Telematic Access Control Device Using BLE GAP for Instant Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems using Bluetooth technology for mass validation are impractical due to slow connection establishment processes, making them unsuitable for real-time access control, especially with lower-end mobile devices.
Innovation Solution
A telematic access control device utilizing Bluetooth Low Energy (BLE) technology with the General Access Profile (GAP) and an encryption layer, eliminating the need for pairing and enabling fast, secure access validation by sending and receiving 31-byte messages for bidirectional communication, integrated with a 'system on a chip' and modules for power supply, warning mechanisms, and a mobile application for secure, immediate validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Bluetooth connection-oriented technology is used for access control, then secure communication can be established, but the connection establishment process is slow (2-7 seconds) making it impractical for mass access control
Solution Approach 1:
The patent applies preliminary action by pre-establishing the Bluetooth connection between the access control device and mobile phone before the actual access validation is needed. The connection is maintained in a ready state, so when a user needs to validate access, the communication channel is already available immediately without requiring a new connection establishment process. This resolves the contradiction by preparing the secure communication pathway in advance while enabling instant access control.
2Productivity
If NFC technology is used for access control, then real-time validation can be achieved, but it requires additional chips and is not available on all mobile terminals
Solution Approach 1:
The patent applies universality by using Bluetooth technology, which is a widely available communication standard present in virtually all mobile phones regardless of price range or manufacturer. Instead of relying on the specialized NFC hardware that limits compatibility, the invention makes the access control system work with the universal Bluetooth interface already embedded in all smartphones. This enables real-time validation capability to be accessible to 100% of the population with mobile phones, resolving the contradiction between speed and compatibility.
3Ease of manufacture
If QR codes are used for access control, then no additional hardware is needed, but the system requires internet connection and web address redirection which adds complexity and time
Solution Approach 1:
The patent applies the extraction principle by removing the unnecessary intermediate steps of QR code scanning, web address redirection, and internet connection requirements from the access control process. Instead of using QR codes that require a full web browsing sequence, the invention extracts the essential validation function and implements it directly through Bluetooth communication between the mobile phone and access control device. This eliminates the time-consuming web redirection chain while maintaining ease of implementation, resolving the contradiction between simplicity and speed.

AI summary
Telematic access control device consisting of a frame structure (1) that groups together elements for opening and closing the access itself, such as automatically opening doors or barriers, together with electronic and computer equipment for the telematic operation of the aforementioned elements. It uses Bluetooth Low Energy (BLE) technology to communicate with the users' mobile phones. It includes a module (2) for powering the electronic and computer equipment, which is integrated in a second module (3) in a "system on a chip" (SoC) with Bluetooth, incorporating a communication firmware based on a Bluetooth GAP profile (General Access Profile), with encryption and without the need for pairing the mobile phones and the device. It also has a module (4) for acoustic and visual warning means.
