Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation of water wash system is used, then flexibility in operation is maintained, but complexity of operation and time consumption increase significantly

Engineering Contradiction:
Improveease of operationVSAvoidshutdown time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs the wash cycle automatically without requiring continuous manual intervention. The controller autonomously manages valve operations, pump control, and cycle sequencing, allowing the system to serve itself during the wash process while minimizing human involvement and shutdown time.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical operations are replaced with an automated control system that uses sensors, controllers, and automated valves to manage the wash process. This substitution of manual mechanical control with an automated control system reduces operational complexity and time consumption.

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

2Reliability

If multiple operators are deployed for manual wash, then monitoring capability is enhanced, but system complexity and operational cost increase

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system incorporates sensors that continuously monitor wash parameters and provide feedback to the controller. This feedback mechanism ensures consistent wash quality by automatically adjusting operations based on real-time conditions, replacing the need for multiple operators to visually monitor and manually adjust parameters.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Human operators are replaced with an automated control system that uses electronic sensors and controllers to monitor and manage the wash process. This substitution maintains or improves monitoring capability while reducing system complexity and operational requirements.

Inventive Principle:

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated control system is designed to perform multiple functions including cycle sequencing, parameter monitoring, valve control, and anomaly detection within a single integrated controller. This multi-functionality reduces the need for separate specialized components, thereby managing system complexity while maintaining high productivity.

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

Solution Approach 2:

The system uses programmable parameters and settings that can be adjusted to optimize different wash scenarios without requiring hardware changes. This flexibility allows the system to adapt to various conditions through software configuration rather than physical modifications, managing complexity while improving productivity.
