Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual processing is used to identify dance segments in online class videos, then accuracy can be maintained through human judgment, but the process becomes time-consuming and labor-intensive

Engineering Contradiction:
Improveaccuracy of dance segment identificationVSAvoidtime required for manual processing
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical review with an automated computer-based system that uses audio analysis to detect music segments and video analysis to detect dance moves, automatically identifying dance segments without human intervention while maintaining accuracy through algorithmic detection

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

Solution Approach 2:

The system enables self-service by allowing the computer to autonomously process videos, extract audio and video segments, analyze them independently, and automatically determine dance segments based on predefined criteria without requiring manual verification or intervention

Inventive Principle:
Principle #25Self-service

2Reliability

If manual processing is used to identify dance segments in large volumes of videos, then quality control can be maintained, but productivity becomes extremely low

Engineering Contradiction:
Improvequality control of dance segment identificationVSAvoidspeed of processing video segments
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent divides the video processing task into independent audio segment extraction and video segment analysis components, allowing parallel processing of multiple video files simultaneously, which dramatically increases productivity while maintaining quality through consistent algorithmic application

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses objectively measurable parameters such as audio frequency patterns for music detection and skeletal motion parameters for dance move detection, replacing subjective human judgment with quantifiable metrics that ensure consistent quality across large volumes of processed videos

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated methods are introduced to increase processing speed, then productivity improves, but accuracy and reliability may deteriorate due to algorithmic errors

Engineering Contradiction:
Improvespeed of dance segment recognitionVSAvoidaccuracy of dance segment identification
Core Design Contradiction:

AI summary

A dance segment recognition method includes: extracting an audio segment from a video segment in response to the audio segment including a music segment with a time length greater than or equal to a pre-specified time length, using a video sub-segment that is included in the video segment and that corresponds to the music segment as a candidate dance segment and in response to a quantity of image frames showing a dance move in a plurality of image frames of the candidate dance segment being greater than a first pre-specified threshold, determining the candidate dance segment to be a dance segment. The dance segment recognition method can increase the speed of recognizing a dance segment in a video segment.
