Solution Overview

Problem

Current 3D display technologies on user terminals cannot adapt flexibly to different viewing locations or angles, resulting in a suboptimal 3D experience for users.

Innovation Solution

A method and user terminal that dynamically adjust the 3D projection angle based on the user's viewing angle, detected through the medial-axis angle of view or left/right-eye angles, allowing for real-time adjustment of the 3D display to maintain a vivid and clear image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If 3D display is performed at a fixed angle of 3D projection, then the device complexity is reduced and ease of operation is improved, but the adaptability to different viewing locations or angles deteriorates

Engineering Contradiction:
Improveadaptability to different viewing locations or anglesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the 3D projection angle adjustable and adaptive rather than fixed. The system dynamically changes the projection angle based on detected user viewing angles, allowing the display to adapt to different viewing positions while maintaining optimal 3D effects. This resolves the contradiction by introducing dynamic adjustment capability without requiring complex hardware changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by detecting the user's viewing angle and using this information to adjust the 3D projection angle accordingly. The system continuously monitors user position and adjusts the projection parameters in real-time, creating a closed-loop control system that enhances adaptability while keeping the device complexity manageable through software-based adjustments.

Inventive Principle:
Principle #23Feedback

2Reliability

If 3D display is performed at a fixed angle of 3D projection, then the device complexity is reduced, but the 3D display effect deteriorates when user viewing angle changes

Engineering Contradiction:
Improve3D display effect qualityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by adjusting the 3D projection angle parameter based on detected user viewing angles. Instead of changing hardware configuration, the system modifies display parameters (projection angle) dynamically to maintain optimal 3D display quality across different viewing positions, resolving the contradiction between reliability and device complexity.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If 3D display is performed at a fixed angle of 3D projection, then the ease of operation is improved, but the user experience deteriorates for users at different viewing positions

Engineering Contradiction:
Improveease of operationVSAvoidadaptability to different viewing locations or angles
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements self-service by enabling the system to automatically detect user viewing angles and adjust the 3D projection parameters without requiring manual user intervention. The device serves itself by adapting to user position automatically, maintaining ease of operation while significantly improving adaptability to different viewing locations.

Inventive Principle:
Principle #25Self-service
