Foldable Headrest with Chin Support for Upright Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in upright seating positions on long-distance travel face difficulties in relaxing and sleeping due to lack of horizontal recline in most seats, leading to head tilting sideways and forward, which existing headrests fail to prevent effectively, and existing solutions are bulky and non-portable.
Innovation Solution
A portable, adjustable, and foldable headrest with a chin support that clamps to the seat back, featuring a telescoping design, adjustable height, and rotatable chin rest for customizable comfort, allowing for secure head support and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional foam ergonomic pillow is used, then head support comfort is improved, but device portability deteriorates due to bulky size
Solution Approach 1:
The headrest is divided into multiple functional segments: a clamp mechanism for attachment, a vertical support member, and a chin support member. These segments can be adjusted independently and folded together for compact storage, resolving the contradiction between providing comprehensive head support and maintaining portability.
Solution Approach 2:
The chin support member is designed to be rotatable and adjustable relative to the vertical support member, allowing dynamic adaptation to different user preferences and head positions. This dynamic adjustability provides customized comfort while the entire structure can be folded into a compact form for portability.
2Ease of operation
If existing headrest supports with curved bars are used, then basic head resting is improved, but effectiveness in preventing forward head tilting deteriorates
Solution Approach 1:
Instead of supporting only the back of the head with curved bars, this invention inverts the approach by adding a chin support member that supports the front of the head/chin area. This inverted support configuration effectively prevents forward head tilting while maintaining basic head resting capability.
3Ease of manufacture
If a fixed-size headrest is designed, then manufacturing simplicity is improved, but adaptability to different seat back sizes deteriorates
Solution Approach 1:
The clamp mechanism incorporates adjustable components that allow the headrest to adapt to different seat back sizes and shapes. The vertical support member and chin support member can be adjusted in position and orientation, enabling the same headrest design to fit various seat configurations while maintaining manufacturing simplicity through modular components.
4Stability of the object's composition
If a non-foldable headrest structure is used, then structural stability is improved, but portability for ease of transport deteriorates
Solution Approach 1:
The headrest is segmented into collapsible components connected by joints and fasteners. The chin support member can be folded against the vertical support member, and the entire assembly can be disassembled or collapsed into a compact form for transport, while maintaining structural stability when deployed through the clamp mechanism and support members.

AI summary
Apparatus, devices, systems, and methods for clamping a length adjustable hook on a portable headrest with chin support to a top or side of a seat back, 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. The headrest can have telescoping vertical members which are length adjustable for different sized users. The chin support can have a cushion that is rotatable at different increments for comfort. The cushion can be slotted to allow the vertical member to be placed inside the slotted portion.
