Tiled Light Transmitting Controller Multi-Zone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light transmitting controllers for smart windows face challenges such as inability to drive large-sized controllers in multiple zones, halo effects in the light transmitting state, and insufficient darkness in the dark state.
Innovation Solution
A tiled light transmitting controller is designed with multiple panels arranged between cover plates, allowing for multi-zone driving and improved light modulation to eliminate halo effects and enhance darkness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large-sized light transmitting controller is used, then the window area can be covered, but multi-zone control capability is lost
Solution Approach 1:
The patent divides a large window area into multiple independently controllable zones by using multiple light transmitting controller panels (first panel, second panel, third panel, fourth panel). Each panel can be controlled separately through independent control lines, enabling multi-zone control while covering the entire window area. This segmentation allows different zones to be controlled independently for optimized energy management and user convenience.
2Ease of manufacture
If conventional light transmitting controller design is used, then manufacturing is simple, but halo effects appear in light transmitting state
Solution Approach 1:
The patent applies local quality by implementing a border region around each light transmitting controller panel that has different optical properties from the central region. The border region (with width of 0.5-5cm) has modified light transmission characteristics that prevent halo effects, while the central region maintains good light transmission. This local differentiation eliminates the harmful halo effect without compromising overall manufacturing simplicity.
3Device complexity
If conventional light transmitting controller design is used, then structure is simple, but dark state lacks sufficient darkness
Solution Approach 1:
The patent enhances dark state performance by modifying the border regions of each panel to have superior light blocking characteristics compared to the central region. The border regions (0.5-5cm wide) are designed with enhanced optical properties that provide better darkness when the controller is in dark state, improving overall privacy and light blocking performance without significantly increasing structural complexity.
4Adaptability or versatility
If multiple panels are tiled together, then multi-zone control is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the window control system into multiple standardized panels that can be manufactured independently and then assembled together. Each panel has standardized dimensions and interface specifications, allowing modular manufacturing. The segmentation enables multi-zone control capability while managing manufacturing complexity through standardization and modular assembly processes.
Solution Approach 2:
The patent combines multiple independently controllable panels into a unified tiled system that functions as a single integrated window control solution. The panels are merged through standardized interfaces and control systems, creating a cohesive multi-zone control system that maintains the simplicity of individual panel manufacturing while achieving complex multi-zone functionality when assembled.

AI summary
A tiled light transmitting controller includes a first panel, a second panel, a first cover plate and a second cover plate. The second panel is electrically connected to the first panel. The second cover plate is arranged to be opposite to the first cover plate. The first panel and the second panel are arranged between the first cover plate and the second cover plate.
