Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple PROT connectors are installed on the motherboard to connect with multiple PROT units, then encryption protection coverage is improved, but hardware complexity and spatial demands increase
Solution Approach 1:
The single PROT connector is designed to support multiple PROT units through a universal interface that can dynamically connect to different functional units. The controller enables this connector to serve multiple encryption purposes by sequentially or selectively establishing communication channels with different PROT units based on system requirements, thereby achieving multi-functionality with a single connector.
Solution Approach 2:
Multiple PROT connectors and their associated communication interfaces are merged into a single PROT connector with enhanced controller functionality. The controller integrates the roles of multiple connectors by managing a single communication channel that can be dynamically allocated to different PROT units, reducing the total number of physical connectors while maintaining encryption coverage.
2Reliability
If multiple PROT connectors are installed on the motherboard to connect with multiple PROT units, then encryption protection coverage is improved, but spatial demands increase
Solution Approach 1:
The single PROT connector serves multiple PROT units through a universal interface design, eliminating the need for multiple separate connectors distributed across the motherboard. This multi-functional approach concentrates the connection interface in one location, significantly reducing the spatial footprint required for PROT connector deployment while maintaining comprehensive encryption coverage.
Solution Approach 2:
The physical connectors that would be distributed across the motherboard are merged into a single centralized PROT connector. This consolidation reduces the total area occupied by connectors and their associated routing, freeing up motherboard space while still providing encryption protection for multiple functional units through logical channel management.
3Reliability
If multiple PROT connectors are installed on the motherboard to connect with multiple PROT units, then encryption protection coverage is improved, but heat dissipation issues worsen
Solution Approach 1:
Multiple PROT connectors generating heat in different locations are merged into a single PROT connector with consolidated communication interfaces. This reduces the total heat generation points on the motherboard and concentrates thermal management requirements, making heat dissipation more manageable while maintaining encryption coverage for multiple functional units.
4Reliability
If multiple PROT connectors are installed on the motherboard to connect with multiple PROT units, then encryption protection coverage is improved, but electromagnetic compatibility issues worsen
Solution Approach 1:
Multiple PROT connectors with their associated electromagnetic emissions are merged into a single PROT connector with consolidated communication channels. This reduces the number of electromagnetic radiation sources on the motherboard, minimizing interference between adjacent connectors and improving overall electromagnetic compatibility while maintaining encryption protection for multiple functional units.
