Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lens devices are used without polarization structures, then the lens can maintain simple structure and manufacturing process, but the device lacks optical polarization function and cannot provide adequate eye protection
Solution Approach 1:
The lens is divided into multiple functional layers: a base lens layer and a polarization layer with miniature structures. This segmentation allows the polarization function to be added without completely redesigning the entire lens system, maintaining relative structural simplicity while achieving the desired optical polarization effect for eye protection
Solution Approach 2:
The invention combines conventional lens materials with polarization-functional miniature structures to create a composite lens system. The polarization layer is formed by integrating miniature structures into the lens material, creating a composite structure that provides both optical clarity and polarization functionality without requiring separate components
2Manufacturing precision
If traditional injection molding or press-molding methods are used for lens manufacturing, then the production process is straightforward, but these methods cannot form the required polarization miniature structures
Solution Approach 1:
The polarization miniature structures are formed preliminarily on a substrate before the final lens assembly process. By pre-forming the polarization layer with miniature structures and then bonding it to the base lens, the complex precision requirement is isolated to a separate manufacturing step, allowing the main lens production to remain simple while achieving high manufacturing precision for the polarization features
Solution Approach 2:
A separate polarization layer acts as an intermediary component between the base lens and the final assembled product. This intermediary layer carries the miniature polarization structures and can be manufactured independently using specialized techniques, then bonded to the conventionally manufactured base lens, thus decoupling the complex precision requirement from the overall manufacturing process
3Object-affected harmful factors
If the lens includes polarization structures, then eye protection and comfort are improved, but the overall thickness of the lens device increases
Solution Approach 1:
The polarization layer is designed as a thin film structure with miniature features rather than a thick bulk material. The miniature polarization structures are formed at micro-scale dimensions, allowing the polarization function to be achieved with minimal additional thickness. This thin-film approach provides adequate eye protection while minimizing the increase in overall lens thickness to maintain comfort

Function Achieved in This Case
The optical lens device achieves an optical grating structure for polarization, enhancing eye comfort and protection by generating a polarization effect through the miniature-structured polarization grating, while reducing the overall thickness of the lens device.

AI summary
An optical lens device includes an optical substrate layer, an optical polarization layer and a miniature surface structure. The optical substrate layer has a first surface and a second surface and rays of light passes through the optical substrate layer. The optical polarization layer is provided on the first surface or the second surface of the optical substrate layer. The miniature surface structure is physically processed to form the optical polarization layer and provides a characteristic of optical polarization in the optical polarization layer. The miniature surface structure of the optical polarization layer provides an optical polarization effect to the rays of light while passing through it.
