Hooded Pillowcase Structure for Stable Head Support While Sitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pillows and neck pillows fail to prevent head tilting or falling forward while sleeping in a sitting position, leading to neck strain and pain due to their design, which does not provide adequate support or stabilization.
Innovation Solution
A pillow assembly with a hood structure sewn onto the pillowcase along a single main seam, featuring forward and rear seams, pleats, and a drawstring hem to securely restrain the head, preventing unintentional movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional pillow is used by a person sleeping in a sitting position, then the pillow provides head support, but it increases the likelihood that the head will tilt to the side or fall forward
Solution Approach 1:
The pillow is divided into multiple functional segments: a traditional pillow portion for head support and a separate hood structure with restraining elements. This segmentation allows each part to perform its specific function - the pillow provides support while the hood prevents unwanted head movement through straps and positioning features
Solution Approach 2:
The hood structure acts as an intermediary between the head and the pillow. It transfers and distributes the support forces more evenly across the head and neck area, preventing concentration of force that would cause tilting. The hood's straps and positioning elements mediate the interaction between the sleeping person and the pillow to maintain proper head alignment
2Reliability
If a traditional neck pillow is used to support the neck in a sitting position, then the back and sides of the neck are supported, but the head can still fall forward and neck injury may occur
Solution Approach 1:
The hood structure serves multiple functions simultaneously: it covers the head like a traditional hood, provides restraint through straps to prevent forward falling, and works with the pillow to maintain proper positioning. This multi-functionality addresses both the support need and the injury prevention need in a single integrated system
Solution Approach 2:
The hood and strap system applies preliminary restraining force before the head can fall forward. By having the hood in place with adjustable straps, the system prevents the harmful action (head falling forward) before it occurs, rather than reacting after the injury mechanism is activated
3Ease of operation
If hoods are connected to pillows in prior art systems, then the hood covers the eyes and ears for better sleep in loud or bright environments, but the hood does not stabilize the user's head or prevent neck injuries
Solution Approach 1:
The hood is designed to perform multiple functions: it covers the eyes and ears for comfort in various environments, while simultaneously providing head stabilization through its structural design and integration with restraining straps. This eliminates the need for separate eye/ear coverage and head stabilization devices

AI summary
A pillow assembly that utilizes a hood to inhibit certain movements of the head. The pillow assembly utilizes a pillowcase having a top surface and a bottom surface. The pillowcase can be stuffed to become a pillow or can be used to cover a preexisting pillow. A hood structure is sewn onto the pillowcase. The hood structure is sewn onto the pillowcase along a single main seam. The sewing of the hood to the pillowcase along a single seam creates features in the hood structure that are beneficial to the comfortable restraint of the user's head. Furthermore, the hood structure has a forward opening, a hood apex, and a rear seam that extends from the apex down to the single main seam. The rear seam also helps to reinforce the hood structure so it can better prevent unintentional movements of the user's head.
