Solution Overview

Problem

Existing systems for controlling indoor air quality (IAQ) lack an integrated solution for efficiently conveying and cleaning air, particularly in HVAC systems, which can lead to inadequate removal of airborne pollutants and pathogens.

Innovation Solution

A fluid moving system that includes a fluid moving apparatus integrated with an IAQ sensor and an active cleaning device, such as a UV light source or ion generator, which conveys air through a housing and removes undesired matter using an electric motor and motor controller.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional air processing systems are added to mitigate airborne pollutants, then indoor air quality is improved, but device complexity increases

Engineering Contradiction:
Improveairborne pollutantsVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the fluid moving apparatus (fan/blower) with an active cleaning device (UV-C light source) into a single integrated unit. The cleaning device is positioned within the housing to treat air as it passes through, eliminating the need for separate air processing systems while maintaining air quality improvement functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated apparatus performs multiple functions: the fluid moving apparatus conveys air through the housing while the active cleaning device simultaneously neutralizes pathogens and pollutants. This multi-functional design replaces what would traditionally require separate ventilation and air purification systems.

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

2Object-affected harmful factors

If air is conveyed through a housing with active cleaning devices, then removal of undesired matter is improved, but use of energy increases

Engineering Contradiction:
Improveundesired matterVSAvoidenergy consumption
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The active cleaning device operates continuously as air passes through the housing, ensuring constant neutralization of pathogens and pollutants without requiring intermittent cycling. The fluid moving apparatus maintains continuous airflow, allowing the cleaning device to work constantly on the passing air stream.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The housing acts as an intermediary chamber that channels air through the active cleaning device. This design allows the cleaning device to treat air efficiently in a controlled environment without requiring high energy input, as the airflow is directed through a confined space where the cleaning action is maximized.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If an electric motor with motor controller is used to turn the fluid moving apparatus, then speed control is improved, but device complexity increases

Engineering Contradiction:
Improvefluid movement speedVSAvoidmotor control system
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The electric motor with motor controller enables dynamic speed adjustment of the fluid moving apparatus. The motor controller receives signals from sensors (such as CO2 sensors) and adjusts the motor speed accordingly, allowing the system to adapt airflow rates to real-time air quality conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors that monitor air quality parameters and provide feedback to the motor controller. Based on this feedback, the controller adjusts the motor speed to maintain optimal airflow for the current air quality conditions, creating a closed-loop control system.

Inventive Principle:
Principle #23Feedback
