Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If disinfectants are used for air sterilization, then sterilization effect is improved, but human comfort deteriorates due to odor stimulation

Engineering Contradiction:
Improvesterilization effectVSAvoidodor stimulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical disinfectants with a plasma generator that uses electrical discharge to generate positive and negative ions for sterilization. This substitutes chemical action with physical plasma action, eliminating odor stimulation while maintaining sterilization effectiveness.

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

Solution Approach 2:

The patent changes the sterilization mechanism from chemical concentration to plasma ion concentration. By controlling electrical parameters (voltage, current, frequency) of the plasma generator, the system achieves sterilization without the harmful chemical byproducts that cause odor.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If ozone is used for air sterilization, then sterilization effect is improved, but human safety deteriorates requiring ventilation operations

Engineering Contradiction:
Improvesterilization effectVSAvoidhuman safety impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes ozone-based chemical sterilization with plasma ion sterilization. The plasma generator produces positive and negative ions that sterilize air without forming harmful ozone concentrations, eliminating the need for ventilation operations and improving human safety.

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

3Reliability

If ultraviolet sterilization is used, then sterilization function is provided, but human health deteriorates due to harmful effects

Engineering Contradiction:
Improvesterilization functionVSAvoidhuman health impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces ultraviolet radiation sterilization with plasma ion sterilization. Instead of using UV photons that can damage human DNA, the system uses charged ions from plasma discharge that sterilize through oxidation without the same health risks, improving human safety while maintaining sterilization function.

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

4Reliability

If single-function sterilization devices are used, then sterilization capability is provided, but device versatility deteriorates

Engineering Contradiction:
Improvesterilization capabilityVSAvoiddevice function
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent integrates multiple functions into a single device: the plasma generator provides sterilization, the light-emitting assembly provides illumination, and the housing with air inlet/outlet provides air circulation. This multi-functional design improves versatility while maintaining sterilization capability.

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

Solution Approach 2:

The patent combines sterilization and illumination functions into one integrated device. The plasma generator and light-emitting assembly share the same housing and power supply, merging two separate functions into a single versatile unit that reduces the need for multiple devices.

Inventive Principle:
Principle #5Merging (Combining)
