Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated control unit is designed for each specific ozone production range or client requirement, then the control precision and reliability are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvecontrol reliabilityVSAvoidcontrol unit complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control unit is designed with multi-functionality to handle different ozone production ranges and client requirements through a universal platform. The system uses a single control unit that can adapt to various machine types via identification codes and corresponding base setting files, eliminating the need for dedicated control units for each specific application.

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

Solution Approach 2:

The control unit adjusts its operation by changing parameters through loading different base setting files corresponding to specific ozone production ranges and client requirements. This allows the same hardware to function differently by modifying software parameters and coefficients rather than requiring different hardware designs.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If dedicated control units are manufactured for each specific machine type, then the adaptability to specific requirements is improved, but the ease of manufacture and maintainability deteriorate

Engineering Contradiction:
Improvemachine type adaptabilityVSAvoidcontrol unit manufacturing
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A universal control unit design serves multiple machine types through identification codes and configurable base setting files. This single platform approach improves ease of manufacture by standardizing the control unit hardware and software architecture, while maintaining adaptability through flexible configuration options.

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

Solution Approach 2:

Base setting files are prepared in advance for different ozone production ranges and client requirements. These pre-configured files contain optimal parameters and coefficients that are automatically loaded based on the machine's identification code, eliminating the need for manual configuration and reducing manufacturing complexity.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If sensors and actuators are used without correction, then the device complexity is reduced, but the manufacturing precision and ozone production consistency worsen due to sensor and actuator deviations

Engineering Contradiction:
Improvecontrol system complexityVSAvoidozone production precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The system implements feedback mechanisms where sensor readings and actuator performances are continuously monitored and compared against expected values. Correction coefficients are applied based on identified deviations, and the system adjusts control signals to compensate for sensor and actuator inaccuracies, maintaining precise ozone production control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Correction coefficients are introduced as adjustable parameters to compensate for sensor and actuator deviations. These coefficients are determined through calibration procedures and stored in base setting files, allowing the system to adjust its operation to maintain precision without requiring replacement of physical components.

Inventive Principle:
Principle #35Parameter changes
