Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mobile devices use only internal memory, then device complexity is low, but storage capacity is limited
Solution Approach 1:
The switching circuit enables the mobile device to perform multiple functions by dynamically reconfiguring connections. The same physical interface and memory system can serve both as internal memory (when connected to the processor) and as mobile storage (when connected to external interfaces), allowing one component to fulfill multiple roles based on operational needs
Solution Approach 2:
The patent implements a dynamic switching circuit that can change connection configurations in real-time. The circuit switches between different states to connect the memory system to either the processor (for internal memory operation) or external interfaces (for mobile storage operation), enabling the system to adapt its functionality dynamically rather than being fixed in one configuration
2Quantity of substance
If separate mobile storage devices are used, then storage capacity increases, but portability decreases
Solution Approach 1:
The patent combines the mobile storage functionality directly into the mobile device by integrating a switching circuit and memory system within the same device housing. This merging eliminates the need for separate external storage devices, as the mobile device itself can function as both a communication device and a mobile storage device, thereby maintaining portability while providing expanded storage capacity
3Adaptability or versatility
If data transfer between devices is required, then storage flexibility increases, but ease of operation decreases
Solution Approach 1:
The switching circuit is configured to automatically manage data transfer operations between the memory system and different components. When the memory system needs to transfer data, the switching circuit autonomously redirects connections between the processor and external interfaces without requiring manual user intervention to reconfigure hardware connections, thereby maintaining ease of operation while providing storage flexibility
