Solution Overview

Problem

Current mobile device-based badge systems require close proximity to scanning devices for verification, which can compromise social distancing and security, especially during pandemics or high-security situations, and lack effective measures to prevent fraud and unauthorized access.

Innovation Solution

A dynamic badge system on mobile devices that allows scanning at a distance using a changing object shape over time, combined with health assessment checks to ensure authorized access, and incorporates social distancing measures like staggered entry times to reduce contact and infection spread.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If mobile device badges are scanned at close proximity to ensure detailed verification, then measurement precision is improved, but social distancing and security are compromised

Engineering Contradiction:
Improvebadge verification accuracyVSAvoidcontact risk and security vulnerability
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent transitions the scanning system from 2D close-proximity scanning to 3D depth-aware scanning using time-of-flight sensors. By adding the depth dimension, the system can verify badges at a distance while maintaining accuracy through spatial information about the badge's position and orientation in 3D space.

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

Solution Approach 2:

The patent replaces the mechanical requirement of physical proximity with an optical/electromagnetic field-based time-of-flight scanning system. This substitution allows the scanning device to capture detailed badge information through light time measurements without requiring physical contact or close proximity, thereby eliminating the harmful contact factor.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If scanning distance is increased to enable social distancing, then contact risk is reduced, but measurement precision and security verification deteriorate

Engineering Contradiction:
Improvecontact riskVSAvoidbadge scan accuracy
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent substitutes traditional optical scanning with time-of-flight (ToF) sensing technology that actively measures the time for light to travel to the badge and back. This allows the system to maintain measurement precision at increased distances by using temporal measurements rather than relying solely on optical resolution, enabling social distancing without sacrificing verification accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the measurement parameter from spatial resolution alone to time-based distance measurement. By measuring the time of flight of light signals, the system can accurately determine badge characteristics at greater distances, transforming the limitation of distance into a measurable parameter that enhances both safety and accuracy.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If static badge images are used for access control, then ease of operation is improved, but fraud prevention and security are weakened

Engineering Contradiction:
Improvebadge display simplicityVSAvoidfraud prevention capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent transforms the static badge image into a dynamic verification process. The badge displayed on the mobile device remains simple for the user, but the scanning system captures multiple frames over time and uses temporal analysis to verify authenticity. This dynamic approach maintains ease of operation while significantly improving fraud prevention through motion-based verification.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements periodic scanning where the system captures multiple images of the badge at different time points. This periodic action allows the system to verify that the badge is a live, dynamic display rather than a static photograph, enhancing security while keeping the user interface simple and easy to operate.

Inventive Principle:
Principle #19Periodic action

AI summary

Systems and methods for displaying a dynamic badge for accessing a facility are disclosed. The dynamic badge may include a display of one or more objects that change shape over time according to a predetermined pattern. The dynamic badge may visible at a specified distance (such as a social distancing limitation). The dynamic badge may be scanned or recognized by a scanning device at the specified distance to determine facility access for a user of the badge.
