Solution Overview

Problem

Flat-panel displays struggle to recreate the realistic interaction between directional light sources and space, leading to reduced immersion due to their inability to simulate light-shadow variations beyond the screen area.

Innovation Solution

A scenario projection system comprising a display device, a reflective device, and a scenario light source positioned on a slide rail, where the scenario light source projects a directional beam that is reflected by the reflective device to extend light-shadow interactions beyond the screen area, enhancing the realism of virtual scenery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a flat-panel display is used to display images, then image quality is improved, but the sense of reality is reduced due to inability to simulate directional light-shadow interaction

Engineering Contradiction:
Improveimage qualityVSAvoidsense of reality
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

A reflective device is introduced as an intermediary between the display device and the projection device. The reflective device reflects the projection light to form a characteristic image that links with the displayed image, enabling directional light-shadow interaction in the virtual scene without compromising the original image quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent combines the display device and projection device into an integrated scenario projection system. The display device provides the base image while the projection device adds directional lighting effects, and both work together through the reflective device to create a unified virtual scene with enhanced realism.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a reflective device and projection device are added to simulate directional light sources, then the sense of reality is improved, but the device complexity increases

Engineering Contradiction:
Improvesense of realityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The reflective device serves multiple functions: it reflects the projection light to create directional lighting effects, forms the characteristic image that links with the displayed image, and integrates the functionality of both display and projection into a single system component, thereby reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the scenario light source projects beam to the screen area, then light-shadow interaction beyond screen area is achieved, but the area of illumination is limited to screen region

Engineering Contradiction:
Improvelight-shadow interactionVSAvoidillumination area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The reflective device redirects the projection light from the screen area into the three-dimensional space surrounding the display. This transforms the illumination from a two-dimensional screen-based projection to a three-dimensional spatial lighting effect, allowing light-shadow interactions to occur beyond the screen boundaries.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A scenario projection system and a controlling method thereof are provided. The scenario projection system includes a display device, a reflective device and a scenario light source. The display device is configured to show an image on the screen area of the display device. The scenario light source disposed on a slide rail is to project a scenario beam to the screen area where the reflective device is disposed within. The reflected scenario beam by the reflective device is to form a characteristic image outside the screen area, wherein there is a linkage relationship between the image and the characteristic image.
