Child Carrier Leg Support Adjustability for Multi-Size Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child carriers lack adjustability and comfort, particularly in supporting a child's legs and head, which can lead to discomfort and insecurity for both the child and the adult carrying them, and are not cost-effective in manufacturing.
Innovation Solution
The development of highly adjustable child carriers with expandable leg supports and adjustable head rests, utilizing a captive draw string and zipper mechanisms to customize the fit and support, along with breathable and elastic fabrics for comfort, allowing for multiple deployment positions to accommodate different child orientations and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed-size leg supports are used in child carriers, then the manufacturing cost is reduced, but the adaptability to different child sizes and orientations is worsened
Solution Approach 1:
The leg supports are designed to be expandable and adjustable in size, transforming from a static fixed-size component to a dynamic adjustable component. This allows the leg supports to adapt to different child sizes and orientations while maintaining cost-effectiveness through a modular design that expands from a base structure.
Solution Approach 2:
The leg supports are divided into multiple segments or panels that can be independently adjusted and reconfigured. This segmentation allows the carrier to accommodate different child sizes by adjusting individual segments rather than requiring completely different carrier sizes, resolving the contradiction between manufacturing simplicity and adaptability.
2Ease of operation
If adjustable leg supports and head rests are added to child carriers, then the comfort and security for child and adult are improved, but the device complexity increases
Solution Approach 1:
The adjustable leg supports and head rests are integrated into the existing carrier structure in a nested manner, where adjustment mechanisms are incorporated within the fabric panels and straps rather than adding separate external components. This reduces overall device complexity while maintaining adjustability and comfort features.
Solution Approach 2:
The carrier components are designed to serve multiple functions: the leg supports provide both structural support and comfort adjustment, while the head rest integrates with the carrier strap system. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity while improving comfort and security.
3Adaptability or versatility
If multiple deployment positions are provided for different child orientations, then the versatility is improved, but the manufacturing complexity increases
Solution Approach 1:
The carrier employs dynamic adjustment mechanisms that allow the same physical structure to be reconfigured for different child orientations (front-facing, back-facing, side-facing). Rather than manufacturing multiple fixed-position carriers, the design uses adjustable straps, expandable panels, and reconfigurable support structures that can be dynamically positioned to create multiple deployment configurations from a single carrier unit.

AI summary
Adjustable child carriers are disclosed. A disclosed example child carrier includes a child support pouch to receive a child in a substantially upright position, where the child support pouch includes an upper pouch area, a medial pouch area and a lower pouch area. The example child carrier also includes a harness to support the child support pouch on an adult, where the harness includes a first upper strap coupled to the upper pouch area, a second upper strap coupled to the upper pouch area, and a lower strap coupled to the medial pouch area. The example child carrier also includes a first leg support coupled to the child support pouch at the lower pouch area, where the first leg support pouch has a first continuously adjustable operative surface area, and a second leg support coupled to the child support pouch at the lower pouch area, where the second leg support pouch having a second continuously adjustable surface area.
