Buckle structure, buckle assembly and baby carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carrier buckle structures often experience 'false engagement' due to strap protrusion, leading to safety concerns and complicated, time-consuming operation, as the strap can bulge between the buckles and cause misalignment during magnetic attraction.
Innovation Solution
A buckle structure with an extending portion and opening allows the strap to pass through, preventing protrusion and ensuring precise engagement by bending the strap close to the buckle, thus eliminating 'false engagement' and facilitating quick and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the strap is inserted directly into the connecting port from the bottom, then the strap connection is simple, but the strap protrudes or bulges from the side adjacent to the male buckle, causing false engagement
Solution Approach 1:
The connecting port is divided into two functional parts: an opening for strap insertion and a connecting member for secure attachment. This segmentation allows the strap to be routed through the opening in a controlled manner, preventing protrusion while maintaining simple connection operation.
Solution Approach 2:
The extending portion acts as an intermediary structure between the opening and the connecting port. It guides the strap from the opening to the connecting member, ensuring the strap does not bulge outward and preventing false engagement while maintaining operational simplicity.
2Speed
If magnetic attraction is used for buckle engagement, then the engagement speed is fast, but it is difficult to adjust the buckles during engagement and false engagement is easily mistaken for true engagement
Solution Approach 1:
The strap is pre-routed through the opening and secured to the connecting member before the buckles engage. This preliminary action ensures the strap is in the correct position, preventing false engagement and allowing users to verify true engagement without compromising the speed advantage of magnetic attraction.
Solution Approach 2:
The structured connection through the opening and connecting member provides tactile and visual feedback that confirms proper strap positioning. This feedback mechanism allows users to distinguish between magnetic attraction (false engagement) and true engagement, maintaining ease of operation while ensuring reliability.
3Volume of moving object
If the lock portion is closer to the protective member, then the structural compactness is improved, but the protruded strap located between the buckles prevents firm engagement and creates false engagement state
Solution Approach 1:
The opening is positioned on the extending portion at an angle relative to the main buckle body, creating a three-dimensional strap routing path. This dimensional change allows the strap to pass through without protruding from the side adjacent to the male buckle, maintaining compactness while preventing false engagement.
Solution Approach 2:
The strap is nested within the structure formed by the extending portion and connecting member, rather than protruding outward. This nesting approach maintains the compact buckles structure while ensuring the strap does not interfere with the engagement between the female and male buckles.
