Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional ventilation methods are used, then aerosols can be removed from bathrooms, but aerosol accumulation persists in high-use situations and harmful microbiology remains airborne for hours

Engineering Contradiction:

Improveaerosol removal efficiencyVSAvoidaerosol capture effectiveness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent replaces traditional mechanical ventilation systems with electrostatic collection panels that use electrostatic forces to capture aerosols. The collection panels create electrostatic fields that attract and capture charged aerosol particles, substituting mechanical air movement with electrostatic particle capture to achieve more reliable aerosol removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state and properties of aerosol collection by charging collection panels to high voltages (e.g., 10-50 kV) to create strong electrostatic fields. This parameter change enables the panels to actively attract and capture aerosol particles, transforming passive ventilation into active electrostatic collection.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If aerosols are allowed to accumulate, then ventilation requirements are reduced, but harmful bacteria and pathogens pose infection risks to humans

Engineering Contradiction:

Improveventilation system complexityVSAvoidhuman health risk from aerosols

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces electrostatic collection panels as intermediary devices between aerosol sources and the environment. These panels act as mediators that capture harmful aerosol particles before they can spread throughout the bathroom, reducing direct human exposure while maintaining a simpler overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent divides the bathroom space into multiple zones with strategically placed collection panels near aerosol generation sources (toilets, showers, sinks). This segmentation allows targeted aerosol capture in high-risk areas without requiring comprehensive ventilation of the entire space, reducing system complexity while maintaining health safety.

Inventive Principle:

Principle #1Segmentation

3Reliability

If electrostatic collection panels are added to bathrooms, then aerosol concentrations are reduced, but device complexity and installation requirements increase

Engineering Contradiction:

Improveaerosol capture effectivenessVSAvoidcollection system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs electrostatic collection panels that can serve multiple functions: aerosol capture, air ionization, and potential integration with existing electrical systems. This multi-functionality reduces overall system complexity by combining several beneficial effects into a single device rather than requiring separate systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The collection panels are designed to operate autonomously once installed, using high-voltage power supplies that require minimal maintenance. The electrostatic fields are self-regulating, and the panels continuously capture aerosols without requiring active control or monitoring, reducing operational complexity while maintaining high reliability.

Inventive Principle:

Principle #25Self-service
