Movable Carrier Linkage for Adjustable Stroller Seating

The patent applies the dynamics principle by transforming the fixed seat structure into a movable one. The carry members are connected to the bottom frame assembly through link assemblies that enable dynamic repositioning. The link assemblies include link members with connect members that can pivot and adjust, allowing the carry members to move between different positions (side-by-side, tandem, angled configurations) while maintaining structural integrity during motion.

The patent applies segmentation by dividing the connection system into multiple independent components: the bottom frame assembly, separate link assemblies for each carry member, link members, connect members, and adapter members. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability, making the complex adjustment mechanism more manageable and maintainable.

The patent applies dynamics by designing the link assemblies and support members to be movable rather than fixed. The link members can pivot and the support members can fold, enabling the stroller to transition between expanded configurations (for carrying infants) and compact folded configurations (for storage). This dynamic design allows the stroller to maintain versatility while reducing storage volume when not in use.

The patent applies the nesting principle through the folding mechanism where the support members fold against the bottom frame assembly, and the link assemblies can be positioned to minimize the overall volume. When folded, the structure consolidates into a more compact form that occupies less storage space while retaining the capability to expand to various seating configurations when needed.

The patent applies dynamics by enabling the carry members to be dynamically repositioned to different orientations and angles. The link assemblies allow the carry members to move not only between side-by-side and tandem positions but also to be angled toward the parent, facilitating direct eye contact and interaction. This dynamic positioning capability enhances parent-baby interaction while using a mechanical linkage system rather than complex electronic actuators.

The patent applies multi-functionality by designing the link assemblies to provide multiple functions: they enable position adjustment, maintain structural support, allow angular adjustment for interaction, and ensure safe movement. This multi-functional design achieves improved parent-baby interaction capabilities without proportionally increasing device complexity, as the same mechanical components serve multiple purposes.
