Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control system is divided into multiple independent control modules, each responsible for controlling the gray scale of specific rhombic panels. This segmentation simplifies the control logic by breaking down the complex task of controlling multiple panels into smaller, manageable units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each rhombic panel can be controlled independently with its own gray scale settings, allowing localized optimization of display effects. The control system can adjust different regions differently to achieve desired patterns and stereoscopic effects.

Inventive Principle:

Solution Approach 1:

The display system is segmented into standardized hexagonal units, each containing three rhombic panels. This modular segmentation allows for standardized manufacturing and assembly processes, reducing the overall precision requirements compared to manufacturing a single large complex display structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rhombic panels are arranged in a specific asymmetric configuration within each hexagonal unit to optimize the display geometry and stereoscopic effects. This asymmetric arrangement within the symmetric hexagonal framework allows for precise visual alignment while maintaining manufacturing simplicity.
