Stroller Chassis Crossbar Mounting for Booster Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible strollers for juveniles lack a stable and easy-to-install solution for accommodating multiple children, often requiring additional connecting elements and compromising on stability and compactness when multiple seats are used.
Innovation Solution
A stroller design featuring a chassis with crossbars that allows for direct and stable mounting of a booster seat at three points, using connecting means such as rings and jaws to secure the seat without intermediary elements, enabling easy installation and removal while maintaining stability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional connecting elements are used to accommodate multiple children, then the stroller can support more children, but the stability and compactness are compromised
Solution Approach 1:
The patent integrates the connecting means directly into the chassis structure, merging the function of seat attachment with the chassis framework. The crossbars and mounting points are built-in structural elements rather than separate accessories, allowing multiple seats to be attached without adding external connecting elements that would compromise stability or compactness.
Solution Approach 2:
The chassis is designed with universal mounting points and crossbars that serve multiple functions: structural support for the stroller frame and attachment points for one or multiple child seats. This multi-functionality allows the same structural elements to accommodate different seating configurations without requiring additional specialized connecting elements.
2Adaptability or versatility
If traditional mounting methods are used for multiple seats, then seats can be attached, but the installation becomes complex requiring additional connecting elements
Solution Approach 1:
The connecting means are merged into the chassis as integral structural elements (crossbars and mounting points) rather than separate components. This integration eliminates the need for additional connecting elements and simplifies the installation process, as seats can be directly attached to the built-in mounting points without assembling separate connecting hardware.
3Adaptability or versatility
If multiple seats are added to the stroller, then more children can be transported, but protruding elements are created that compromise safety
Solution Approach 1:
The mounting points and crossbars are merged into the chassis as integral structural elements that are flush with or recessed into the frame. This integration ensures that no protruding elements extend beyond the stroller's outer轮廓, eliminating safety hazards while maintaining the capacity to securely attach multiple child seats.

AI summary
A stroller includes a chassis and a child support. The chassis is configured to roll along the ground in response to being pushed by a caregiver. The child support is coupled selectively to the chassis and is configured to support a child resting therein.
