Child Carrier with Segmented Adjustable Support for Variable Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child carriers often fail to provide a flexible and comfortable seating arrangement for children of different sizes, as they typically have a fixed space configuration that does not adapt to varying child dimensions or positions.
Innovation Solution
A child carrier design featuring a carrying harness with a child supporting part that includes a torso support portion and a neck support portion, which are detachably connected via a fastener, allowing for adjustable positions and a bib that can be installed to cover the neck support portion, along with a hip support adjustment mechanism that modifies the width of the hip support portion using a strap system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed space configuration is used for seating a child, then the structure is simple and easy to manufacture, but it cannot adapt to children of different sizes and positions
Solution Approach 1:
The child carrier is divided into multiple detachable segments including a torso support portion, neck support portion, and hip support portion. These segments can be connected or separated based on the child's size and position requirements, allowing the carrier to adapt to different children without requiring a completely different structure for each size.
Solution Approach 2:
The carrier incorporates adjustable and reconfigurable elements such as the detachable neck support portion and adjustable hip support width that can be dynamically modified. The fastening system allows the structure to transition between different configurations to match varying child dimensions and carrying positions.
2Adaptability or versatility
If a detachable neck support portion is added to allow position adjustment, then adaptability improves, but device complexity increases
Solution Approach 1:
The neck support portion is separated from the torso support portion as an independent detachable component. This segmentation allows the neck support to be adjusted, removed, or repositioned independently, providing adaptability for different child sizes and comfort needs without complicating the entire structure.
Solution Approach 2:
The fastening mechanism serves multiple functions: it secures the neck support portion to the torso support portion, allows for easy detachment and reattachment, and provides position adjustment capability. This multi-functionality reduces the need for separate mechanisms for each function, thereby limiting the increase in overall device complexity.
3Adaptability or versatility
If the hip support width is made adjustable to fit different children, then versatility improves, but the ease of operation deteriorates
Solution Approach 1:
The hip support portion incorporates an adjustable width mechanism that allows the support to be dynamically resized to match different child hip dimensions. This dynamic adjustment capability ensures proper fit and comfort for various child sizes while maintaining relatively simple operation through intuitive adjustment mechanisms.

AI summary
A child carrier includes a carrying harness, a child supporting part connected with the carrying harness, the child supporting part including a torso support portion and a neck support portion connected with each other, and a bib installable on the child supporting part to at least partially cover the neck support portion. The neck support portion is foldable over the torso support portion for adjusting the neck support portion to a desirable vertical position relative to the torso support portion, and the torso support portion includes a plurality of fastening parts operable to respectively engage with the neck support portion and the bib to hold the neck support portion in the desirable vertical position and the bib in position adjacent to the neck support portion.
