Solution Overview
Problem
Conventional blowers face challenges in effectively controlling wind direction and achieving indirect air flow, often requiring complex structural adjustments that consume excessive power and have limited stepwise control over blowing direction.
Innovation Solution
The blower design incorporates a unique configuration with two towers and an air flow converter system, utilizing guide boards and gears to change the air flow direction, allowing for both direct and indirect wind delivery with a single driving motor, enabling stable control of wind direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire blower structure is adjusted to control wind direction, then the blowing direction can be changed, but the device complexity and power consumption increase
Solution Approach 1:
The patent divides the air flow control function into separate segments by introducing adjustable guide boards within the blower structure. Instead of moving the entire blower, only the guide boards are adjusted to change wind direction. This segmentation allows independent control of air flow direction while keeping the main blower structure stationary, reducing overall device complexity.
Solution Approach 2:
The patent implements dynamic adjustability through movable guide boards that can be positioned at different angles. The guide boards are designed to be adjustable rather than fixed, allowing the air flow direction to be dynamically changed without moving the entire blower unit. This dynamic element provides versatility while maintaining structural simplicity.
2Adaptability or versatility
If the entire blower structure is adjusted to control wind direction, then the blowing direction can be changed, but the power consumption increases
Solution Approach 1:
By segmenting the control function to only the guide boards rather than the entire blower, the energy required for direction control is significantly reduced. Only the lightweight guide boards need to be moved, consuming minimal power compared to moving the heavy motor and housing.
Solution Approach 2:
The dynamic adjustment of guide boards allows for energy-efficient direction control. The guide boards can be positioned to optimal angles to maximize air flow efficiency in different directions, reducing the power needed from the motor while maintaining versatile blowing direction control.
3Ease of manufacture
If conventional structures are used for wind direction control, then the implementation is simplified, but the stepwise control ability is limited
Solution Approach 1:
The patent employs dynamically adjustable guide boards that can be positioned at multiple discrete angles, enabling stepwise control of the air flow direction. This dynamic positioning capability allows for fine-tuned directional control while maintaining a relatively simple implementation using basic mechanical adjustment mechanisms.
