Buckle Assembly Nested Frame Reduces Snagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckle assemblies are prone to disengagement and snagging in environmental conditions, particularly in low-profile applications like protective garments used in combat or law enforcement, which can hinder movement and compromise protection.
Innovation Solution
A buckle assembly design featuring interlocking frame members with a pivot mechanism and recess configuration that maintains a compact, low profile, preventing unwanted disengagement and snagging, while allowing for secure tensioning of strap members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buckle assembly is designed with a low profile configuration, then the risk of unintentional disengagement and snagging is reduced, but the complexity of the assembly structure increases
Solution Approach 1:
The buckle assembly employs a nested structure where the third frame member is received within a recess of the second frame member, and the first frame member rotates about a pivot on the second frame member. This nesting arrangement achieves a low profile configuration that reduces snagging risk while maintaining structural integrity through multiple interlocking components.
Solution Approach 2:
The buckle assembly is divided into multiple separate frame members (first, second, and third frame members) that can be assembled independently. Each frame member serves a specific function: the first frame member provides the slot for strap insertion, the second frame member provides the recess for low-profile configuration, and the third frame member provides additional structural support. This segmentation allows for simplified manufacturing and assembly while achieving the desired low-profile configuration.
2Reliability
If the buckle assembly is designed to remain securely engaged during operations, then protective garment positioning is maintained, but the device complexity increases
Solution Approach 1:
The buckle assembly incorporates a pivot member that enables the first frame member to rotate relative to the second frame member. This dynamic mechanism allows the buckle to transition between open and closed positions during operation, providing secure engagement when needed while maintaining ease of adjustment. The rotational capability ensures reliable engagement during combat or law enforcement operations without requiring an overly complex locking mechanism.

AI summary
A buckle assembly includes a first frame member defining a first slot, which includes a first open end positioned at a first side of the first frame member and which includes a first closed end positioned spaced apart from a second side of the first frame member; a second frame member defining a second slot, which includes a second open end positioned at a second side of the second frame member and a second closed end positioned spaced apart from a first side of the second frame member, wherein one of the first or second frame members has a pivot member upon which the first and second frame members are rotatable relative to one another; and a third frame member defining at least two slots which extend through the third frame member and is configured to position within a recess defined within the second frame member.
