Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual designation of detection region using mouse or coordinate input is used, then detection region can be set, but operation becomes complex and time-consuming

Engineering Contradiction:

Improveease of setting detection regionVSAvoidtime for setting detection region

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically identifies and sets the detection region by analyzing the captured image itself, without requiring external manual input. The processor detects edges, contours, or specific features in the image to autonomously determine the detection region boundaries, making the system self-configuring and eliminating manual operation steps

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of the captured image to pre-identify potential detection regions before actual object detection begins. By pre-processing the image to highlight regions of interest, the system prepares the detection framework in advance, reducing the time needed during actual operation

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If manual coordinate input is used to set detection region, then detection region can be defined, but device complexity increases

Engineering Contradiction:

Improveease of setting detection regionVSAvoidcomplexity of detection region setting

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical operations (mouse clicking, coordinate typing) with automated image processing algorithms. The processor uses computational methods to analyze pixel data, identify patterns, and automatically define detection regions, substituting human manual control with automated digital processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Provided is a moving object detection device and the like which can easily set a detection region for performing detection of a moving object and perform the detection of the moving object. A moving object detection device 10 includes a specifying unit 11 that acquires an image captured by a camera 1 and specifies a predetermined region satisfying a predetermined condition in the image, a setting unit 12 that sets the predetermined region specified by the specifying unit 11 or a region other than the predetermined region specified by the specifying unit 11 in the image as a detection region for performing detection of a moving object, and a detection unit 13 that performs the detection of the moving object in the detection region.
