Solution Overview

Problem

Conventional image presentation methods, including static pictures and dynamic videos, fail to effectively provide a comprehensive view of a scene, and existing three-dimensional display technologies like light-splitting stereoscopic displays are not suitable for long-term viewing due to high mental load and limited viewing angles.

Innovation Solution

An image display system that projects images of a target object from multiple angles onto a common display region using projection and refraction units, allowing for multi-angle presentation without the need for extra display components, and adapts to human eye viewing habits by refracting and collecting rays to create a seamless 360-degree image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If light-splitting stereoscopic display is used to achieve three-dimensional image presentation, then three-dimensional effect is improved, but mental load increases and viewing comfort deteriorates

Engineering Contradiction:

Improvethree-dimensional image presentationVSAvoidmental load

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Instead of splitting light into separate images for each eye (light-splitting method), this patent inverts the approach by projecting multiple angle images onto a common display region and using refraction to guide viewing. This inversion eliminates the need for artificial parallax construction, reducing mental load while maintaining three-dimensional presentation capability

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the parameter of image construction from manually produced parallax to naturally captured multi-angle images. By using images photographed from N different angles and refracting them to a common region, the system adapts to human eye viewing habits, reducing the cognitive burden on viewers

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If light-splitting stereoscopic display is used to achieve three-dimensional image presentation, then three-dimensional effect is improved, but viewing duration decreases due to unsuitability for long-time viewing

Engineering Contradiction:

Improvethree-dimensional image presentationVSAvoidviewing duration

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The patent inverts the conventional light-splitting approach by using a common display region with refraction-based viewing guidance. This allows viewers to observe multi-angle images naturally without the discomfort of stereoscopic separation, enabling longer viewing durations

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system allows viewers to freely observe images from different angles within the common display region without requiring special glasses or devices. The refraction units guide light naturally, enabling self-service viewing that is comfortable for extended periods

Inventive Principle:

Principle #25Self-service

3Ease of operation

If conventional presentation means are used to provide comprehensive scene understanding, then viewing comfort is maintained, but angle of view remains limited

Engineering Contradiction:

Improveviewing comfortVSAvoidangle of view

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent merges N images from different angles into a single common display region. By combining multiple perspective images and using refraction to present them together, the system expands the angle of view while maintaining natural viewing comfort

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from single-angle two-dimensional presentation to multi-angle three-dimensional presentation by projecting images from N different angles onto a common region. This dimensional enhancement provides comprehensive scene understanding while maintaining viewing comfort

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
