Infant Care Station Wall Latch Detection Using Image Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infant care stations, such as incubators and radiant warmers, often have walls that can be propped up in an unlatched position, posing a risk of accidental opening and potential harm to neonates due to inadequate protection or exposure to external conditions, as existing indicators may be overlooked by caregivers.
Innovation Solution
A patient safety monitor system using image sensors and spatial relationship analysis, including machine learning models, to determine whether the walls of infant care stations are latched by comparing captured images to industry norms, and providing alerts through user interfaces if the walls are unlatched.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional latch indicators are used, then the device complexity is low, but the reliability of detecting unlatched walls is insufficient because indicators may be overlooked by caregivers
Solution Approach 1:
The patent replaces traditional mechanical latch indicators with an optical imaging system using image sensors (cameras) to capture and analyze wall positions. This substitution enables more reliable detection through visual analysis while maintaining reasonable system complexity through the use of standard imaging components and processing algorithms.
Solution Approach 2:
The patent introduces an intermediary image analysis system that captures images of the infant care station walls and processes them to determine latch status. This intermediary layer between the physical latch mechanism and the caregiver provides more reliable detection by translating physical positions into visual information that can be accurately analyzed and communicated.
2Measurement precision
If image sensors and spatial relationship analysis are used, then the measurement precision of wall position is improved, but the device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent creates a visual copy (image) of the physical wall positions using image sensors, and then analyzes this copy to determine latch status. This copying approach enables precise measurement of wall positions without requiring direct physical contact sensors, thereby improving measurement precision while keeping the sensor system relatively simple.
Solution Approach 2:
The patent replaces complex mechanical position sensing mechanisms with optical imaging and computational analysis. By using image sensors to capture wall positions and applying spatial relationship analysis algorithms, the system achieves high measurement precision without the complexity of dedicated mechanical sensors for each wall.
3Reliability
If manual monitoring of latch status is used, then the ease of operation is high, but the reliability of safety monitoring is insufficient
Solution Approach 1:
The patent implements an automated feedback system that continuously monitors wall positions using image sensors, analyzes the images to determine latch status, and provides immediate feedback to caregivers through alerts or indicators. This feedback loop ensures reliable safety monitoring without requiring manual checking, as the system automatically detects and communicates unlatched conditions.
Solution Approach 2:
The patent enables the infant care station to self-monitor its own latch status through integrated image sensors and processing systems. The system automatically captures images, analyzes wall positions, determines latch status, and generates alerts without human intervention, thereby improving safety monitoring reliability while maintaining ease of operation through automated functionality.

AI summary
A system for determining a state of an infant care station includes an image sensor through which a first image is captured, a computer processor, and a memory device. The memory device includes instructions executable by the computer processor to determine, based on the first image, a first spatial relationship between a first predetermined point of a first feature that is captured in the first image, and a second predetermined point of a second feature that is captured, and a second spatial relationship between the first predetermined point of the first feature and a third predetermined point of a third feature that is captured. Additionally, the instructions are executable to determine the state of the infant care station based on the first and second spatial relationships. The state of the infant care station indicates whether the walls of the infant care station are latched.
