Solution Overview

Problem

Current optical image stabilization technologies in camera devices struggle to effectively compensate for camera shake during photography, leading to blurred images due to hand shake or environmental limitations.

Innovation Solution

The proposed solution involves an image sensor anti-shake component with a simple and reliable structure, comprising a fixed component, a rotating component, a movable component, and a drive component. The drive component includes a coil and a permanent magnet that rotate relative to each other, allowing the image sensor to rotate relative to the fixed component along a specific plane, thereby compensating for camera shake.

1Reliability

If the image sensor is moved to compensate for camera shake, then the anti-shake function is improved, but the structural complexity increases

Engineering Contradiction:
Improveanti-shake functionVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anti-shake component is divided into distinct functional modules: a fixed component providing stable support, a rotating component carrying the image sensor, a movable component enabling rotation, and a drive component actuating the rotation. This segmentation allows each module to be optimized independently while maintaining overall system reliability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic anti-shake compensation by enabling the rotating component to rotate relative to the fixed component around an optical axis. The movable component facilitates this rotation through controlled movement, allowing the image sensor to dynamically adjust its position to compensate for camera shake in real-time.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the rotating component is axially fastened to the fixed component, then the motion stability is improved, but the ease of manufacture decreases

Engineering Contradiction:
Improvemotion stabilityVSAvoidassembly
Core Design Contradiction:

Solution Approach 1:

The fastening mechanism is segmented into axial fastening features that connect the rotating component to the fixed component. This segmentation allows for standardized manufacturing of individual components while ensuring stable axial connection, balancing manufacturing ease with motion stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The movable component serves as an intermediary between the fixed component and the rotating component, facilitating their connection and enabling controlled rotation. This intermediary structure simplifies the overall assembly process while maintaining the required motion stability for anti-shake operation.

AI summary

An image sensor anti-shake component includes a fixed component, a rotating component, a movable component, and a drive component. The fixed component includes a base, a cover, and a first circuit board. The rotating component includes a rotating platform, a second circuit board, and an image sensor. The movable component is connected to the fixed component and the rotating component such that the rotating component is axially fastened. When the drive component drives the rotating component to move, the rotating component can only rotate relative to the fixed component and cannot move. The drive component includes a coil and a permanent magnet that are in a one-to-one correspondence.
