Light Adjustment Device Panel Unit Stacking Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light adjustment devices are larger in size due to the stacking configuration of substrates, which limits their compactness and efficiency.
Innovation Solution
A light adjustment device is designed with a panel unit formed in a rectangular column shape by stacking polygonal light adjustment panels, where each panel includes a first substrate, a second substrate, and a conductive member extending along the sides, allowing for electrical coupling at the corners, thereby reducing the overall size by making the substrates of equal size and optimizing the placement of terminals and sealing material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first substrate is made larger than the second substrate to provide exposed parts for terminals, then the terminals can be easily accessed and connected, but the overall device size increases when viewed in the stacking direction
Solution Approach 1:
The patent transitions terminal placement from a 2D surface arrangement (requiring large substrate area) to a 3D vertical arrangement (using the stacking direction). Terminals are positioned on the side surfaces of substrates at different heights, allowing electrical connection without increasing the horizontal footprint of the device.
Solution Approach 2:
The patent arranges substrates and terminals in a nested vertical configuration where the first substrate and second substrate are stacked, and terminals are positioned at different vertical levels. This nesting in the vertical dimension allows multiple terminals to be accommodated within the same horizontal space, reducing overall device volume.
2Reliability
If substrates are stacked with exposed edges for terminal placement, then electrical connections can be established, but the device occupies more space in the stacking direction
Solution Approach 1:
The patent utilizes the vertical stacking dimension to arrange terminals at different heights rather than spreading them horizontally. This dimensional transition allows electrical coupling to be achieved while minimizing the device's length in the stacking direction by compacting the vertical arrangement.
Solution Approach 2:
The patent combines the terminal placement function with the substrate stacking structure itself. Instead of adding separate terminal components that would increase length, the terminals are integrated into the stacked substrate arrangement, merging multiple functions into a compact configuration.

AI summary
A light adjustment device includes a panel unit formed in a shape of a rectangular column by stacking a plurality of light adjustment panels in a first direction, each of the light adjustment panels having a polygonal shape and including a first substrate and a second substrate, the first substrate including a first terminal, the second substrate overlapping the first substrate and including a second terminal, and a conductive member provided at a corner of the rectangular column in a side part of the panel unit and continuously extending in the first direction.
