Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network capacity is increased to meet growing digital networking demand, then user capacity constraint is reduced, but service provider costs increase
Solution Approach 1:
The system implements self-service through automated service usage monitoring and billing processes. The service provider system automatically tracks resource consumption, generates usage records, and processes billing without requiring manual intervention, thereby reducing operational costs while maintaining high network capacity
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring service usage and providing real-time information about resource consumption patterns. This enables dynamic resource allocation and optimization, allowing the network to efficiently manage capacity while controlling costs through data-driven decisions
2Reliability
If secure execution environment is implemented for DDR processing, then device-based access policies are secured, but device complexity increases
Solution Approach 1:
The system segments the device architecture by implementing a dedicated secure execution environment that is separated from the main processor operations. This secure enclave is specifically designed for DDR processing and access control functions, isolating critical security operations from the rest of the system to enhance security without significantly complicating the overall device structure
Solution Approach 2:
The secure execution environment acts as an intermediary between the processor and the access policy enforcement mechanisms. It serves as a trusted mediator that verifies and enforces access policies without requiring the main processor to directly handle security-critical operations, thereby simplifying the integration of security features into the existing device architecture
