Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a traditional sleeve is used to protect a mobile device, then the device is physically protected and battery life is extended, but computational power and secure environment capabilities remain limited
Solution Approach 1:
The patent combines a server, multi-core processor, memory, and crypto-unit within a single sleeve device, merging protective casing with computational and security functions. This resolves the contradiction by integrating multiple capabilities into one unit rather than requiring separate devices.
Solution Approach 2:
The sleeve is designed to perform multiple functions simultaneously: physical protection, battery extension, server operations, cryptographic authentication, and secure environment provision. This multi-functionality approach allows the single device to address computational power limitations while maintaining protective capabilities.
2Reliability
If a sleeve with server capabilities is added to provide secure environment and computational power, then security and processing abilities improve, but the sleeve size and complexity increase
Solution Approach 1:
The patent embeds a complete server system with multi-core processor and memory within the sleeve structure, nesting computational components inside the protective casing. This nesting approach provides secure environment capabilities while containing the complexity within a compact form factor.
Solution Approach 2:
The crypto-unit serves as an intermediary component that handles cryptographic operations and authentication, mediating between the server and external devices. This specialized intermediary module enhances security reliability while keeping the overall system architecture organized and manageable.
3Power
If the sleeve includes a multi-core processor and server to extend computational power, then processing capabilities increase, but energy consumption increases
Solution Approach 1:
The server within the sleeve operates periodically or on-demand rather than continuously, activating computational resources only when tasks require processing. This periodic operation pattern provides computational power when needed while minimizing energy consumption during idle periods.
Solution Approach 2:
The multi-core processor and server are designed to manage their own power consumption, with capabilities to enter low-power states and dynamically allocate resources based on workload demands. This self-service approach optimizes energy efficiency while maintaining computational capabilities.
