Solution Overview

Problem

Current patient care systems in healthcare settings face challenges in efficiently conveying information and electrical energy between patient-centric devices and bed systems without the need for third-party intervention, which can delay critical responses such as CPR or compromise patient safety by requiring manual configuration of bed states.

Innovation Solution

A noncontact electromagnetic coupling system between a patient-wearable item and a hospital bed, utilizing electromagnetic couplers to transfer information and electrical energy, allowing the bed to automatically configure based on patient-specific data from wearable devices, such as sensors and identification tags, to ensure safe and responsive care.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If third-party intervention is used to convey information and energy between patient devices and bed systems, then system compatibility and control can be maintained, but response time delays and potential safety compromises occur

Engineering Contradiction:
Improvepatient safetyVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the intermediary communication layer by enabling direct electromagnetic coupling between patient-centric devices and the occupant support system. This eliminates the third-party intervention that caused delays while maintaining system reliability through direct, dedicated energy and data transfer paths.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces electromagnetic fields as a new intermediary medium that enables direct communication between patient devices and bed systems without traditional wired or wireless third-party intermediaries. This electromagnetic mediator allows simultaneous power transfer and data communication, resolving the time delay issue while maintaining system control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If manual configuration of bed states is required, then system control and monitoring can be maintained, but caregiver efficiency and patient safety are compromised

Engineering Contradiction:
Improvebed configurationVSAvoidcaregiver efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent enables the bed system to automatically configure itself based on information received directly from patient-centric devices. The system self-adjusts bed states, mattress firmness, and positioning without requiring manual caregiver intervention, thereby improving both ease of operation and caregiver productivity simultaneously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary configuration actions by receiving patient information in advance and automatically preparing the appropriate bed state before patient arrival or before treatment is needed. This eliminates the need for manual configuration at the moment of care delivery, improving caregiver efficiency.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If direct communication between patient devices and bed systems is established, then response time and efficiency are improved, but system complexity and energy requirements increase

Engineering Contradiction:
Improvecare response efficiencyVSAvoidelectromagnetic coupling system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional electromagnetic coupling system that simultaneously handles power transfer, data communication, and device identification. This universal interface consolidates multiple functions into a single system, reducing overall complexity despite the advanced capabilities provided.

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

Solution Approach 2:

The patent merges power transfer and data communication functions into a single electromagnetic coupling interface. By combining these functions that were previously separate, the system reduces the number of components and interfaces needed, thereby managing complexity while delivering direct communication benefits.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A patient care system described herein includes a first electromagnetic coupler associated with the patient, at least one patient-centric appliance in communication with the first coupler, and an occupant support for supporting the patient. The occupant support has a second electromagnetic coupler associated therewith. At least one of the couplers is connectable to an electrical energy source for energizing the coupler. The first and second couplers form a noncontact electromagnetic coupling. An occupant wearable item and an occupant support, both of which are useable with the patient care system, are also described.
