Stroller Safety Lock Mechanism Preventing Accidental Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers lack a safety mechanism to prevent accidental folding, which can lead to unintentional movement and potential hazards when the folding handle is operated by children or caregivers.
Innovation Solution
A safety lock system that includes a releasing component and a locking component, where the locking component moves between a blocking and a releasing position, engaging or disengaging with the stroller frame or frame releasing component to prevent or allow folding, utilizing resilient components and driving profiles to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stroller frame is made foldable for easy transportation and storage, then the flexibility and space efficiency are improved, but the risk of accidental folding by children or caregivers increases
Solution Approach 1:
The safety lock acts as an intermediary component between the frame releasing component and the locking device. It includes a locking component that can engage with the frame releasing component to block its movement, preventing accidental unlocking. The safety lock mediates the interaction between the folding mechanism and external forces, allowing intentional folding by caregivers while blocking unintentional folding by children.
Solution Approach 2:
The safety lock applies preliminary anti-action by positioning the locking component in a default engaged state that prevents the frame releasing component from moving. This preliminary blocking action counteracts potential accidental forces before they can trigger unwanted folding. The resilient component maintains this preliminary anti-action through continuous elastic force on the locking component.
2Object-affected harmful factors
If a safety lock mechanism is added to prevent accidental folding, then the safety is improved, but the device complexity increases
Solution Approach 1:
The safety lock is segmented into distinct functional components: a locking component for blocking/unblocking the frame releasing component, and a resilient component for providing restoring force. This segmentation allows each component to perform its specific function simply, while the overall system remains relatively straightforward. The locking component can be a simple movable element that engages or disengages from the frame releasing component.
Solution Approach 2:
The resilient component provides self-service by automatically restoring the locking component to its default engaged position after being displaced. This eliminates the need for complex control systems or additional actuators to reset the safety lock. The resilient component continuously maintains the safety function through its elastic properties, reducing the need for active control mechanisms.

AI summary
A safety lock includes a releasing component and a locking component. The locking component is movably disposed on a frame releasing component or a stroller frame. The locking component is driven by the releasing component to move relative to the frame releasing component or the stroller frame between a blocking position and a releasing position. The locking component engages with the frame releasing component to restrain the frame releasing component from unlocking the stroller frame or engages with the stroller frame to restrain the stroller frame from being folded when the locking component is located at the blocking position, and the locking component disengages from the frame releasing component to allow the frame releasing component to unlock the stroller frame or disengages from the stroller frame to allow the stroller frame to be folded when the locking component is located at the releasing position.
