Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive IT infrastructure cybersecurity approaches are applied to embedded devices, then security coverage is improved, but device complexity and processing requirements increase beyond what embedded devices can handle
Solution Approach 1:
The patent segments the embedded device into multiple security domains (e.g., critical control functions vs. non-critical functions) and applies different security measures to each domain. This allows comprehensive security coverage without requiring the entire system to meet high security standards, thereby reducing overall complexity while maintaining essential security protection.
Solution Approach 2:
The patent implements local quality by applying security measures selectively to specific components or functions based on their criticality. Critical functions receive enhanced security monitoring and validation, while non-critical functions use standard or reduced security measures, optimizing the balance between security and complexity.
2Reliability
If comprehensive IT infrastructure cybersecurity approaches are applied to embedded devices, then security coverage is improved, but processing power requirements exceed embedded device capabilities
Solution Approach 1:
The patent applies partial action by implementing security measures only where necessary based on risk assessment. Instead of applying comprehensive security to all functions, the system identifies critical security requirements and applies appropriate security controls only to those areas, reducing processing power consumption while maintaining essential security protection.
Solution Approach 2:
The patent changes security parameters dynamically based on operational context and risk levels. Security monitoring intensity, validation frequency, and control strictness are adjusted according to the criticality of operations and threat levels, allowing the system to maintain security protection while adapting processing power consumption to actual needs.
3Reliability
If cybersecurity measures are implemented on embedded devices, then vulnerability to cyber attacks is reduced, but cost and implementation complexity increase
Solution Approach 1:
The patent incorporates security measures during the design and development phases rather than adding them later. Security requirements are defined early, security domains are established during system architecture design, and security controls are integrated into the development process, reducing implementation complexity and cost while improving overall security effectiveness.
Solution Approach 2:
The patent employs universal security mechanisms that can be applied across multiple functions and components. By creating reusable security frameworks, validation routines, and domain definitions that work across different parts of the system, the patent reduces overall implementation complexity and cost while providing comprehensive security coverage.
