Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If electrical signals are used for data transfer in memory modules, then the device structure remains simple and power consumption is low, but the data transfer rate is limited
Solution Approach 1:
The patent replaces the electrical signal transmission system with an optical signal transmission system. Specifically, it uses an optical detector to convert external input optical signals into internal input electrical signals, and an optical generator to convert internal output electrical signals into external output optical signals. This substitution of electrical signals with optical signals enables significantly higher data transfer rates while maintaining the fundamental memory module structure.
Solution Approach 2:
The patent changes the fundamental parameter of signal transmission from electrical to optical domain. By using optical signals instead of electrical signals for data transfer between the memory module and external devices, the system achieves much higher transmission speeds. The optical detector and optical generator enable this parameter change while maintaining compatibility with existing electrical interfaces through signal conversion.
2Productivity
If optical signals are used for data transfer, then the data transfer rate increases significantly, but the device complexity increases due to additional optical components
Solution Approach 1:
The patent integrates multiple functions into the controller, which not only manages the memory chip operations but also coordinates the optical detector and optical generator. The controller serves as a universal management unit that handles both electrical memory operations and optical signal conversion coordination, reducing the need for separate dedicated control circuits for each function.
Solution Approach 2:
The optical detector and optical generator act as intermediary components that bridge the optical external interface and the electrical internal memory system. These intermediaries enable seamless signal conversion without requiring complete system redesign, allowing gradual integration of optical technology into existing memory architectures.
3Reliability
If power is supplied from external power supply only, then the device structure is simple, but data loss occurs during power failures
Solution Approach 1:
The patent incorporates a built-in battery that is charged in advance during periods when external power is available. This preliminary charging action ensures that sufficient energy is stored before a power failure occurs, enabling the memory module to complete data operations and maintain data safety during unexpected power interruptions.
Solution Approach 2:
The built-in battery serves as a cushioning energy source that protects against power failures. By having this backup power source prepared in advance, the system can withstand external power disruptions without losing data or requiring complex real-time power switching mechanisms.
