Solution Overview

Problem

Wrap and mei tai infant carriers have a high learning curve for proper use and can cause muscle fatigue and strain in caregivers due to uneven weight distribution, especially when carrying toddlers or older children.

Innovation Solution

A wrap-type infant carrier integrating features of mei tai and SSC carriers, with permanently attached wrap panels and a back harness, a belt pocket, and an extensible waist sash, to facilitate easy fitting and distribute weight more evenly across the caregiver's body, reducing muscle strain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wrap or mei tai carriers are used, then comfort and closeness are improved, but the learning curve and ease of operation deteriorate

Engineering Contradiction:

Improvecomfort and closenessVSAvoidlearning curve

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The carrier is divided into distinct functional components: wrap panels for comfort and closeness, a back harness for structural support, a belt pocket for weight distribution, and an extensible waist sash for stability. This segmentation allows each component to perform its specific function optimally while simplifying the overall donning process compared to traditional wraps.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The back harness acts as an intermediary structure that connects the wrap panels to the belt pocket and waist sash. This intermediary component provides a stable framework that guides the user through the donning process, reducing the learning curve while maintaining the comfort and closeness benefits of wrap carriers.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional wrap or mei tai carriers are used, then adaptability is improved, but weight distribution and muscle strain deteriorate

Engineering Contradiction:

Improvecarrier flexibilityVSAvoidmuscle fatigue and strain

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Different parts of the carrier have specialized properties optimized for their specific functions: the wrap panels provide softness and closeness, the back harness provides structural integrity, the belt pocket provides weight distribution, and the waist sash provides stability. This local quality optimization ensures adaptability while preventing muscle strain through proper load distribution.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The carrier distributes weight across multiple dimensions of the caregiver's body: the back harness distributes load vertically across the back, the belt pocket distributes weight horizontally across the hips, and the waist sash provides circumferential support. This multi-dimensional weight distribution prevents concentration of force in any single area, mitigating muscle fatigue and strain.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
