Buckle Assembly Locking Channel and Guiding Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckle assemblies experience unreliable locking and excessive relative movement between buckle members, leading to potential detachment under impact, vibration, and stress, resulting in insecure fastening.
Innovation Solution
A buckle assembly design featuring a locking arrangement with resilient elements, locking protrusions, and a guiding member to minimize lateral movement, ensuring secure engagement between the first and second buckle members through a locking channel and guiding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional buckle latches are used to lock the first and second buckle members, then the buckle assembly can be operated conveniently, but the locking reliability is insufficient and accidental actuation may occur
Solution Approach 1:
The locking mechanism is divided into two independent parts: buckle latches for convenient operation and a locking arrangement (locking protrusions and guiding members) for reliable engagement. The locking protrusions extend from the insertion member and engage with corresponding guiding members on the second buckle member, creating separate locking and operating functions that resolve the contradiction between reliability and ease of operation.
2Stability of the object's composition
If the first and second buckle members are engaged using conventional mechanisms, then the structure remains simple, but excessive relative movement occurs between the buckle members under impact and vibration
Solution Approach 1:
The guiding members act as intermediaries between the locking protrusions and the second buckle member body. These guiding members receive and guide the locking protrusions into proper engagement, minimizing lateral movement while maintaining a relatively simple overall structure. The receiving slot also serves as an intermediary feature that guides and constrains the insertion member's movement path.
3Reliability
If conventional buckle engagement is used, then the manufacturing process remains simple, but the engagement becomes loose under repeated use and vibration, potentially leading to detachment
Solution Approach 1:
The locking protrusions are pre-formed on the insertion member during manufacturing, and the receiving slot is pre-formed on the second buckle member. This preliminary formation of locking features ensures proper alignment and engagement from the first use, preventing progressive loosening under vibration and repeated use while maintaining manufacturing simplicity through integral forming where possible.

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 design enhances locking performance by minimizing lateral movement and maintaining secure engagement between buckle members, even under stress and vibration, preventing accidental detachment.
Implementation Method 1
a plurality of resilient elements mounted in the second buckle body to normally exert an urging force to normally retain the first buckle latch and the second buckle latch in the locked position respectively

AI summary
A buckle assembly includes a first buckle member having an insertion member, a second buckle member, a first buckle latch, a second buckle latch, a plurality of resilient elements, and a locking arrangement. The locking arrangement includes at least two locking protrusions and at least one guiding member. The locking protrusions are extended from one of the insertion member and the second buckle body, and are arranged to form a locking channel between the two locking protrusions. The guiding member is extended from the remaining one of the insertion member and the second buckle body, and is arranged to be inserted in the locking channel formed by the locking protrusions so as to retain the first buckle member to be locked with the second buckle member when the first buckle latch and the second buckle latch are in the locked position.
