Collapsible Stroller with Expandable Base Frame and Adapter Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current double strollers have a larger footprint than single strollers, making them difficult to maneuver in confined spaces, and existing strollers often have complex folding mechanisms and misplaced adapters.
Innovation Solution
A collapsible and convertible stroller with an expandable base frame, allowing the front wheel assembly to move relative to the rear wheel assembly, and a lock/unlock mechanism for easy deployment and storage, along with a purpose-built storage compartment for adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stroller is designed with a fixed double occupancy footprint, then it can accommodate two occupants, but it becomes difficult to maneuver in confined spaces
Solution Approach 1:
The stroller employs a dynamic base frame with movable front wheel assembly that can transition between retracted and extended positions. The base frame includes movable members that allow the front wheel assembly to be retracted for compact single-occupancy maneuverability and extended for stable double-occupancy configuration, resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The stroller is divided into separable modules including a detachable front wheel assembly, movable base frame members, and independent seat units. This segmentation allows the stroller to be reconfigured between single and double occupancy modes by detaching or repositioning modules, enabling both compact maneuverability and expanded capacity
2Device complexity
If the stroller uses complex folding mechanisms for collapse, then it can be folded, but it becomes difficult to collapse and deploy
Solution Approach 1:
The stroller incorporates self-latching folding mechanisms where moving base frame members automatically engage with locking members to secure the folded position. The design includes gravity-assisted folding where the structure naturally collapses into position and locks without requiring complex manual operations, simplifying the collapse and deploy process
Solution Approach 2:
The folding mechanism is simplified by extracting complex multi-step locking systems and replacing them with straightforward latch-based mechanisms. The base frame members are designed with integrated locking features that engage automatically during folding, removing the need for complicated manual folding procedures
3Ease of operation
If adapters are stored externally on the stroller, then they are accessible, but they can be lost or misplaced during storage and transportation
Solution Approach 1:
The adapter storage system uses a nested design where adapters are housed within a protective compartment integrated into the stroller frame. The compartment is accessible during use but secured during storage and transportation, preventing adapter loss while maintaining accessibility when needed

AI summary
A purpose-built storage compartment of a stroller includes a compartment housing configured to be fitted into a selected position of a stroller, a cover, and a pair of adapters configured to pivotally connect with the compartment housing and be movable between a storage position inside the compartment housing and a deployed position to engage with a detachable apparatus.
