Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a telescope is attached to each lens in conventional spectacles to magnify images on the retina, then image magnification and recognition on defective retinal areas is improved, but the spectacles become cumbersome and bulky
Solution Approach 1:
The patent divides the telescope into multiple discrete lens elements (objective lens, eyepiece lens, and intermediate lenses) arranged in a segmented configuration. This segmentation allows each lens to be optimized for specific optical functions while reducing the overall bulk compared to a monolithic telescope design.
Solution Approach 2:
The patent employs a nested arrangement where multiple lens elements are positioned within compact spacing, with intermediate lenses nested between the objective and eyepiece lenses. This nesting approach minimizes the overall length and volume of the optical system while maintaining magnification functionality.
2Measurement precision
If a telescope is used to magnify images, then image recognition on low-resolution retinal areas is improved, but ray leakage occurs between lenses affecting image clarity
Solution Approach 1:
The patent extracts and removes the harmful effect of ray leakage by introducing light-blocking partitions between adjacent lens elements. These partitions selectively remove stray rays that would otherwise leak and cause image degradation, while preserving the useful light paths for image formation.
Solution Approach 2:
The patent introduces intermediate partitions as mediator elements between the lens components. These partitions act as intermediaries that control and manage light propagation, blocking harmful stray rays while allowing useful image-forming rays to pass through, thus mediating between the conflicting requirements of light transmission and ray leakage prevention.
3Measurement precision
If partitions are added between lens elements to prevent ray leakage, then image clarity is improved, but the fill factor decreases due to space occupied by partitions
Solution Approach 1:
The patent applies local quality by making the partitions selectively transparent or opaque only in the specific regions where ray leakage occurs, rather than making entire lens surfaces opaque. This allows the partitions to block harmful rays locally while maintaining high light transmission in the useful optical paths, thus preserving the fill factor.
Solution Approach 2:
The patent uses partial action by implementing partitions that block only the excessive stray rays rather than all light. The partitions are designed to provide just enough blocking to prevent ray leakage while allowing sufficient light transmission to maintain high fill factor and image brightness.
