Neck supporting device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headrests cannot adjust their position to accommodate different occupants and may cause neck injuries during accidents or sudden braking due to lack of support for the neck part.
Innovation Solution
A neck supporting device with a housing, main body, and strap system that can be attached to a vehicle seat, featuring support portions and a withdrawal device with a ratchet and stopper mechanism to adjust neck support based on occupant needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a headrest is integrated with the seat and protrudes at ordinary times, then the headrest can support the head, but the position cannot be changed and the neck may be injured in accidents
Solution Approach 1:
The headrest is designed with a movable main body that can be withdrawn from the housing to change its position. The withdrawal device allows the main body to move between retracted and extended positions, enabling the headrest to adapt to different situations - providing neck support during accidents when retracted and head support during normal use when extended.
Solution Approach 2:
The headrest is divided into separate components: a housing that remains fixed on the seat, and a main body that can be withdrawn. This segmentation allows the headrest to change its effective position and configuration, providing both stable attachment and position adjustability.
2Ease of operation
If the headrest slides upward or downward to adjust height, then the head can be fitted, but the neck part cannot be supported
Solution Approach 1:
The main body includes support portions with specific local structures designed to support the neck. When the main body is withdrawn, these support portions positionally align with the occupant's neck, providing localized neck support in addition to the overall head support function.
3Adaptability or versatility
If a withdrawal device with ratchet and stopper is added, then the main body can be withdrawn for neck support, but the device complexity increases
Solution Approach 1:
The withdrawal device uses a ratchet mechanism that allows the main body to be withdrawn easily in one direction while automatically preventing backward movement. The stopper component works with the ratchet to provide automatic locking, eliminating the need for complex control systems or multiple actuators.
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
Provides stable neck support, prevents injuries by maintaining cervical vertebrae alignment, and enhances seat comfort through adjustable neck support.
Implementation Method 1
the stopper may be connected to the connection member by an elastic member. In addition, the elastic member may be a spring.
