Concave Side Pillow Layout for Post-Surgery Back Sleeping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After a mastectomy or other surgeries, patients often find it uncomfortable to sleep on their side or stomach, necessitating a supportive system for sleeping on their back to alleviate pain and discomfort.
Innovation Solution
A pillow system comprising two symmetrical, elongate side pillows with concave regions and optional additional pillows for head and body support, designed to cradle and support the user's body when laying on their back, providing customizable comfort and pressure relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a patient uses a traditional pillow after mastectomy surgery, then the patient can sleep on their back, but the patient experiences discomfort and pain due to lack of body support
Solution Approach 1:
The pillow system is divided into multiple discrete components: two elongate side pillows with concave regions, a head pillow, and optional support pillows. Each component serves a specific function - the side pillows support the torso and hips, the head pillow supports the head, and support pillows provide additional positioning. This segmentation allows the system to address multiple support needs simultaneously while maintaining overall simplicity.
Solution Approach 2:
The pillow system employs a nested arrangement where smaller pillows (head pillow, support pillows) are positioned within or between the larger elongate side pillows. The support pillows can be placed in the void areas created by the concave regions of the side pillows, creating a layered, nested structure that maximizes space utilization and provides graduated support from the largest to smallest components.
2Ease of operation
If a patient sleeps on their side or stomach after surgery, then the patient may find it more comfortable, but this position is not recommended for healing
Solution Approach 1:
The elongate side pillows feature concave regions at specific locations along their length. These concave regions create localized void areas that are strategically positioned to accommodate different body parts (shoulders, hips, knees). This local modification of the pillow structure provides targeted support and pressure relief at critical areas while maintaining the recommended supine sleeping position for healing.
Solution Approach 2:
The concave regions in the side pillows create curved, hollow spaces that conform to the natural contours of the human body. These curved void areas allow the pillows to cradle and support rounded body parts like shoulders and hips, distributing pressure evenly and preventing discomfort that would otherwise motivate patients to adopt non-healing sleep positions.
3Reliability
If a patient uses a simple pillow after surgery, then the device is easy to use, but it does not provide adequate pressure relief and body alignment
Solution Approach 1:
The elongate side pillows serve multiple functions simultaneously: they support the torso, hips, and legs; create void areas for additional support pillows; and provide overall body alignment. The head pillow and support pillows add specialized functions for head positioning and gap filling. This multi-functionality allows the system to achieve comprehensive pressure relief and alignment without requiring an excessive number of separate components.
Solution Approach 2:
The pillow system transitions from traditional two-dimensional flat pillows to three-dimensional elongate pillows with concave regions and void areas. This dimensional enhancement creates internal hollow spaces and varied surfaces that can accommodate the complex contours of the human body, providing pressure relief and alignment in multiple directions and planes simultaneously.

AI summary
A pillow system for use by a user laying on their back, such as for use after a mastectomy or other surgery. The pillow system provides a cushioning and supportive system. In one particular implementation, the pillow system has two elongate side pillows for placing under and extending from at least a user's shoulders to the user's knees. The two side pillows have an inner edge that includes two concave regions, thus when the two pillows are placed next to or alongside each other, two generally void areas are formed. The pillow system may include a head pillow and/or a support pillow(s), such as a wedge-shaped pillow.
