Open-Space Vehicle Headrest With Mesh See-Through Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed space type headrests obstruct rear passengers' front viewing and limit design flexibility due to their closed shape and narrow internal structure, which also results in a harder physical property.
Innovation Solution
An open space type headrest utilizing a mesh fabric with a see-through characteristic, surrounded by an exterior and mounting cover, and a foam pad, with adjustable tension via a string, creating openings that enhance front viewing and allow for a more comfortable, elastic design while maintaining rigidity and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a closed space type headrest is used, then impact absorption and rigidity are maintained, but front viewing of rear passengers is obstructed
Solution Approach 1:
The patent applies a mesh fabric covering instead of solid fabric, creating a porous structure that allows light transmission and visibility through the headrest. The mesh pattern maintains structural integrity while enabling rear passengers to see through the headrest, thus improving front viewing visibility without compromising impact absorption capabilities.
2Ease of operation
If the internal space is entirely filled with blower and foam pad, then cushioning action is provided, but the physical property becomes hard and design freedom is reduced
Solution Approach 1:
The patent introduces empty spaces within the headrest structure, creating local variations in density and firmness. The foam pad is positioned only in specific areas rather than filling the entire internal space, providing cushioning comfort where needed while maintaining softer overall physical properties and enabling greater design freedom in headrest configuration.
3Strength
If mesh fabric tension is increased, then rigidity is maintained, but comfort feeling is reduced
Solution Approach 1:
The patent utilizes the elastic properties of mesh fabric and adjusts tension parameters to achieve an optimal balance. By controlling the degree of tension in the mesh fabric covering, the headrest maintains sufficient rigidity for safety while preserving the flexibility and comfort needed for seating ease. The elastic nature of the mesh allows dynamic adjustment between rigidity and comfort states.
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 open space type headrest improves rear passengers' forward visibility, provides a comfortable seating experience, and increases design freedom by using a mesh fabric that allows for various shapes and structures while maintaining impact absorption and rigidity.
Implementation Method 1
a covering (40) made of a mesh fabric having a see-through characteristic
Implementation Method 2
the foam pad provides a cushion for supporting the neck of the passenger
Implementation Method 3
capable of promoting a compact design and increasing a degree of design freedom, and particularly, may provide a comfort feeling due to elasticity of a fabric while maintaining rigidity and impact absorption performance by adjusting mesh fabric tension (a static load) in an inside of the headrest through a length of a string

AI summary
An open space type headrest is applied to a vehicle seat in which a covering, which surrounds a foam pad of a volume body positioned on a mounting cover of a flat body coupled to a front surface of an exterior cover formed of a protrusion body, is fixed to the mounting cover, and opening spaces are formed in the exterior cover, the mounting cover, and the foam pad to enlarge front viewing of a rear passenger due to a see-through characteristic of a mesh fabric of the covering.
