Solution Overview

Problem

Existing portable air caring apparatuses face issues with reduced air suction efficiency due to interference with structures when mounted, limited installation positions, decreased air flow rate, degraded air cleaning efficiency, increased air resistance, and inadequate control over air discharge direction.

Innovation Solution

A portable air caring apparatus with an inlet portion installed along the outer periphery of the first case portion, allowing air to suction evenly through a filter portion, minimizing sanitizing apparatus interference, and featuring a rotatable discharge portion for controlled air direction, while preventing finger contact with the fan module and reducing air resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the suction port is formed in one side surface of the lower portion of the body portion, then the structure is simple, but the air suction efficiency decreases when mounted on structures like cup holders

Engineering Contradiction:
Improvestructure simplicityVSAvoidair suction efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The suction port is divided into multiple segments: a first suction port in the lower portion and a second suction port in the upper portion of the front surface. This segmentation allows air to be drawn from multiple locations, maintaining suction efficiency even when mounted on structures like cup holders that may block the lower suction port.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the suction port is formed in one side of the body portion, then the device structure is simple, but the installation position is limited

Engineering Contradiction:
Improvedevice structureVSAvoidinstallation position flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The air caring apparatus is designed with multiple suction ports positioned at different heights (lower and upper front surfaces), making it universally adaptable to various mounting positions and orientations. This multi-functional suction configuration allows the device to be effectively installed in diverse locations such as cup holders, dashboards, or walls without compromising performance.

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

3Device complexity

If air moves mostly through one side of the filter close to the suction port, then the filter structure is simple, but the air cleaning efficiency is degraded

Engineering Contradiction:
Improvefilter structureVSAvoidair cleaning efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The filter is configured with air inlets at both the lower and upper portions, creating a multi-dimensional air flow pattern through the filter. This causes air to pass through different regions of the filter (front, rear, upper, lower portions), maximizing the utilization of the entire filter surface area and improving overall air cleaning efficiency.

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

4Reliability

If the sanitizing apparatus is disposed between the fan and the filter and installed across the inside of the body portion, then the sanitizing coverage is increased, but the air flow resistance is increased

Engineering Contradiction:
Improvesanitizing coverageVSAvoidair flow resistance
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The sanitizing apparatus is positioned specifically in the lower portion of the air flow path rather than across the entire interior. This localized placement provides adequate sanitizing coverage for the air passing through that region while minimizing interference with the overall air flow, thereby reducing air flow resistance and energy loss.

Inventive Principle:
Principle #3Local quality
