Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the same initialization potential is applied to all detection elements, then the initialization process is simple, but short circuits between adjacent detection elements cannot be accurately detected
Solution Approach 1:
The detection elements are divided into two groups (first detection elements and second detection elements) based on their column or row positions. Different initialization potentials are applied to each group, enabling differentiation between adjacent elements for accurate short circuit detection while maintaining a relatively simple initialization process.
2Measurement precision
If different initialization potentials are applied to adjacent detection elements, then short circuit detection accuracy is improved, but the initialization process becomes more complex
Solution Approach 1:
Different initialization potentials are applied locally to specific groups of detection elements (first detection elements in even-numbered columns or rows, second detection elements in odd-numbered columns or rows) rather than uniformly to all elements. This localized approach enables accurate short circuit detection while keeping the initialization circuit design manageable.
3Ease of manufacture
If all detection elements are initialized with the same potential, then the initialization circuit is simple, but quality control during manufacturing is compromised
Solution Approach 1:
Different initialization potentials are applied to different groups of detection elements before the actual detection process. This preliminary differentiation allows any short circuits that may have occurred during manufacturing to be detected in advance, ensuring device quality and reliability while maintaining a relatively simple initialization circuit structure.
