Solution Overview

Problem

Existing child vehicle seats and booster seats lack head and neck support, leading to discomfort and potential injuries from head rolling during sleep, especially in infants and children whose neck muscles are not strong enough to maintain a stable head position during vehicle movements.

Innovation Solution

A sleeping aid comprising a pad or pillow with a thicker first portion and a thinner second portion, offset and enclosed by the first, providing support for the child's head, connected to the seat via a strap or elastic band with a pivot connection for adjustable comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a child sleeps in an upright seated position in a vehicle seat, then the child can rest during travel, but the head will fall forward or roll to the left or right due to weak neck muscles, causing strain and discomfort

Engineering Contradiction:
Improvesleep durationVSAvoidhead strain and neck injury
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

A sleeping aid device acts as an intermediary between the child's head and the vehicle seat, providing the necessary support that the child's weak neck muscles cannot provide. The device includes a support surface with a head support region and a neck support region that together stabilize the head and prevent harmful movements during sleep.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sleeping aid device has different regions with different support characteristics - a head support region and a neck support region. Each region is designed with specific local properties to address the particular needs of different parts of the head and neck, providing customized support where needed most.

Inventive Principle:
Principle #3Local quality

2Reliability

If standard vehicle seat belts are used to secure the child seat, then the upper body is supported according to safety standards, but the head and neck regions remain unsupported, potentially resulting in severe head and neck injuries

Engineering Contradiction:
Improvesafety complianceVSAvoidhead and neck injury risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The sleeping aid device segments the support function into distinct regions - head support and neck support - that are separate from the standard seat belt system. This segmentation allows the device to provide targeted support to the head and neck areas without interfering with the upper body restraint function of the seat belt.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sleeping aid device serves as an additional intermediary support system that works in conjunction with the seat belt. While the seat belt provides upper body restraint, the sleeping aid specifically addresses the head and neck support gap, creating a multi-layered protection system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If existing head support devices are used, then some head support is provided, but they are bulky in size and weight, require intricate installation, and cannot be readily adjusted to accommodate various head sizes

Engineering Contradiction:
Improvehead supportVSAvoidinstallation and adjustment complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The sleeping aid device incorporates adjustable parameters such as the position and orientation of the support surface to accommodate various head sizes and shapes. This adjustability allows the device to be customized for different children without requiring multiple different devices or complex installation procedures.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The sleeping aid device is designed to be universally applicable to different children and seat types. The support surface can be positioned and oriented to accommodate various head sizes, making a single device suitable for multiple users and situations, thereby reducing the need for multiple specialized devices.

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

4Object-affected harmful factors

If existing head support devices are used, then some head support is provided, but they are bulky in both size and weight

Engineering Contradiction:
Improvehead supportVSAvoidsleeping aid weight
Core Design Contradiction:
Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The sleeping aid device extracts only the essential head and neck support function from the complex, bulky existing devices. By focusing on the core support needs and eliminating unnecessary bulk and weight, the device provides effective head support in a lightweight, compact form that is easy to handle and install.

Inventive Principle:
Principle #2Taking out (Extraction)
