Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical element uses a fixed orientation, then the device complexity is reduced, but the three-dimensional image recognition quality deteriorates due to inability to adapt to varying user positions
Solution Approach 1:
The optical element's inclination angle is made dynamically adjustable rather than fixed. The control unit varies the inclination angle of the optical element according to the detected eye positions, allowing the system to adapt to different user positions and viewing conditions without requiring multiple fixed configurations.
Solution Approach 2:
The system changes the inclination angle parameter of the optical element based on detected eye positions. By dynamically adjusting this geometric parameter, the optical element can optimize light beam direction for different user positions, improving three-dimensional image recognition quality without adding complex mechanical structures.
2Reliability
If the optical element is fixed in orientation, then the manufacturing process is simplified, but crosstalk increases due to suboptimal light beam direction control
Solution Approach 1:
The optical element is designed with adjustable inclination capability, allowing optimization of light beam direction to minimize crosstalk between left and right eye images. The control unit dynamically adjusts the inclination angle based on eye positions, ensuring optimal image quality without requiring multiple pre-configured optical elements.
Solution Approach 2:
A single optical element is designed to perform multiple functions by adjusting its inclination angle to different positions. This universal optical element can serve various viewing conditions and user positions, replacing the need for multiple specialized optical elements with different fixed orientations.
3Measurement precision
If multiple optical element configurations are used to adapt to different user positions, then the three-dimensional image recognition quality improves, but the device complexity and cost increase
Solution Approach 1:
Instead of using multiple fixed optical elements, the system employs a single optical element with dynamic inclination adjustment. The control unit receives eye position detection data and dynamically adjusts the optical element's angle, achieving adaptive optimization without the complexity of multiple configurations.
Solution Approach 2:
The optical element system automatically adjusts its inclination angle based on detected eye positions without requiring manual reconfiguration or multiple pre-set configurations. The control unit autonomously varies the optical element's orientation to match user eye positions, enabling the system to serve different viewing conditions self-adaptively.

AI summary
A three-dimensional display system includes a display panel, an optical element and a controller. The display panel includes an active area configured to display a parallax image. The optical element defines a light beam direction of the parallax image. The controller is configured to vary the parallax image based on positions of first and second eyes of the user. The optical element includes a plurality of optical means which are arranged in a parallax direction. The plurality of optical means extend along an inclination direction inclined to a reference direction with respect to a direction perpendicular to the parallax direction. The reference direction is defined, at least in a standard state, based on at least one of a position of the user in the parallax direction in an interior of the moving body and a position relative to the user of a predetermined facility mounted within the moving body.
