Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Child safety seats, particularly those for newborns and infants, are inadequately protected during side impacts due to the lack of individualized adaptation of damping elements to the child's shoulder and head position, leading to potential injury from unmanaged impact energy.

Innovation Solution

A newborn insert for child safety seats featuring an energy-transferring element made of inherently stable material, positioned at the child's shoulder height, which transfers impact energy to the body, thereby protecting the head from side impacts by displacing the shoulder and distributing the energy across the body's mass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If soft, planar damping materials are used in child safety seats, then the child's head is cushioned during normal use, but during side impact the impact energy is not effectively transferred to the body, leaving the head vulnerable

Engineering Contradiction:

Improvehead protection during side impactVSAvoidimpact energy transfer reliability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent introduces energy-transferring elements with specific mechanical properties positioned at the child's shoulder region, creating localized zones with different functional characteristics. The head region maintains soft damping materials for comfort, while the shoulder region incorporates rigid energy-transferring elements that actively channel impact energy to the body during side collisions

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The energy-transferring elements serve as intermediary structures between the external impact force and the child's body. These elements are positioned to receive lateral impact forces and transfer them through the shoulder region to the child's torso, acting as a mechanical mediator that redirects harmful energy away from the head

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If damping elements are designed for general use, then the child safety seat accommodates various children, but the elements cannot be individually adapted to each child's shoulder and head position

Engineering Contradiction:

Improveadaptation to child's shoulder and head positionVSAvoidindividualized damping element configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The damping system is segmented into functionally distinct zones: soft damping materials for the head region providing passive cushioning, and separate rigid energy-transferring elements for the shoulder region providing active impact management. This segmentation allows each zone to be optimized independently for its specific protective function

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs materials and structures with different mechanical responses to loading conditions. The soft damping materials deform under normal use to provide comfort, while the rigid energy-transferring elements maintain structural integrity during side impacts to channel forces effectively, creating a dynamically responsive system

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the child safety seat is installed on side seats with small lateral distance to the vehicle interior, then the seat is easily installed, but during side impact the seat hits the vehicle interior with substantial speed causing strong deceleration

Engineering Contradiction:

Improveinstallation convenienceVSAvoiddeceleration force on child during side impact

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The patent converts the harmful lateral impact force into a beneficial protective mechanism by using the energy-transferring elements to channel the impact energy through the child's shoulder region to the body. The system accepts the inevitability of side impact forces and transforms them into controlled energy transfer that protects the head while utilizing the child's own body mass as a protective element

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A newborn insert for a child safety seat may include an accommodation region for a child, and an energy-transferring element. The energy-transferring element may include an inherently stable component, and may be arranged laterally at the accommodation region such that the energy-transferring element is positioned at the child's shoulder height when the child is placed in the accommodation region.
