Solution Overview

Problem

Soft-structured child carriers often limit leg and arm movement, restrict the child to a single position, and fail to accommodate a range of child ages and sizes, leading to potential ergonomic issues and the need for separate infant inserts that can be cumbersome and difficult to manage.

Innovation Solution

A soft-structured child carrier with adjustable shoulder strap attachment panels that reduce tension on the body panel, allowing for easy height and width adjustments, and the ability to configure the body panel to accommodate different child sizes through various folding and positioning options, providing ergonomic support and enhanced freedom of movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If soft-structured carriers use stitching and fabrics to provide structure, then the wearer gains freedom of hand and arm movement, but the child's leg and arm movement is unduly limited

Engineering Contradiction:
Improvewearer freedom of hand and arm movementVSAvoidchild leg and arm movement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The shoulder straps are designed to be movable and adjustable, allowing the carrier to adapt dynamically to different carrying positions and child sizes. The straps can be repositioned to accommodate various configurations, providing both wearer comfort and child mobility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The carrier is divided into separate functional components including shoulder straps, waistband, and body panel. This segmentation allows each component to be optimized independently - the shoulder straps for wearer comfort and the body panel for child movement freedom.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If soft-structured carriers are designed for a limited age and size range, then the carrier structure can be simplified, but the carrier cannot accommodate children as they grow

Engineering Contradiction:
Improvecarrier structureVSAvoidaccommodation of different child ages and sizes
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The carrier incorporates adjustable elements including shoulder straps with multiple attachment points and a body panel that can be folded or extended. This dynamic design allows the same carrier to accommodate infants through toddlers without requiring structural redesign.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The carrier is designed as a universal solution that can serve multiple age groups and carrying styles. The adjustable shoulder straps and flexible body panel enable the carrier to adapt to different child sizes and developmental stages.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a separate infant insert is used to accommodate smaller infants, then the carrier can support younger children, but the device complexity increases and the insert is cumbersome to manage

Engineering Contradiction:
Improvesupport for infant sizesVSAvoidnumber of separate devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carrier integrates all necessary support features directly into the main structure. The body panel is designed with inherent flexibility and adjustability that eliminates the need for separate infant inserts, combining multiple functions into a single unified device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier is designed as a universal solution that accommodates both infants and older children without requiring additional accessories. The adjustable shoulder straps and flexible body panel provide the necessary support for all age groups within a single device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Device complexity

If the carrier is designed to support a child in a non-ergonomic upright position, then the carrier structure is simplified, but the child's pelvic development is impeded

Engineering Contradiction:
Improvecarrier structureVSAvoidstress on infant's sacrum and pelvic development
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The body panel is designed with specific local characteristics that provide ergonomic support at critical areas. The panel's shape and flexibility are optimized to support the child's pelvis and spine in healthy positions, distributing weight appropriately without requiring complex structural elements.

Inventive Principle:
Principle #3Local quality

AI summary

A soft-structured child carrier that includes a body panel having a bottom end attached to a bottom portion of the waistband, a first shoulder strap, a second shoulder strap, a first shoulder strap attachment panel attached to the interior side of the body panel away from the side edges of the body panel and a second shoulder strap attachment panel attached to the interior side of the body panel and away from the side edges of the body panel. The first shoulder strap attachment panel provides a first flap that is movable away from the interior surface of the body panel and includes a first lower attachment point for the first shoulder strap. The second shoulder strap attachment panel provides a second flap that is movable away from the interior surface of the body panel and includes a second lower attachment point for the second shoulder strap.
