C-Shaped Pillow Support Structure for Pressure-Free Face-Down Sleeping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients recovering from retinal detachment surgery face discomfort due to traditional C-shaped pillows and sleeping frames that apply pressure to the head, chest, and abdomen, and are not suitable for supine sleeping postures.
Innovation Solution
A C-shaped pillow support with a C-shaped body, partition boards forming compartments for sachets, and an inclined top plate to reduce pressure and enhance comfort, allowing for comfortable procumbent sleeping without pressure on the head, chest, and abdomen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a C-shaped pillow is used for procumbent sleeping, then the patient can maintain the required posture for retinal detachment recovery, but the pillow causes pressure on the head, chest, and abdomen making the patient uncomfortable
Solution Approach 1:
The pillow is divided into multiple independent support regions (first support region for head/face, second support region for chest, third support region for abdomen) that can independently adapt to different body parts, reducing concentrated pressure while maintaining the procumbent posture required for retinal detachment recovery
Solution Approach 2:
Different regions of the pillow have different support characteristics - the first support region has higher support strength for the head and face, while the second and third support regions provide gradual support for the chest and abdomen, creating localized quality variations that optimize both posture maintenance and comfort
2Adaptability or versatility
If traditional C-shaped pillow is used, then procumbent sleeping is enabled, but the patient experiences discomfort during the transition period
Solution Approach 1:
The pillow is segmented into multiple support regions that can independently adapt to the patient's body contours during the transition period, providing customized support for the head, chest, and abdomen simultaneously, thereby improving comfort while maintaining the required procumbent posture for retinal detachment recovery
Solution Approach 2:
The pillow serves multiple functions - it maintains the procumbent posture required for medical recovery, distributes pressure across multiple body regions to prevent discomfort, and provides adaptable support for different patient body types, making it a versatile solution for the transition period

AI summary
A base for supporting a C-shaped pillow is disclosed. The pillow support includes a C-shaped body and a plurality of partition boards. The C-shaped body has an opening, a central hollow, a top plate and a bottom plate. The partition boards are vertically connected between the top plate and the bottom plate to form a plurality of compartments for receiving sachets.
