Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light adjustment panels are stacked and each coupled to a printed circuit board through a flexible printed circuit board, then each panel can be independently controlled, but the number of printed circuit boards increases leading to increased complexity and cost
Solution Approach 1:
Multiple flexible printed circuit boards are merged into a single printed circuit board by arranging terminal groups in a specific direction on the first substrate. The terminal groups are positioned such that multiple flexible printed circuit boards can be coupled to the same printed circuit board without overlapping, allowing multiple panels to be controlled through one consolidated printed circuit board rather than requiring separate boards for each panel.
2Ease of operation
If multiple flexible printed circuit boards are used for stacked panels, then each panel can be individually connected, but the number of components increases leading to higher cost
Solution Approach 1:
The invention consolidates multiple flexible printed circuit boards into a single printed circuit board by strategically arranging terminal groups on the first substrate. This arrangement allows multiple flexible printed circuit boards to be coupled to the same printed circuit board without overlapping, reducing the total number of components from multiple separate printed circuit boards to a single integrated board while maintaining individual panel connectivity.
3Ease of manufacture
If terminal groups are arranged in a direction parallel to the stacking direction, then connection is simplified, but flexible printed circuit boards would overlap when viewed from the stacking direction
Solution Approach 1:
The terminal groups are arranged asymmetrically in a direction intersecting the stacking direction (first direction) rather than parallel to it. Specifically, multiple terminal groups are arranged in a second direction that intersects the first direction when the panel unit is viewed in the first direction. This asymmetric arrangement prevents overlapping of flexible printed circuit boards while maintaining manufacturing simplicity.

AI summary
According to an aspect, a light adjustment device includes: a panel unit in which a plurality of light adjustment panels are stacked in a first direction, the light adjustment panels each including a first substrate and a second substrate, the first substrate including at least two terminal groups each including a plurality of terminals that are capable of being coupled to one flexible printed circuit board, the second substrate overlapping with the first substrate; and a plurality of flexible printed circuit boards each of which is coupled to one of the terminal groups of a corresponding one of the light adjustment panels. A plurality of the terminal groups are arranged in a second direction intersecting the first direction when the panel unit is viewed in the first direction, and the flexible printed circuit boards do not overlap with one another when viewed in the first direction.
