Rotatable Child Seat Release Latch for Secure Base Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child restraints lack a convenient and secure mechanism for removably attaching and detaching a juvenile seat from a seat base, particularly in various orientations, which complicates transportation and installation.
Innovation Solution
A child restraint system featuring a juvenile-seat release system with an attachment post, retainer latch, and release actuator that allows the juvenile seat to be securely mounted and easily separated from the seat base, and includes a retainer system to block removal in forward and rearward-facing orientations, enabling rotation and secure attachment in different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a juvenile seat is permanently fixed to a seat base, then the child's safety during transportation is ensured, but the ease of operation for installation and removal is worsened
Solution Approach 1:
The child restraint system is divided into two separable components: a seat base and a juvenile seat. The juvenile seat can be detached from the seat base when not in use, while the seat base remains installed in the vehicle. This segmentation allows the safety features of the seat base to be retained while improving ease of operation by enabling simple removal of the juvenile seat component.
2Ease of operation
If a juvenile seat is made removable from a seat base, then the ease of operation for installation and removal is improved, but the reliability of child safety is worsened
Solution Approach 1:
The retention system incorporates automatic engagement features where the juvenile seat self-locks to the seat base upon proper installation. The retainer mechanism automatically engages with the attachment post when the juvenile seat is positioned correctly, providing reliable safety without requiring complex manual locking procedures. This self-service approach maintains safety while preserving ease of operation.
3Reliability
If a complex retention system is used to secure the juvenile seat in multiple orientations, then the reliability is improved, but the device complexity is worsened
Solution Approach 1:
The attachment post and retainer mechanism are designed as universal components that function across multiple orientations (forward-facing, rearward-facing, and sideways). The retainer latch and release actuator system provides a single unified retention mechanism that adapts to different installation orientations without requiring separate complex systems for each orientation, thereby improving reliability while controlling device complexity.

AI summary
A child restraint includes a seat base adapted to rest on a vehicle seat and a juvenile seat coupled to the seat base. The child restraint further includes a juvenile-seat release system configured to mount the juvenile seat to the seat base and allow separation of the juvenile seat from the seat base.
