Modular Infant Carrier Chassis With Deployable Nesting Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant transport systems, such as those combining car seats and strollers, lack flexibility in configuration options and often require complex or cumbersome transitions between modes of use.
Innovation Solution
A modular infant transport system with a chassis, base, and infant car seat that allows for seamless conversion between a vehicle seat, carrier, and stroller through a combination of release mechanisms and deployable legs, enabling multiple configurations with ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional infant carriers are used, then the structure is simple, but the configuration options are limited
Solution Approach 1:
The infant transport system is divided into separate modular components: a base unit, a carrier unit with shell and harness, and a stroller unit with chassis and legs. These segments can be independently used or combined in different configurations, providing versatility while keeping each component relatively simple in structure.
Solution Approach 2:
The carrier unit is designed to serve multiple functions: it can be used as a standalone infant carrier, attached to the base as a car seat, or mounted on the stroller chassis. The shell and harness assembly is universal across all three modes of transport, eliminating the need for separate systems.
2Adaptability or versatility
If convertible systems are used, then multiple configurations are possible, but transitions between modes are cumbersome
Solution Approach 1:
The carrier unit is pre-designed with standardized attachment interfaces that match both the base and stroller chassis. The shell and harness are pre-configured to engage with locking mechanisms on either the base or stroller, allowing for quick mode transitions without complex assembly or disassembly steps.
Solution Approach 2:
The system incorporates movable and adjustable components such as the stroller legs that can be deployed or retracted, and the carrier attachment points that can be quickly engaged or disengaged. This dynamic design allows smooth transitions between folded and unfolded states, and between different transport modes.
3Adaptability or versatility
If stroller legs are deployed, then stroller mode is achieved, but the structure becomes more complex
Solution Approach 1:
The stroller legs are designed to nest within each other when folded, with the front legs storing inside the rear legs. This nested configuration minimizes the structural footprint and simplifies the overall appearance when not in use, while still providing full stroller functionality when deployed.
Solution Approach 2:
The legs incorporate pivot joints and locking mechanisms that allow them to be easily deployed and secured. The dynamic design enables the legs to transition between folded and extended positions, providing stroller mode when needed while maintaining a compact form when not in use.

AI summary
A system to transport infant children is provided. The system comprises a chassis having a frame; a pair of rear legs pivotally coupled to the frame at a rear leg pivoting axis; and a pair of front legs, each front leg pivotally coupled to a respective rear leg at a front leg pivoting axis, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition. The system may also comprise an infant car seat coupled to the chassis.
