Foldable Stroller with Integrated Bassinet Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable strollers and bassinets require separate operations to fold, which can be cumbersome and inconvenient, especially when carrying an infant, as they need to remove and fold the bassinet or seat separately from the chassis, complicating the folding process.
Innovation Solution
A foldable stroller and bassinet design that allows for a single, integrated folding process, where the wheeled chassis and bassinet can be folded together without removing the bassinet from the chassis, using a telescopic handle and locking mechanisms to facilitate a compact and convenient folding mechanism that can be performed with one hand, enabling the stroller to be folded into a compact condition without separate operations for the chassis and bassinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate folding operations are used for bassinet and chassis, then structural stability is maintained, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines the bassinet folding mechanism with the chassis folding mechanism into a single integrated system. When the chassis is folded, the bassinet automatically folds along with it through connected folding joints, eliminating the need for separate folding operations and reducing user effort while maintaining structural stability
Solution Approach 2:
The bassinet is designed to nest within or alongside the chassis structure during folding. The bassinet folding joints are integrated with the chassis folding joints, allowing the bassinet to be contained within the overall folding motion of the stroller, creating a compact nested configuration when folded
2Loss of time
If bassinet is removed from chassis for folding, then folding simplicity improves, but operational time increases and user convenience deteriorates
Solution Approach 1:
The patent merges the bassinet attachment to the chassis through integrated folding joints that allow both components to fold simultaneously. This eliminates the time-consuming removal and separate folding operations, reducing total folding time while maintaining ease of operation through a single unified folding action
3Productivity
If integrated folding is implemented, then user convenience improves and folding time reduces, but structural complexity increases
Solution Approach 1:
The integrated folding mechanism is designed to be self-regulating through interconnected folding joints and automatic locking features. When the chassis folds, the bassinet folding joints automatically engage and lock through the same motion, eliminating the need for separate locking operations and reducing overall mechanism complexity while improving folding efficiency
