Infant Carrier One-Hand Release for Quiet Seat-to-Stroller Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional baby strollers require the installation and removal of an armrest to connect and disconnect safety seats, which complicates folding and storage, and can disturb sleeping babies during transfer.
Innovation Solution
A baby carrier with a pair of connecting plugs and a one-hand release actuator that allows secure locking and unlocking with a stroller or car seat without the need for an armrest, featuring a latch member and safety lock for safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an armrest is installed to connect the safety seat to the stroller, then the connection reliability is improved, but the device complexity increases and the ease of operation deteriorates due to the need to install and uninstall the armrest
Solution Approach 1:
The invention extracts the connection function from the armrest structure and integrates it directly into the stroller frame through sockets. This eliminates the need for a separate armrest component while maintaining the connection reliability, thereby reducing device complexity and improving ease of operation.
Solution Approach 2:
The stroller frame is designed with universal sockets that can directly receive connecting plugs from safety seats without requiring additional armrest structures. This multi-functional design allows the stroller to maintain connection capability while simplifying the overall structure and enabling one-handed operation.
2Reliability
If an armrest is used for connecting the safety seat, then the connection reliability is improved, but the ease of operation worsens due to the troublesome installation and uninstallation process
Solution Approach 1:
The connection function is extracted from the armrest and integrated into the stroller frame sockets. This allows direct connection of the safety seat to the stroller frame without needing to attach or detach an armrest, significantly improving ease of operation while maintaining connection reliability through the socket-plug locking mechanism.
Solution Approach 2:
The connecting plug incorporates a one-handed release actuator that allows the user to easily unlock and detach the safety seat from the stroller by simply pressing the actuator. This self-service mechanism improves ease of operation while maintaining reliable connection during use through the latch member and socket engagement.
3Reliability
If the safety seat is connected to the stroller armrest, then the connection reliability is improved, but the productivity deteriorates due to the time required to install and uninstall the armrest
Solution Approach 1:
The connection function is extracted from the armrest structure and built into the stroller frame as fixed sockets. This eliminates the time-consuming process of installing and uninstalling armrests, allowing direct connection and disconnection of the safety seat, thereby improving transfer efficiency while maintaining connection reliability through the socket-plug locking mechanism.
Solution Approach 2:
The one-handed release actuator enables quick and easy detachment of the safety seat from the stroller by simply pressing the actuator to release the latch member. This self-service mechanism significantly reduces the time required for transfer operations while maintaining reliable connection during use, thereby improving productivity.
4Ease of operation
If the connecting plug uses a latch member that extends outwardly, then the ease of operation is improved for one-handed release, but the reliability may worsen due to potential accidental disengagement
Solution Approach 1:
The connecting plug incorporates a safety lock that must be deliberately actuated to release the latch member. This preliminary anti-action prevents accidental disengagement by requiring a conscious action to override the locked position, while still allowing easy one-handed release when intentionally activated by the user.
Solution Approach 2:
The connecting plug provides tactile feedback through the safety lock mechanism that indicates whether the connection is locked or unlocked. This feedback mechanism helps the user understand the connection state and prevents accidental disengagement by requiring deliberate action to change the state, thereby improving reliability while maintaining ease of operation.

AI summary
A baby carrier has a pair of connecting plugs (4), a handle (11) and a one-hand release actuator (3), providing a convenience for hand carrying a baby and transferring the baby between some transporting devices, such as a car, a safety seat, a wheeled rack and a baby stroller without pulling up the baby therefrom. The baby transporting device has a pair of sockets (21) mounted on both sides thereof for lockably and unlockably connecting with the pair of connecting plugs. The connecting plugs each has at least a latch member associated with the one-hand release actuator (3) and extends outwardly to lock the connecting plugs in the sockets, and unlock the connecting plugs from the sockets by griping the one-hand release actuator with one hand of the user.
