Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the bracket is designed to be thick to meet structural strength requirements, then the structural strength is improved, but the camera module cannot be miniaturized and there is a mismatch with the lens assembly

Engineering Contradiction:

Improvestructural strengthVSAvoidcamera module size

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The bracket is constructed using a composite structure combining metal and plastic materials. The metal portion (first bracket) provides structural strength and electromagnetic shielding, while the plastic portion (second bracket) reduces overall weight and size. This composite approach resolves the contradiction by achieving sufficient strength with a thinner, more compact design.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The bracket is divided into two distinct parts: a metal first bracket for structural support and electromagnetic shielding, and a plastic second bracket for mounting electronic components. This segmentation allows each material to perform its optimal function while reducing the overall bracket thickness and enabling camera module miniaturization.

Inventive Principle:

Principle #1Segmentation

2Strength

If the bracket is designed to be thick for structural strength, then the structural strength is improved, but the imaging quality deteriorates due to interference with electronic components

Engineering Contradiction:

Improvestructural strengthVSAvoidinterference with electronic components

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The metal first bracket provides electromagnetic shielding to protect electronic components from interference, while the plastic second bracket isolates components physically. This composite structure simultaneously achieves structural strength and reduces electromagnetic interference with electronic components.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The plastic second bracket acts as an intermediary between the metal first bracket and the electronic components, providing electrical isolation and physical mounting while preventing direct contact that could cause interference or short circuits.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Volume of moving object

If the bracket height is reduced for miniaturization, then the camera module size is reduced, but the structural strength deteriorates

Engineering Contradiction:

Improvecamera module sizeVSAvoidstructural strength

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The metal first bracket provides high strength-to-weight ratio, allowing reduced bracket height while maintaining structural strength. The plastic second bracket adds minimal height for component mounting. Together they achieve miniaturization without sacrificing structural integrity.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The metal portion is strategically positioned to provide structural strength where needed, while the plastic portion is used where weight reduction and component mounting are priorities. This local differentiation of material properties enables miniaturization while maintaining strength.

Inventive Principle:

Principle #3Local quality
