Blower with Movable Damper for Adjustable Airflow Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers lack a mechanism to control the direction of airflow, limiting their ability to efficiently circulate air and provide airflow to users in indoor spaces.
Innovation Solution
The blower design incorporates a damper and bar mechanism that allows for adjustable airflow direction, with a fan generating air flow through a lower body and upper bodies featuring discharge holes, enabling the blower to direct airflow either forward or upward by moving the damper and bar to control airflow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional blower design without airflow direction control is used, then the device structure is simple, but the airflow distribution and circulation efficiency are limited
Solution Approach 1:
The patent applies the dynamics principle by making the damper movable rather than fixed. The damper can rotate around the discharge hole to change airflow direction dynamically. This allows the blower to adapt airflow direction to different user needs while maintaining a relatively simple overall structure, resolving the contradiction between operational flexibility and structural simplicity.
Solution Approach 2:
The patent segments the airflow control function by introducing a separate damper component that can independently adjust the discharge hole's airflow direction. This segmentation allows airflow direction control without requiring complex reconstruction of the entire blower structure, thus improving ease of operation while keeping device complexity manageable.
2Adaptability or versatility
If a fixed discharge hole design is used, then the manufacturing process is simple, but the adaptability to different user needs is poor
Solution Approach 1:
The discharge hole is designed with a movable damper that can rotate to different positions, transforming a static structure into a dynamic one. This allows the same discharge hole structure to serve multiple airflow direction needs, improving adaptability without significantly complicating the manufacturing process.
Solution Approach 2:
The damper-equipped discharge hole structure serves multiple functions: it can direct airflow forward, upward, or in intermediate directions. This multi-functionality is achieved through a relatively simple structural modification, making the discharge hole adaptable to different user needs while maintaining ease of manufacture.
3Productivity
If no airflow direction control mechanism is provided, then the device complexity is low, but the productivity of air circulation and user service is limited
Solution Approach 1:
By introducing a rotatable damper, the system gains dynamic airflow direction control capability. This simple dynamic mechanism significantly improves air circulation efficiency and user service productivity by enabling targeted airflow delivery, without adding substantial device complexity.
Solution Approach 2:
The patent implements a partial control mechanism (damper at discharge hole) rather than controlling the entire airflow path from the fan. This partial action approach achieves significant productivity improvement in airflow distribution while minimizing the added device complexity.
