Contoured Bed Pad with Removable Cover for Patient Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed pads and sheets for repositioning bedridden patients often cause skin injuries due to direct force contact, which can be painful and risky for patients with fragile skin conditions, and do not provide adequate support for lower extremities during movement.
Innovation Solution
A bed pad system with a rectangular base pad featuring a uniquely contoured central opening for superior support of lower extremities and a removable, waterproof, liquid-absorbent cover pad secured with Velcro for easy access and movement, minimizing direct contact and reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bed pad system provides superior support for lower extremities during patient repositioning, then patient support and comfort are improved, but device complexity increases due to the contoured opening design
Solution Approach 1:
The bed pad system is divided into two separate components: a base pad with a contoured opening for lower extremity support and a removable cover pad that provides the patient support surface. This segmentation allows each component to be optimized independently - the base pad provides structural support while the cover pad provides patient comfort and hygiene functionality.
Solution Approach 2:
The removable cover pad is designed to fit over the contoured opening of the base pad, creating a nested structure where the cover pad sits within the opening. This nesting approach allows the cover pad to be easily removed and replaced while maintaining the structural integrity of the base pad.
2Ease of operation
If a removable cover pad is added for easy access and hygiene, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cover pad is designed with dynamic characteristics - it can be easily inserted and removed from the base pad. The elastic or flexible nature of the cover pad allows it to be dynamically adjusted and replaced by caregivers without requiring complex tools or procedures, maintaining simplicity despite the added functionality.
3Reliability
If the base pad has a contoured opening for lower extremity support, then patient comfort is improved, but manufacturing precision requirements increase
Solution Approach 1:
By separating the contoured opening structure from the patient support surface (cover pad), the manufacturing complexity is distributed. The base pad can be manufactured with the contoured opening using standard molding techniques, while the cover pad can be manufactured separately with focus on comfort properties rather than precise geometric contours.

AI summary
A bed turning composite dual pad system to facilitate the care of a patient used in changing their position on a bed while providing clear access to their backside as required. A base pad is positioned under a patient with a centrally aligned longitudinally offset contoured opening within allowing the caregiver to easily turn and roll a patient with the base pad for ease of care access position. An adaptable absorbent cover pad is removably affixed over the contoured opening on the underside of the base pad for liquid containment management if needed.
