Stroller Safety Mechanism Preventing Accidental Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers can accidentally fold or collapse with a child still seated, posing a safety risk, and often require the seat to be removed or reoriented for folding, which is inconvenient.
Innovation Solution
A stroller design featuring a seat with a pivotable back and base, equipped with stops that prevent accidental folding by requiring the seat to be pivoted towards the base before collapsing, allowing the stroller to transition between deployed and collapsed states without removing the seat or changing its orientation, and incorporating handle adjustment mechanisms for safe folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stroller folding mechanisms are used, then the stroller can be collapsed for storage, but the stroller may accidentally fold with a child still seated, causing safety hazards
Solution Approach 1:
The stroller requires the seat to be preliminarily positioned in a folded configuration before the frame can be collapsed. The stops prevent frame folding unless the seat is already in the correct position, ensuring that a child cannot be trapped during accidental folding while still allowing convenient intentional folding when the seat is empty.
2Ease of operation
If the seat is removed or reoriented before folding, then the stroller can be collapsed, but this adds complexity and inconvenience to the folding process
Solution Approach 1:
The stroller's folding mechanism automatically checks whether the seat is in the correct position through the stop arrangement. The system self-regulates by preventing frame folding when the seat is not properly positioned, eliminating the need for users to manually remove or reorient the seat before collapsing the frame.
3Reliability
If the stroller allows free folding, then it can be quickly collapsed, but it cannot prevent accidental folding with a child seated
Solution Approach 1:
The stroller requires the seat to be preliminarily folded before the frame can be collapsed. This preliminary action ensures safety by preventing accidental folding with a child seated, while still allowing rapid intentional folding when the seat is already in the correct position and empty.

AI summary
Disclosed is a stroller (1) moveable between a fully deployed state and a fully collapsed state. The stroller (1) comprises: a seat (2) comprising a seat back (5) pivotably connected to a seat base (6), and one or more stops arranged to prevent the stroller (1) from moving from its fully deployed state to its fully collapsed state, wherein the one or more stops arranged to be released to permit the stroller (1) to move from its fully deployed state to its fully collapsed state when at least one of the seat base (6) and seat back (5) is pivoted towards the other. The stroller provides improved safety.
