Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sequential transmission of signals through control devices is used, then device complexity is reduced, but transmission time and synchronization precision deteriorate
Solution Approach 1:
The patent divides the control functionality into multiple independent control devices (first control device 10, second control device 20, other second control devices 30) that operate in parallel. Each control device independently transmits control signals to its assigned memory units, eliminating the sequential bottleneck and reducing overall signal transmission time while maintaining manageable device complexity through functional segmentation.
Solution Approach 2:
The patent transitions from a single-dimensional sequential transmission path to a multi-dimensional parallel transmission architecture. Multiple control devices transmit signals simultaneously across different spatial paths to different memory units, adding dimensional complexity to the transmission topology but reducing temporal delays through concurrent operations.
2Speed
If multiple control devices transmit signals simultaneously, then signal transmission speed improves, but synchronization precision and signal integrity worsen
Solution Approach 1:
The first control device 10 performs preliminary actions by transmitting control signals to the second control device 20 and other second control devices 30 before these devices transmit to memory units. This staged preliminary transmission ensures that all control devices are synchronized and ready to transmit simultaneously, maintaining timing precision while achieving high-speed parallel transmission.
Solution Approach 2:
The patent implements feedback mechanisms where control devices monitor and adjust their signal transmission timing based on system state information. This feedback ensures that even with multiple devices transmitting in parallel, all signals arrive at memory units within the required timing window, maintaining synchronization precision despite increased transmission speed.
