Solution Overview

Problem

Standard two-part buckle systems are difficult to release quickly while moving, and cord-based quick-release mechanisms can inadvertently release in restricted environments due to catching on objects.

Innovation Solution

A quick-release buckle assembly with a male portion that includes a pivotable lever and engaging element, allowing the locking legs to be moved inward for release without the need for cord pulling, enabling easy disengagement with minimal finger movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a cord pull mechanism is used for quick release, then the buckle can be disengaged quickly, but it may inadvertently release when the cord catches on objects in restricted environments

Engineering Contradiction:
Improvequick release capabilityVSAvoidaccidental disengagement
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent removes the cord pull mechanism from the buckle system entirely, extracting the problematic external release method while retaining quick release capability through the integrated lever mechanism that operates without external cords or pulls

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lever mechanism is integrated directly into the male buckle portion, allowing the user to release the buckle through a self-contained mechanical action on the buckle itself rather than relying on an external cord that may interact with environmental objects

Inventive Principle:
Principle #25Self-service

2Device complexity

If traditional side-release buckles are used, then the structure is simple, but the buckle cannot be easily released while the user is moving

Engineering Contradiction:
Improvebuckle structureVSAvoidrelease speed while moving
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent introduces a pivotable lever that can be quickly actuated through a simple lifting motion, transforming the static squeezing action into a dynamic pivoting motion that is much easier to perform while moving or in restricted positions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The release mechanism changes from a horizontal squeezing motion (traditional side-release) to a vertical lifting motion of the lever, utilizing a different dimensional approach that is more suitable for quick release while moving

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Facilitates rapid and secure release of the buckle in tight spaces without accidental disengagement, providing a reliable and efficient quick-release mechanism for articles like tactical vests.

Implementation Method 1

The means for moving the locking leg toward the central leg can comprise a lever pivotably connected at one end to the male portion

Methodology Applied
Scientific EffectLever: Lever

Implementation Method 2

The male portion has an engaging element connected to a free end of the locking legs and contacting the tongue, so that lifting the free end of the lever causes the tongue to push the engaging element toward the base of the male portion

Methodology Applied
Scientific EffectMechanical Force: Mechanical Force

AI summary

A quick release buckle assembly has a male portion and a female portion. The female portion has a hollow body and at least one locking slot. The male portion has a base with at least one locking leg, such that inserting the male portion into the female portion causes the locking leg to engage the locking slot to lock the male portion to the female portion. The male portion has a lever pivotably connected to the male portion, and a free end with a tongue extending into an interior of the male portion. The male portion has an engaging element connected to a free end of the locking legs and contacting the tongue, so that lifting the free end of the lever causes the tongue to push the engaging element toward the base of the male portion and move the locking legs inward to release the male portion from the female portion.
