Vertically Movable Stroller Frame with Rail System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers are limited in space, making it inconvenient for babies and toddlers to enter and exit, and they primarily serve a single function of sitting or sleeping without accommodating vertical movement or multi-functional use.
Innovation Solution
A vertically-movable, transmission-friendly, and controllable stroller design featuring a rail system with a collapsible frame, engaging elements, and gear mechanisms that allow the stroller to transform into a seat or sofa, enabling easy entry and exit through vertical movement and multi-segment adjustment of the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stroller uses a fixed frame structure, then it provides stable support for the child, but it limits space and makes it inconvenient for babies and toddlers to enter and exit
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed frame structure into a vertically movable one. The frame can switch between an expanded configuration (providing stable stroller support) and a collapsed configuration (creating open access for entry/exit). This is achieved through movable connections between frame components that allow vertical translation while maintaining structural integrity in both states.
2Adaptability or versatility
If the stroller is designed for single function (sitting or sleeping), then it simplifies the structure, but it cannot accommodate vertical movement or multi-functional use
Solution Approach 1:
The patent implements universality by designing the frame to perform multiple functions: it serves as a stable support structure when expanded for stroller use, and transforms into a collapsed configuration that enables easy entry/exit or conversion to seating arrangements. The same frame components serve both the stroller function and the access/function transformation function.
Solution Approach 2:
The dynamic transformation capability allows the frame to adapt between different functional states (expanded stroller mode vs. collapsed access mode), enabling multi-functionality without requiring completely separate structures for each function.
3Ease of operation
If the locking mechanism requires two-person operation, then it ensures safety, but it reduces convenience for single-person use
Solution Approach 1:
The patent merges the locking and unlocking operations into a single integrated mechanism. The locking element is positioned and configured so that one person can simultaneously engage both locking actions required for safe frame transformation, eliminating the need for two-person operation while maintaining safety through the interlocked nature of the locking system.

AI summary
A vertically-movable, transmission-friendly, and controllable stroller includes a front wheel component, rear wheel component, frame, and rail component. The front wheel component includes a front wheel hanger, front lateral right and left wheels mounted on the bottom of the front wheel hanger. The rear wheel component includes a rear wheel hanger, rear lateral right and left wheels mounted on the bottom of the rear wheel hanger. The frame includes front, rear, right and left lateral subframes. The front lateral subframe has a bottom pivotally connected to the front wheel component. The rear lateral subframe has a bottom pivotally connected to the rear wheel component. The rail component includes front and rear right rails disposed on front and rear right lateral upright tubes respectively, allowing left and right ends of a right lateral top tube to be vertically slidingly connect between the front and rear right lateral upright tubes.
