Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrode lines are used in dynamic glazing, then the device can achieve transparency switching, but the electrode lines are prone to breaking during manufacturing and use, reducing manufacturing yield and device lifetime
Solution Approach 1:
The electrode is divided into multiple parallel lines that are electrically connected through transverse connections, forming a mesh structure. This segmentation means that if one line breaks, the others can still function, thereby improving reliability and manufacturing yield without compromising the transparency switching capability.
2Manufacturing precision
If conventional electrode configurations are used, then the device can switch between transparent and opaque states, but the electric field distribution is non-uniform, affecting the homogeneity of the glazing appearance
Solution Approach 1:
Transverse connections are added between parallel electrode lines to equalize the potential distribution across the electrode structure. This ensures uniform electric field distribution and homogeneous glazing appearance while maintaining a manageable structure through systematic connection patterns.
3Speed
If the glazing transitions between opaque and transparent configurations, then the optical properties change, but the transition speed is non-uniform across the glazing surface, creating visual inconsistencies
Solution Approach 1:
The mesh electrode structure with transverse connections ensures that all regions of the glazing receive uniform electric field strength simultaneously, causing the charged particles to move at uniform rates across the entire surface, thereby achieving uniform transition speed without complex control systems.

AI summary
Some embodiments are directed to a light modulator comprising transparent or reflective substrates, multiple electrodes being applied to the substrates in a pattern across the substrate. A controller may apply an electric potential to the electrodes to obtain an electric field between the electrodes providing electrophoretic movement of the particles towards or from an electrode, wherein the electrodes are multiple interlaced mesh electrodes (210, 230) comprising multiple main lines (211, 212, 213, 214, 215) being connected to other multiple main lines through multiple interconnections (221, 241, 242, 222, 223, 243).
