Movable ISOFIX Connecting Assembly for Lowering Baby Seat Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby safety seats with ISOFIX connectors are rigidly connected to the car, making it difficult to lower the seat body, increasing the risk of the baby's head colliding with the car roof during seating.
Innovation Solution
A connecting assembly with a movably connected ISOFIX connector that allows flexible adjustment of the seat body height, featuring a pivotally connected frame and a locking mechanism to enable the connector to move between work and reset positions, allowing the seat body to descend relative to the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ISOFIX connector is fixedly connected with the seat body (hard connection), then the connection structure is simple and stable, but the seat body cannot be lowered after connection, resulting in increased overall height and higher risk of baby's head colliding with the car roof
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid fixed connection into a movable connection. The ISOFIX connector is connected to the seat body through a movable connection mechanism that allows the connector to move relative to the seat body along the height direction. This enables the seat body to lower automatically after connection while maintaining a stable connection structure, thus resolving the contradiction between connection stability and head collision risk.
2Device complexity
If the ISOFIX connector is fixedly connected with the seat body, then the structural complexity is low, but the adaptability to different seating conditions is reduced
Solution Approach 1:
The movable connection mechanism introduces dynamic adjustment capability without significantly increasing structural complexity. The connector can move along the height direction to adapt to different seating conditions and baby sizes, providing versatility while maintaining a relatively simple connection structure.
Solution Approach 2:
The connection system is segmented into movable components (connector, seat body, and connection mechanism) that can move independently. This segmentation allows the connector to adjust its position relative to the seat body, providing adaptability to different conditions while keeping each component relatively simple in structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the baby's head from colliding with the car roof by allowing the seat body to move downwards under gravity, providing enhanced safety and protection.
Implementation Method 1
the connecting assembly further includes an elastic member, one end of the elastic member is connected with the connector, the other end of the elastic member is connected with the frame body
Implementation Method 2
the connector is pivotally connected with the frame body through the pivot shaft
Implementation Method 3
the seat body, to which the frame body is connected, is allowed to move downwards relative to the connector

AI summary
The present disclosure provides a connecting assembly including a frame body for connecting with a seat body and a connector for connecting with a car seat. The connector is movably connected with the frame body, and the connector is movable relative to the frame body such that the connector has a work position and a reset position. The connector angles with the frame body when the connector is in the work position, while the connector flushes with the frame body when the connector is in the reset position. By virtue of the motion of the connector relative to the frame body between the work position and the reset position, the seat body, to which the frame body is connected, is allowed to move downwards relative to the connector. The present disclosure further provides a baby carriage frame having the connecting assembly.
