Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing camera modules with anti-shake pan-tilt systems occupy large volumes, complicating hardware design and requiring significant space, and fail to effectively prevent image blur due to hand shake during shooting.

Innovation Solution

A camera module design featuring a housing with an accommodating cavity, a lens assembly, a circuit board, a support plate, and a drive assembly, where the support plate moves synchronously with the lens assembly and circuit board, driven by the drive assembly, reducing overall structure size and preventing pulling of the circuit board during movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large volume anti-shake pan-tilt system is designed, then image stability is improved, but device complexity and space occupation increase

Engineering Contradiction:
Improveimage stabilityVSAvoidhardware architecture design
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the lens assembly and circuit board onto a single support plate, making them move synchronously as one unit. This integration reduces the number of independent components and simplifies the overall hardware architecture while maintaining the anti-shake function that stabilizes the image during hand-held shooting or movement.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a large volume anti-shake pan-tilt system is designed, then image stability is improved, but the space occupied by the camera module increases

Engineering Contradiction:
Improveimage stabilityVSAvoidcamera module space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines the lens assembly and circuit board onto a single support plate, making them move synchronously as one unit. This integration reduces the number of independent components and simplifies the overall hardware architecture while maintaining the anti-shake function that stabilizes the image during hand-held shooting or movement.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If the lens assembly moves independently, then focusing is improved, but the circuit board may be pulled during movement

Engineering Contradiction:
Improvefocusing precisionVSAvoidcircuit board pulling
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The patent combines the lens assembly and circuit board onto a single support plate, making them move synchronously as one unit. This integration ensures that when the lens assembly moves for focusing or anti-shake compensation, the circuit board moves with it, eliminating the pulling effect on the circuit board while maintaining focusing precision.

Inventive Principle:
Principle #5Merging (Combining)
