Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operation voltage level or environmental temperature changes, then the driving current changes, but the driving ability and electric performance of the memory array circuit deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where sensor signals detecting voltage and temperature variations are fed back to the compensation control module. This module processes the sensor signals along with control signals to generate compensation control signals that adjust the driving current, thereby maintaining stable electric performance despite environmental changes.
Solution Approach 2:
The patent changes the driving current parameter dynamically in response to detected voltage and temperature variations. The compensation driver module adjusts the driving current based on compensation control signals generated from sensor inputs, allowing the system to adapt to environmental changes while maintaining performance stability.
2Reliability
If a compensation mechanism is added to stabilize driving current, then the electric performance stability improves, but the device complexity increases
Solution Approach 1:
The patent segments the control system into distinct functional modules: a control module for generating control signals, a driver module for providing driving current, a sensor module for detecting environmental variations, a compensation control module for processing signals, and a compensation driver module for adjusting current. This modular segmentation organizes the complexity into manageable, independent units.
Solution Approach 2:
The patent introduces intermediary components between the sensor module and the driver module to mediate the compensation process. The compensation control module acts as an intermediary that receives sensor signals and control signals, processes them, and generates compensation control signals that are then transmitted to the compensation driver module for current adjustment.
