Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional deodorization equipment is used, then odor removal function is provided, but initial installation cost and operation cost are high

Engineering Contradiction:
Improveodor removal functionVSAvoidinitial installation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The deodorization system is divided into multiple independent modules: UV irradiation module, plasma module, ozone generation module, and catalytic decomposition module. Each module can be independently designed, manufactured, and maintained, reducing overall system cost while maintaining effective odor removal functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs replaceable consumable components such as UV lamps and catalyst sheets that can be easily replaced when depleted. This approach reduces long-term operational costs by allowing economical replacement rather than expensive system overhaul, addressing the high operation cost issue.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If conventional deodorization equipment is used, then odor removal function is provided, but repair and maintenance cost are high

Engineering Contradiction:
Improveodor removal functionVSAvoidrepair and maintenance cost
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

By segmenting the system into modular components (UV module, plasma module, ozone module), maintenance can be performed on individual modules rather than the entire system. This reduces maintenance complexity and cost, as only the affected module needs to be serviced or replaced.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system includes self-diagnostic and self-maintenance features such as automatic monitoring of component status and easy-access replacement designs for consumables like UV lamps and catalyst sheets, enabling minimal intervention maintenance and reducing professional repair costs.

Inventive Principle:
Principle #25Self-service

3Reliability

If existing deodorization technology is applied, then odor treatment is achieved, but energy consumption is high

Engineering Contradiction:
Improveodor treatment effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple deodorization mechanisms (UV irradiation, plasma generation, ozone production, catalytic decomposition) into a single integrated system that works synergistically. This multi-modal approach achieves superior odor removal efficiency while optimizing overall energy consumption by distributing the treatment load across different mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically adjusts operational parameters such as UV lamp power, plasma generation intensity, and ozone flow rate based on real-time odor concentration monitoring. This adaptive parameter control ensures effective odor treatment while minimizing energy consumption by operating at optimal rather than maximum levels.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If multifunctional microwave plasma and ultraviolet treatment is used, then purifying capacity and efficiency are improved, but device complexity increases

Engineering Contradiction:
Improvepurifying capacityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The complex multifunctional system is divided into distinct functional modules (UV irradiation, microwave plasma, ozone generation, catalytic decomposition), each housed in separate chambers. This modular segmentation manages device complexity by making each component independent and manageable while achieving high purifying capacity through their combined effect.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent integrates multiple deodorization functions into a single unified system that can handle various types of odors and exhaust gases. The multi-functional design achieves high purifying capacity by addressing different odor mechanisms simultaneously, while the modular architecture keeps complexity manageable through standardized interfaces and control systems.

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