Innovation Solution
A floating image display system that uses one or more display screens spun to generate a 3D effect, or a mirror facing the screen spun at an angle, along with a simple array of optical elements to project a 2D graphic as a floating image, allowing for the creation of immersive and interactive 3D imagery using readily available consumer electronics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sophisticated optical arrays are used to display holographic or floating images, then image quality and 3D effect are improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a 2D display screen as a simple copy or representation that, when rotated, creates the illusion of a 3D floating image. Instead of using complex optical arrays to generate true holographic images, the system projects a 2D graphic onto a rotating surface, leveraging human visual perception to interpret the rotating 2D image as a 3D object. This copying approach dramatically simplifies the optical system while maintaining the perceived 3D effect.
Solution Approach 2:
The patent introduces dynamic rotation of the display screen or mirror as the key mechanism to create the floating 3D image effect. By rotating the 2D display at controlled speeds and angles, the system dynamically generates different viewing perspectives that the human eye integrates into a perceived 3D stationary image. This dynamic approach replaces static complex optical arrays with a simple rotating 2D display, resolving the contradiction between image quality and device complexity.
2Adaptability or versatility
If sophisticated optical arrays are used for holographic display, then interactive 3D imagery is achieved, but ease of operation and accessibility to consumer electronics are reduced
Solution Approach 1:
The patent makes the floating 3D image technology universal by adapting it to work with common consumer electronics devices such as smartphones, tablets, and standard display screens. The system uses a rotating mirror or display mechanism that can be integrated with various existing devices, allowing interactive 3D imagery to be accessed through widely available consumer electronics rather than requiring specialized expensive equipment. This multi-functionality approach enables the same core technology to work across different device platforms.
3Device complexity
If rotating display screens or mirrors are used to generate floating images, then device complexity is reduced, but image stability and flicker reduction become challenging
Solution Approach 1:
The patent employs periodic rotation of the display screen or mirror at specifically controlled frequencies to generate the floating image effect. By rotating the 2D display in periodic cycles and synchronizing the rotation speed with the display refresh rate and human visual persistence, the system creates a stable perceived image that minimizes flicker. The periodic action ensures that each rotation cycle presents the correct 2D graphic orientation, and the human eye integrates these periodic presentations into a stable 3D image, resolving the stability challenge while maintaining simple device architecture.

AI summary
According to one implementation, a floating image display system includes a computing platform including a central processing unit (CPU), a graphics processing unit (GPU), and a system memory storing a software code. The system also includes one or more display screens controlled by the GPU, and a rotor coupled to the one or more display screens and controlled by the CPU. The CPU executes the software code to render a two-dimensional (2D) graphic on the one or more display screens using the GPU, and to spin the rotor and the one or more display screens about a vertical axis parallel to a display surface of the one or more display screens at a predetermined spin rate to generate a floating image of the 2D graphic. The floating image appears to be a three-dimensional (3D) floating image of the 2D graphic to a user viewing the floating image.
