Identification Adapter for Wireless Retrofitting Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification devices for access control systems often require wired connections for data transmission, limiting the ability to retrofit them for wireless radio identification without modifying the control or reading units.
Innovation Solution
An identification adapter that converts wirelessly received identification data into a format compatible with the existing data communication connection between the reading and control units, allowing for seamless integration of wireless radio identification without altering the existing firmware or hardware of the control or reading units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an identification device uses a wired data communication link for data transmission, then system stability and compatibility are maintained, but the ability to support wireless radio identification is limited
Solution Approach 1:
An identification adapter is introduced as an intermediary device that bridges wireless identification data and the existing wired data communication link. The adapter receives wireless identification data, converts it to the appropriate protocol format, and transmits it through the existing wired connection to the control unit, thereby enabling wireless functionality without modifying the core system components.
Solution Approach 2:
The identification device is segmented into distinct functional modules: the existing reader与控制 unit remain unchanged, while a separate identification adapter handles wireless communication. This modular approach allows the wireless capability to be added independently without affecting the stability and compatibility of the original wired system.
2Adaptability or versatility
If the control unit or reading unit is modified to support wireless identification, then wireless radio identification capability is achieved, but system reliability and operational continuity are compromised
Solution Approach 1:
The identification adapter serves as a mediator that handles all wireless communication functions externally. By placing the wireless interface in the adapter rather than modifying the reader or control unit, the original system components maintain their proven reliability while gaining access to wireless identification through the adapter's conversion and translation capabilities.
3Adaptability or versatility
If data format conversion is implemented in the identification adapter, then compatibility with existing systems is maintained, but data transmission complexity increases
Solution Approach 1:
The identification adapter acts as a protocol translation intermediary that automatically handles data format conversion between wireless identification protocols and the existing wired communication protocol. This centralized conversion approach maintains system compatibility while consolidating complexity within the adapter module, leaving the reader and control unit simple and unchanged.
