Solution Overview

Problem

Changing a baby on the go is challenging due to the lack of convenient and sanitary surfaces, and existing solutions fail to securely and conveniently carry infant and adult accessories, often leading to distractions and loss of items while using an infant stroller.

Innovation Solution

A convertible backpack with a removable inner caddy that attaches to a stroller, featuring a sanitary changing surface, zippers, and adjustable compartments to securely store and access baby and adult items, including a wedge-shaped opening for a cell phone, allowing hands-free use while maintaining attention on the infant.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If parents carry multiple baby care accessories manually, then they can access items when needed, but their hands are occupied and attention is diverted from the infant

Engineering Contradiction:

Improvehand-free operationVSAvoidattention to infant

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The accessory system is segmented into multiple pouches and compartments that can be independently attached to the stroller frame, allowing organized storage and easy access to specific items without handling the entire collection. Each pouch can be accessed independently while keeping hands on the stroller.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stroller frame acts as an intermediary structure that carries all necessary accessories. Instead of parents directly carrying items, the stroller serves as the carrying medium, freeing parental hands while keeping items securely attached and accessible through the intermediary stroller structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If parents find a baby changing station, then they can change the diaper hygienically, but they cannot carry other accessories conveniently

Engineering Contradiction:

Improvehygiene during changingVSAvoidcarrying capacity for accessories

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The stroller system is designed with multi-functionality, serving both as a transportation device and as a carrying system for multiple accessories including changing supplies. The universal attachment system allows the same stroller structure to support diaper changing materials, food, beverages, and other baby care items simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the changing station function with the accessory carrying system by integrating changing supplies into the pouches attached to the stroller. This combination allows parents to have both the changing surface (when needed) and all other accessories available in one unified mobile system.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If accessories are ported together in a backpack, then they are secure, but access requires two hands and diverts attention from the infant

Engineering Contradiction:

Improvesecurity of accessoriesVSAvoidaccess to items

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The accessory storage system transitions from a vertical backpack configuration to a horizontal distribution along the stroller frame. Instead of stacking items vertically in a bag that requires opening and digging, accessories are distributed across multiple pouches attached to the stroller's frame, allowing lateral access while maintaining security through distributed attachment points.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If a fixed caddy is attached to the stroller, then items are easily accessible, but the structure becomes complex and bulky

Engineering Contradiction:

Improveaccess to accessoriesVSAvoidstroller structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Instead of a single fixed caddy structure, the system is segmented into multiple independent pouches that can be attached to various points on the stroller frame. This segmentation allows for simplified individual components rather than one complex integrated structure, reducing overall system complexity while maintaining accessibility.

Inventive Principle:

Principle #1Segmentation

AI summary

A stroller caddy is provided. The stroller caddy includes a smaller removable secondary caddy that is nested within a larger primary caddy. Each of the primary and secondary caddy includes straps for independently connecting each caddy to the handlebars of an infant stroller. When nested, the secondary caddy is connected to the primary caddy near the top opening of the primary caddy. A top panel of the secondary caddy provides beverage and cell phone receptacles. A top flap is provided to cover the top opening. The primary caddy serves as a diaper bag that can be carried like a backpack. The front panel of the primary caddy unzips on both sides to provide access from the front to a cabinet-like main compartment having one or more adjustable shelves. The front panel unfolds again to provide a sanitary and private baby-changing surface.
