Tower Fan Display Module Placement to Avoid Airflow Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans for air conditioners lack a display mechanism that does not interfere with airflow and often have insufficient space for a heater within the air flow path, limiting their ability to provide intense airflow in narrow regions and integrate a heating mode effectively.
Innovation Solution
A fan apparatus design that incorporates a display module within the diffuser, allowing it to be positioned without interfering with airflow, and includes a heater in the air flow path, while reducing flow path resistance through a handle and utilizing the Coanda effect for efficient airflow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display module is added to the fan apparatus, then information display functionality is improved, but the display may interfere with the air flow path
Solution Approach 1:
The display module is positioned on the front surface of the housing in a region that does not overlap with the air flow path, utilizing the horizontal dimension rather than placing it within the vertical air flow channel. This spatial separation in different dimensions allows the display to show information without obstructing air flow.
Solution Approach 2:
The front surface of the housing is divided into distinct functional regions: an air flow path region and a display module region. This segmentation allows independent optimization of each region - the air flow path maintains its required geometry while the display module occupies a separate non-interfering zone.
2Device complexity
If the air flow path is reduced to a predetermined size, then the fan structure is simplified, but there is insufficient space for a heater in the air flow path
Solution Approach 1:
The air flow path is designed with multi-functionality to serve both as the primary airflow channel and as an integrated heating zone. By making the air flow path universal for both cooling and heating operations, the structure remains simple while accommodating the heater without requiring separate dedicated spaces.
3Ease of operation
If the distance between the blowing fan and air flow path is increased, then fan operation is simplified, but there is not enough space for a heater in the air flow path
Solution Approach 1:
The parameters of the air flow path are optimized to maintain an appropriate distance between the blowing fan and the air flow path for simplified operation, while simultaneously ensuring sufficient volume within the air flow path for heater integration. This involves adjusting the cross-sectional area and length parameters of the air flow path to satisfy both constraints.
