Buffered Headrest Support Structure for Infant Brake Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infant safety seats and strollers face issues where the headrest and seat can deform during emergency brakes, causing the headrest to squeeze the infant 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 across different infant 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 infant injury
Solution Approach 1:
The patent applies beforehand cushioning by introducing a buffer mechanism comprising a buffer member and elastic member between the headrest and seat before any impact occurs. The buffer member is positioned to absorb impact forces during emergency braking, while the elastic member provides pre-tensioned support. This preemptive cushioning structure prevents headrest deformation and potential infant injury without requiring complex active control systems.
Solution Approach 2:
The patent employs an intermediary approach by inserting a buffer mechanism as a mediator between the headrest and seat. The buffer member acts as the intermediary element that absorbs and dissipates impact forces, preventing direct transmission of deformation forces from the seat to the headrest. This intermediary structure resolves the contradiction by adding a protective layer that enhances safety without requiring complete redesign of the entire support system.
2Adaptability or versatility
If the headrest uses fixed height design, then the structure is simple, but it cannot provide comfortable support for infants of different ages
Solution Approach 1:
The patent applies dynamics by transforming the fixed headrest into an adjustable system that can adapt to different infant ages and sizes. The headrest incorporates height adjustment mechanisms allowing it to move between multiple predetermined positions, and tilt adjustment mechanisms allowing angular adjustment. This dynamic capability enables the headrest to provide optimal support for infants at various developmental stages while maintaining structural integrity through the buffer mechanism.
Solution Approach 2:
The patent employs parameter changes by allowing the headrest to modify its physical parameters including height position and tilt angle. The adjustment mechanisms enable changing the headrest's spatial parameters to match different infant requirements. The buffer mechanism's elastic properties also provide dynamic parameter adjustment during impact events, automatically optimizing the support characteristics based on the force applied.
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 buffer mechanism effectively absorbs impact and prevents deformation, enhancing safety by minimizing the risk of injury to the infant during sudden movements, while the adjustable height ensures comfortable support for infants of varying ages.
Implementation Method 1
An elastic member is disposed on the headrest and is in contact with the locking member. Elastic deformation of the buffer mechanism provides a buffer to the headrest and the seat.
