Blower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blowers require mechanical movement to adjust blowing direction or range, leading to inefficiencies in power consumption and difficulty in effectively adjusting blowing intensity.
Innovation Solution
A blower design incorporating multiple slits in the upper body that can be adjusted by a door mechanism, allowing for the generation of direct or indirect airflow using the Coanda effect, with slits that can be opened or closed to control airflow direction and range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a blower uses mechanical movement to adjust blowing direction or range, then blowing direction can be adjusted, but power consumption increases excessively
Solution Approach 1:
The blowing device is divided into multiple independent blowing holes instead of a single movable component. Each blowing hole can be independently controlled by opening or closing mechanisms, allowing directional adjustment without mechanical movement of the entire device, thereby reducing power consumption.
Solution Approach 2:
The blowing holes are designed to be dynamically openable and closable rather than fixed. This dynamic configuration allows the system to adjust blowing direction by controlling which holes are open, replacing the need for mechanical rotation or movement of the entire blowing device.
2Ease of operation
If a blower uses mechanical movement to adjust blowing direction, then blowing direction can be changed, but adjustment effectiveness is insufficient
Solution Approach 1:
By segmenting the blowing function into multiple independent blowing holes with different orientations, the system achieves more precise and effective directional control. The segmented approach allows air to be directed through multiple paths simultaneously, improving overall adjustment effectiveness compared to a single mechanical moving part.
Solution Approach 2:
The multiple blowing holes serve multiple functions: they can blow air in different directions simultaneously, provide redundant airflow paths, and offer flexible combination options for achieving various blowing patterns. This multi-functionality enhances adjustment effectiveness beyond what a single mechanical component can achieve.
3Adaptability or versatility
If multiple slits are formed in the upper body for airflow discharge, then airflow distribution is improved, but device complexity increases
Solution Approach 1:
The upper body is segmented into multiple slits or blowing holes that can be independently controlled. This segmentation improves airflow distribution by creating multiple discharge paths while maintaining relatively simple individual structures. The complexity is distributed across multiple simple components rather than one complex component.
Solution Approach 2:
Multiple slits are created as simplified copies of a basic opening structure rather than designing entirely new complex components. Each slit follows a similar simple geometric pattern, reducing design and manufacturing complexity while achieving improved airflow distribution through repetition and arrangement.
