Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If real-time monitoring and feedback systems are implemented, then task execution accuracy and efficiency are improved, but system complexity and cost increase

Engineering Contradiction:
Improvetask execution efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a feedback system that captures video data of material handling tasks, analyzes the actions performed, and provides real-time feedback to workers. The system monitors task execution, compares it against correct procedures, and delivers corrective feedback, thereby improving task execution accuracy and efficiency without requiring complex manual monitoring systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual monitoring and supervision with an automated video-based analysis system. Instead of using human supervisors to observe and correct worker actions, the system uses video capture devices, image processing algorithms, and automated analysis to monitor and provide feedback, reducing the need for human intervention while improving consistency and coverage.

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

2Reliability

If manual monitoring of material handling tasks is performed, then task accuracy can be maintained, but time consumption and labor costs increase

Engineering Contradiction:
Improvetask execution accuracyVSAvoidmonitoring time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent enables the system to autonomously perform monitoring, analysis, and feedback delivery without requiring continuous human intervention. The automated system captures video data, analyzes worker actions, identifies deviations from correct procedures, and provides feedback independently, eliminating the need for manual monitoring while maintaining high task execution accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent substitutes manual monitoring with an automated video analysis system that uses image processing and pattern recognition algorithms to detect and analyze material handling actions. This automated approach maintains reliability by consistently applying analysis criteria while eliminating the time consumption and labor requirements of manual monitoring.

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

3Reliability

If detailed task analysis and feedback are provided to workers, then error reduction is achieved, but information processing requirements increase

Engineering Contradiction:
Improveerror reductionVSAvoidinformation processing load
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts only the critical and relevant information from video data for analysis and feedback delivery. Instead of processing all video information, the system identifies key actions, deviations, and corrective needs, extracting only the essential data required for error reduction. This selective extraction reduces information processing load while maintaining effectiveness in reducing task errors.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent provides targeted feedback focused on specific actions or deviations rather than comprehensive analysis of all task aspects. The system identifies localized errors or deviations in material handling actions and provides corrective feedback specifically for those areas, reducing the overall information processing requirements while effectively reducing errors in critical areas.

Inventive Principle:
Principle #3Local quality

AI summary

Various examples are directed to systems and methods for utilizing depth videos to analyze material handling tasks. A material handling facility may comprise a depth video system and a control system programmed to receive a plurality of depth videos including performances of the material handling task. For each of the plurality of depth videos, training data may identify sub-tasks of the material handling task and corresponding portions of the video including the sub-tasks. The plurality of depth videos and the training data may be used to train a model to identify the sub-tasks from depth videos. The control system may apply the model to a captured depth video of a human agent performing the material handling task at a workstation to identify a first sub-task of the material handling task being performed by the human agent.
