Solution Overview

Problem

Conventional large screen displays require manual and time-consuming configuration of slave displays, which is impractical and inefficient, especially for arrangements larger than 3x3 displays, due to the lack of effective automatic configuration methods.

Innovation Solution

A master display system that automatically identifies and configures the positions of slave displays using contact data exchange between displays, enabling automatic setup and positioning even in irregular arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual programming is used to configure slave display locations, then the configuration can be done with simple devices, but the time consumption and complexity increase significantly

Engineering Contradiction:
Improveautomatic configurationVSAvoidconfiguration system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The slave displays automatically identify their own positions by exchanging contact data with adjacent displays. Each slave display determines its location based on contact signals from neighbors without requiring manual programming or complex control systems, enabling self-configuration of the entire display wall.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical configuration (physically programming each display location) with an automatic sensing system using contact data exchange. The contact identification components detect physical contact between adjacent displays to automatically determine spatial relationships and positions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual programming is used for slave display locations, then the system remains simple, but productivity and setup speed decrease

Engineering Contradiction:
Improveconfiguration speedVSAvoidsetup time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The contact identification components are pre-installed on the displays, and the automatic position identification system is built into the display units. When displays are physically arranged, the contact data exchange automatically occurs, instantly configuring the system without requiring time-consuming manual programming steps.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If automatic configuration methods are used, then setup time is reduced, but these methods are limited to small arrangements (at most 3x3)

Engineering Contradiction:
Improvedisplay arrangement flexibilityVSAvoidnumber of displays
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The display wall is divided into individual slave displays, each equipped with contact identification components that independently identify their positions. This segmentation allows the system to scale to any size configuration, as each display unit autonomously determines its location through contact data exchange with adjacent units, eliminating the 3x3 limitation of previous automatic configuration methods.

Inventive Principle:
Principle #1Segmentation
