Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hardwired communication infrastructure is used between code entry module and controller, then reliable signal transmission is achieved, but security vulnerability increases due to physical access points
Solution Approach 1:
The patent replaces the mechanical hardwired communication system with a wireless communication system. The code entry module communicates with the controller via wireless signals (radio frequency, infrared, or other wireless protocols) instead of physical cables, eliminating the physical attack vector while maintaining communication reliability through protocol-level security measures.
Solution Approach 2:
The patent introduces an intermediary encryption layer between the code entry module and controller. A secure communication protocol with encryption and authentication mechanisms is implemented, where the actual access code is transformed into an encrypted signal that requires cryptographic keys for decryption, adding a security intermediary that prevents direct interception.
2Ease of manufacture
If existing communication cabling is reused for security system installation, then installation cost is reduced, but security vulnerability persists
Solution Approach 1:
The patent eliminates the need to use existing communication cabling by implementing a wireless communication system. The code entry module and controller communicate through wireless signals, completely bypassing the physical cabling infrastructure and its associated security vulnerabilities, while keeping installation simple and cost-effective.
3Device complexity
If Wiegand protocol is used for communication, then simple one-way data transmission is achieved, but information security is compromised
Solution Approach 1:
The patent replaces the insecure Wiegand protocol with an intermediary encrypted communication protocol. The access code is encrypted using cryptographic algorithms (such as AES or RSA) before transmission, and the controller possesses the corresponding decryption key. This intermediary encryption layer maintains protocol simplicity while fundamentally improving information security.
Solution Approach 2:
The patent changes the fundamental parameter of the communication protocol from unencrypted to encrypted transmission. By implementing cryptographic transformation of the data stream, the protocol maintains its one-way transmission simplicity while adding layers of security through key-based encryption and authentication mechanisms.
4Object-affected harmful factors
If RS 485 protocol with encryption is used, then information security is improved, but installation complexity increases due to rewiring requirements
Solution Approach 1:
The patent replaces the RS 485 wired encrypted protocol with a wireless encrypted communication system. This substitution maintains the information security benefits of encryption while eliminating the need for complex physical rewiring, as wireless signals can be transmitted through existing spatial infrastructure without modifying building wiring.
Solution Approach 2:
The patent uses wireless communication as an intermediary medium to replace physical cabling. The encrypted data is transmitted through radio frequency or other wireless channels, serving as a mediator that provides both security and installation simplicity by bypassing the need for physical infrastructure modification.
