Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the visual distance between the book and eyes is extended to alleviate eye fatigue, then eye health is improved, but the text and image become less distinguishable and eyes fatigue easily unless magnification is applied
Solution Approach 1:
The patent introduces an optical module as an intermediary between the display module and the user's eyes. This optical module includes magnifying lenses that magnify the displayed content, allowing users to view text and images clearly at extended visual distances without compromising distinguishable ability. The intermediary optical system bridges the gap between the need for distance and the need for clarity.
Solution Approach 2:
The patent changes the optical parameters of the displayed content by using magnifying lenses with specific focal lengths. The optical module transforms the original display output into a magnified virtual image at a comfortable viewing distance. By adjusting the magnification parameter, the system enables clear viewing at extended distances, resolving the contradiction between distance and distinguishability.
2Object-affected harmful factors
If the visual distance is extended beyond 40 centimeters, then eye health is improved, but the distance exceeds the natural manipulation range of hands
Solution Approach 1:
The patent resolves the spatial contradiction by changing the dimensional relationship between the display and the user. Instead of requiring the user to reach forward to manipulate controls, the optical module creates a virtual image space at an extended distance while keeping the physical device within easy reach. The manipulation interface is positioned close to the user's hands, while the magnified content is projected at a comfortable viewing distance, separating the manipulation dimension from the viewing dimension.
3Volume of moving object
If the display module size is reduced to achieve thinness, then device portability is improved, but the image magnification capability is compromised
Solution Approach 1:
The patent segments the display system into two independent functional modules: a compact display module for generating the base image and an optical module for magnification. The display module can be made small and thin, while the optical module handles the magnification function. This segmentation allows each module to be optimized independently - the display module for miniaturization and the optical module for magnification capability.
Solution Approach 2:
The optical module serves as an intermediary that decouples the display module size from the final image magnification capability. The display module only needs to produce a small-resolution image, and the optical module magnifies it to the required size. This intermediary optical system enables thin, portable display devices to maintain strong magnification capabilities without increasing the display module volume.

Data Source
AI summary
A thinness screen magnification display device is provided and includes a processor, a display module electrically connected to the processor and an optical module. The processor is configured to receive an input image and to form an output image to display the output image on the display module. The optical module receives, reflects and magnifies the output image to form a projecting image. The processor extends the input image along the longitudinal direction to form the output image, and by the optical module, the magnifying scale of the output image in the longitudinal direction is greater than the magnifying scale of the output image in the transversal direction so that the aspect ratio of the projecting image is equal to the aspect ratio of the input image. By the two-stage magnification with the different magnifying scales, the size of the displaying device may be miniaturized, but the magnifying scale of the aspect ratio remains the same.
