Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If designated thicknesses of structural parts are required in the configurations of the existing optical systems for maintaining sufficient mechanical strength, then structural strength is maintained, but miniaturization becomes difficult

Engineering Contradiction:
Improvemechanical strengthVSAvoidsize of optical system
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The patent combines multiple structural functions into a single integrated support structure. The support structure simultaneously provides mechanical strength support, positions the lens assembly, and serves as a mounting platform for the diaphragm assembly, eliminating the need for separate structural components and reducing overall system size while maintaining required mechanical strength.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support structure is designed as a multi-functional component that performs multiple roles: it provides mechanical support, positions optical elements, supports the diaphragm assembly, and contributes to the overall structural integrity. This multi-functionality reduces the number of separate components needed, enabling miniaturization without compromising mechanical strength.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If conventional optical system configurations are used, then structural integrity is maintained, but miniaturization of electronic devices becomes difficult

Engineering Contradiction:
Improvestructural integrityVSAvoidsize of electronic device
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent employs a nested arrangement where the diaphragm assembly is positioned within the space defined by the support structure and lens assembly. The diaphragm assembly includes a diaphragm holder that is integrated into the support structure, creating a compact nested configuration that maintains structural integrity while minimizing the overall volume of the optical system.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent optimizes the spatial arrangement of components by utilizing three-dimensional space more efficiently. The support structure is designed with specific geometric features that allow components to be positioned in different spatial dimensions rather than simply stacking them linearly, achieving compactness without compromising structural integrity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
