Modular Stroller Platform With Lambda Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller designs for carrying multiple children are either too long, wide, and heavy, making them difficult to maneuver and store, and lack modularity to accommodate varying numbers of children or additional items.
Innovation Solution
A modular stroller frame with multiple sets of mounting points in a 'lambda' configuration allows for the attachment of multiple seats or accessories like a wagon, maintaining stability and maneuverability while enabling customization and efficient storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple carriers are positioned in fore-aft orientation, then the stroller can carry two or more children, but the stroller becomes extremely long, sacrificing the ability to steer effectively
Solution Approach 1:
The patent transitions from linear fore-aft arrangement to a compact configuration where carriers are positioned closer together in a more space-efficient layout, effectively utilizing vertical and lateral dimensions to reduce overall length while maintaining capacity
2Quantity of substance
If multiple carriers are positioned in side-by-side orientation, then the stroller can carry two or more children, but the stroller becomes very wide, complicating passage through doorways and other narrow spaces
Solution Approach 1:
The patent repositions carriers to utilize the vertical dimension and compact lateral spacing, moving away from wide side-by-side arrangement to a configuration that fits through standard doorways while still accommodating multiple children
3Quantity of substance
If the stroller is designed to accommodate multiple children, then the carrying capacity increases, but the stroller becomes large and heavy, making storage and transport difficult
Solution Approach 1:
The stroller is divided into modular components including removable carriers and a base frame, allowing users to configure the stroller for the exact number of children needed, thereby reducing weight when carrying fewer children while maintaining high capacity when needed
4Ease of operation
If the stroller is designed with a fixed configuration for a small number of seats, then the handling and stability are preserved, but the stroller cannot accommodate varying numbers of children or additional items
Solution Approach 1:
The stroller frame includes multiple mounting points distributed throughout the structure, allowing carriers to be attached at different locations and configurations, enabling users to adapt the stroller to carry one, two, or three children plus additional items while maintaining stable weight distribution
Solution Approach 2:
The stroller frame is designed as a universal platform that can accommodate various carrier types and configurations through multiple mounting points, serving multiple functions including carrying children of different ages, transporting additional items, and adapting to different usage scenarios

AI summary
The present invention is a modular stroller platform for carrying multiple small children. The invention enables secure mounting of three seats or carriers in a compact arrangement, giving each child sufficient space without making the stroller unnecessarily difficult to move. Because of its modular design, other accessories, including a wagon body, may be mounted in place of the seats.
