Hybrid Baby Carrier With Ground Support Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby carriers concentrate the weight of a baby on the shoulders and waist of the guardian, leading to increased load on joints, particularly problematic for women who have given birth, as most guardians using these carriers are women.
Innovation Solution
A hybrid baby carrier design that includes a main body with a strap for shoulder support, a downwardly extended support unit to distribute the baby's weight towards the ground, and a waist support unit to maintain posture and reduce load, featuring transfer rollers and shock-absorbing units for comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hip-seat baby carrier is used, then the baby can be stably held or carried on the back, but the weight of the baby is concentrated on the shoulders and waist of the guardian, adding load to the shoulders, waist, and knees
Solution Approach 1:
The baby carrier is divided into distinct functional components: a main body for holding the baby, a support unit extending downward to distribute weight, and a transfer roller mechanism. This segmentation allows the weight distribution function to be separated from the baby-holding function, enabling the support unit to bear and distribute the load to the guardian's legs rather than concentrating it on the shoulders and waist.
Solution Approach 2:
The transfer roller acts as an intermediary mechanism between the main body and the support unit. It facilitates the transfer of the baby's weight from the main body to the support unit, which then distributes the load to the guardian's legs. This intermediary mechanism enables smooth weight redistribution without directly loading the shoulders and waist.
2Device complexity
If a conventional baby carrier concentrates weight on the shoulders and waist, then the structure can be simple, but it creates difficulty for women who have given birth to use the carrier due to increased joint load
Solution Approach 1:
By segmenting the carrier into a main body, support unit, and transfer roller mechanism, the design adds components to improve usability for postpartum women. The support unit extending downward and the transfer roller mechanism, while adding structural complexity, enable weight distribution to the legs, significantly reducing the burden on the waist and knees, thereby improving ease of operation for postpartum women.
Solution Approach 2:
The support unit extends downward from the main body, utilizing the vertical dimension to distribute weight. Instead of relying solely on the horizontal shoulder and waist support, the downward extension creates a new dimensional pathway for load distribution through the guardian's legs, reducing the harmful effects on the waist and knees.
3Stability of the object's composition
If the support unit is rigidly connected to the main body, then the main body rotates along with the support unit, but this may reduce flexibility and comfort
Solution Approach 1:
The transfer roller mechanism introduces dynamic elements to the connection between the main body and the support unit. Rather than a completely rigid connection, the roller allows for controlled movement and adjustment, enabling the main body to rotate along with the support unit while maintaining stability. This dynamic connection provides flexibility and comfort during use.

Function Achieved in This Case
The hybrid baby carrier effectively reduces the load on the guardian's shoulders and waist by distributing the baby's weight and providing shock absorption, making it easier and less fatiguing to carry a baby, while maintaining correct posture and preventing pressure on joints.
Implementation Method 1
a transfer roller connected to the lower end of the support unit
Implementation Method 2
featuring transfer rollers and shock-absorbing units for comfort and stability
