Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers do not evenly distribute clean air in the vertical direction, leading to intensive supply of clean air to local areas, and lack a structure that minimizes flow resistance and noise generation.
Innovation Solution
The blower design includes a lower case with a suction port, a fan, an upper case with a discharge port, and flow guides that extend across the discharge port to guide air upward, along with a heater and radiating fins for heat dissipation, and a diffuser to guide air discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional blowers supply clean air through discharge ports, then clean air is supplied to indoor spaces, but the air distribution is intensive and localized rather than even in the vertical direction
Solution Approach 1:
The discharge port is divided into multiple segments arranged vertically, with multiple flow guides positioned at different heights. Each flow guide segment handles air flow to a specific vertical zone, transforming the single concentrated discharge into multiple distributed discharge points that achieve even vertical air distribution
Solution Approach 2:
Flow guides are positioned at different vertical locations with different orientations and angles tailored to local requirements. Lower flow guides direct air horizontally while upper flow guides direct air obliquely upward, creating locally optimized flow patterns that collectively achieve uniform overall distribution
2Manufacturing precision
If flow guides are added to guide air flow, then air distribution uniformity is improved, but device complexity increases
Solution Approach 1:
Flow guides are designed with curved surfaces that smoothly guide air flow from the fan outlet to the discharge port. The curved geometry naturally directs airflow without requiring complex mechanical components, achieving effective flow guidance while maintaining structural simplicity
Solution Approach 2:
The flow guides serve multiple functions simultaneously: they guide airflow direction, distribute air vertically, reduce turbulence, and minimize flow resistance. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity
3Manufacturing precision
If flow guides are positioned close to the discharge port, then air flow guidance is effective, but flow resistance and noise generation increase
Solution Approach 1:
Flow guides are positioned dynamically at optimal distances from the discharge port, neither too close nor too far. The spacing allows air to expand and stabilize before being guided, reducing turbulence and flow resistance while maintaining effective flow direction control
Solution Approach 2:
Flow guides act as intermediary structures between the fan outlet and the discharge port, providing a transition zone that smoothly redirects airflow. This intermediary positioning reduces abrupt flow changes, minimizing noise generation and flow resistance while maintaining guidance effectiveness
