Adaptive Leg Support Structure for Multi-Position Child Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant carriers are limited in carrying modes, age, weight, and size, restricting the comfort and versatility for both parents and children, as they are designed for specific configurations without the ability to adjust to different child positions or sizes.
Innovation Solution
The child carrier design includes adjustable upper-leg-support parts that can be coupled to the hip belt, allowing the child's thighs to be supported either perpendicular or parallel to their body, enabling various carrying positions such as sitting or hanging, and accommodating different child sizes and weights by adjusting strap configurations and using a cradle insert for infants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the carrier is designed for a specific carrying mode and child size, then the structural design is simplified, but the adaptability to different children and carrying positions is reduced
Solution Approach 1:
The leg support structure is designed to be dynamically adjustable, allowing it to transition between supporting the child's legs in a sitting position and allowing them to hang freely. This dynamic capability enables the same carrier structure to adapt to multiple carrying modes (front, back, hip) and different child positions without requiring multiple specialized carriers, thus resolving the contradiction between structural simplicity and carrying mode adaptability
2Manufacturing precision
If the leg support structure is fixed in position, then the manufacturing precision is improved, but the comfort for different child positions is reduced
Solution Approach 1:
The leg support structure incorporates adjustable mechanisms that allow the support position and angle to be dynamically modified according to the child's age, size, and preferred carrying position. This dynamic adjustability maintains manufacturing precision for each fixed position while enabling optimal comfort across various carrying scenarios, resolving the contradiction between manufacturing precision and child comfort
3Ease of manufacture
If the carrier uses fixed strap configurations, then the ease of manufacture is improved, but the adaptability to different child sizes and weights is reduced
Solution Approach 1:
The strap system is segmented into multiple adjustable components with independent adjustment mechanisms. This segmentation allows each strap section to be independently adjusted to accommodate different child sizes and weights, while the modular segmented design remains relatively simple to manufacture compared to a completely custom-fitted single-configuration strap system, resolving the contradiction between ease of manufacture and child size adaptability

AI summary
A carrier for transporting a child by a transporting individual. The carrier includes a torso support part configured for supporting the torso of the child, a seat support part coupled to the torso support part, and at least one strap coupled to the torso support part and/or to the seat support part and with the torso support part and the seat support part configured to encircle at least part of the torso of the transporting individual. The seat support part is configured for supporting the posterior of the child in a sitting position in a first configuration, and the seat support part is configured for supporting the posterior of the child in a hanging position in a second configuration.
