Baby Carrier Lower Connection Structure for Vertical Waist Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby carriers with relief belts experience discomfort due to the downward rotation of the upper edge of the relief belt, which presses against the stomach, and the buckle placement on the backside is hard to reach and poses a risk of accidental opening when bending, especially when carrying heavier children.
Innovation Solution
A baby carrier design featuring a lower connection device with articulatable fastening ears and a band-shaped sit part that attaches to the relief belt, providing a vertical, plane contact surface and minimizing pressure on the wearer, along with a buckle placement on the chest side for easier access and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the lower part of the carrying pocket is attached to the upper edge of the relief belt, then the relief belt can support heavier children, but the upper edge of the relief belt rotates downward and outward causing discomfort
Solution Approach 1:
The connection device introduces a new spatial dimension by positioning the buckle on the chest side rather than the back side, and by using articulatable fastening ears that can rotate to accommodate the load. This dimensional repositioning allows the relief belt to maintain proper orientation while supporting heavier children.
Solution Approach 2:
The patent changes the orientation parameter of the relief belt from horizontal attachment at the back to vertical attachment at the chest side. This parameter change prevents the downward rotation that causes discomfort while maintaining the load-bearing capability.
2Reliability
If the buckle is placed on the back side of the wearer, then the relief belt can be closed securely, but it is hard to reach and may open accidentally when bending
Solution Approach 1:
The patent inverts the conventional buckle placement from the back side to the chest side. This inversion makes the buckle easily accessible to the wearer while maintaining secure closure through the articulatable fastening mechanism that prevents accidental opening.
3Strength
If a stiff connection device is used to attach the lower part of the carrying pocket to the relief belt, then the attachment is secure, but it enhances the feeling of discomfort when the child becomes heavier
Solution Approach 1:
The connection device uses articulatable fastening ears that can rotate dynamically to accommodate the weight of the child. This dynamic adjustment prevents the stiff connection from pressing against the stomach while maintaining secure attachment of the carrying pocket.

AI summary
Baby carrier comprising two strap loops (2a, 2b), which are interconnected and arranged to extend around the two shoulder areas of the wearer, a relief belt (3) that extends around the waist of the wearer, which relief belt (3) is connected with the respective strap loop, and a carrying pocket (10) that is mounted to the strap loops and the relief belt and has a front piece (11) having at least one free side edge that can be attached to an adjacent strap loop (2a, 2b) by means of an upper connection device (5a, 5b), and a sit part (14) that can be attached to the relief belt (3) by means of a lower connection device (16). The front piece (11) and the relief belt (3), below the upper connection device, define a leg opening. The lower connection device (16) comprises an intermediate piece (110) to which the sit part (14) can be attached, as well as a fastening member (111) arranged at each side and at least one of which detachably attached to the intermediate piece, and the respective part (17) of the relief belt (3) can be attached to the respective fastening member for the provision of vertically turnable attachment of the relief belt to the lower connection device.
