Seamless Access Control Using RADAR-BLE Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems require active physical interaction from users to grant access, such as swiping or tapping credentials, which can be inconvenient and may lead to issues like tailgating.
Innovation Solution
A seamless access control system that utilizes RADAR and BLE technology to detect user presence, authenticate credentials, and determine intent, automatically unlocking barriers without manual user interaction, while monitoring for tailgating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic access control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mobile device that carries both the credential and the RADAR sensor. This mediator enables automatic credential transmission and intent detection without requiring direct interaction between the user and the access control system, thereby improving ease of operation while managing system complexity through a coordinated multi-component approach
2Device complexity
If manual credential interaction is required, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by continuously monitoring for authorized users approaching the access control device and pre-positioning the credential transmission before the user reaches the reader. This eliminates the need for manual interaction while maintaining manageable system complexity through automated background processes
3Ease of operation
If automatic access is granted, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the access control system continuously monitors user approach via RADAR, detects intent through credential transmission patterns, and adjusts access decisions accordingly. This feedback loop ensures that automatic access is granted only when appropriate, maintaining both ease of operation and security reliability
4Reliability
If intent detection is added, then reliability is improved, but device complexity increases
Solution Approach 1:
The mobile device serves multiple functions: it acts as a credential carrier, a RADAR sensor platform for intent detection, and a communication interface with the access control system. This multi-functionality enables enhanced security through intent detection while minimizing the increase in overall system complexity by consolidating multiple roles into a single device

Data Source
AI summary
A method for seamless access control according to one embodiment includes determining whether a user is authorized to access a passageway controlled by an access control device based on credential data received from a mobile device of the user, determining, by a RADAR system, a location of the user relative to the passageway, determining whether the user intends to access the passageway based on the determined location of the user relative to the passageway, and controlling, by the access control device, a lock mechanism to allow the user access to the passageway in response to determining that the user is authorized to access the passageway and the user intends to access the passageway.
