Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If P type and N type transistors are mixed used in exclusive-OR gate circuits, then the circuit functionality is achieved, but manufacturing complexity and costs increase
Solution Approach 1:
The patent applies homogeneity by using transistors of the same type (all P-type or all N-type) throughout the exclusive-OR gate circuit, eliminating the need to mix P-type and N-type transistors. This simplifies the manufacturing process and reduces device complexity while maintaining the required circuit functionality.
Solution Approach 2:
The patent changes the electrical parameters (voltage levels, current directions) to accommodate the use of identical transistor types. By adjusting these parameters, the circuit achieves the same logical functions as traditional mixed-type designs but with simplified manufacturing requirements.
2Ease of manufacture
If ten transistors of the same type are used, then manufacturing complexity is reduced, but circuit structure complexity increases
Solution Approach 1:
The circuit is segmented into multiple identical or similar transistor units (ten transistors of the same type) that perform specific functions within the overall exclusive-OR gate structure. This segmentation allows each transistor to be standardized while distributing the functional complexity across multiple identical components.
Solution Approach 2:
The patent merges multiple transistors of the same type into a unified circuit structure that collectively performs the exclusive-OR function. By combining identical transistor units in a specific configuration, the circuit achieves the required functionality while maintaining manufacturing simplicity.
