Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional HVAC systems use traditional air filtration and ventilation methods, then the system structure remains simple and cost-effective, but the air purification effectiveness is insufficient to prevent spread of airborne diseases

Engineering Contradiction:
Improveair purification effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines UV-C disinfection lamps with the existing HVAC air handling units, integrating pathogen elimination functionality into the conventional air filtration system. The UV-C lamps are positioned within the air flow path to disinfect air alongside the mechanical filtration process, creating a hybrid purification system that addresses both particulate and biological contaminants.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces sensor devices as intermediaries to monitor air quality parameters and UV-C lamp operation status. These sensors detect pathogens, particulate matter, and operational conditions, providing feedback to the control system to optimize purification effectiveness while maintaining system reliability without excessive complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If UV-C lamps are operated continuously to maximize pathogen elimination, then air disinfection effectiveness improves, but energy consumption and potential harmful radiation exposure increase

Engineering Contradiction:
Improveair disinfection effectivenessVSAvoidharmful UV-C radiation exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback control through sensor devices that continuously monitor air quality conditions and UV-C lamp performance. The control system adjusts UV-C lamp operation based on real-time sensor data, activating lamps when pathogen levels or air quality indicators warrant disinfection and deactivating them when conditions are safe, thereby optimizing effectiveness while minimizing harmful radiation exposure.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent makes the UV-C lamp operation dynamic rather than static, allowing the system to adjust lamp activation and intensity based on real-time air quality conditions, occupancy detection, and operational parameters. This dynamic control enables the system to provide maximum disinfection effectiveness when needed while reducing or eliminating UV-C exposure during periods when it is unnecessary or potentially harmful.

Inventive Principle:
Principle #15Dynamics

3Reliability

If real-time sensor monitoring and control systems are added to verify UV-C operation and air quality, then system reliability and verification capability improve, but device complexity and initial cost increase

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs sensor devices and control systems that perform multiple functions: monitoring air quality parameters, verifying UV-C lamp operation, detecting occupancy conditions, and providing feedback for optimization. This multi-functionality reduces the need for separate dedicated components for each monitoring task, thereby improving verification capability while limiting the increase in overall system complexity.

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