Rotating Baby Carrier Strap Mechanism for Solo Chest-to-Back Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carriers face difficulties in safely rotating from the chest side to the back side while carrying a child, especially when alone, due to challenges in positioning the child on the back and transferring the carrier without compromising safety for both the child and the wearer.
Innovation Solution
A baby carrier design featuring adjustable chest straps connected by a means that allows rotation around the wearer's body, with a waist belt and carrier bag configuration that redistributes weight during rotation, ensuring the child's safety and ease of transfer between chest and back sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the carrier is placed on the back side of the wearer, then it is suitable for carrying heavier children, but it becomes difficult to position the child into the carrier when alone
Solution Approach 1:
The carrier is designed to be dynamically repositionable between chest and back sides through rotation around the wearer's body. The connection means allows the carrier to rotate while maintaining secure attachment, enabling transition from a positioning-friendly chest position to a weight-capable back position without requiring assistance.
2Ease of operation
If the carrier is placed on the chest side of the wearer, then it is easy to position the child into the carrier, but it becomes difficult to rotate the carrier to the back side safely
Solution Approach 1:
A connection means acts as an intermediary between the chest straps and the carrier bag, enabling controlled rotation. This connection mechanism ensures the carrier remains securely attached during the rotation process, preventing accidental detachment while allowing the wearer to safely transition the carrier from chest to back side.
3Device complexity
If the carrier uses fixed chest straps connected at the back, then the structure is simple, but the carrier cannot be rotated from chest side to back side
Solution Approach 1:
The chest strap connection is transformed from a fixed static structure to a dynamic rotating structure. The connection means allows the straps to maintain their simple back-connection configuration while enabling rotational movement, providing position flexibility without significantly increasing structural complexity.

AI summary
A baby carrier includes chest straps, a waist belt, and a carrier bag mounted to the chest straps and the waist belt. The carrier bag has a front piece, with a lower portion of the front piece being connected to the waist belt. A connection between the chest straps is adapted to be achieved by an element, and a second part of the respective chest strap is connected to a middle portion of the front piece so as to permit the baby carrier to be rotated around an upper part of the body of a wearer. During one step of the rotation of the baby carrier, the element extends over one shoulder of the wearer and carries the weight which in the normal case is carried by the chest straps.
