Convertible Infant Car Seat Chassis for Multi-Mode Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant transport systems, such as those combining car seats and strollers, lack flexibility in configuration options, failing to provide a desired range of transport modes efficiently.
Innovation Solution
A modular infant transport system comprising a chassis, base, and infant car seat that can be converted between a car seat, carrier, and stroller configurations through releasable mechanisms, allowing for multiple transport conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional infant carriers or car seats are used, then the infant can be transported, but the system lacks flexibility in configuration options and cannot provide multiple transport modes
Solution Approach 1:
The infant transport system is divided into separate modular components: a base unit, a carrier unit with shell and harness, and optional stroller components. These segments can be independently assembled and configured to create different transport modes (car seat mode, carrier mode, stroller mode), providing versatility while keeping each individual component relatively simple.
Solution Approach 2:
The carrier unit is designed as a universal component that can function in multiple transport configurations. The same carrier unit can be attached to the base for car seat use, carried independently as a baby carrier, or mounted on a stroller frame, eliminating the need for multiple specialized devices.
2Adaptability or versatility
If a multi-functional infant transport system is created, then versatility is improved, but the ease of operation decreases due to complex assembly and disassembly requirements
Solution Approach 1:
The carrier unit is pre-equipped with attachment mechanisms and interface components that align with corresponding features on the base and stroller frames. This preliminary configuration of attachment points and locking mechanisms enables quick connection and disconnection without requiring complex assembly procedures, maintaining ease of operation despite multi-functionality.
3Adaptability or versatility
If the system allows multiple transport configurations, then adaptability increases, but the device complexity increases with additional mechanisms and components
Solution Approach 1:
The carrier unit serves as a universal interface that can attach to different base types and stroller frames using standardized connection mechanisms. This universality allows the system to achieve multiple transport configurations without requiring unique specialized components for each mode, thereby limiting the increase in overall device complexity.

AI summary
A convertible infant car seat and stroller assembly is provided, comprising: an infant car seat shell; and a chassis coupled to the infant car seat, comprising: a frame; a pair of rear legs pivotally coupled to the frame; and a pair of front legs, each front leg pivotally coupled to a respective rear leg, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition usable as in infant car seat, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition usable as a stroller; wherein, in the second transport condition, the front legs and the rear legs are releasably secured to the chassis frame in the deployed position to prevent the front legs and the rear legs from pivoting.
