Location-Based Risk Evaluation for Event Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workplace safety systems are often ineffective against unknown threats and are not designed to mitigate generalized risks such as the spread of infectious diseases, making them inadequate for proactive health risk analysis and mitigation.
Innovation Solution
A method and system that calculate location and personnel risk characteristics to assess event risk, compare it to a risk acceptability threshold, and implement risk mitigation policies, such as altering event schedules or locations, to manage potential health risks without specific knowledge of a contagion or its symptoms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing workplace safety systems are used to monitor employee movements and detect unsafe behaviors, then specific safety compliance can be improved, but the systems are ineffective against unknown threats and cannot mitigate generalized risks such as infectious disease spread
Solution Approach 1:
The risk evaluation system is designed to perform multiple functions: it calculates location risk characteristics based on visitor history, identifies various types of events, calculates personnel risk characteristics based on attendee numbers, and generates comprehensive risk assessments. This multi-functional approach allows the same system to address both specific known threats and generalized unknown threats like infectious diseases, thereby resolving the contradiction between reliability for known threats and adaptability for unknown threats
2Reliability
If comprehensive risk evaluation is performed by calculating location risk characteristics, personnel risk characteristics, and event risk, then proactive health risk mitigation is improved, but system complexity increases
Solution Approach 1:
The risk evaluation system is divided into distinct modular components: a location risk characteristics calculator that processes visitor history, an event identifier that detects various events, a personnel risk characteristics calculator that analyzes attendee numbers, and an event risk calculator that synthesizes these inputs. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable, maintainable, and scalable while achieving comprehensive proactive risk mitigation
3Reliability
If risk mitigation policies are implemented based on calculated event risk compared to risk acceptability threshold, then workplace safety is enhanced, but operational flexibility may be reduced
Solution Approach 1:
The risk mitigation system dynamically adjusts policies based on real-time risk assessments. The system calculates event risk by combining location risk characteristics with personnel risk characteristics, compares the result against a risk acceptability threshold, and automatically implements appropriate mitigation policies. This dynamic approach allows the system to enhance workplace safety while maintaining operational flexibility, as policies are adjusted based on actual risk levels rather than being statically applied

AI summary
An event at a location is identified. An event risk of the event can be calculated based on risk characteristics of both the location of the event (“location risk characteristics”) and the event itself (“personnel risk characteristics”). Location risk characteristics can include a visitor history of the location. Personnel risk characteristics can be based on attendees of the event, such as a number of attendees. The overall event risk, once calculated, can be compared to a threshold. Depending on the comparison, a risk mitigation policy can be implemented.
