Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid crystal material is filled in the peripheral region, then the device structure is complete, but the liquid crystal material damages electronic circuits and has little effect on communication
Solution Approach 1:
The device is divided into a communication region and a peripheral region, with the liquid crystal layer selectively disposed only in the communication region. The protruding layer physically segments the space, preventing liquid crystal material from entering the peripheral region where electronic circuits are located, thus protecting the circuits while maintaining communication functionality.
Solution Approach 2:
The liquid crystal layer is extracted from the peripheral region and confined only to the communication region. The protruding layer serves as a barrier that removes the harmful liquid crystal material from the vicinity of electronic circuits, eliminating the damage risk while preserving the necessary communication function.
2Adaptability or versatility
If liquid crystal material is used for RF wave modulation, then communication function is achieved, but liquid crystal material in peripheral region has little effect and causes damage
Solution Approach 1:
The liquid crystal layer is localized only in the communication region where RF wave modulation is needed. The protruding layer creates a local quality difference by confining the liquid crystal material to specific areas, ensuring that the material performs its modulation function where required while being absent from regions where it would cause harm.
3Reliability
If protruding layer is added to protect circuits, then circuit reliability improves, but device structure becomes more complex
Solution Approach 1:
The protruding layer serves multiple functions simultaneously: it acts as a physical barrier to protect electronic circuits from liquid crystal damage, defines the boundary between communication and peripheral regions, and provides structural support for the liquid crystal layer. This multi-functionality reduces the need for additional separate protective components, thereby limiting the increase in device complexity.
