Population Stratification for Risk-Based Access Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently and reliably managing access control for large populations, particularly during infectious disease outbreaks, as determining individual health status and risk levels is time-consuming and unreliable.
Innovation Solution
A system and method for stratifying populations based on symptoms and risk factors using self-testing screening procedures, enabling dynamic communication and risk analysis to distribute customized access codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used to determine access status for each individual, then reliability can be maintained, but time consumption increases significantly and scalability is limited
Solution Approach 1:
The system enables individuals to self-assess their health status and risk level through automated questionnaires and algorithms. Users input their own health information, travel history, and symptoms, and the system automatically determines their access status without requiring manual verification by organizers, thereby increasing both speed and maintaining reliability through standardized criteria
Solution Approach 2:
The patent replaces manual mechanical assessment processes with automated computer-based systems. Instead of organizers manually evaluating each individual, the system uses software algorithms, databases, and automated communication protocols to assess health status and determine access rights, significantly improving throughput while maintaining consistency through programmed criteria
2Reliability
If comprehensive health screening is performed for all individuals, then reliability of risk assessment improves, but the process becomes time-consuming and not scalable to large populations
Solution Approach 1:
The system segments the population into different risk categories (low, medium, high risk) based on automated assessment criteria. Instead of applying the same comprehensive screening to all individuals, the system tailors the screening intensity to each segment's risk level, allowing rapid triage for low-risk individuals while reserving more thorough assessment for high-risk groups, thus maintaining reliability while reducing overall time consumption
Solution Approach 2:
The patent applies partial screening actions based on risk probability. For low-risk individuals, the system uses streamlined, lighter screening procedures that quickly confirm eligibility. For high-risk individuals, the system automatically triggers more comprehensive screening protocols. This differential approach ensures that comprehensive screening is applied only where necessary, maintaining assessment reliability while avoiding unnecessary time investment for low-risk populations
3Adaptability or versatility
If customized communication is delivered to each individual, then relevance and effectiveness improve, but system complexity and resource requirements increase
Solution Approach 1:
The system delivers localized, personalized communications to each individual based on their specific risk level, health status, and preferences. Instead of using a single uniform communication approach, the system tailors messages to local needs - providing detailed guidance to high-risk individuals while sending simplified information to low-risk groups. This customization is achieved through automated parameter adjustment rather than complex manual configuration, maintaining adaptability while managing system complexity through programming
