Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 2D screen technology and camera control are used for AR/VR systems, then developers can create immersive environments, but users experience eye strain, headaches, and discomfort
Solution Approach 1:
The patent transitions from 2D screen display to 3D volumetric holographic display by rotating the display device around a central axis. Multiple 2D frames are projected at different angular positions (e.g., every 15 degrees around 360 degrees) to construct a three-dimensional volumetric image that users can view from multiple angles without wearing goggles, thereby eliminating the harmful effects of traditional VR/AR headsets while maintaining immersive capability
2Adaptability or versatility
If VR and AR goggles or headset systems are used, then electronic experience is improved, but programming difficulty, CPU usage, and manufacturing complexity increase
Solution Approach 1:
The patent extracts the display function from complex VR/AR headset systems and implements it using a simple rotating display device that can be integrated into everyday electronics like smartphones and tablets. This eliminates the need for specialized headset hardware, reducing manufacturing complexity and programming difficulty while maintaining the ability to create immersive holographic environments
Solution Approach 2:
The rotating display device can be integrated into various everyday electronic devices (smartphones, tablets, laptops, televisions) to create holographic displays. This universal approach allows a single technology platform to serve multiple functions across different device types, reducing the need for specialized VR/AR headset manufacturing and simplifying development across different platforms
3Object-affected harmful factors
If holographic display is implemented without additional goggles or headset systems, then user comfort is improved, but display technology complexity increases
Solution Approach 1:
The patent employs dynamic rotation of the display device at controlled speeds to create the holographic effect. The display rotates around a central axis, presenting different 2D frames at different angular positions, and uses temporal integration to create the perception of a stable 3D volumetric image. This dynamic approach achieves complex holographic display functionality through simple rotational motion rather than complex static optical systems
Solution Approach 2:
The display device rotates periodically around a central axis, presenting sequences of 2D frames at regular angular intervals (e.g., one frame every 15 degrees). This periodic rotation creates the holographic effect through temporal sampling, where the human visual system integrates the rapidly changing 2D displays into a persistent 3D volumetric perception, achieving complex display functionality through simple periodic motion

AI summary
A system for displaying a hologram includes a display assembly with a display device, and a motor coupled with the display assembly via a rotating anchor, the motor driving rotation of the display assembly and the display device from a first position to a plurality of positions around a complete rotation of the display assembly and the display device, the display device having a first display when in the first position and different displays when in the plurality of positions, such that the complete rotation of the display device causes the first display and the different displays to form the hologram.
