Foldable Chin-Support Headrest for Upright Seat Sleep
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in upright seating positions on long-distance travel face difficulties in relaxing and sleeping due to the lack of horizontal recline in most seats, leading to head instability and discomfort, with existing headrest solutions being bulky, non-adjustable, and non-foldable.
Innovation Solution
A portable, adjustable, and foldable headrest with a chin support that clamps onto a seat back, featuring a telescoping design, adjustable height, and a rotating chin rest with a cushion, allowing for customizable support and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional foam pillow is used for head support, then head comfort is improved, but the device becomes bulky and difficult to store
Solution Approach 1:
The headrest is divided into multiple segments including a clamp portion, vertical member, and chin rest that can be assembled and disassembled. This segmentation allows the device to provide comprehensive head support functionality while enabling compact storage when not in use
Solution Approach 2:
The chin rest folds against the vertical member, and the entire assembly can be compacted into a small package. The nested structure allows the device to maintain full functionality when deployed while occupying minimal space during storage
2Adaptability or versatility
If a single pad headrest is used, then head support is provided, but the device cannot prevent forward bending and lacks adjustability
Solution Approach 1:
Different parts of the headrest have specialized functions: the clamp portion provides secure attachment to the seat back, the vertical member provides head leaning support, and the chin rest provides forward bending prevention. This local specialization allows comprehensive head support coverage without requiring excessive structural complexity
Solution Approach 2:
The headrest device performs multiple functions including head leaning support, forward bending prevention, and adaptability to different seat backs through the adjustable clamp. This multi-functionality achieves comprehensive head support coverage while maintaining relatively simple device structure
3Stability of the object's composition
If a non-foldable headrest is used, then head support stability is maintained, but portability and ease of transport are reduced
Solution Approach 1:
The chin rest is designed to be foldable against the vertical member, transforming the device from a static bulky structure to a dynamic compact assembly during storage. When deployed, the chin rest provides stable head support, and when folded, it enables easy portability without compromising the stability function
4Adaptability or versatility
If a fixed size headrest is used, then manufacturing is simplified, but adaptability to different seat backs and passenger sizes is reduced
Solution Approach 1:
The clamp portion is designed with adjustability to accommodate different seat back sizes and shapes. This dynamic adjustment capability allows a single device design to fit various seats without requiring multiple size variants, maintaining ease of manufacture while achieving broad seat compatibility

AI summary
Apparatus, devices, systems, and methods for clamping a portable headrest with chin support on top a back of a seat, which is both adjustable and foldable to be portable for ease in transport. The horizontal chin rest pivotally attached to the bottom of a vertical member allows a sitting person's head to be supported in an upright position, while restricting movement both forward and side to side.
