Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to reduce the labor required for caregivers to deliver quality patient care, lower healthcare costs, and enhance patient comfort in in-patient environments, while also improving caregiver efficiency.
Innovation Solution
A patient support apparatus equipped with a controller, sensors, and a notification system that provides visual indications of component statuses through iconic representations, integrated features like a patient pendant, storage spaces, and monitoring systems for patient comfort and safety, and connectivity with electronic medical records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual monitoring methods are used by caregivers, then direct patient care can be provided, but caregiver workload and labor costs increase
Solution Approach 1:
The patient support apparatus performs self-monitoring of its own components (mattress inflation, motor status, etc.) through integrated sensors and automatically communicates status information through the notification system, eliminating the need for continuous manual monitoring by caregivers
Solution Approach 2:
The patent replaces manual mechanical monitoring with an automated electronic monitoring system that uses sensors, controllers, and visual notification displays to track device status and patient conditions, substituting human labor with automated technological systems
2Reliability
If comprehensive monitoring systems are implemented, then patient care quality improves, but device complexity increases
Solution Approach 1:
The monitoring system is divided into separate functional modules: sensors for detecting status, a controller for processing information, and a notification system for visual output. Each module performs a specific function, making the overall complex system manageable through functional segmentation
Solution Approach 2:
The controller acts as an intermediary between the sensors and the notification system, processing sensor data and determining when and how to display status information. This intermediary layer simplifies the interaction between different system components
3Loss of time
If visual notification systems are added to indicate component status, then caregiver response time improves, but device complexity increases
Solution Approach 1:
The notification system uses different colors of LED indicators to communicate different status conditions (e.g., green for normal, yellow for warning, red for error). This color-coding system provides intuitive visual information without requiring complex displays or interfaces
Solution Approach 2:
The system creates visual copies or representations of the actual component statuses through iconic representations on the display. Instead of showing raw sensor data, the system displays simplified visual icons that represent the state of various components, making information more accessible
