Spring-Loaded Hinge Buckle for Secure Single-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal collar and leash buckles are either cumbersome to operate, leading to inconvenience and potential irritation for animals, or too easy to open accidentally, causing the animal to be set free.
Innovation Solution
A buckle design featuring a clasp with a spring-loaded hinge that allows for easy single-handed operation between open and closed positions, ensuring secure closure without user intervention, comprising a first and second clasp member that contact each other in the closed position and rotate to open with user pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buckle is made secure and difficult to open, then the reliability of closure is improved, but the ease of operation deteriorates
Solution Approach 1:
The buckle employs a dynamic hinge mechanism that transitions between a locked closed position and an open position. The hinge allows controlled movement when force is applied to the lever, enabling easy opening while maintaining secure closure when at rest. This dynamic behavior resolves the contradiction by making the buckle both secure during wear and easily operable when needed.
Solution Approach 2:
The lever acts as an intermediary element between the user's hand and the clasp mechanism. By applying force to the lever rather than directly manipulating the clasp, the user can easily open the buckle with minimal effort. The lever amplifies the user's input force, making the opening action simple while the hinge maintains secure closure, thus resolving the ease of operation versus reliability contradiction.
2Ease of operation
If the buckle is made easy to open and close, then the ease of operation is improved, but the reliability of closure deteriorates due to accidental opening
Solution Approach 1:
The hinge mechanism provides a dynamic solution where the buckle is easily openable when force is applied to the lever, but maintains secure closure during normal wear. The controlled movement capability allows easy operation while the locked position ensures reliability, preventing accidental opening without requiring excessive force.
Solution Approach 2:
The lever serves as an intermediary that requires deliberate user action to open the buckle. The hinge mechanism translates the lever's movement into controlled clasp separation, ensuring that only intentional pressure on the lever can open the buckle, thus maintaining closure security while enabling easy operation.
3Reliability
If the buckle requires two-handed operation, then the reliability of closure is improved, but the ease of operation deteriorates
Solution Approach 1:
The lever acts as an intermediary that enables single-handed operation. By designing the hinge and clasp mechanism to respond to force applied on one side, the buckle can be opened and closed using only one hand. The lever amplifies the single-handed input force sufficiently to operate the clasp, maintaining closure security while enabling convenient single-handed use.
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 convenient and efficient attachment and removal of collars and leashes, preventing animal irritation and dirt/odor buildup while ensuring the buckle remains closed without accidental opening.
Implementation Method 1
The hinge may further be spring-loaded to provide for single-handed operation. When the user releases the pressure on the second clasp member, the spring-loaded hinge rotates the second clasp member back to its original position
Implementation Method 2
When the user exerts and maintains pressure on the second clasp member, the second clasp member acts as a lever and rotates on the hinge

AI summary
Disclosed is a buckle for an animal collar and/or leash that is easy to open and close, but at the same time does not open without user intervention. Illustratively, the inventive apparatus comprises a buckle that includes a first clasp member and a second clasp member that form a clasp. Pressure is applied and maintained at the second clasp member to transition the clasp from a closed position to an open position, wherein the second clasp member rotates around a hinge. As the buckle is easy to open and close, the user can conveniently attach the collar or leash to the animal and remove the collar or leash from the animal when it is no longer needed, thus preventing irritation of the animal and build-up of dirt and/or odors. The single-handed operation allows the user to attach and remove the collar or leash efficiently and with minimal effort.
