Solution Overview

Problem

Extended hospitalization and at-home patient care are challenging due to high costs and the complexity of equipping homes with necessary care systems, with a need for non-disruptive monitoring of patients' vital signs.

Innovation Solution

A bed assembly that elevates the head and foot sections using inflatable air bladders, incorporates contactless sensing, and features a collapsible siderail with integrated point-of-care monitoring, allowing caregivers to access patient information without disturbing the patient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional consumer beds are used for at-home patient care, then the setup is simple and cost-effective, but the bed lacks hospital-grade functionality for monitoring and positioning patients

Engineering Contradiction:
Improvehospital bed functionalityVSAvoidbed assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple hospital bed functions into a single bed assembly including inflatable air bladders for positioning, contactless sensing for vital signs monitoring, and integrated point-of-care monitoring systems, allowing one bed to perform multiple hospital-grade functions simultaneously

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines previously separate hospital bed components (air bladders, sensors, monitoring systems, siderails) into an integrated bed assembly where these elements work together as a unified system, reducing overall complexity while maintaining full functionality

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If hospital-grade monitoring equipment is added to enable vital signs monitoring, then patient care quality improves, but the cost and complexity of equipping the home increases

Engineering Contradiction:
Improvepatient monitoring capabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical contact-based monitoring (physical sensors requiring skin contact) with contactless sensing technology that uses electromagnetic fields or other non-contact methods to detect vital signs, thereby maintaining monitoring reliability while simplifying the system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The bed assembly performs self-monitoring of patient vital signs through integrated sensors and processing systems that automatically collect, analyze, and report health data without requiring external monitoring equipment or manual intervention

Inventive Principle:
Principle #25Self-service

3Loss of information

If caregivers need to access patient information frequently, then monitoring effectiveness improves, but patient disturbance increases

Engineering Contradiction:
Improvevital signs information accessVSAvoidpatient disturbance
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary monitoring system that continuously collects and processes patient vital signs data, presenting information to caregivers in an accessible format without requiring direct interaction with or disturbance of the patient, thus eliminating the need for caregivers to wake or move the patient to obtain information

Inventive Principle:
Principle #24Intermediary (Mediator)
