Solution Overview

Problem

Users face difficulties in viewing electronic displays, such as hand-held devices, while in motion due to shaking, which disrupts their ability to focus on content.

Innovation Solution

An anti-shake mode is activated in the electronic display, which identifies user movement by processing captured images and transforms the displayed image to compensate for this movement, maintaining a stable viewing experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional gyroscopes or accelerometers are used to detect device movement, then movement detection can be achieved, but the transformation accuracy and stability compensation effectiveness are insufficient

Engineering Contradiction:

Improvemovement detection precisionVSAvoidimage stabilization reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent replaces traditional mechanical sensing systems (gyroscopes and accelerometers) with an optical-based image processing system. By capturing multiple images and analyzing user movement through image data, the system achieves more precise movement detection and more effective image stabilization without relying on mechanical sensors.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the electronic display is used while the user is moving, then the device can be used during activities like traveling, but the display shakes making it difficult for the user to focus on content

Engineering Contradiction:

Improveusage adaptability during motionVSAvoiddisplay stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system applies preliminary anti-action by detecting user movement in advance through image processing and then pre-compensating for the expected display instability. By transforming the displayed image based on detected movement patterns before they affect viewing, the system maintains display stability during user motion, enabling versatile usage during activities like traveling.

Inventive Principle:

Principle #9Preliminary anti-action

3Stability of the object's composition

If image transformation is applied to compensate for user movement, then viewing stability is improved, but processing complexity increases

Engineering Contradiction:

Improveviewing stabilityVSAvoidimage processing complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses copying by capturing multiple images of the user and creating a transformed copy of the displayed image that compensates for detected movement. Instead of directly manipulating the original display output, the system creates a corrected copy based on image analysis, achieving viewing stability while managing processing complexity through efficient image-based transformation.

Inventive Principle:

Principle #26Copying
