Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single ion generator is used, then the device complexity is low, but the ion concentration in the room is insufficient for effective virus elimination and odor removal

Engineering Contradiction:
Improveion concentrationVSAvoiddevice complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The air blower is divided into two separate air-flowing paths, each with its own ion generating section. This segmentation allows multiple ion generators to operate independently without interfering with each other, thereby increasing the total ion concentration in the room while maintaining manageable device complexity through modular design

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple ion generators are arranged in a single air-flowing path, then the ion concentration increases, but the ions interfere with each other and the sterilization effect is reduced

Engineering Contradiction:
Improveion concentrationVSAvoidsterilization effect
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The air-flowing path is segmented into two separate paths, with each path containing one ion generating section. This prevents ion interference between generators while still achieving high ion concentration in the room, thereby maintaining reliable sterilization and odor elimination effects

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of arranging multiple ion generators along a single linear path, the invention uses two separate air-flowing paths that diverge from the air blower. This spatial arrangement in another dimension allows independent ion generation without interference, solving the contradiction between ion concentration and sterilization effectiveness

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If a standard ion sensor is used, then the device complexity is low, but the detection accuracy decreases due to insulation degradation and humidity

Engineering Contradiction:
Improveion detection accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The collecting electrode is preliminarily protected by enclosing it within a protective electrode before exposure to the environment. This preliminary protective action prevents insulation degradation and humidity interference, maintaining high ion detection accuracy while adding only moderate device complexity through the enclosing structure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The protective electrode serves as a beforehand cushioning barrier that protects the collecting electrode from harmful environmental factors such as humidity and contamination. This prior protection ensures sustained detection accuracy without requiring complex environmental control systems

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An air blower including a motor 2 having output shafts 21, 21 on both sides in the axial direction and two impellers 3, 3 mounted on the respective output shafts 21, 21, and two ducts 5, 5 that individually allow passage of the air blown out by rotation of each of the impellers 3, 3 in the same direction and discharge the air to the outside are included. At a part or the whole of each of the ducts 5, 5, a laminar flow section that makes the flowing air laminar flow. An ion generating section is arranged at each laminar flow section so that ions generated by the ion generating section can effectively be included in the air, increasing the ion concentration of ions discharged in a room together with the air.
