Modular Chromakey Screen Assembly for Faster Reusable Setup

Solution Overview

Problem

Chromakey technology requires significant time, expense, and labor for setup, and generates industrial waste due to the use of large fabric and wood screens, making it challenging to install and dispose of.

Innovation Solution

A chromakey screen system comprising interconnected chromakey screen units with frames, screens, and fastening devices, allowing for a semi-permanent setup that can withstand adverse weather conditions and be easily adjusted in shape and size, using a grid pattern to form a single integrated screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large fabric screen with uniform single-color background is extensively stretched to differentiate subjects from background, then chromakey effect is achieved, but significant time, expense, and labor for setup is required

Engineering Contradiction:

Improvechromakey effectVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The screen is divided into multiple modular panels that can be independently assembled. Each panel contains a frame structure with tensioning mechanisms, allowing rapid assembly without extensive stretching and setup time while maintaining the required chromakey effect.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The screen system incorporates adjustable tensioning mechanisms and modular connections that allow dynamic assembly and configuration. This enables quick setup by simply connecting pre-prepared modular units rather than stretching and securing large fabric screens.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a large fabric screen with uniform single-color background is extensively stretched to differentiate subjects from background, then chromakey effect is achieved, but significant expense and labor are required

Engineering Contradiction:

Improvechromakey effectVSAvoidsetup labor

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The screen is divided into multiple modular panels that can be independently assembled. Each panel contains a frame structure with tensioning mechanisms, allowing rapid assembly without extensive stretching and setup time while maintaining the required chromakey effect.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular panels are pre-manufactured with uniform single-color backgrounds (typically green or blue) suitable for chromakey effects. This pre-preparation reduces on-site labor while maintaining the required chromakey effect.

Inventive Principle:

Principle #32Color changes

3Reliability

If a large fabric screen is used to cover wide area, then chromakey effect is achieved, but it is challenging to install the screen to fit the designed structure

Engineering Contradiction:

Improvechromakey effectVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The screen is divided into multiple modular panels that can be independently assembled. Each panel contains a frame structure with tensioning mechanisms, allowing rapid assembly without extensive stretching and setup time while maintaining the required chromakey effect.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular panel design with standardized connections allows the screen system to be configured in various shapes and sizes to fit different designed structures. The universal modular units can be arranged to create curved, angled, or flat configurations as needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If large quantities of screen fabric and wood are used, then chromakey effect is achieved, but environmental concerns arise regarding generation of industrial waste from disposing of materials

Engineering Contradiction:

Improvechromakey effectVSAvoidindustrial waste

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The modular screen system is designed for disassembly and reuse. After use, the modular panels can be easily taken apart, stored, and reused for future productions, significantly reducing the generation of industrial waste compared to disposable fabric and wood screens.

Inventive Principle:

Principle #34Discarding and recovering
