Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If driverless transport systems and robots are used to increase productivity, then work efficiency is improved, but safety risks to human participants increase

Engineering Contradiction:
Improvework efficiencyVSAvoidsafety risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces safety managers as intermediary entities that mediate between driverless transport systems/robots and human participants. These safety managers continuously monitor the environment, detect potential hazards, and coordinate safe interactions, thereby enabling high productivity while mitigating safety risks through an intermediate control layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements continuous feedback loops where safety managers receive real-time data from sensors about the positions and states of driverless transport systems and robots, process this information, and generate control signals to prevent unsafe operations. This closed-loop feedback mechanism ensures that productivity gains do not compromise human safety.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple driverless transport systems with different control subsystems are used, then system versatility is improved, but coordination complexity increases

Engineering Contradiction:
Improvesystem versatilityVSAvoidcoordination complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs universal safety managers that can interface with multiple different control subsystems through standardized communication protocols. These safety managers perform multiple functions including hazard detection, coordination, and safety monitoring across diverse driverless transport systems and robots, thereby managing coordination complexity while maintaining system versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes communication parameters and data formats to accommodate different control subsystems. By implementing adaptable parameter mappings and standardized interfaces, the safety managers can coordinate diverse systems without increasing operational complexity, allowing versatility to be maintained while complexity is managed through parameter standardization.

Inventive Principle:

3Productivity

If transport areas are made accessible without obstacles for people and machines, then operational efficiency is improved, but safety hazards increase

Engineering Contradiction:
Improveoperational efficiencyVSAvoidsafety hazards
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Safety managers act as intermediaries between free-access transport areas and human participants, continuously monitoring the environment and detecting potential hazards. This allows unobstructed access for improved operational efficiency while the safety managers provide real-time safety oversight and coordinate safe interactions, thereby mitigating safety hazards through intermediate monitoring and control.

Inventive Principle:
Principle #24Intermediary (Mediator)
