Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the number of lenses in the lens assembly is reduced to decrease module thickness, then the module thickness is reduced, but the imaging quality deteriorates due to insufficient light gathering and increased aberrations

Engineering Contradiction:
Improvemodule thicknessVSAvoidimaging quality
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

The patent changes the material parameter of the lens from conventional glass to plastic material, enabling the lens to achieve both thinness and high imaging quality. The plastic material allows for optimized refractive index and aberration control while maintaining a reduced number of lens elements, thus resolving the contradiction between reducing module thickness and maintaining imaging quality.

Inventive Principle:

2Use of energy by moving object

If the F-number is decreased to improve light gathering capability, then the light gathering capability is improved, but the depth of field is reduced and aberrations increase

Engineering Contradiction:
Improvelight gathering capabilityVSAvoiddepth of field and aberration control
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent optimizes the F-number parameter to achieve a balance between light gathering capability and depth of field. By carefully selecting and controlling the F-number along with the refractive index of the plastic lens material, the system achieves improved light gathering while maintaining adequate depth of field and controlling aberrations through the simplified single-element or few-element lens design.
