Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional optical arrays are used to display holographic or floating 3D images, then the image quality and three-dimensional effect are improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent uses a 2D display screen to generate 3D visual effects by rapidly rotating the display at high speeds (e.g., 120 Hz or higher). The human visual system perceives the rotating 2D images as a floating 3D holographic image due to persistence of vision and stroboscopic effects. This copying approach creates the illusion of 3D without requiring complex optical arrays, thereby reducing device complexity while maintaining image quality.
Solution Approach 2:
The patent employs periodic rotation of the display screen at specific frequencies (e.g., 120 Hz, 240 Hz, or higher) to create the holographic effect. By synchronizing the rotation frequency with the display refresh rate and human visual perception thresholds, the system generates stable 3D images. This periodic mechanical action replaces complex static optical structures with a simpler dynamic system.
2Manufacturing precision
If sophisticated optical arrays are deployed for holographic display, then the three-dimensional imaging capability is enhanced, but the adaptability to different environments and use cases is reduced
Solution Approach 1:
The patent transforms a static display system into a dynamic one by implementing rapid rotation of the display screen. This dynamic approach allows the same hardware to adapt to different viewing conditions and environments. The rotation speed and synchronization can be adjusted based on ambient lighting, viewer distance, and desired image characteristics, providing versatility across various use cases without requiring environment-specific optical arrays.
Solution Approach 2:
The patent creates a universal holographic display solution using a standard 2D display screen that can function in multiple environments (indoor/outdoor, different lighting conditions, various viewing distances). The system achieves multi-functionality by combining simple mechanical rotation with software-controlled image rendering, eliminating the need for specialized optical components that would limit environmental adaptability.
3Ease of operation
If rapid rotation of the display screen is implemented to create floating image effects, then the visual immersion and interactivity are improved, but the risk of motion blur and image distortion increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and rendering multiple perspectives of the 3D object at different rotational positions before the actual rotation occurs. The system generates a sequence of 2D images that correspond to each angular position of the rotating display, ensuring that each frame is optimally rendered for its specific orientation. This pre-rendering approach prevents motion blur and maintains image clarity during rapid rotation.
Solution Approach 2:
The patent implements feedback mechanisms by using sensors (e.g., gyroscopes, accelerometers, encoders) to continuously monitor the actual rotational position and speed of the display screen. This real-time feedback is fed back to the control system, which adjusts the timing and content of displayed images to compensate for any deviations from the ideal rotation trajectory, thereby maintaining image clarity and preventing distortion during rapid rotation.

AI summary
According to one implementation, an image display system includes a computing platform having at least one processor and a system memory storing a software code. In addition, the image display system includes a display screen having a front display face and a side display face, and a base including a motor coupled to a rotor for rotating the display screen. The at least one processor executes the software code to render a two-dimensional (2D) graphic on the front display face of the display screen, and to render a visual effect on the side display face of the display screen. The at least one processor further executes the software code to use the motor and the rotor to spin the display screen to cause appearances of the 2D graphic as a floating image and the visual effect as a volumetric enhancement to the floating image.
