Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional stereoscopic display apparatus is used, then image quality and diagnostic accuracy are improved, but device size and portability are worsened
Solution Approach 1:
The patent implements nesting by placing the image display unit within the viewing box structure, where the display unit is integrated into the hollow space of the viewing box. This allows the display components to be contained within the overall device volume, achieving a compact portable design while maintaining stereoscopic image display capability for accurate medical diagnosis
Solution Approach 2:
The patent utilizes optical dimensionality by employing beam splitting and polarized light reflection to create three-dimensional stereoscopic images from two-dimensional display sources. The beamsplitter and reflection mirror system transforms the spatial arrangement of light paths, enabling depth perception and enhanced diagnostic accuracy without increasing physical device volume
2Measurement precision
If traditional stereoscopic display apparatus is used, then diagnostic capability is improved, but ease of operation and portability are worsened
Solution Approach 1:
The patent divides the stereoscopic display system into separable functional modules: a viewing box with adjustable viewing angles, an image display unit, and optical components (beamsplitter, reflection mirror). This segmentation allows the device to be compact and portable while maintaining full diagnostic capability when assembled, enabling doctors to easily transport and operate the system in remote areas
3Device complexity
If two-dimensional image display is used, then device simplicity is maintained, but diagnostic accuracy and stereoscopic visualization are worsened
Solution Approach 1:
The patent introduces optical intermediaries (beamsplitter and reflection mirror) between the image display unit and the viewer's eyes. These intermediary components transform ordinary two-dimensional display output into stereoscopic three-dimensional images by manipulating light paths and polarizations, enhancing diagnostic accuracy without requiring complex display hardware
