Solution Overview

Problem

Existing child restraint systems struggle to support different types of child seats in various orientations and angles of recline, making it difficult for caregivers to securely install and remove children, especially in rearward-facing configurations.

Innovation Solution

A support base with a positioning assembly that allows for adjustable positioning and orientation of the child seat, including rotational and translational movements, enabling the seat to be easily adjusted between forward- and rearward-facing orientations and positioned closer to the caregiver for improved accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base portion is adjusted to a proper reclined angle and secured to the vehicle, then the child restraint system is securely installed, but the seat cannot be easily accessed by the caregiver for loading and unloading children

Engineering Contradiction:
Improvesecure installationVSAvoidaccessibility for loading/unloading
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The positioning assembly incorporates movable components including a sliding mechanism with first and second positioning elements that can translate along guide rails, and a rotating mechanism with a third positioning element that pivots about a pivot axis. These dynamic elements allow the seat to move between a stowed position (close to the base) and a deployed position (extended toward the caregiver), providing both secure installation and easy accessibility.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If existing base portions are designed for fixed orientations, then the structure is simple, but they cannot support different types of seats in different orientations and at various angles of recline

Engineering Contradiction:
Improvestructural simplicityVSAvoidmulti-orientation support
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The positioning assembly is designed to support multiple seat types and orientations through its multi-degree-of-freedom mechanism. The sliding mechanism allows adjustment along the longitudinal axis, the rotating mechanism enables angular adjustment, and the recline mechanism provides inclination adjustment. This universal design accommodates forward-facing, rearward-facing, and side-facing orientations, as well as various recline angles, all within a single base structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the child seat is fixed in position on the base, then the installation is straightforward, but the caregiver must bend and reach significantly to access the child

Engineering Contradiction:
Improveinstallation simplicityVSAvoidcaregiver accessibility
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The positioning assembly automatically positions the seat in an optimal location for caregiver interaction. When the seat is deployed, the mechanism translates and rotates the seat forward and upward, bringing it closer to the caregiver's natural standing position. This preliminary positioning action reduces the need for excessive bending and reaching, making the loading and unloading process more ergonomic while maintaining simple installation procedures.

Inventive Principle:
Principle #10Preliminary action

AI summary

Child restraint systems are provided position positioning systems and assemblies to provide relative movement between a support base and a child seat such that the child seat is rotatable and translatable relative to the support base.
