Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a planar image is displayed on a reflective display window, then the display system can be implemented with simple structure, but the visual experience and sense of presence are insufficient
Solution Approach 1:
The patent applies curvature to the display surface by generating a real image on a curved surface and using an optical imaging unit to create a curved virtual image. This curved image surface provides better visual experience and sense of presence compared to planar images, while maintaining compatibility with existing reflective display windows through optical path design
2Ease of manufacture
If a curved image surface is used to improve visual experience, then sense of presence and immersion are enhanced, but the optical path and imaging system become more complex
Solution Approach 1:
The patent introduces an optical imaging unit as an intermediary component between the image generation unit and the reflective display window. This unit includes optical elements that generate the curved real image and create the virtual image, serving as a mediator that transforms ordinary planar display into immersive curved display while managing the optical path complexity
3Ease of manufacture
If the display surface is made curved, then visual experience is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs parameter changes in the optical imaging unit to achieve curved image generation. By adjusting optical parameters such as focal length, curvature radius, and optical element positions, the system can generate curved virtual images with controlled precision, reducing the direct manufacturing precision requirements on the physical curved surface

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The curved virtual image improves user engagement and comfort by allowing viewing without line-of-sight movement, enhancing presence and immersion.
Implementation Method 1
the optical imaging unit is configured to perform imaging on the real image to generate an enlarged virtual image corresponding to the real image
Implementation Method 2
An imaging beam emitted from the image surface of the optical imaging unit is incident onto the reflective display window and is reflected by the reflective display window to eyes of a user
