Solution Overview

Problem

Existing infant wagons lack an adapter to securely couple with infant car seats, leading to discomfort for infants transitioning from vehicles, limited space for carrying possessions, and inconvenience for caregivers.

Innovation Solution

A highly compatible car seat adapter with a quadrangular frame structure that symmetrically couples to infant wagons, supporting various infant car seats with multiple coupling structures, allowing seamless transition and expanding wagon usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an infant wagon is used without a car seat adapter, then the wagon can be used for carrying infants, but the infant experiences discomfort during transition from vehicle and the caregiver must carry the infant separately

Engineering Contradiction:
Improveease of transition from vehicle to wagonVSAvoidstability of infant in wagon
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A car seat adapter is introduced as an intermediary component that couples the infant car seat to the infant wagon. The adapter includes a coupling structure with fastening members that securely attach to the car seat's coupling structure, and a support structure with leg rest members that provide infant support. This mediator enables seamless transition while maintaining infant stability and comfort.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If the infant wagon interior space is used for infant seating, then the infant can be transported, but the space for storing possessions becomes narrow

Engineering Contradiction:
Improvespace for storing possessionsVSAvoidconvenience for caregiver
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The infant transportation system is segmented into two functional zones: the car seat adapter with support structure provides infant seating and support, while the freed interior space of the infant wagon is available for storing possessions. This segmentation allows simultaneous optimization of infant comfort and storage capacity.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If a car seat adapter is designed to be compatible with multiple car seat types, then usability is expanded, but the adapter structure becomes more complex

Engineering Contradiction:
Improvecompatibility with various car seatsVSAvoidcomplexity of adapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The car seat adapter is designed with a universal coupling structure that can interface with different car seat coupling structures. The support structure includes adjustable leg rest members that can accommodate various infant positions and car seat configurations. This multi-functionality enables compatibility with multiple car seat types while maintaining a relatively simple adapter design.

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

AI summary

Provided is a highly compatible car seat adapter for wagons which is capable of stably coupling an infant car seat installed in a vehicle to an infant wagon upon arrival at a destination, whereby it is possible to provide the same ride comfort to an infant and to minimize resistance of the infant when changing from the vehicle to the infant wagon, which is enabled by mounting the infant car seat to an upper end of the infant wagon, and thus, it is possible to use the interior space of the infant wagon as a luggage carrier, which enables leisurely movement, and the car seat adapter is compatible with each of a plurality of infant car seats having various shapes and coupling structures so as to be stably separably coupled to the infant wagon, whereby it is possible to expand usability of the infant car seat.
