Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-layered lenses are assembled sequentially on a lens holder, then optical aberration can be eliminated, but the assembly process becomes tedious and coaxiality becomes difficult to maintain
Solution Approach 1:
The patent combines multiple lens layers into a single integrated lens structure with different refractive index regions, eliminating the need for sequential assembly of multiple separate lenses. This merging approach maintains optical aberration correction while simplifying the assembly process to a single unit installation.
Solution Approach 2:
The patent uses composite lens structure with regions of different refractive indexes within a single lens body, achieving multi-layered optical effects without requiring multiple separate lens components. This composite approach eliminates assembly complexity while maintaining the optical performance of multi-layered lenses.
2Reliability
If multi-layered lenses are assembled sequentially, then optical path control is achieved, but more space is required for assembly and the process is more tedious
Solution Approach 1:
The patent merges multiple lens layers into a single integrated lens structure, reducing the overall volume required for assembly from multiple separate components to one unified unit. The optical path control functionality is maintained within the single lens structure through strategic placement of different refractive index regions.
3Strength
If multiple adhesive materials are used to assemble multi-layered lenses, then adhesive force is increased to avoid ablation, but the assembly process becomes more complex
Solution Approach 1:
The patent eliminates the need for multiple adhesive materials by integrating all lens layers into a single monolithic structure. This merging removes the requirement for adhesives entirely, as there are no separate components to bond, thereby simplifying the assembly process while maintaining structural integrity.
4Manufacturing precision
If each lens is assembled separately to achieve high coaxiality, then optical axis deviation is avoided, but the assembly process becomes more tedious
Solution Approach 1:
The patent merges multiple lenses into a single integrated structure where coaxiality is inherently ensured by the manufacturing process of the unified lens. This eliminates the need for complex alignment procedures required when assembling separate lenses, as the single lens structure guarantees optical axis consistency throughout.

Implementation Method 1
a first portion and a second portion having a first light condensing effect... the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect
Implementation Method 2
the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect, and then pass through the first light absorption curve to form a second light condensing effect

AI summary
A lens structure formed by materials in different refractive indexes includes a transparent sphere in a first refractive index as well as a transparent second lens in a second refractive index. The first refractive index is different from the second refractive index, and the sphere is a round ball formed by a first portion and a second portion which are equipped with a first light condensing effect. The first lens is formed on the first portion of the sphere, the second portion of the sphere is exposed out of the first lens, and the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect, and then pass through the first light absorption curve to form a second light condensing effect.
