Solution Overview
Problem
Conventional blowers face challenges in effectively controlling the blowing direction, particularly in providing both direct and indirect air flow, and require complex structural adjustments that lead to difficulties in stepwise control and excessive power consumption.
Innovation Solution
A blower design featuring a lower case with an inlet and an upper case comprising first and second towers, with air flow converters that include guide boards, gears, and a motor to change the guide board's disposition, allowing for the control of wind direction using a single driving motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire structure disposition is changed to control blowing direction, then the blowing direction can be controlled, but the device complexity and power consumption increase
Solution Approach 1:
The guide board is divided into multiple segments that can be independently rotated around the tower axis. Each segment can be positioned separately to control air flow direction, allowing precise directional control without moving the entire blower structure. This segmentation enables stepwise adjustment of blowing direction while maintaining a fixed overall structure.
Solution Approach 2:
The guide board segments are made rotatable around the tower axis through a driving mechanism. This dynamic adjustment allows the blowing direction to be changed by rotating the guide board segments to different angular positions, providing flexible directional control without structural reconfiguration.
2Ease of operation
If the entire structure disposition is changed to control blowing direction, then the blowing direction can be controlled, but power consumption becomes excessive
Solution Approach 1:
Only the guide board segments need to be rotated to change blowing direction, rather than moving the entire blower structure. This localized movement significantly reduces the energy required for directional control, as the driving mechanism only needs to rotate lightweight guide board segments instead of heavy structural components.
Solution Approach 2:
The guide board acts as an intermediary element between the fixed blower structure and the air flow. By rotating the guide board segments, the blowing direction is controlled without moving the main structure, reducing power consumption while maintaining effective directional control.
3Adaptability or versatility
If conventional air discharging structure is used, then direct blowing can be provided, but indirect blowing capability is lost
Solution Approach 1:
The guide board segments can be dynamically positioned at different angular orientations to switch between direct and indirect blowing modes. When the guide boards are oriented to direct air flow toward the user, direct blowing is achieved. When positioned to redirect air flow along the tower surface, indirect blowing is enabled, providing versatility in air delivery modes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables stable and efficient control of both direct and indirect air flow by changing the guide board's disposition with a single motor, reducing power consumption and improving the blower's ability to provide comfortable air distribution.
Implementation Method 1
a fan that is disposed in the lower case and makes air introduced from the inlet flow to an upper side in which the first tower and the second tower are disposed, thereby making air flowing upward by the fan flow into the space between the first tower and the second tower
Implementation Method 2
a guide board that is disposed inside the first tower or the second tower or protrudes through a first wall or a second wall; an upper gear that rotates in engage with an upper portion of the guide board; a lower gear that rotates in engage with a lower portion of the guide board
