Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic locks use software-level security measures, then ease of operation is improved, but reliability is worsened due to susceptibility to hacking and security breaches
Solution Approach 1:
The patent replaces software-level security with hardware-level security by embedding cryptographic processing units and secure key storage directly in the electronic lock device. This hardware-based approach uses cryptographic operations and secure element integration to resist hacking and security breaches while maintaining ease of operation through contactless interfaces.
Solution Approach 2:
The patent employs a composite security architecture combining multiple security layers including cryptographic algorithms, secure key storage, hardware security modules, and encrypted communication protocols. This multi-layered composite approach ensures both ease of operation and high reliability by preventing single-point failures and security breaches.
2Device complexity
If electronic locks rely on a single communication protocol, then device complexity is reduced, but reliability is worsened due to single points of failure
Solution Approach 1:
The patent implements multiple communication protocols (Bluetooth, Wi-Fi, Zigbee) with different operational parameters and encryption methods. Each protocol can operate independently or in combination, allowing the system to adapt to different communication environments and maintain reliability even if one protocol fails or is compromised.
Solution Approach 2:
The patent segments the communication system into independent protocol modules, each handling specific communication tasks. This modular segmentation allows individual protocols to be activated or deactivated based on requirements, reducing the impact of single-point failures while managing overall system complexity through organized module structures.
3Reliability
If electronic locks use traditional key systems as backup, then reliability is improved during power failure, but ease of operation is worsened due to key loss and theft risks
Solution Approach 1:
The patent replaces traditional mechanical key systems with contactless authentication methods including biometric sensors, NFC tags, and cryptographic verification. These hardware-based contactless methods eliminate key loss and theft risks while providing reliable backup access during power failures, improving both ease of operation and security.
Solution Approach 2:
The patent creates digital copies of authentication credentials stored in secure hardware elements within the lock device. These cryptographic copies can verify user identity without physical keys, enabling reliable backup access methods that are as secure as the primary electronic system and equally easy to operate.
4Reliability
If electronic locks implement comprehensive security monitoring, then reliability is improved, but device complexity increases due to multiple security layers
Solution Approach 1:
The patent merges multiple security functions (cryptographic processing, key storage, authentication verification, communication encryption) into an integrated hardware security module. This consolidation reduces device complexity by combining security layers into a unified system while maintaining comprehensive security monitoring and high reliability through coordinated function execution.
