Solution Overview

Problem

Current three-dimensional imaging on mobile telephone and computer screens is limited as it requires the viewer to be at a specific distance and angle to maintain clarity, and does not adapt to changes in viewer position, leading to blurry images when the viewer moves.

Innovation Solution

Incorporating a sensor, such as a proximity sensor or camera, to gather distance data and adjust the three-dimensional image rendering accordingly, allowing for optimal viewing from any distance and enabling side or top views by shifting and re-rendering the images based on the viewer's location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed perspective images are superimposed on the screen for three-dimensional imaging, then the three-dimensional image can be viewed at a predetermined distance and angle, but the image becomes blurred or breaks down when the viewer moves outside this predetermined range

Engineering Contradiction:

Improveimage clarityVSAvoidviewing position flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the image perspective adjustable and adaptive rather than fixed. The system dynamically changes the perspective of the left and right images based on the detected viewer position, allowing the three-dimensional image to remain clear regardless of viewing distance or angle. This resolves the contradiction by enabling the system to adapt to different viewing conditions while maintaining image quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses feedback by detecting the viewer's position and using this information to adjust the image rendering. The system continuously monitors viewing conditions and modifies the perspective accordingly, creating a closed-loop system that maintains optimal image clarity. This feedback mechanism allows the system to compensate for viewer movement and prevent image degradation.

Inventive Principle:

Principle #23Feedback

2Reliability

If color filters are used to create three-dimensional images with different colors for each eye, then the system works well for black and white images, but the color filters affect the appearance of colors in colored images

Engineering Contradiction:

Improveimage clarityVSAvoidcolor accuracy

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent applies parameter changes by adjusting the perspective and positioning of images based on detected viewer position rather than using color filters. This alternative approach maintains color accuracy while achieving the three-dimensional effect, resolving the contradiction between image clarity and color fidelity.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If a sensor is added to detect viewer position and dynamically adjust image rendering, then the three-dimensional image remains clear at any viewing distance or position, but the device complexity increases

Engineering Contradiction:

Improveviewing position flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical adjustment systems with electronic sensing and software-based image rendering adjustments. Instead of physically moving components or using complex optical mechanisms, the system uses a sensor to detect viewer position and computationally adjusts the image perspective, significantly reducing mechanical complexity while maintaining adaptability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent adds the dimension of viewer position detection to the traditional fixed-perspective display system. By incorporating spatial awareness through sensing, the system transforms from a static two-dimensional display with fixed perspective to a dynamic system that adapts to three-dimensional viewer movement, enabling clear viewing from multiple positions without proportionally increasing complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
