Rotatable Child Seat Base With Locking Recess and Tilt Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child restraint systems are cumbersome to use and lack improved safety features.
Innovation Solution
A base for child restraint systems with a primary support portion that allows positive locking and angular orientation of child seats, featuring a cone-like appearance with a circumferential recess for easy coupling and a secondary support portion for enhanced stability, along with a tensioning mechanism for secure installation on vehicle seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional child restraint system is used, then the child seat can be mounted on the vehicle seat, but the system is cumbersome to use and lacks improved safety features
Solution Approach 1:
The base is divided into functionally distinct portions: a primary support portion for receiving and rotatably supporting the child seat, and a secondary support portion for providing additional stability and limiting tilting movements. This segmentation allows each portion to be optimized for its specific function, improving ease of operation while maintaining manageable complexity through clear functional division.
2Adaptability or versatility
If the child seat is made rotatable about the rotation axis, then the user can adjust the orientation, but the stability and safety may be compromised
Solution Approach 1:
The system transitions from a static mounting to a dynamic one: the child seat can rotate about the rotation axis between different orientations (forward-facing, rearward-facing, side-facing) while maintaining secure engagement. The primary support portion enables this dynamic adjustment, and the secondary support portion ensures stability is maintained throughout the range of motion.
Solution Approach 2:
The secondary support portion is pre-configured to limit tilting movements and provide stability before the child seat is fully installed or rotated. This preliminary stabilization ensures that even during rotational adjustment, the system maintains adequate stability and safety.
3Ease of operation
If the primary support portion allows coupling in multiple arbitrary angular positions, then the ease of installation is improved, but the precision of positioning may be reduced
Solution Approach 1:
The primary support portion provides an angular dropping zone that exceeds 90° on each lateral side, offering more rotational freedom than strictly necessary for basic installation. This excessive angular range simplifies installation by allowing users to couple the child seat in multiple arbitrary positions, and the system maintains adequate stability throughout this extended range.
