Airflow Shaper for 360-Degree Tower Air Cleaner Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners, particularly tower types, have a large footprint relative to air volume capacity, are unidirectional, and do not uniformly clean or circulate room air due to their square or cylindrical shape, leading to limited air volume and cleaning capacity, as well as susceptibility to airflow blockage.
Innovation Solution
The airflow shaper, featuring a body with a central axis and a raised central region, transitions axial or radial airflow into radial or axial airflow, allowing for 360-degree air intake and exhaust, reducing energy requirements and noise, and enabling placement in any room location without orientation constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a square or cylindrical shape is used for the air cleaner body, then it is easy to accommodate rotating fan units and filter elements, but the floor footprint becomes large relative to air volume capacity
Solution Approach 1:
The patent transitions from traditional square/cylindrical horizontal airflow designs to a vertical tower configuration with airflow moving primarily in the vertical dimension. The airflow shaper redirects horizontal airflow from filters into vertical upward flow, allowing the air cleaner to achieve high air volume capacity within a compact vertical footprint, thus reducing the floor area occupied while maintaining manufacturing simplicity.
2Ease of manufacture
If traditional square or cylindrical air cleaners are used, then they can be manufactured easily, but they are unidirectional and must be properly positioned to avoid blocking inlet and outlet airflow
Solution Approach 1:
The patent employs asymmetric design in the airflow shaper geometry, with a raised central region that creates preferential vertical airflow paths. This asymmetric structure naturally guides airflow upward through the tower, allowing the device to function effectively regardless of its rotational orientation on the floor, thereby achieving 360-degree placement flexibility while maintaining ease of manufacture.
3Device complexity
If airflow travels laterally and strictly horizontally through the air cleaner, then the structure can be simple, but the air volume capacity and air cleaning capacity are limited
Solution Approach 1:
The patent introduces vertical airflow movement as a new dimension, transitioning from purely horizontal lateral flow to vertical upward flow through the tower structure. The airflow shaper redirects horizontal airflow from filter elements into vertical paths, significantly increasing the effective air volume capacity and cleaning capacity without substantially increasing device complexity.
4Productivity
If a tower structure with vertical airflow is implemented, then air volume capacity and cleaning capacity are enhanced, but the airflow transition from horizontal to vertical requires special components
Solution Approach 1:
The patent introduces an airflow shaper as an intermediary component between the horizontal airflow path and the vertical tower structure. This mediator component, featuring a raised central region, smoothly redirects horizontal airflow into vertical upward flow, enabling the tower configuration and high air volume capacity while minimizing the complexity increase through its integrated design.
