RGB LED Dome Light for Hospital Status Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hospital communication systems, including nurse call systems and point-of-care systems, face inefficiencies due to limited visual signaling capabilities of dome lights, which complicate the communication of patient and room status, especially when staff numbers are reduced, and require nurses to check into stations frequently for information.
Innovation Solution
A patient and room status display device utilizing a single RGB LED dome light capable of displaying multiple colors and patterns, combined with user-controlled actuators and a web-based interface, allows for efficient communication of status signals to hospital staff without the need for constant nurse station checks, ensuring patient privacy and adhering to HIPAA requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional dome lights with limited colors are used, then the device complexity is low, but the information communication capability is insufficient
Solution Approach 1:
The patent applies color changes by using an RGB LED that can display multiple colors (red, green, yellow, blue, and combinations) to represent different patient status signals. This allows a single dome light to convey diverse information such as patient comfort, hygiene needs, mobility status, and emergency conditions, thereby improving information communication capability without requiring multiple separate lighting devices.
Solution Approach 2:
The patent implements dynamics by enabling the dome light to change colors and illumination patterns dynamically based on real-time patient status data received from monitors and call systems. The lighting display adapts to varying conditions through programmed responses, allowing the system to communicate multiple status types through temporal and spectral variations in the light output.
2Productivity
If multiple status signals are conveyed through a single dome light, then the communication efficiency is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent applies periodic action by using flashing and pulsing light patterns to distinguish between different status signals. For example, steady light indicates one type of status while flashing light indicates another type. This temporal modulation allows the human eye to differentiate between multiple meanings conveyed by the same color, reducing the difficulty of detection while maintaining high communication efficiency.
Solution Approach 2:
The system uses distinct color combinations and intensity levels to represent different status categories. By leveraging human color perception and providing clear visual differentiation through color coding, the system makes it easier for staff to quickly identify and interpret multiple status types without confusion.
3Loss of information
If nurses check into station frequently to obtain patient information, then the information accuracy is improved, but the loss of time increases
Solution Approach 1:
The system enables self-service by providing real-time visual status information directly at the patient's bedside through the color-changing dome light. Staff can immediately see patient status updates without needing to return to the nurse station, allowing them to obtain accurate information instantly while minimizing time loss from frequent trips to the station.
Solution Approach 2:
The system implements feedback by continuously displaying updated patient status information on the dome light based on real-time data from monitors and call systems. This immediate visual feedback keeps staff informed of changing conditions without requiring them to check back at the station, reducing both time loss and improving information accessibility.
4Loss of information
If zone lighting with multiple LEDs is used, then the communication capability is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple LED functions (red, green, yellow, blue) into a single RGB LED dome light. Instead of using separate LEDs for different status indicators, the system merges all color capabilities into one unified lighting device, reducing the number of components while maintaining comprehensive communication capability for multiple patient status types.

Function Achieved in This Case
The solution provides a quick and efficient method for hospital staff to determine patient and room status, reducing the need for frequent nurse station checks and enhancing communication efficiency while maintaining patient confidentiality, by enabling multiple status signals to be conveyed through color and pattern changes on the RGB LED dome light.
Implementation Method 1
Each color represents a different status signal and is displayed by an RGB LED

AI summary
A patient and room status display device used to provide effective communication in healthcare environments. The display device uses a RGB (Red, Green and Blue) LED (Light Emitting Diode) to illuminate a dome light with any color, thus providing signals to healthcare workers representing different patient or room statuses. The display device can be operated through an external web-based interface, a nurse call master station or at least one user controlled actuator located on the display device. Each display device is mounted outside of every patient's room to provide multiple status signals for every patient in the hospital wing.
