Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical components are used to adjust light emission direction, then the emission direction can be adjusted, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical adjustment system with an optical system using liquid crystal. Instead of physically moving mirrors or lenses to change light direction, the invention uses liquid crystal molecules that can change their orientation based on applied voltage, thereby controlling light refraction direction without any mechanical moving parts.
Solution Approach 2:
The patent changes the physical state parameter of the liquid crystal molecules by applying voltage. When voltage is applied, the liquid crystal molecules transition from a non-tilted state to a tilted state, which changes the refractive index and thereby controls the light emission direction. This parameter change allows dynamic control without mechanical movement.

If mechanical components are used to adjust light emission direction, then the emission direction can be adjusted, but the configuration becomes complex
Solution Approach 1:
The patent replaces the mechanical adjustment system with an optical system using liquid crystal. Instead of physically moving mirrors or lenses to change light direction, the invention uses liquid crystal molecules that can change their orientation based on applied voltage, thereby controlling light refraction direction without any mechanical moving parts.
3Manufacturing precision
If liquid crystal molecules are tilted by applying voltage, then light refraction is improved, but the structural complexity increases
Solution Approach 1:
The patent divides the electrode structure into multiple independent electrode sets (first electrode sets and second electrode sets) arranged in specific patterns. Each electrode set can be independently controlled to tilt liquid crystal molecules in specific regions, allowing precise control of light refraction in different areas of the liquid crystal layer.
Solution Approach 2:
The patent applies voltage to specific electrode sets to create local tilting of liquid crystal molecules. By controlling which electrode sets receive voltage, the system can selectively tilt molecules in specific regions while leaving other regions unchanged, enabling precise spatial control of light refraction properties.

AI summary
A liquid crystal element includes first electrode sets disposed on a first substrate and each including a first electrode and a second electrode, second electrode sets disposed on a second substrate and each including a third electrode and a fourth electrode, a liquid crystal layer between the first and second substrates, and light-shielding films. The first and second electrodes in each first electrode set extend in a first direction and face each other in a second direction. The first electrode sets and the second electrode sets are arranged in the second direction. The first electrode included in one first electrode set overlaps the third electrode included in one second electrode set. The second electrode included in the one first electrode set overlaps the fourth electrode included in the one second electrode set. Each light-shielding film overlaps a gap between two first electrode sets adjacent in the second direction.
