Infant Carrier Headrest Buffer Structure for Emergency Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant carriers face safety issues during emergency brakes due to headrest deformation causing impact on infants, as the headrest and seat easily squeeze together due to inertia, leading to potential harm.
Innovation Solution
A headrest support structure with a buffer mechanism, including a reinforcement tube attached to the headrest and an elastic pad on the seat, which provides a buffer to prevent direct contact and deformation, combined with an adjustable height mechanism for comfort and safety across different ages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the headrest and seat are directly connected without buffer mechanism, then the structure is simple, but the headrest deforms during emergency brake causing impact on infant
Solution Approach 1:
The patent introduces a buffer mechanism comprising a buffer seat, buffer block, and elastic component positioned between the headrest and seat. This beforehand cushioning structure absorbs impact forces during emergency braking before they reach the infant, preventing headrest deformation and ensuring safety without requiring complex active control systems.
2Reliability
If the headrest is made rigid to prevent deformation, then safety is improved, but the headrest cannot provide comfortable support for infants at different ages
Solution Approach 1:
The patent implements a dynamic headrest system with height adjustment capability through a locking mechanism that allows the headrest to be positioned at multiple heights along guide rods. This enables adaptation to infants of different ages and sizes while maintaining safety through the buffer mechanism that prevents deformation during impact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents headrest deformation and minimizes impact on infants by providing a buffer mechanism, ensuring safety and comfort during sudden movements, and allowing adjustable height support for various age groups.
Implementation Method 1
a pad, and the pad is an elastic structure disposed on the seat and disposed opposite to the reinforcement tube, and the pad is squeezed elastically by the reinforcement tube to provide a buffer to the headrest

AI summary
A headrest support structure is applied to a safety seat. The headrest support structure includes a buffer mechanism. The buffer mechanism is connected to a headrest and a seat of the safety seat. Elastic deformation of the buffer mechanism provides a buffer to the headrest and the seat. The headrest support mechanism has a high safety factor and provides a buffer to the headrest and the seat during an emergency brake for accident prevention. The present application further provides an infant carrier having the headrest support structure.
