Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite the provision of material safety data sheets, accidents in laboratories still occur frequently due to the lack of effective data collection and processing systems for occupational safety and health, particularly in environments with hazardous substances.
Innovation Solution
A method is implemented to provide a user-optimized laboratory environment by receiving user location and experiment information, laboratory equipment location, and internal environment data from sensors, which is used to provide real-time and predicted environment information and control equipment such as fume hoods and air purification devices to prevent accidents and ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If material safety data sheets are provided to prevent accidents, then safety information is made available, but accidents still occur frequently due to lack of effective data collection and processing systems
Solution Approach 1:
The system continuously collects data from sensors monitoring laboratory conditions (temperature, humidity, gas concentrations) and provides real-time feedback to both the control system and users. This closed-loop feedback mechanism enables dynamic adjustment of environmental conditions and timely warning of hazardous situations, transforming static safety information into active, real-time safety management.
Solution Approach 2:
The laboratory environment monitoring system operates autonomously by automatically collecting data from multiple sensors, processing information, controlling equipment, and notifying users without requiring continuous human intervention. The system self-manages safety monitoring and environmental control, freeing users from manual safety management while maintaining high reliability.
2Loss of information
If multiple sensors are deployed to collect laboratory data, then data collection capability is improved, but system complexity increases
Solution Approach 1:
The control system serves multiple functions simultaneously: it collects data from diverse sensors, processes environmental information, generates safety warnings, controls laboratory equipment, and communicates with users. By consolidating these functions into a single integrated system, the patent reduces overall complexity compared to having separate systems for each function, while still benefiting from comprehensive multi-sensor data collection.
3Reliability
If real-time equipment control is implemented, then accident prevention is improved, but data processing requirements increase
Solution Approach 1:
The system extracts and processes only the critical information needed for safety monitoring and accident prevention from the vast amount of data collected by sensors. By filtering and selecting only essential parameters (such as hazardous gas concentrations, temperature extremes, and equipment status anomalies), the system reduces data processing requirements while maintaining high reliability in accident prevention.
