Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conductive layers are placed adjacent to each other without insulation, then device complexity is reduced and manufacturing is simplified, but signal interference and noise increase
Solution Approach 1:
An isolation wire electrically insulated from other wires is introduced as an intermediary element between adjacent conductive layers. This isolation wire acts as a mediator that prevents direct electrical interference while maintaining spatial proximity for compact design, thus resolving the contradiction between simplified structure and signal interference prevention
2Ease of manufacture
If conductive layers are placed adjacent to each other without insulation, then manufacturing process is simplified, but risk of electrostatic discharge increases
Solution Approach 1:
The electrically insulated isolation wire serves as a protective intermediary between conductive layers, preventing electrostatic discharge while maintaining manufacturing simplicity. The isolation wire can be integrated into existing manufacturing processes and provides reliable electrical insulation without complicating the overall manufacturing approach
3Object-affected harmful factors
If isolation wires are added to electrically insulate conductive layers, then signal interference is reduced, but device complexity increases
Solution Approach 1:
The isolation wire is strategically positioned only where electrical insulation is critically needed between adjacent conductive layers, rather than uniformly across the entire device. This localized approach provides effective noise interference prevention while minimizing the increase in overall device complexity
4Reliability
If isolation wires are added to prevent electrostatic discharge, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The isolation wire is merged with the existing electrode structure and integrated into the same manufacturing process flow. The isolation wire can be formed using similar deposition and patterning techniques as the conductive layers themselves, allowing it to be manufactured concurrently without significantly increasing manufacturing complexity
