Solution Overview

Problem

Existing security measures in buildings and digital environments are inadequate in preventing contamination from individuals with diseases or health issues, as they often require close proximity for detection and lack effective remote screening and enforcement of access policies.

Innovation Solution

A system that utilizes offsite sensors to detect health characteristics, such as temperature, and integrates with access servers to dynamically control access to physical and digital environments based on health standards, enabling or disabling functionality as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If on-site security measures such as guards, locked doors, and access cards are used, then unauthorized access is prevented, but contamination from sick persons can still occur before access is denied

Engineering Contradiction:
Improveaccess control effectivenessVSAvoidcontamination risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs health screening (temperature detection) before granting access to physical locations or digital functionality. By detecting fever or other health indicators remotely via smartphone camera or wearable device, the system prevents sick individuals from entering buildings or accessing services, thereby eliminating contamination risk before it materializes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a digital intermediary layer (mobile application with health screening capability) between the individual and the physical/digital environment. This intermediary assesses health status and mediates access decisions, allowing remote enforcement of health policies without requiring physical presence of security personnel.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If thermal detectors are placed at access points, then fever detection is possible, but close spatial proximity is required allowing contamination before detection

Engineering Contradiction:
Improvefever detection capabilityVSAvoidcontamination spread
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system transitions from contact-based or close-proximity temperature detection to remote detection using smartphone cameras or wearable devices. By leveraging the camera's flash or sensor to detect thermal changes from a distance, the system maintains measurement precision while eliminating the need for close spatial proximity, thus preventing contamination spread.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If employees enforce sick leave policies, then access restrictions can be implemented, but employees are in poor position to evaluate customer health and may avoid confrontations

Engineering Contradiction:
Improvepolicy enforcement simplicityVSAvoidhealth evaluation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system enables self-service health screening where individuals use their own smartphone cameras or wearable devices to perform temperature checks and health assessments. The mobile application automatically evaluates health status and communicates access permissions, eliminating the need for employees to directly assess customer health or engage in confrontations while maintaining accurate health evaluation through objective measurements.

Inventive Principle:
Principle #25Self-service

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

Effectively prevents access and limits functionality for individuals not meeting health standards, enhancing safety and compliance with organizational policies without requiring on-site enforcement.

Implementation Method 1

Many sensors, such as thermal sensors, may require a close spatial range in order to detect certain characteristics (e.g., fever)

AI summary

The present disclosure includes embodiments for restricting or varying digital access or digital functionality based on health data. In one example, a method to vary functionality for an application is disclosed. The method includes receiving health data corresponding to a health status of a user, determining that the health status does not satisfy a health standard for an organization, and disabling at least one function for an application communicating with one or more devices of the organization based on the health status.
