Removable Stroller Seat Connectors for Versatile Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Strollers often become non-functional when a second seat is no longer needed, as they are designed for either a single child or twins, lacking versatility for changing passenger requirements.
Innovation Solution
A stroller system with a removably attached seat system that includes adjustable connectors and supports, allowing additional seating capacity and adaptability to various stroller frames, enabling flexible seating configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stroller is designed with a fixed single seat configuration, then the structure is simple and easy to manufacture, but it cannot accommodate multiple children when needed
Solution Approach 1:
The seat system transitions from a static fixed configuration to a dynamic removable configuration. The seat assembly can be attached to or detached from the stroller frame based on need, allowing the stroller to adapt between single-child and multi-child configurations. This dynamic attachment mechanism resolves the contradiction by enabling versatility without permanently increasing structural complexity.
Solution Approach 2:
The seat system is divided into separate modular components: the stroller frame and the removable seat assembly. This segmentation allows the seat capacity to be independently adjusted by adding or removing seat modules, providing adaptability while keeping the base frame simple and easy to manufacture.
2Adaptability or versatility
If a stroller is designed with a fixed twin seat configuration, then it can transport two children simultaneously, but it becomes non-functional or inefficient when only one child needs transport
Solution Approach 1:
The seat system allows dynamic adjustment of seating capacity by removing unnecessary seat modules. When only one child needs transport, the second seat can be detached, reducing the overall weight of the moving object to match the actual load requirement, thus resolving the contradiction between adaptability and weight.
3Adaptability or versatility
If a stroller is designed with a fixed single seat configuration, then the weight is minimized for single child transport, but it cannot provide additional seating when needed
Solution Approach 1:
The seat system is segmented into a simple base frame and separate removable seat modules. This segmentation maintains manufacturing simplicity for the base frame while enabling adaptability through the addition of standardized seat modules that can be attached to pre-defined attachment points on the frame.
Solution Approach 2:
The stroller frame is designed with universal attachment features that can accommodate different seat configurations. The same frame structure supports both single-seat and multi-seat arrangements, providing multi-functionality without requiring different frame designs for different seating capacities.

AI summary
A stroller system (10) includes a stroller frame (100) and a seat system (200). The stroller frame includes first and second frame supports (110, 120) spaced apart from each other, at least one third frame support (150, 160) attaching the first frame support to the second frame support, and wheels (170). The seat system is removably attached to the stroller frame and includes a seat support (210) having first and second end portions (212, 214), and first and second end connectors (302, 304) disposed on the corresponding first and second end portions of the seat support. Each end connector includes a connector body (310) having first and second end portions (312, 314), where each end portion defines a recess (316, 318) configured to receive one of the frame supports. The recesses arranged substantially in opposition to engage the received support in substantially opposing directions.
