Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blowers face challenges in effectively adjusting blowing direction and range, requiring movement of the device itself, which consumes excessive power and is not user-friendly.
Innovation Solution
A blower design featuring a vane and door mechanism that can be moved within the device to adjust airflow direction and range, utilizing Coanda effect for air distribution, while being hidden from the user's view and powered by various drive mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blowing device itself is moved or rotated to adjust blowing direction, then the blowing direction can be adjusted, but excessive power is consumed and the device complexity increases
Solution Approach 1:
The blowing device is segmented into a stationary housing and movable internal components (vanes and doors). The vanes and doors can be independently adjusted to control airflow direction without moving the entire device, reducing power consumption while maintaining directional control capability.
Solution Approach 2:
The patent introduces movable vanes and doors within the housing that can be dynamically adjusted to change airflow direction. These internal components are designed to be movable along curved paths or rotatable, allowing flexible directional control without requiring the entire device to be moved or rotated.
2Ease of operation
If the blowing device itself is moved or rotated to adjust blowing direction, then the blowing direction can be adjusted, but the device complexity increases
Solution Approach 1:
The device is divided into a simple stationary housing and separate movable internal components (vanes and doors). This segmentation allows the housing to remain structurally simple while the internal components handle the complexity of directional adjustment through their movable mechanisms.
Solution Approach 2:
The patent employs movable vanes and doors with curved guide paths or rotational joints that provide smooth airflow direction control. These dynamic internal components are integrated into a relatively simple housing structure, avoiding the need for complex external moving parts while achieving flexible directional adjustment.
3Use of energy by moving object
If vanes and doors are installed inside the upper body to adjust airflow, then blowing direction can be adjusted with reduced power consumption, but the moving parts may be visible to users
Solution Approach 1:
The vanes and doors are nested within the upper body housing, with the movable components positioned inside the housing structure. This nesting arrangement allows the moving parts to be concealed within the housing, making them invisible to users while still functioning to adjust airflow direction.
Solution Approach 2:
The housing acts as an intermediary structure that encloses the movable vanes and doors. This intermediate element shields the moving parts from external view while allowing them to perform their airflow control function, effectively hiding the mechanical complexity from the user.

AI summary
A blower is disclosed. The blower of the present disclosure comprises: a fan generating flow of air; a lower body providing an internal space in which the fan is installed, and having a suction hole through which air passes; an upper body being an upper body, which is installed over the lower body and forms a channel that communicates with the internal space of the lower body, and having a space formed through the upper body in a front-rear direction; a slit formed to pass through the upper body and discharging air flowing through the channel of the upper body to an outside of the upper body; and a vane or a door movably installed inside the upper body, and adjusting a flow direction of the air passing through the slit.
