Stroller Frame Hidable Release Actuator Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foldable stroller frames pose a risk of accidental collapsing due to the proximity of the locking and release mechanisms, which can lead to improper folding and endanger the baby occupant, especially for caregivers unfamiliar with the operation procedures.
Innovation Solution
A stroller frame design featuring a hidable release actuator where the release mechanism is mounted on the foldable frame and can be accessed only when the baby carrier is converted into a folded position, preventing accidental activation before the baby is securely held.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the release mechanism is mounted on the handgrip at the same position as the locking mechanism, then the operation is convenient and accessible, but the risk of accidental folding increases and safety deteriorates
Solution Approach 1:
The release actuator is extracted from the handgrip area and relocated to the baby carrier assembly. This spatial separation ensures that the release mechanism is no longer accessible when the stroller is in normal use, eliminating the risk of accidental activation while maintaining operational functionality when properly needed.
Solution Approach 2:
The baby carrier assembly serves as an intermediary structure that houses the release actuator. This intermediary placement creates a conditional access scenario where the release mechanism is only accessible when the carrier is removed or folded, providing a safety buffer between the user and the release function.
2Reliability
If the release actuator is hidden under the baby carrier, then safety against accidental folding is improved, but the complexity of accessing the release mechanism increases
Solution Approach 1:
The access to the release actuator is made dynamic rather than static. The actuator becomes accessible through a dynamic process of folding or removing the baby carrier, transforming a potentially complex access procedure into a natural, flow-based operation that occurs during normal stroller setup and breakdown.
Solution Approach 2:
The design requires preliminary action (folding or removing the carrier) before accessing the release mechanism. This preliminary step serves as a safety checkpoint, ensuring that the user is intentionally preparing to fold the stroller before gaining access to the release actuator, thereby preventing accidental activation.

AI summary
A stroller frame with a hidable release actuator includes a foldable frame, a locking mechanism, a release mechanism and a baby carrier. The locking mechanism is mounted on the foldable frame for locking the foldable frame in the erected configuration. The release mechanism has a release actuator operatively mounted on the foldable frame for unlocking the locking mechanism by rotation in either a forward direction or a rearward direction. The baby carrier has a deployed position to support a baby occupant thereon and can hide the release actuator thereunder. The baby carrier can be converted into a folded position to permit the access to the release actuator. By this arrangement, to prevent the caregiver from accessing the release actuator, so as to avoid accidentally folding of the foldable frame before the baby occupant being held up from the baby carrier.
