Building Access System Using Wireless Transceivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access systems for buildings lack effective security measures to prevent misuse of keys and ensure rapid emergency access, particularly in scenarios where unauthorized access or key compartment tampering can occur.
Innovation Solution
The access system incorporates a publicly accessible key compartment with a transceiver that communicates identification codes to building door transceivers, utilizing radio frequency identification (RFID) or active wireless communication, and includes emergency sensors that alert the control center for immediate response, along with sabotage detection to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key compartment is made publicly accessible with keys stored inside, then emergency access to the building is enabled, but the risk of key misuse and unauthorized access increases
Solution Approach 1:
The patent replaces the traditional mechanical key system with a wireless identification system. Instead of using physical keys that can be copied or misused, the system uses transceivers that communicate identification codes wirelessly through radio fields, eliminating the need for physical key handling and reducing misuse risks
Solution Approach 2:
The patent introduces a transceiver as an intermediary between the key compartment and the building door. The transceiver verifies identification codes before granting access, acting as a security gatekeeper that prevents unauthorized access even when keys are publicly accessible
2Ease of operation
If traditional mechanical keys are used in the key compartment, then simple access is provided, but security against unauthorized access and tampering is insufficient
Solution Approach 1:
The patent replaces mechanical locking systems with electronic transceivers that use wireless communication and identification code verification. This substitution maintains operational simplicity while significantly enhancing security through automated verification and tamper detection capabilities
Solution Approach 2:
The system incorporates feedback mechanisms where transceivers continuously monitor and verify identification codes, and sabotage sensors provide feedback about tampering attempts. This feedback loop ensures that access decisions are based on real-time security conditions, enhancing reliability
3Ease of operation
If the detection range of the transceiver is extended for easier key access, then accessibility is improved, but the risk of unauthorized communication and misuse increases
Solution Approach 1:
The patent applies local quality by creating a concentrated radio field with a specifically defined detection range around the building door transceiver. The field strength and detection capability are optimized locally at the door location rather than being uniformly distributed, ensuring that keys can only communicate with the authorized door and not with unauthorized receivers elsewhere
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures secure key access by limiting communication range, preventing misuse, and enabling rapid emergency access while detecting and responding to unauthorized attempts, thereby enhancing security and emergency response efficiency.
Implementation Method 1
At least one antenna of the transceiver advantageously generates at least one local radio field
Implementation Method 2
as soon as the passive radio card is in the local radio field, the coil inductively absorbs energy in the local radio field and the passive radio card is energetically activated

AI summary
The system has a transmitting-/receiving device i.e. printed circuit board assembly, provided in building doors (2, 2') i.e. access door, of a building (1). The transmitting-/receiving device receives an identification code of a key (4) when the key arrives in a detection area of the transmitting-/receiving device. A verification device verifies whether a valid access authorization for the building doors exists for the received identification code. A locking device unlocks the doors if the valid access authorization for the building doors exists for the received identification code. Independent claims are also included for the following: (1) a method for operating an access system for a building (2) a computer program product having a computer program unit to implement a method for operating an access system when the computer program unit is loaded in a processor of a transmitting-/receiving device and/or a verification device and/or key and/or a control device and/or a communication device (3) a computer readable data storage unit having a computer program product including a computer program unit to implement a method for operating an access system when the computer program unit is loaded in a processor of a transmitting-/receiving device and/or a verification device and/or key and/or a control device and/or a communication device.
