Engineering Contradiction Analysis
1Reliability
If conventional conductive substrates and electrode configurations are used, then the assembly structure is simple, but the switching efficiency between transmissive and reflective states is insufficient
Solution Approach 1:
The conductive substrate is segmented into multiple conductive elements arranged in parallel conduction paths between opposite surfaces. This segmentation allows distributed electrical contact with the electro-optic medium, improving switching efficiency without requiring a completely complex assembly structure.
Solution Approach 2:
The conductive elements are arranged in three-dimensional conduction paths extending through the thickness of the substrate. This dimensional arrangement enables efficient electrical connection to the electro-optic medium while maintaining structural simplicity.
2Adaptability or versatility
If conventional electrode configurations are used, then the manufacturing process is simple, but the performance and versatility of electro-optic media are limited
Solution Approach 1:
The conductive substrate with multiple conduction paths serves multiple functions: it provides electrical connection to the electro-optic medium, maintains structural support, and enables versatile applications including smart windows and augmented reality eyewear. This multi-functionality improves adaptability without significantly complicating manufacturing.
Solution Approach 2:
The configuration of conductive elements and conduction paths can be adjusted to optimize performance for different applications. By changing parameters such as the number, arrangement, and conductivity of elements, the system adapts to various electro-optic media requirements while maintaining manufacturability.
