Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems are unable to implement situation-specific security policies and fail to prevent unauthorized access, particularly in man-traps, due to their inability to adapt to different security protocols and detect complex misuse situations such as tailgating and credential sharing.
Innovation Solution
A configurable access control device that includes a transit authorization request device, a presence detection and tracking device, and a control unit with a processing module and decision table, allowing for the assignment of virtual transit tickets and tracking of individuals to enforce customizable security policies, including detection of multiple persons and prevention of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional access control systems are used, then the system structure is simple, but the system cannot implement situation-specific security policies and cannot detect complex misuse situations
Solution Approach 1:
The access control system employs dynamic decision tables that can be configured and updated to adapt to different security policies and situations. The system transitions from static, fixed access control logic to dynamic, configurable decision-making processes that can respond to various misuse scenarios such as tailgating, credential sharing, and unauthorized access attempts.
Solution Approach 2:
The system changes parameters by allowing configurable decision tables with multiple input conditions and output actions. These decision tables can be adjusted based on different security policies, enabling the system to adapt to various situations without requiring complete system redesign, thus balancing adaptability with manageable complexity.
2Reliability
If sensing systems are added to detect misuse situations, then detection capability improves, but the system complexity increases
Solution Approach 1:
The sensing systems are designed with multi-functionality to detect various misuse situations including tailgating, credential sharing, unauthorized access, and more. By making the sensing system universal and capable of detecting multiple types of misuse through configurable decision tables, the system achieves high reliability without proportionally increasing complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where sensing data is continuously monitored and fed into configurable decision tables. This feedback loop enables the system to detect misuse situations in real-time and respond appropriately, improving reliability while maintaining manageable complexity through automated decision-making processes.
3Measurement precision
If presence detection and tracking devices are deployed, then the ability to track individuals and calculate occupancy improves, but the device complexity increases
Solution Approach 1:
The system replaces complex mechanical tracking mechanisms with optical sensing and image processing technologies. By using cameras and image analysis algorithms to track individuals and calculate occupancy, the system achieves high measurement precision while reducing mechanical complexity and enabling more accurate, non-intrusive monitoring.

AI summary
An access control device comprises at least one transit authorization request device, such as an ID sensor activated by access card or badge or a biometric sensor (fingerprint, retina), said transit authorization request device to be activated by a person requesting authorization to pass through said passageway or doorway and a presence detection and tracking device for detecting the presence of a person in the vicinity of said passageway or doorway and for tracking the movement of a person within or through said passageway or doorway. According to the invention, the access control device further comprises a control unit configured for assigning a virtual transit ticket to a person after authorization to pass through said passageway or doorway has been granted to said person, said virtual transit ticket being representative of the transit privileges granted to said person, i.e. the privileges regarding the transit direction through said passageway of doorway, and for controlling said presence detection and tracking device to track the movement of the person with the virtual transit ticket with respect to the granted transit privileges, said control unit comprising a processing module with a configurable decision table for generating an output control signal based on an output signal of said at least one transit authorization request device and an output signal of said presence detection and tracking device, said output control signal to be used for the controlling of the passage of persons through a passageway or a doorway.
