Luminous Barrier Windows for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems in restricted areas fail to provide precise visual identification of user categories within the gated area, leading to delays and stoppages, as they do not visually follow user movement and often incorrectly identify authorized users due to the presence of unauthorized 'tailgaters' or 'piggy-backers'.
Innovation Solution
A control and monitoring system that uses a processing unit connected to a user authentication device and an image capture device to activate luminous elements on barriers, creating indicative windows of specific colors for authorized, unauthorized, and special users, which follow the users' movements within the gated area, facilitating quick identification by security agents and controlling the blocking device's opening or closing based on user movement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional access control systems use blocking devices without visual tracking, then the system structure is simpler, but security personnel cannot quickly and accurately identify unauthorized users
Solution Approach 1:
The patent applies color-coded luminous elements that change color based on user authentication status. Authorized users are indicated by green light, unauthorized users by red light, and special users by yellow light. This color-change mechanism enables security personnel to quickly and accurately identify user categories at a distance, resolving the contradiction between identification accuracy and system complexity by using intuitive visual coding rather than complex display systems
Solution Approach 2:
The patent introduces luminous elements as an intermediary between the authentication system and security personnel. These luminous elements act as a visual mediator that translates authentication data into intuitive color signals, allowing security personnel to identify unauthorized users without requiring complex visual displays or close proximity to the authentication devices
2Reliability
If the blocking mechanism closes immediately upon detecting unauthorized users, then unauthorized access is prevented, but authorized users may be blocked due to tailgating
Solution Approach 1:
The patent applies dynamic control to the blocking mechanism, allowing it to adjust its state based on real-time visual identification of user categories. The blocking device can selectively close for unauthorized users (red indicator) while maintaining openness for authorized users (green indicator), enabling dynamic response that prevents unauthorized access without unnecessarily blocking authorized users
Solution Approach 2:
The system implements feedback through continuous visual monitoring of user categories and real-time adjustment of blocking device state. The luminous elements provide ongoing feedback to both the control system and security personnel, enabling the blocking mechanism to respond appropriately to different user scenarios and maintain both security and flow efficiency
3Loss of information
If visual indicators are added to track user movement, then security personnel can identify unauthorized users, but the system requires additional equipment
Solution Approach 1:
The patent applies multi-functionality to the luminous elements, which serve multiple purposes: they provide visual identification of user categories, guide user flow, and enable real-time monitoring without requiring separate equipment for each function. The same luminous elements that indicate authorized users also serve as part of the blocking mechanism control system, reducing overall equipment quantity while maintaining comprehensive information tracking

Function Achieved in This Case
Enables fast and precise identification and segregation of unauthorized or special users, ensuring unhindered access for authorized users by providing real-time visual identification and adaptive control of the blocking device's operation, reducing delays and flow stoppages.
Implementation Method 1

AI summary
We describe a control and monitoring system and method for access to a restricted area, such as mass transport systems (subways, trains, airports, ships and others), commercial buildings, schools, factories, datacenters, and other places with people moving, composed of a Processing Unit (10) that receives information both from a User Authentication Device (20) and an Image Capture Device (40). The Processing Unit (10) processes this information determining user category as well as user location, speed and direction of movement within a Gated Area (GA). In turn, the Processing Unit (10) triggers one or more Bars of Luminous Elements (31) arranged in Barriers (30) limiting a Gated Area (GA), giving every user (Authorized User [AU], Unauthorized User [UU] or Special User [SU]) a User Category Window (311, 312 or 313) that follows the movement of the user within the Gated Area (GA). A Blocking Device (50) can be activated by the Processing Unit (10) to be partially or fully closed or opened and at a speed proportional to the location, velocity and direction of movement of the user within the Gated Area (GA).
