Solution Overview
Problem
Conventional imaging devices and glasses struggle to provide clear images of objects at various distances, leading to indistinct vision and eye fatigue due to limited refractive correction range and the need for continuous lens adjustments.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed focal length lens is used, then the device complexity is reduced, but the imaging quality for objects at different distances deteriorates
Solution Approach 1:
The lens is divided into multiple subregions, each with independently adjustable imaging parameters. This segmentation allows different parts of the lens to optimize for different distances simultaneously, resolving the contradiction between fixed structure and variable imaging quality.
Solution Approach 2:
The lens transitions from a fixed focal length structure to a dynamic structure where subregions can independently adjust their imaging parameters based on object distance, enabling adaptive optimization without increasing overall structural complexity.
2Manufacturing precision
If multi-focus glasses with separate lenses for different distances are used, then the imaging quality for objects at different distances is improved, but the ease of operation deteriorates
Solution Approach 1:
Multiple focus functions are merged into a single lens through subregion segmentation. Each subregion handles different distance ranges, eliminating the need for users to switch between separate lenses or physically adjust the glasses position.
Solution Approach 2:
The lens automatically adjusts the imaging parameters of different subregions based on detected object distances, eliminating the need for manual user intervention. The system serves itself by autonomously optimizing imaging for each region.
3Manufacturing precision
If the lens focal length is continuously adjusted to track objects at different distances, then the imaging quality is improved, but the device complexity increases
Solution Approach 1:
Instead of continuously adjusting the entire lens, the lens is segmented into subregions that independently adjust their parameters. This reduces the complexity of the adjustment mechanism while maintaining high imaging quality across different distances.
Solution Approach 2:
Different subregions of the lens have locally optimized imaging parameters tailored to specific distance ranges. This local quality approach allows precise imaging control without requiring complex global adjustment mechanisms.
4Device complexity
If a single lens serves all distance ranges, then the device complexity is reduced, but the imaging quality for objects at extreme distances deteriorates
Solution Approach 1:
The lens is segmented into multiple subregions, each optimized for specific distance ranges. This maintains the simplicity of a single lens structure while achieving high imaging quality across extreme distances through localized parameter optimization.
Solution Approach 2:
A single lens structure achieves multi-functionality by enabling different subregions to handle different distance ranges simultaneously, combining the simplicity of a single lens with the performance of multiple specialized lenses.
