Modular Stroller Seat Modules with Integral Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers lack a compact and efficient design for shipping and assembly, and often fail to provide a rigid structure capable of safely supporting multiple children, while also offering adequate safety restraints and versatility for accommodating additional passengers.
Innovation Solution
A stroller assembly featuring a frame with integral plastic seat modules that interlock via projections and slots, allowing for disassembly into a single shipping box, and accommodating additional modules for increased capacity, along with safety features like child restraints and a roof for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If stroller components are designed to be disassembled for compact shipping, then shipping efficiency and storage space are improved, but assembly complexity and structural rigidity may deteriorate
Solution Approach 1:
The stroller is divided into separate modular components including seat modules, wheel assemblies, and frame sections that can be disassembled for compact shipping. Each module is designed with standardized connection interfaces that ensure rigid assembly when put together, resolving the contradiction between compact shipping volume and structural rigidity.
Solution Approach 2:
Components are designed to nest within each other during shipping - wheel assemblies nest within frame sections, and seat modules nest within each other or within the frame structure. This nesting arrangement minimizes shipping box volume while maintaining the integrity and rigidity of individual components for safe assembly.
2Adaptability or versatility
If multiple seat modules are integrated to increase passenger capacity, then versatility and load capacity are improved, but device complexity and safety restraint reliability may worsen
Solution Approach 1:
The stroller employs universal connection interfaces and standardized fastening mechanisms that work across all seat modules and configurations. This allows the system to accommodate one, two, or four children using the same basic connection system, increasing versatility without proportionally increasing complexity.
Solution Approach 2:
The seating system is segmented into independent, identical modules that can be assembled in series. Each module contains its own integrated safety restraints and connection points, allowing complex multi-child configurations to be built from simple, standardized units, thereby managing overall system complexity.
3Strength
If integral fastener members are used to connect seat modules, then structural rigidity and safety are improved, but manufacturing complexity and cost may worsen
Solution Approach 1:
The fastener members are integrally formed as part of the seat module structures rather than being separate components. This merging of fastening functions into the seat modules themselves simplifies the overall part count and assembly steps while maintaining strong, reliable connections between modules.
Solution Approach 2:
The seat modules and fastener members are constructed from molded plastic materials that provide both structural integrity and connection functionality. This use of composite plastic construction allows integral fasteners to be formed directly during molding, reducing manufacturing complexity while ensuring adequate connection strength.

AI summary
A stroller assembly is provided that includes a frame. The stroller assembly may also include a plurality of wheel assemblies that are operable to mount to the frame. In addition, the stroller assembly may include a front seat module and a back seat module comprised of a plastic material. The front seat module and the back seat module may include integral fastener members that are operative to engage with each other when the front seat module and the back seat module are mounted to the frame.
