Adjustable Vehicle Head Rest with Neck Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head rests in vehicles provide limited comfort and support, especially for occupants who lean forward, and offer negligible neck support, increasing the risk of whiplash injuries during collisions.
Innovation Solution
A head rest assembly with a head support portion and a neck support portion, connected by adjustable connection members that can be customized to fit various vehicle seats, featuring a concave recess for head support and a forward-extending neck support to enhance comfort and reduce injury risk during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional head rests are used, then the structure is simple and easy to manufacture, but the comfort and neck support for occupants who lean forward is insufficient
Solution Approach 1:
The head rest assembly is divided into separate functional components: a head support portion and a neck support portion connected by adjustable connection members. This segmentation allows each part to be optimized independently while providing adaptability through the adjustable connection mechanism between segments.
2Reliability
If conventional head rests are used, then the device is simple, but the support for the occupant's neck during collisions is negligible
Solution Approach 1:
The neck support portion is positioned in advance to provide preliminary support to the occupant's neck before a collision occurs. The adjustable connection members pre-position the support structure to ensure proper alignment and support readiness, reducing the risk of whiplash injuries during unexpected collisions.
3Adaptability or versatility
If the head rest is fixed in position, then the structure is stable, but it cannot accommodate occupants who lean forward
Solution Approach 1:
The connection members are designed to be adjustable, allowing the head rest assembly to dynamically adapt its position and configuration to accommodate occupants who lean forward. This dynamic adjustability maintains structural stability while providing versatility for different seating positions.
