Solution Overview

Problem

Conventional tower fan designs are unable to manipulate airflow patterns, limiting their ability to create desired airflow configurations.

Innovation Solution

The integration of adjustable, pivotally mounted veins at the outlet of a tower fan, which can be directed to create focused or divergent airflow patterns through a sliding mechanism activated by a knob, allowing for various airflow settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional tower fan designs are used, then the structure is simple and easy to manufacture, but the airflow pattern cannot be manipulated or adjusted

Engineering Contradiction:
Improveairflow pattern manipulationVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the veins pivotally mounted rather than fixed, allowing them to rotate and change position. This enables the airflow pattern to be dynamically adjusted from focused to divergent configurations, directly resolving the contradiction between adaptability and complexity by introducing controlled movement to a previously static structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the outlet structure into multiple independent veins that can be individually positioned. By dividing the outlet into separate controllable segments rather than a single fixed structure, the system gains versatility in airflow manipulation while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

2Productivity

If adjustable veins are added to manipulate airflow patterns, then airflow directionality and velocity can be enhanced, but the device complexity increases

Engineering Contradiction:
Improveairflow directionalityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the adjustment mechanism for multiple veins into a single integrated system controlled by one knob. This combining of control functions allows airflow directionality to be enhanced across multiple veins simultaneously without proportionally increasing complexity, as one control element manages the entire vein assembly

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The vein assembly serves multiple functions: it controls airflow direction, adjusts velocity distribution, and creates different airflow patterns (focused or divergent). This multi-functionality allows the added structural complexity to deliver multiple performance benefits simultaneously, improving productivity across several airflow parameters at once

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

AI summary

The present invention is related in general to air circulators, and in particular, to an air circulator with a vein control system to direct and adjust airflow patterns. According to an exemplary embodiment, the present invention provides adjustable, vertical veins that are attached to the outlet of a tower fan. According to a preferred embodiment, the veins are pivotally mounted in such a way that by turning a knob, the veins can either be directed into a focused air-flow pattern or adjusted to a divergent air-flow pattern, or at any setting in between.
