Rotatable Child Safety Seat With Dual Tether Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable child car seats are heavy and unwieldy due to large seat bases required for safety, and their single-point attachment for seat belts or LATCH systems limit harness weight ratings, restricting safe use to smaller infants and toddlers.
Innovation Solution
A rotatable child car seat design featuring a seat shell coupled to a rotating pedestal within a seat base, with dual attachment areas for seat belts and LATCH tethers, allowing 90-degree rotation and adjustable recline positions, enabling safe use for a wider range of children by distributing the attachment points and reducing the seat base size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seat base is made large to provide sufficient protection in both forward-facing and rearward-facing configurations, then safety is improved, but the car seat becomes heavy and unwieldy
Solution Approach 1:
The car seat is divided into two main components: a stationary seat base that remains attached to the vehicle seat, and a rotatable seat shell that can be rotated independently. The seat base contains the attachment points for seat belts and LATCH systems, while the seat shell houses the child. This segmentation allows the seat base to be optimized for safety without requiring excessive size, as the rotatable mechanism enables reconfiguration without moving the entire assembly.
Solution Approach 2:
The patent introduces a rotatable mechanism that allows the seat shell to rotate between forward-facing and rearward-facing configurations. This dynamic element enables the seat to adapt its orientation based on the child's age and safety requirements, eliminating the need for a excessively large stationary base that would be required to accommodate all configurations simultaneously.
2Adaptability or versatility
If attachment points for seat belts and LATCH tethers are positioned at the seat base, then rotational capability is maintained, but harness weight rating is reduced limiting use to smaller children
Solution Approach 1:
The patent positions attachment points in multiple locations: some at the seat base and others at the seat shell. By utilizing vertical and spatial distribution of attachment points across different dimensions, the system achieves both rotational capability (through base attachment points) and higher weight ratings (through additional shell attachment points that provide better leverage and distribution for heavier children).

AI summary
A rotatable child safety seat can include a seat shell for receiving a child therein, a rotating pedestal, and a seat base. The pedestal and seat shell can rotate with respect to the seat base. The pedestal can include a locking pin and the seat base can include a multitude of pin receiving apertures that allow a user to rotate the seat shell and pedestal in either a clockwise or counter-clockwise direction at a number of different angles or positions. The child safety seat can also include two separate seat belt/LATCH tether pathways. One seat belt/LATCH tether pathway can be provided on the seat back of the seat shell and can be used when the child safety seat is in a forward-facing configuration and the other seat belt/LATCH tether pathway can be provided in the seat base and used when in a rearward-facing configuration.
