Visual Alert Device with Color-Coded Priority Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospital caregivers and food preparers face challenges in timely follow-up due to distractions from busy environments, leading to potential lapses in critical care and food overcooking, as existing audible timers are often disregarded amidst ambient noise.
Innovation Solution
A visual alert device with illuminable identifiers of different colors (green, yellow, red) that indicate the progressive expiration of a predetermined time period, coupled with a controller, numeric keypad, and attachment options like a spring-biased clip and magnet for versatile mounting, to provide a visual reminder of response priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If audible timers are used to notify caregivers of follow-up times, then the alert can be heard across the hospital environment, but the alerts are easily drowned out by ambient noise and caregivers become desensitized to them
Solution Approach 1:
The patent replaces the acoustic alert mechanism with an optical/visual alert mechanism. Instead of using audible timers that emit sound waves to notify caregivers, the system uses visual identifiers (LEDs or other illuminable elements) that display color-coded time remaining indicators. This substitution eliminates the problem of ambient noise drowning out alerts while maintaining effective notification across the hospital environment.
Solution Approach 2:
The patent employs color changes in visual identifiers to convey different levels of time remaining and urgency. The system displays different colors (e.g., green, yellow, red) representing different time intervals before follow-up is due, allowing caregivers to quickly assess priority at a glance without being affected by ambient noise conditions.
2Loss of information
If multiple color segments are illuminated to indicate progressive time expiration, then response priority levels are clearly communicated, but device complexity increases
Solution Approach 1:
The patent divides the visual identifier into multiple color segments (e.g., green, yellow, red portions) that can be independently illuminated. Each segment represents a specific time interval or priority level. This segmentation allows the system to convey detailed time priority information through simple, discrete visual states rather than requiring complex continuous displays or multiple separate indicators.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures timely attention to patients and food monitoring by visually representing response priority levels, reducing the risk of overcooking and care lapses through a clear, attention-grabbing visual alert system that can be mounted in various locations.
Implementation Method 1
a magnet, thus allowing the visual alert device to be mounted in a variety of locations
Implementation Method 2
A controller, which also includes a timer, is coupled to the illuminable identifier

AI summary
A visual alert device includes a keypad for a user to enter a primary follow-up time period for which a user desires to be visually reminded of its progressive expiration. Based on the entered primary follow-up time period, the visual alert device computes a preliminary and a final follow-up time value, which are associated with a level of response priority that is visually represented by the illumination of corresponding illuminable color segments. Thus, when a timer of the visual alert device reaches each of the preliminary follow-up time value, the primary follow-up time period, and the final follow-up time value, the corresponding color segments are illuminated to indicate the current response priority level.
