Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single optical system is designed to display larger floating images, then the image size increases, but the manufacturing cost and system volume increase significantly
Solution Approach 1:
The patent divides the floating display system into multiple independent optical units, each responsible for a portion of the final image. Instead of using one large optical system, multiple smaller optical units work together to form the complete floating image, reducing the manufacturing complexity and cost of individual optical elements while achieving a large overall display area.

Solution Approach 2:
The patent integrates multiple optical units within a compact arrangement where they share common structural support and control systems. The optical units are positioned and configured to overlap their fields of view, creating a nested or interlocking structure that reduces the overall system volume compared to a single large optical system.
3Adaptability or versatility
If different optical systems are designed for different image sizes, then the adaptability to various application scenes improves, but the device complexity and resource consumption increase
Solution Approach 1:
The patent designs each optical unit to be a standardized, interchangeable module that can be configured in different quantities and arrangements to achieve various floating image sizes. This universal modular design allows the same basic optical unit to serve multiple functions across different application scenarios, reducing the need for multiple specialized optical systems and lowering overall device complexity.
