Coded Visitor Access Control Without Wired Intercom Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intercom systems for managing access to premises are time-consuming, expensive, and require complex wired installations, while also compromising resident privacy and security due to the need for visible resident lists and frequent maintenance.
Innovation Solution
A method utilizing a support for coded information, a mobile visitor terminal, and a computer server to manage access, eliminating the need for wired connections and allowing secure, discreet communication and door control through encrypted data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional intercom system with wired connections is used, then secure communication between visitor and resident is achieved, but installation becomes time-consuming, expensive, and complex
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system using mobile terminals and coded information. The visitor terminal reads coded information from a support structure and communicates with the resident terminal via wireless networks, eliminating the need for physical cable installations between the street panel and indoor handsets.
Solution Approach 2:
The patent introduces coded information as an intermediary element displayed on a support structure near the entrance. This coded information serves as a mediator that enables the visitor terminal to identify and establish communication with the correct resident terminal without requiring direct wired connections or a traditional street panel with resident lists.
2Ease of operation
If a traditional intercom system with resident lists is used, then visitor can select resident for communication, but resident privacy and security are compromised
Solution Approach 1:
The patent uses coded information that represents the premises and enables resident identification without displaying actual resident identities. The coded information acts as a copy or representation that allows the selection function to work while protecting the original resident privacy information from being exposed to passers-by.
3Reliability
If wired intercom systems are installed in large premises, then communication reliability is improved, but installation cost and maintenance requirements increase
Solution Approach 1:
The patent replaces the mechanical wired communication infrastructure with wireless communication technology. Mobile terminals communicate with each other and with the coded information support structure using wireless networks, eliminating the need for extensive cable installations throughout large premises while maintaining communication reliability.
4Reliability
If traditional intercom systems are deployed, then access control function is achieved, but regular maintenance is required
Solution Approach 1:
The coded information support structure is designed to be inherently maintenance-free. The support structure with displayed coded information requires no power supply, no software updates, and no technical maintenance. The system leverages the visitor's existing mobile terminal capabilities and wireless network infrastructure, eliminating components that would require regular maintenance.

AI summary
The method for managing access to a room containing a resident area (10), via a door (11), involves the use of a storage medium (12) for coded information (12'), and a resident terminal (10'). The method also involves the use of a mobile visitor terminal (13) configured to read the information (12'), and a computer server (14) storing resident data (10"). The computer server (14) communicates with the visitor terminal (13) and controls the opening of the door (11). The method comprises the following steps: - retrieving the coded information (12') by the visitor terminal (13) and then transmitting the coded information (12') to the computer server (14); - processing the coded information (12') by the computer server (14), and then transmitting the resident data (10") to the visitor terminal (13) in order to authorize the establishment of communication (15) with the resident terminal (10'); - allow the opening of the door (11) by the resident terminal (10').
