Adjustable Child Carrier Seat Coupling for Growing Child Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child carriers lack the flexibility to adjust the seat depth to accommodate the varying size of children as they grow, compromising safety and comfort.
Innovation Solution
The child carrier features adjustable seat depth through a system of couplers and a track-clasp mechanism, allowing for continuous or discrete adjustments to ensure a secure and comfortable fit for children of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat depth is fixed in existing child carriers, then the structure is simple and easy to manufacture, but the carrier cannot accommodate children of different sizes as they grow
Solution Approach 1:
The patent implements a dynamic seat depth adjustment mechanism where the torso support can be repositioned along the seat at multiple discrete locations. This allows the seat depth to change from fixed to adjustable, enabling the carrier to adapt to children of different sizes while maintaining a relatively simple structural design through the use of discrete coupling positions rather than continuous adjustment mechanisms.
Solution Approach 2:
The adjustment mechanism is segmented into discrete coupling locations along the seat, with couplers that can engage at specific positions. This segmentation allows for size adaptation without requiring a complex continuous adjustment system, balancing adaptability with structural simplicity through predefined adjustment points.
2Duration of action of stationary object
If the seat depth is adjustable to fit growing children, then the carrier remains safe and comfortable longer, but the adjustment mechanism increases device complexity
Solution Approach 1:
The dynamic adjustment capability allows the carrier to maintain safety and comfort over a longer period by adapting to the child's growth. The torso support can be repositioned as the child grows, extending the usable duration of the carrier without requiring a completely new product, while the adjustment mechanism remains relatively simple through discrete coupling points.
Solution Approach 2:
The adjustable seat mechanism serves multiple functions: it accommodates different child sizes, extends the carrier's usable life, and maintains safety and comfort across various growth stages. This multi-functionality justifies the added complexity by providing long-term value and adaptability.
3Device complexity
If discrete coupling locations are used for adjustment, then the structure remains relatively simple, but continuous adjustment range is limited
Solution Approach 1:
The seat depth adjustment is segmented into multiple discrete coupling locations distributed along the seat. This segmentation provides a balance between structural simplicity and adjustment range, offering sufficient adaptability for children of different sizes while maintaining a straightforward implementation through predefined engagement points rather than continuous mechanisms.

AI summary
A carrier for transporting a child by a transporting individual. The carrier includes a belt, a seat, a torso support, and one or more couplers. The belt is configured for securing about the waste and/or hips of the transporting individual; the seat is coupled to the belt, is configured for at least partially supporting the child if the child is seated in the carrier, and has a surface configured for at least partially supporting at least part of the posterior of the child; the torso support is coupled to the seat by one or more couplers and is configured for supporting at least part of the torso of the child; and the one or more couplers are configured to enable adjustment of a distance between one or more coupling locations for each of the one or more couplers and a selected reference point.
