Solution Overview
Problem
Existing electronic key systems for secure access to electronic cylinders have fixed access profiles, making them inflexible for users who need to access multiple locations, and require physical programming, which limits interoperability and is inconvenient for traveling users.
Innovation Solution
An electronic key with a memory, microprocessor, wireless communication module, and optional global positioning module that allows real-time management of access profiles via a server, enabling remote updates and dynamic authorization based on location and time parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic keys use fixed access profiles programmed locally, then security is maintained through controlled access codes, but flexibility and adaptability for traveling users deteriorate
Solution Approach 1:
The patent implements dynamic access profiles that can be remotely updated in real-time. The electronic key receives updated authorization data via wireless communication (GSM/GPRS/UMTS) from a remote server, allowing access rights to change dynamically based on user needs, location, and time without requiring physical reprogramming or fixed pre-programming.
Solution Approach 2:
The patent introduces a remote server as an intermediary between the key management system and the electronic key. This server acts as a mediator that stores access profiles and communicates with the electronic key via wireless communication modules, enabling flexible remote updates while maintaining centralized security control.
2Ease of manufacture
If electronic keys require physical programming devices, then access codes can be changed, but interoperability and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical physical programming device with an electronic wireless communication system. Instead of requiring physical contact between programmer and key, the system uses wireless communication modules (GSM/GPRS/UMTS) to transmit programming data remotely, eliminating the need for specialized physical programming equipment and improving interoperability.
Solution Approach 2:
The patent makes the electronic key universally programmable through wireless communication. The key can receive programming data from any location via standard wireless communication protocols, making it compatible with multiple systems and eliminating the need for device-specific physical programmers, thereby enhancing interoperability across different platforms.
3Reliability
If access profiles are fixed in key memory, then security is maintained through stored authorization data, but real-time management and remote control deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the electronic key communicates with the remote server via wireless communication. The key can send status information and receive updated access profiles in real-time, allowing the system to monitor and control access dynamically. This feedback loop enables remote management while maintaining security through verified authorization data.
Solution Approach 2:
The patent pre-loads access profiles into the key's memory before they are needed, but these profiles can be remotely updated. The wireless communication module receives updated authorization data in advance of when it might be needed, allowing the system to prepare and implement security changes proactively while maintaining real-time remote management capability.
