Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time monitoring and recognition of human-machine collaboration state is implemented, then collaboration efficiency and safety are improved, but system complexity and data processing requirements increase

Engineering Contradiction:
Improvecollaboration safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the collaboration state recognition into multiple independent modules: ergonomic data acquisition module, operation scene image acquisition module, collaboration state recognition module, and personnel state recognition module. Each module handles specific aspects of monitoring, reducing overall system complexity while maintaining comprehensive safety monitoring.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a state recognition system as an intermediary that processes ergonomic data and operation scene images to generate collaboration state information. This intermediary layer simplifies the interaction between raw sensors and control systems, making the overall system more manageable despite the increased monitoring capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple data sources (ergonomic data and operation scene images) are integrated for state recognition, then recognition accuracy is improved, but data processing time and computational load increase

Engineering Contradiction:
Improvestate recognition accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary processing of ergonomic data and operation scene images before integration, including feature extraction and preliminary classification. This preliminary action reduces the complexity of subsequent integration processing, maintaining high recognition accuracy while reducing overall processing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements selective processing where only relevant features from ergonomic data and operation scene images are processed in detail, while less critical data receives simplified processing. This partial action approach maintains sufficient recognition accuracy while significantly reducing computational load and processing time.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If continuous monitoring of operation subject state is performed, then real-time feedback capability is improved, but energy consumption and system resource usage increase

Engineering Contradiction:
Improvereal-time feedback capabilityVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring with variable intervals, where the monitoring frequency is adjusted based on the current collaboration state and task requirements. During stable states, monitoring occurs at lower frequency to reduce energy consumption, while during critical transitions or high-risk operations, monitoring frequency increases to maintain real-time feedback capability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The monitoring system dynamically adjusts its operation based on detected state changes and task priorities. When the operation subject enters a new task phase or when anomalies are detected, the system intensifies monitoring temporarily, then returns to normal periodic monitoring, optimizing energy consumption while maintaining productivity.

Inventive Principle:
Principle #15Dynamics

AI summary

Provided are a method and an apparatus for feedbacking a human-machine collaboration state based on virtual-real integration, and an electronic device. Ergonomic data of an operation subject in a human-machine collaboration process for a current operation task and an operation scene image that is obtained by shooting the human-machine collaboration process and at least includes an operation device and a setting parameter of an operation environment are acquired. A human-machine collaboration state recognition is performed based on the operation scene image to obtain target collaboration state data corresponding to the current operation task, and a personnel state recognition is performed based on the ergonomic data to obtain personnel state data of the operation subject. Based on the target collaboration state data and the personnel state data, a state of the human-machine collaboration process is feedbacked.
