Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional optical systems use thicker structural parts to maintain mechanical strength, then structural strength is improved, but device miniaturization is hindered

Engineering Contradiction:

Improvemechanical strengthVSAvoidoptical system size

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The patent merges the lens holding member with the substrate by molding the lens holding member directly on the substrate, creating an integrated structure. This eliminates the need for separate mounting components and reduces overall optical system volume while maintaining structural strength through the unified design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lens assembly is nested within the lens holding member, which itself is integrated with the substrate. This nested arrangement allows compact positioning of optical components close to the substrate, minimizing the distance between elements and reducing the overall optical system volume.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of moving object

If conventional optical systems reduce structural part thickness for miniaturization, then device size is reduced, but mechanical strength deteriorates

Engineering Contradiction:

Improveoptical system sizeVSAvoidmechanical strength

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The patent uses a molded lens holding member that integrates multiple functional elements into a composite structure. This composite design allows thin structural parts to achieve sufficient mechanical strength through the combined functionality of different integrated components rather than relying on individual thick parts.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The lens holding member is molded directly on the substrate in advance, creating a pre-integrated structure that provides mechanical strength from the outset. This preliminary integration ensures that structural strength is built into the design before assembly, allowing thin components to work together effectively.

Inventive Principle:

Principle #10Preliminary action

3Strength

If conventional optical systems maintain designated thicknesses for mechanical strength, then structural strength is ensured, but ease of manufacture for mass productivity is reduced

Engineering Contradiction:

Improvemechanical strengthVSAvoidmass productivity

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The lens holding member is molded directly on the substrate as an integrated structure, combining multiple manufacturing steps into one. This merging of components simplifies the manufacturing process, reduces assembly operations, and improves ease of manufacture for mass production while maintaining structural strength through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If conventional optical systems use separate mounting structures for lens assembly, then ease of assembly is improved, but device complexity increases

Engineering Contradiction:

Improveease of assemblyVSAvoidoptical system structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The lens holding member integrates the mounting function directly into the substrate structure, eliminating separate mounting components. This merging reduces the number of parts and simplifies the overall optical system structure while maintaining ease of assembly through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)
