X-Frame Stroller Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor strollers for children have limited space, making them unsuitable for use as playpens, and their complex folding mechanisms are cumbersome for caretakers, requiring the purchase of separate strollers and playpens, increasing costs and operational difficulty.
Innovation Solution
An outdoor stroller design featuring X-shaped crossbars and a disengaging mechanism with a clamping device allows for easy unfolding and folding, enabling the stroller to be used as both a stroller and playpen, with a large interior space, and simplifies the operation by using a pull handle to fold and unfold the stroller without complicated structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional stroller is designed with a compact folding structure, then it is easy to carry and store, but the sitting space for the child becomes small and it cannot be used as a playpen
Solution Approach 1:
The stroller frame is segmented into multiple collapsible sections including telescopic handlebars and foldable leg rests, allowing the structure to be divided into compact segments when folded while maintaining adequate space when unfolded
Solution Approach 2:
The stroller employs dynamic folding mechanisms with movable joints and telescopic components that allow the frame to transition between expanded and compact states, enabling adequate sitting space during use while achieving compact dimensions for storage
2Adaptability or versatility
If separate stroller and playpen apparatuses are purchased to meet different needs, then both functions are available, but the cost increases and the caretaker is exhausted from constantly unfolding and folding two different apparatuses
Solution Approach 1:
The stroller is designed as a multi-functional apparatus that can operate as both a compact stroller for transportation and an expanded playpen for stationary use, eliminating the need for separate devices and reducing the complexity of managing multiple folding structures
3Ease of operation
If a conventional stroller uses a complicated folding structure to enable folding, then it can be collapsed for carrying, but the operation becomes cumbersome and annoying for the caretaker
Solution Approach 1:
The stroller incorporates self-latching mechanisms and automatic locking features that enable the folding structure to secure itself during collapse and expansion, reducing the complexity of manual operation while maintaining ease of use for the caretaker

AI summary
An outdoor stroller for children is disclosed, including a top frame and a bottom frame which are frame units parallel to each other. An upper lateral bar is pivoted with a lower lateral bar which is crossed over and put upright with a crossbar in an X-shape. By the arrestment of a disengaging mechanism and a clamping device, the upper lateral bar and the lower lateral bar are formed into a straight bar to support and level the top frame parallel, thereby unfolding the stroller. On the other hand, the upper lateral bar and the lower lateral bar are turned backward, the top frame is lowered down parallel, and the lower lateral bar and the crossbar that are crossed over in the X-shape are folded with each other, so as to fold the stroller.
