Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional 3D projection systems limit audience immersion due to reliance on a single screen and require inconvenient polarized glasses, lacking integration of additional effects like sound, wind, and scent to enhance the 3D experience.

Innovation Solution

A multi-projection system with additional effect devices that synchronize and dynamically adjust sound, wind, smell, temperature, and other sensory effects across multiple projection surfaces, matching the direction and changes in the projected images to create a more immersive experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional single-screen projection is used, then the system is simple and easy to operate, but audience immersion and 3D effect are limited

Engineering Contradiction:

Improvesystem simplicityVSAvoidaudience immersion

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The single projection screen is segmented into multiple projection surfaces arranged in different spatial directions. Each surface can display images independently or in coordination, allowing the system to maintain operational simplicity while significantly enhancing audience immersion through multi-directional visual presentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a two-dimensional single screen to a three-dimensional multi-surface projection configuration. By arranging projection surfaces in various directions around the audience, the system creates a spatially distributed visual environment that dramatically improves immersion without complicating the core projection operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If polarized glasses are used for 3D effect, then 3D images can be provided, but audience convenience is reduced and some audiences feel dizzy or nausea

Engineering Contradiction:

Improve3D image provisionVSAvoidaudience convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of requiring audiences to wear polarized glasses to achieve 3D effect, the system inverts the approach by using multiple projection surfaces arranged in three-dimensional space to create the 3D effect directly. This eliminates the need for glasses and the associated discomfort while maintaining reliable 3D image provision.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The mechanical system of polarized glasses is replaced with an optical-spatial system using multiple projection surfaces. The 3D effect is achieved through the spatial arrangement and coordination of images across multiple surfaces rather than through polarized filtration, eliminating the need for physical glasses and reducing audience discomfort.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If additional effect devices are added to multi-projection system, then audience immersion is enhanced, but device complexity increases

Engineering Contradiction:

Improveaudience immersionVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The projection surfaces serve multiple functions: they display visual images and simultaneously act as sources for additional effects such as sound, wind, scent, and temperature. By integrating these functions into the existing multi-projection structure, the system enhances audience immersion without adding separate complex device systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The additional effect devices are merged with the projection surface system, where each projection surface is associated with its own additional effect device. This integration allows the system to provide enhanced immersion through coordinated visual and sensory effects while managing complexity through a unified control architecture.

Inventive Principle:

Principle #5Merging (Combining)

4Device complexity

If additional effects are provided without directionality, then the system is simple, but the 3D effect and immersion are not maximized

Engineering Contradiction:

Improvesystem simplicityVSAvoid3D effect

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Each projection surface is associated with additional effect devices that provide effects in directions specific to that surface's orientation and position. This local differentiation of effect directionality matches the spatial distribution of the projection surfaces, maximizing the 3D effect and immersion while maintaining manageable system complexity through modular implementation.

Inventive Principle:

Principle #3Local quality
