Stroller with Expandable Base and Independent Folding Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers lack the capacity to simultaneously carry multiple children and provide an extendable cargo area, with most designs either compromising on passenger capacity or storage space, and often featuring complex and inflexible deployment mechanisms that hinder easy expansion and compact folding.
Innovation Solution
A stroller design featuring an expandable base member with pivotally connected frame members that can fold independently, allowing for the inclusion of a second seat and an extendable cargo area, which can be easily deployed and compactly folded using actuation mechanisms and locking systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stroller size is reduced for easier storage, then storage ease is improved, but cargo capacity and passenger capacity deteriorate
Solution Approach 1:
The stroller is divided into modular components including a base unit, an expandable cargo area that can be added or removed, and independently foldable frame members. This segmentation allows the stroller to be configured in different states (compact vs. expanded) to balance storage ease with cargo capacity based on user needs.
2Ease of operation
If the stroller size is reduced for easier storage, then storage ease is improved, but passenger capacity deteriorates
Solution Approach 1:
The frame members are designed to be dynamically foldable and reconfigurable, allowing the stroller to transition between a compact single-passenger configuration and an expanded multi-passenger configuration. This dynamic structure enables the stroller to adapt its passenger capacity based on whether it needs to be stored or used with multiple children.
3Quantity of substance
If an expandable cargo area is added to increase storage space, then cargo capacity is improved, but device complexity increases
Solution Approach 1:
The expandable cargo area is merged with the base stroller frame through integrated connection mechanisms, allowing the cargo area to expand and contract as part of the overall stroller structure rather than as a separate附加 component. This merging reduces the number of separate parts and simplifies the deployment process.
4Ease of operation
If independent folding mechanisms are added to frame members for compact folding, then storage ease is improved, but device complexity increases
Solution Approach 1:
The frame is segmented into multiple independently foldable members (first frame member, second frame member, third frame member) that can be folded separately. This segmentation allows each member to be collapsed independently, achieving compact storage without requiring a complex unified folding mechanism for the entire frame structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the stroller to carry multiple passengers while providing ample storage space, with the ability to handle heavy loads and fold into a compact state for easy storage and travel, addressing the limitations of previous stroller designs.
Implementation Method 1
A first frame member may be pivotally connected to the expandable base member near the first peripheral end. A second frame member comprising at least one frame mount hub may also be pivotally connected to the expandable base member near the second peripheral end.

AI summary
A stroller system including an expandable base and two frame members is discussed. The stroller system is configured for dual occupancy and provides an expandable cargo area to a user. The first and second seats coupled to their respective frame members may be modular in nature. The second seat may also include a bench seat with optional secondary support structures. The two frame members are configured to fold independently of one another. The mechanical apparatus of the dual occupancy stroller including locking and actuator mechanisms are discussed. Additionally, the mechanism by which the front frame member folds is discussed.The disclosed stroller is capable of simultaneously carrying multiple children with a cargo area that can be extended or retracted and can carry a heavy load. The stroller is able to easily fold to a stowed state.
