Dual-Loop Child Carrier With Adjustable Back Cross Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable child and pet carriers are uncomfortable, difficult to use, and lack versatility in carrying positions, often causing strain on the user's shoulders and back, and do not provide adequate support or security for the child or animal.
Innovation Solution
A wearable carrier comprising two loops of fabric connected by a sliding support band that allows for adjustable cross positioning on the user's back, with an optional sash for added security and comfort, providing various carrying positions without bulky padding or hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If structured carriers with hard or bulky material are used, then the child is securely supported, but the carrier becomes uncomfortable and cumbersome for the user
Solution Approach 1:
The patent employs soft, flexible fabric material instead of hard or bulky structured material. The fabric loops and connecting devices create a supportive structure that conforms to the user's body, providing both child support security and user comfort through flexibility and softness.
Solution Approach 2:
The carrier incorporates adjustable fabric loops and sliding connecting devices that allow dynamic adaptation to different user bodies and carrying positions. This adjustability enables the soft fabric structure to provide reliable child support while maintaining user comfort across various configurations.
2Adaptability or versatility
If multiple adjusting devices are added to structured carriers, then the fit is improved, but the device complexity increases
Solution Approach 1:
The carrier is divided into separate fabric loops and connecting devices that can be independently adjusted. This segmentation allows for versatile fit adjustment across different body sizes and carrying positions without requiring a single complex adjusting mechanism.
Solution Approach 2:
The sliding connecting devices enable dynamic adjustment of the fabric loops to achieve proper fit. This simple sliding mechanism provides adaptability without the complexity of multiple fixed adjusting components.
3Strength
If hardware connecting devices are used, then the structural integrity is maintained, but the carrier becomes difficult to wash and maintain
Solution Approach 1:
The patent replaces traditional hardware connecting devices with soft fabric connecting devices that are integrated into the fabric loops. This eliminates metal or plastic hardware that would complicate washing, while the fabric construction maintains structural integrity through its flexible, interwoven design.
Solution Approach 2:
The connecting devices are merged with the fabric loops rather than being separate hardware components. This integration allows the entire carrier to be washed as a single fabric item, eliminating the maintenance issues associated with detached hardware while preserving structural strength.
4Device complexity
If one-shoulder slings are used, then the carrier is simple and lightweight, but the user experiences shoulder strain and lack of back support
Solution Approach 1:
The carrier uses two separate fabric loops instead of a single sling, distributing the load across both shoulders and the back. This segmentation reduces shoulder strain while maintaining simplicity and lightness of the overall design.
Solution Approach 2:
The carrier transitions from a one-dimensional single-shoulder sling to a two-dimensional dual-loop configuration that engages both shoulders and the back. This dimensional change distributes weight more evenly, reducing harmful strain while preserving carrier simplicity.
5Ease of manufacture
If fabric material is used instead of structured material, then the carrier is washable and portable, but the support and security are reduced
Solution Approach 1:
The fabric loops are designed with dynamic adjustability, allowing them to be tightened and configured to provide adequate support. This adjustability compensates for the softness of fabric material, ensuring reliable child support while maintaining washability and portability.
Solution Approach 2:
The patent uses soft fabric material that conforms to the child's body, providing support through flexibility and adaptability rather than rigid structure. The fabric's ability to mold to the child's shape maintains support capability while enabling washing and portability.
6Device complexity
If the loops are fixed in position, then the carrier structure is simple, but the user cannot adjust the crossing position on the back
Solution Approach 1:
The connecting devices are designed to slide along the fabric loops, enabling dynamic adjustment of the crossing position on the user's back. This simple sliding mechanism provides adaptability without significantly increasing structural complexity.
Solution Approach 2:
The connection between loops is segmented into adjustable segments rather than a fixed connection. This allows the crossing position to be moved along the loops while maintaining the overall simplicity of the fabric-based carrier structure.

AI summary
A child or animal carrier and a method of carrying a child or animal on the user's body are described in this invention. The carrier has two loops 1, 2 joined together by a connecting device with an optional sash. The method of carrying the child or animal involves wearing the loops 1, 2 and placing the child or animal in the loops 1, 2 in a variety of positions. In certain positions the child is carried vertically on the front of the user's torso and either faces the same direction as the user or faces inward toward the user's torso; or the child is carried vertically on the user's back facing toward the user's back. In other positions, a child or animal can be fully or partially cradled in the loops 1, 2. In another position, the child or animal is slung in the loops 1, 2 and carried against the user's hip or at the front of the user's torso. The connecting device allows the user to adjust the position of the loops 1, 2 for comfort and back support. In addition, the optional sash can be used to provide additional security for the child, and added comfort and support for the user and child. The carrier is easy to use and designed for the comfort of the user and comfort and security of the child or animal.
