Solution Overview

Problem

Existing image-stabilization technologies in electronic devices, such as smartphones and tablets, only provide small-angle image stabilization using optical image-stabilization modules, failing to meet user demands for broader stabilization.

Innovation Solution

A dual image-stabilization mechanism is introduced, comprising a first motor to drive the lens and a second motor to drive the image sensor, utilizing coils and magnets to enable movement in multiple directions, achieving greater stabilization angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single optical image-stabilization module is used to move the lens, then small-angle image stabilization is achieved, but the stabilization angle is limited and cannot satisfy user demands

Engineering Contradiction:
Improvestabilization angle rangeVSAvoidmotor structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the image-stabilization function into two independent motors: a first motor for driving the lens and a second motor for driving the image sensor. This segmentation allows each motor to be optimized for specific movement directions, enabling broader stabilization angles without requiring a single complex motor structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces movement in multiple dimensions by adding the second motor that drives the image sensor in directions different from the first motor's lens movement. This multi-dimensional approach expands the stabilization angle range beyond what a single motor could achieve.

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

2Adaptability or versatility

If the lens is driven to move for image stabilization, then optical image-stabilization is achieved, but the image sensor position remains fixed limiting stabilization capability

Engineering Contradiction:
Improveimage stabilization capabilityVSAvoiddual motor system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the image-stabilization system into two functional modules: lens-driven stabilization (first motor) and sensor-driven stabilization (second motor). This segmentation enables independent optimization of each module's movement characteristics, achieving enhanced stabilization capability while maintaining manageable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dual motor system provides multi-functionality by enabling both lens movement and image sensor movement for stabilization. This universal approach allows the system to handle various stabilization scenarios and shooting conditions that a single motor system could not address.

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