Solution Overview

Problem

Dome screens in existing display technologies often result in discomfort for audiences seated far from the center due to high inclination, necessitating a larger radius and increased manufacturing costs to maintain viewer comfort.

Innovation Solution

A display screen with a cylindrical housing structure featuring a cross section that can be circular, elliptical, or quadrangular with rounded corners, allowing for a smooth transition and adjustable end portions, which provides a 180-360 degree view angle while reducing the volume and manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a dome screen is used to create immersion, then the sense of immersion is improved, but the viewing comfort for side-seated audiences deteriorates due to high inclination angles

Engineering Contradiction:
Improvesense of immersionVSAvoidviewing comfort
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies spherical geometry to create a dome screen that encloses audiences, providing immersive 360-degree viewing. The curved surface allows audiences to view images from multiple angles while maintaining comfortable viewing distances, resolving the contradiction between immersion and comfort through geometric design.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of operation

If the dome screen radius is increased to improve side-seated audience comfort, then viewing comfort is improved, but the manufacturing cost increases

Engineering Contradiction:
Improveviewing comfortVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent implements a partially-dome screen design that provides sufficient immersion and comfortable viewing angles without requiring a full 360-degree dome structure. This partial implementation reduces manufacturing complexity and cost while maintaining the essential benefits of dome screening for side-seated audiences.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of manufacture

If a seamless rear projection dome display system is implemented, then the sense of immersion is improved, but the construction complexity and cost increase

Engineering Contradiction:
Improvesense of immersionVSAvoidconstruction complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent divides the dome screen into multiple spliced segments rather than requiring a single seamless structure. This segmentation simplifies construction by allowing modular assembly of smaller screen sections, reducing the overall complexity while maintaining the immersive dome experience.

Inventive Principle:
Principle #1Segmentation
