Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing technologies are used to control internal operations, then the device structure remains simple, but the timing precision and control efficiency of internal operations deteriorate
Solution Approach 1:
The command generation is segmented into multiple independent circuits: a section signal generation circuit that divides operations into sections, and a mode command generation circuit that generates specific commands for each section. This segmentation enables precise timing control for each internal operation phase while keeping each individual circuit relatively simple.
Solution Approach 2:
A section signal is introduced as an intermediary between the oscillating signal and the mode command generation. The section signal generation circuit creates intermediate control signals that coordinate the timing of internal operations, acting as a mediator that translates the oscillating signal into precise operation timing without requiring complex direct control logic.
2Productivity
If existing technologies are used to generate mode commands, then the device complexity is low, but the control efficiency and performance of internal operations deteriorate
Solution Approach 1:
The control function is divided into specialized circuits: the section signal generation circuit handles timing division, while the mode command generation circuit handles command generation. This segmentation improves control efficiency by assigning specific functions to dedicated circuits, reducing the complexity of control logic in each circuit while enhancing overall productivity.
Solution Approach 2:
The section signal generation circuit performs preliminary action by pre-dividing the operation timing into sections before the mode command generation circuit creates specific commands. This preliminary timing division enables more efficient command generation and execution of internal operations.
3Manufacturing precision
If existing technologies are used to control internal operations, then the device structure remains simple, but the timing accuracy of mode operations deteriorates
Solution Approach 1:
The timing control is segmented into section signal generation and mode command generation stages. The section signal generation circuit divides the oscillating signal into precise time sections, and the mode command generation circuit generates commands synchronized with these sections, achieving high timing accuracy through multi-stage segmented control.
Solution Approach 2:
The section signal acts as an intermediary that carries precise timing information from the oscillating signal to the mode command generation circuit. This intermediary signal enables accurate timing synchronization without requiring complex direct timing control mechanisms.
