Infant Stroller with Detachable Seats and Folding Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stroller designs cannot be folded with detachable infant car seats and often fail to accommodate children of older ages, lacking versatility in seating positions.
Innovation Solution
A stroller apparatus with pivotally connected components, including front and rear legs, side handrails, a handle, and a seat support frame, allowing for the detachable assembly of multiple seats at different heights and positions, enabling the stroller to accommodate children of various ages and positions, including forward-facing options, while maintaining the ability to fold without seat disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stroller is designed to detachably receive a portable infant car seat, then it can accommodate infants and provide close caregiver interaction, but it cannot be folded with the detachable seat thereon and may not accommodate children of older ages
Solution Approach 1:
The stroller is designed with a universal seating system that can accommodate multiple types of seats (infant car seats, child seats, booster seats) at different positions (front, rear, side-by-side). The detachable seat assembly mechanism and adjustable seat support frame enable the same stroller structure to serve different age groups and seating configurations, achieving multi-functionality without requiring multiple specialized strollers
Solution Approach 2:
The stroller structure is divided into separable components including detachable seats, adjustable seat support frames, and modular handrail assemblies. This segmentation allows the seat to be independently removed or repositioned, enabling the stroller to be folded with or without seats attached and facilitating easy reconfiguration for different age groups and seating arrangements
2Adaptability or versatility
If a stroller is designed with fixed seating positions, then the structure is simpler, but it cannot accommodate children of various ages and positions
Solution Approach 1:
The stroller employs dynamic seating configurations where seats can be easily detached, repositioned, and reattached to different locations on the stroller frame. The detachable seat assembly mechanism with simple connection interfaces allows caregivers to quickly reconfigure seating arrangements without complex tools or procedures, maintaining ease of operation while achieving high adaptability
Solution Approach 2:
The stroller is designed with pre-configured mounting points and attachment mechanisms at multiple locations (front, rear, side-by-side positions) that are ready for seat installation. This preliminary preparation of mounting structures enables rapid seat reconfiguration without requiring complex assembly steps, making it easy to adapt the stroller for different age groups and seating preferences
