Composite Optical Lens Dual-Sided Scratch Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional composite lens devices lack enhanced scratch resistance and effective protection on both sides, with existing technologies failing to provide uniform protection and optimal light transmission.
Innovation Solution
A composite high scratch-resistant optical lens device is developed, featuring a first and second scratch-resistant layer with structural reinforcement, a containing space layer, and an intermediate layer, where the scratch-resistant layers protect opposite sides of the space layer, and the intermediate layer can be an anti-reflection, polarization, or photochromic layer, integrated with the protective layers for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single protective layer is used on the lens, then the structure is simple, but the scratch resistance and protection on both sides are insufficient
Solution Approach 1:
The protective function is divided into multiple independent layers: a first protective layer on the front surface and a second protective layer on the rear surface. Each layer can be independently designed and optimized for its specific function, allowing the front layer to focus on scratch resistance while the rear layer addresses other protection needs, thereby resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent employs composite material structures where different materials are combined in multiple layers. The first protective layer may use materials optimized for scratch resistance (such as hard coatings or ceramic materials), while the second protective layer uses materials suited for rear surface protection. This composite approach enables each layer to contribute its specific material properties, achieving high reliability without excessive complexity.
2Reliability
If protective layers are added to both sides of the lens, then protection is improved, but light transmission may be compromised
Solution Approach 1:
Each protective layer is designed with specific local qualities optimized for its position and function. The first protective layer on the front surface incorporates properties for scratch resistance and optical clarity, while the second protective layer on the rear surface is optimized for its specific protection needs. By tailoring the material properties and optical characteristics to each local position, the patent achieves effective protection while minimizing impact on light transmission.
Solution Approach 2:
The patent optimizes parameters such as layer thickness, material composition, and optical properties to balance protection and light transmission. By carefully controlling the thickness of each protective layer and selecting materials with appropriate optical transmission characteristics, the patent achieves sufficient protection while maintaining high light transmission, resolving the contradiction between these two requirements.
3Adaptability or versatility
If uniform protection is provided on both sides, then symmetry is achieved, but the optimal protection degree for each side cannot be realized
Solution Approach 1:
The patent implements different protection degrees on the front and rear surfaces by providing a first protective layer with specific properties for the front surface and a second protective layer with different properties for the rear surface. Each layer is optimized for the specific protection needs of its location, allowing the front layer to provide high scratch resistance while the rear layer provides appropriate protection for that surface, thereby achieving adaptability without excessive complexity.

AI summary
A manufacturing method for optical lens devices includes: providing a first scratch-resistant layer on a first outer surface of a first protective layer having a structural reinforcement function to form a first reinforced protective layer; providing a second scratch-resistant layer on a second outer surface of a second protective layer having a structural reinforcement function to form a second reinforced protective layer; forming a containing space layer between a first inner surface of the first protective layer and a second inner surface of the second protective layer; providing an intermediate layer in the containing space layer; the first scratch-resistant layer and the first protective layer commonly protecting a first side of the containing space layer while the second scratch-resistant layer and the second protective layer commonly protecting a second side of the containing space layer.
