Removable Child Seat Support With Reclining Yoke Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child restraints lack a flexible positioning system that allows for easy adjustment between upright and reclined positions, complicating the installation and removal of juvenile vehicle seats, especially when transitioning between front-facing and rear-facing configurations.
Innovation Solution
A child restraint system featuring a seat support with a lower yoke and upper yoke that can move between upright and reclined positions, with the juvenile vehicle seat coupled to both yokes in a front-facing position and only the lower yoke in a rear-facing position, incorporating a release mechanism to facilitate removal when the yokes are in the upright position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the juvenile vehicle seat is made removable from the seat support, then ease of installation and removal is improved, but safety and secure positioning may be compromised
Solution Approach 1:
The seat support system employs dynamic positioning mechanisms where the lower yoke can be moved between a first position (for installation/removal) and a second position (for secure positioning). The upper yoke is movable relative to the lower yoke, allowing the system to transition between operational states. This dynamic capability enables the seat to be easily installed and removed while maintaining secure positioning during use.
2Reliability
If the juvenile vehicle seat is coupled to both upper and lower yokes in front-facing position, then stability and safety are improved, but device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into distinct upper and lower yokes with separate coupling interfaces. The upper yoke couples to the upper portion of the vehicle seat, while the lower yoke couples to the lower portion. This segmentation allows each yoke to independently perform its coupling function, simplifying the overall design while maintaining stability and safety through distributed attachment points.
3Adaptability or versatility
If the lower yoke is made movable between upright and reclined positions, then adaptability and usability are improved, but mechanism complexity increases
Solution Approach 1:
The lower yoke is designed as a movable component that can transition between a first position (upright) and a second position (reclined). This dynamic positioning capability allows the child restraint system to adapt to different usage scenarios and comfort requirements. The movability is achieved through a mechanism that allows controlled movement while maintaining secure coupling to the vehicle seat throughout the range of motion.
