Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wet mechanism is adopted for virus removal, then virus removal probability is improved, but pressure loss increases and device size increases

Engineering Contradiction:
Improvevirus removal probabilityVSAvoidpressure loss
Core Design Contradiction:
ReliabilityVSStress or pressure

Solution Approach 1:

The patent employs a rotary brush catcher that rotates to collect viruses from the gas stream. The rotation creates dynamic airflow patterns that reduce pressure loss while maintaining effective virus collection. The movable brush structure allows gas to flow through with less resistance compared to static wet filters.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses a liquid spraying mechanism that introduces liquid into the treatment room to enhance virus removal. The liquid is sprayed in a controlled manner to achieve effective virus capture without creating excessive pressure loss, balancing wet mechanism effectiveness with airflow efficiency.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If a wet mechanism is adopted for virus removal, then virus removal probability is improved, but device size increases with respect to amount of air to be treated

Engineering Contradiction:
Improvevirus removal probabilityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The rotary brush catcher uses rotational motion to enhance virus collection efficiency within a compact volume. The rotation creates multiple collection zones and improves gas-liquid contact efficiency, allowing effective virus removal in a smaller device footprint compared to conventional wet filters.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters by using a rotating brush mechanism with controlled liquid spraying. This dynamic parameter control allows efficient virus removal in a compact device, reducing the volume required per unit of air treated compared to static wet filtration systems.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If liquid spraying is used to kill viruses, then virus removal efficiency is improved, but liquid consumption increases

Engineering Contradiction:
Improvevirus removal efficiencyVSAvoidliquid consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent implements a continuous liquid spraying mechanism that maintains constant virus-killing action throughout the treatment room. The continuous spray ensures high virus removal efficiency while optimizing liquid distribution to minimize consumption, avoiding both under-spraying (inefficient removal) and over-spraying (excessive consumption).

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The rotary brush catcher collects viruses and brings them into contact with the sprayed liquid, creating a self-enhancing system where the brush motion concentrates viruses into the liquid path, improving kill efficiency without proportionally increasing liquid consumption.

Inventive Principle:
Principle #25Self-service
