Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual or semi-automatic routing is used, then operator flexibility and equipment control are maintained, but routing complexity increases and error probability rises

Engineering Contradiction:
Improverouting operationVSAvoidrouting accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs self-routing by automatically determining optimal paths and controlling equipment without human intervention. The computer system autonomously plans transfer routes, selects equipment, and executes transfers based on real-time plant state feedback, eliminating manual routing operations while maintaining reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical routing operations with an automated computer-based control system. The mechanical decision-making process of operators is substituted with algorithmic path optimization and automated equipment control, reducing human error while maintaining operational flexibility.

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

2Productivity

If automated routing is implemented, then routing efficiency and accuracy improve, but system complexity increases

Engineering Contradiction:
Improvechemical transfer efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The computer system performs multiple functions including path optimization, equipment selection, transfer execution, and real-time monitoring within a single integrated platform. This multi-functional approach consolidates what would otherwise require separate complex subsystems, improving productivity while managing overall system complexity.

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

Solution Approach 2:

The system continuously monitors the actual plant state and uses this feedback to dynamically adjust routing decisions. Real-time feedback from sensors and equipment status allows the computer system to adapt to changing conditions, ensuring optimal performance without requiring overly complex predetermined control logic.

Inventive Principle:
Principle #23Feedback

3Productivity

If multiple simultaneous transfers are coordinated manually, then throughput can be increased, but operator workload and error risk increase

Engineering Contradiction:
Improvetransfer throughputVSAvoidtransfer coordination
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system autonomously coordinates multiple simultaneous transfers by independently planning and executing each transfer route while automatically resolving conflicts. The computer system manages the complexity of coordinating multiple transfers without requiring operator intervention, thereby increasing throughput while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The routing system dynamically adjusts transfer paths and timing based on real-time plant conditions and ongoing transfers. This dynamic coordination allows multiple transfers to proceed simultaneously with automatic conflict resolution, increasing throughput without overwhelming operators with coordination complexity.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If fixed routing paths are used, then system simplicity is maintained, but adaptability to deviations and optimization opportunities is reduced

Engineering Contradiction:
Improverouting system complexityVSAvoidrouting flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system employs dynamic routing that adapts to changing plant conditions, equipment availability, and ongoing transfers. Rather than following fixed predetermined paths, the computer system continuously calculates optimal routes based on current state feedback, providing routing flexibility while managing complexity through algorithmic optimization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The routing system changes operational parameters such as transfer paths, equipment selection, and transfer timing based on real-time plant conditions. This parameter adaptation allows the system to respond to deviations and optimize performance without requiring complex manual reconfiguration, balancing simplicity with flexibility.
