Solution Overview

Problem

Existing crowd guidance methods often result in the immediate overcrowding of the designated destination, failing to appropriately guide crowds to less crowded areas.

Innovation Solution

A guidance processing apparatus that acquires and analyzes images to determine crowd states, generating and controlling guidance information for display devices to distribute crowds evenly across different spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If crowd guidance is provided to a specific destination, then crowd guidance effectiveness is improved, but the destination becomes overcrowded immediately

Engineering Contradiction:
Improvecrowd guidance effectivenessVSAvoidcrowd density at destination
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system performs preliminary analysis of crowd distribution across multiple spaces before providing guidance. By acquiring images of multiple spaces and analyzing crowd states in advance, the system identifies suitable destinations that are not currently overcrowded, preventing the destination from becoming crowded immediately after guidance is provided.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors crowd states in multiple spaces and uses this feedback to dynamically adjust guidance recommendations. By comparing real-time crowd distribution data with guidance outcomes, the system adapts its guidance strategy to prevent destinations from becoming overcrowded, ensuring sustained guidance effectiveness.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If multiple target devices are controlled simultaneously, then crowd distribution balance is improved, but system complexity increases

Engineering Contradiction:
Improvecrowd distribution balanceVSAvoidsystem control complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The system divides the crowd management task into separate analysis and control components. The analysis unit processes images and crowd states independently for each space, while the control unit manages multiple target devices based on these analyzed results. This segmentation allows balanced crowd distribution without requiring complex integrated control of all devices simultaneously.

Inventive Principle:
Principle #1Segmentation
