Solution Overview

Problem

Existing image display apparatuses face challenges in providing an optimal stereoscopic view display due to large size, difficulty in adjusting inclination for subtle user posture changes, and loss of stereoscopic effect when body parts obstruct the view.

Innovation Solution

An image display apparatus with a display unit, image processing unit, and display controlling unit that adjusts the depth range and inclination based on detected user input and posture, using sensors to optimize the stereoscopic view display without the need for complex adjustment mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanism for automatically adjusting the inclination of image display apparatus is provided, then the stereoscopic view display can be observed in an optimum state, but the image display apparatus becomes large in size

Engineering Contradiction:

Improvestereoscopic view display qualityVSAvoidapparatus size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent replaces the mechanical inclination adjustment mechanism with an image processing approach. The image processing unit adjusts the depth range and stereoscopic parameters through software processing rather than physically tilting the display apparatus, thereby maintaining optimal stereoscopic viewing without increasing apparatus size.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the depth range parameter of the stereoscopic image dynamically. By adjusting the depth range according to user posture and interaction, the system maintains optimal stereoscopic display quality without requiring physical inclination adjustment mechanisms.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a mechanism for automatically adjusting the inclination of image display apparatus is provided, then the stereoscopic view display can be observed in an optimum state, but it is difficult to adjust the inclination in accordance with subtle changes of user posture

Engineering Contradiction:

Improvestereoscopic view display qualityVSAvoidadjustment responsiveness

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the system continuously detects user interactions and posture changes, then dynamically adjusts the depth range and stereoscopic parameters in real-time. This allows the system to respond to subtle changes in user posture without requiring complex mechanical adjustment mechanisms.

Inventive Principle:

Principle #23Feedback

3Reliability

If the depth range in the stereoscopic view display is increased, then the stereoscopic effect is enhanced, but body parts such as hands and fingers may obstruct the perceptive aspect and lose the stereoscopic effect

Engineering Contradiction:

Improvestereoscopic effectVSAvoidbody part obstruction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent dynamically adjusts the depth range based on detected user interactions. When body parts are detected near the display, the system reduces the depth range to prevent obstruction of the perceptive aspect, thereby maintaining the stereoscopic effect. This dynamic adjustment allows the system to adapt to changing viewing conditions in real-time.

Inventive Principle:

Principle #15Dynamics
