Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual measurement by counter is used, then measurement accuracy is improved, but time delay in reflecting data to simulator increases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidtime delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical counting with automated detection systems (cameras, sensors, RFID readers) that automatically detect and count people passage. This substitution eliminates manual intervention delays while maintaining measurement accuracy, as the automated systems continuously monitor and immediately transmit data to the simulator without human processing time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary data transmission system (network communication module, server) that bridges the measurement device and simulator. This intermediary automatically relays measurement data to the simulator in real-time, eliminating the manual reflection process and enabling immediate updates in the simulation environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If real-time measurement and simulation update is implemented, then simulation timeliness is improved, but system complexity increases

Engineering Contradiction:

Improvesimulation speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the system into separate functional modules: detection module (camera/sensor), measurement module (counter), transmission module (communication unit), and simulation module (simulator). This segmentation allows each component to perform its specific function independently, making the overall complex real-time system manageable and easier to implement through modular architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements self-service automation where the measurement device automatically detects, counts, and transmits data without human intervention. The simulator automatically receives and processes this data to update simulation parameters in real-time. This self-service mechanism reduces the need for complex manual coordination while enabling timely simulation updates.

Inventive Principle:

Principle #25Self-service

AI summary

The present invention can perform a human flow simulation in real time. An input unit (102) receives an input of passage information indicating passage through a point, a measurement unit (103) measures the number of passing people through the point by adding the received passage information, and a transmission unit (104) transmits the number of passing people measured by the measurement unit (103) at a predetermined time interval to a server that generates a parameter of a human flow simulation.
