Contoured Travel Pillow for Cervical Alignment in Seated Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional travel pillows lack adequate lateral support, vertical support, and cushioning, often causing neck discomfort and misalignment during long trips, especially in seated or semi-reclined positions.
Innovation Solution
A travel pillow design featuring a headrest, neck support, and lateral side buttresses that provide anatomically correct alignment, with a contoured bottom to ensure the pillow stays in place and offers cushioning through the use of foam or inflatable materials, allowing for deflection and secure cradling of the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional travel pillows (rectangular, inflatable, or horseshoe shaped) are used, then the device complexity is simple, but the lateral support, vertical support, and head cushioning are insufficient
Solution Approach 1:
The pillow is divided into distinct functional segments: a horseshoe-shaped neck support portion with lateral side buttresses for neck stabilization, and a separate contoured headrest portion for head cushioning and lateral support. This segmentation allows each part to specialize in its specific support function without compromising overall simplicity.
Solution Approach 2:
The invention transitions from conventional 2D flat or simple 3D pillow shapes to a multi-dimensional contoured structure with lateral side buttresses extending outward and a specifically shaped headrest with curvature matching the human head轮廓. This dimensional enhancement provides comprehensive lateral and vertical support while maintaining reasonable structural complexity.
2Ease of manufacture
If the pillow structure is simplified for ease of manufacture, then the ease of manufacture improves, but the ability to maintain cervical spine alignment and provide anatomical support deteriorates
Solution Approach 1:
The pillow is pre-formed during manufacturing with the correct anatomical contours, lateral side buttress positions, and headrest curvature. This preliminary shaping ensures that when the user places their head and neck on the pillow, the anatomical alignment is automatically achieved without requiring complex adjustable mechanisms or post-manufacturing customization.
Solution Approach 2:
The invention uses specific geometric parameters - the horseshoe shape width, lateral side buttress height and angle, headrest curvature radius, and contoured bottom profile - that are optimized during manufacturing to provide anatomical support. These fixed parameters ensure consistent cervical spine alignment across all pillows of this design.
3Stability of the object's composition
If the pillow uses fixed rigid structure for stability, then the stability improves, but the cushioning effect and adaptability to head movements deteriorates
Solution Approach 1:
The pillow employs dynamic materials (memory foam or inflatable chambers) that automatically adjust their firmness and shape in response to applied pressure from the user's head and neck. This allows the pillow to maintain stable support for cervical alignment while adapting to different head positions and movements during sleep.
Solution Approach 2:
The use of flexible memory foam or inflatable material creates a shell-like structure that can deform and conform to the user's anatomy while maintaining overall structural integrity. This flexibility enables the pillow to cradle the head securely and provide lateral support through the movable lateral side buttresses.
4Reliability
If the pillow provides comprehensive lateral and vertical support with contoured design, then the neck support effectiveness improves, but the device complexity increases
Solution Approach 1:
The invention merges multiple support functions into a single integrated pillow structure: the horseshoe-shaped neck support portion combines lateral side buttresses for neck stabilization with the contoured headrest for head cushioning, all supported by a contoured bottom profile. This integration provides comprehensive lateral and vertical support without requiring multiple separate devices.
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 pillow maintains cervical spine alignment, prevents neck soreness, and ensures comfort by providing ample lateral and vertical support, keeping the head secure and cushioned during extended travel periods.
Implementation Method 1
the weight of the head and resulting force causes the headrest and neck support to deflect or bend downward, this deflection creates improved cushioning effect
Implementation Method 2
One embodiment of the present invention the travel pillow is comprised of one of open cell foam or closed cell foam having the density required to give proper support and proper deflection
