mechanical action. This eliminates the snag risk associated with manual grip release while maintaining quick release capability, as the solenoid provides precise and clean detachment without requiring the handler to physically manipulate the leash
3Extent of automation
If a remotely operable quick release mechanism with solenoid or gear motor is used, then the release is immediate and automated, but the device complexity increases
Solution Approach 1:
The patent extracts the complex solenoid or gear motor actuation mechanism from the simple manual clasp design to achieve automated remote operation. This extraction enables immediate automated release while accepting the necessary increase in device complexity, as the remote-operable quick release mechanism requires additional components (solenoid/gear motor, remote control system, piston, slider) to function automatically
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
Enables rapid and secure detachment of the dog from the leash with a single button press, reducing the risk of snagging and allowing the dog to reach its destination quickly, enhancing handler safety and operational efficiency.
Implementation Method 1
The release mechanism may include a push pull piston solenoid or a gear motor.
Implementation Method 2
The release mechanism may include a push pull piston solenoid or a gear motor.

AI summary
A remotely operable quick release is provided that may be placed between a collar or harness to release an animal or object. A nylon strap with a D-ring on one end attaches to a holding device. On the other end supports a flip latch attached to a harness. The release mechanism on the top of the strap includes a push pull piston solenoid. A metal slider urged by the solenoid holds prevents the flip latch from releasing. When the solenoid is activated the piston and slider pull back to release the flip latch. The solenoid is operated with a wireless remote control receiver transmitter key fob. When the button is push it activates the solenoid which pulls the piston and slider back to free the flip latch. Resetting the flip latch is accomplished by pushing down on the slider and allowing the piston to slide forward to re-engage.
