Compact Foldable Stroller Frame for Multi-Mode Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers often lack the ability to fold compactly while maintaining multiple seating modes and suitable wheel configurations for uneven terrain, limiting their adaptability and storage efficiency.
Innovation Solution
A collapsible stroller frame with a series of connections, linkages, and a basket assembly that can be folded into a compact size, along with an adaptor assembly for child carriers, allowing for multiple seating configurations and secure attachment of infant carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stroller is designed to be collapsible for compact storage and transportation, then the folded size is reduced, but the available features and seating configurations are limited
Solution Approach 1:
The stroller frame is divided into multiple collapsible sections including the handle portion, front leg portion, and rear leg portion that can fold independently. The seat mount is also segmented with guide links that allow it to fold with the frame while maintaining functionality. This segmentation enables compact folding while preserving all seating configurations when unfolded.
Solution Approach 2:
The stroller employs dynamic linkages and guide links that allow the seat mount to maintain its functional position during folding and unfolding operations. The basket assembly uses guide links to dynamically adjust its position as the frame collapses, ensuring that all features remain accessible and functional in both folded and unfolded states.
2Quantity of substance
If the stroller includes a basket assembly for storage, then storage capacity is improved, but the folded size increases
Solution Approach 1:
The basket assembly is designed to nest within the stroller frame structure when folded. The guide links allow the basket to collapse inward and occupy the same spatial envelope as the frame components, effectively reducing the overall folded volume while maintaining full storage capacity when unfolded.
Solution Approach 2:
The basket assembly uses dynamic guide links that enable it to transition between an extended storage position and a compact folded position. The guide links facilitate smooth movement and positioning of the basket during folding operations, allowing it to integrate seamlessly with the collapsed frame structure.
3Adaptability or versatility
If the stroller is designed with multiple seating modes, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The stroller frame is designed as a universal platform that supports multiple seating configurations through a single integrated seat mount system. The guide links and linkage connectors enable the same frame structure to accommodate various seat types and positions without requiring additional complex mechanisms, achieving multi-functionality through elegant mechanical design.
Solution Approach 2:
The guide links serve as intermediary components that mediate between the frame structure and the seat mount, enabling multiple seating configurations without directly complicating the frame. These intermediary elements provide the necessary degrees of freedom and guidance for various seat positions while maintaining a relatively simple overall frame design.
