Movable Air-Outlet Guide for Adaptive Drying Air Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying apparatuses have fixed air outlet areas, limiting the ability to adjust air speed or volume adaptively, resulting in low drying efficiency.
Innovation Solution
A drying apparatus with a movable guide member in the air-outlet channel that divides it into two sub-channels, allowing adjustment of air speed without changing the total air volume, using a rotation shaft to control the opening sizes of these sub-channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air outlet area is fixed, then the structure is simple, but the air speed cannot be adjusted adaptively resulting in low drying efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the guide member movable within the air outlet channel. The guide member can be adjusted to different positions to change the opening areas of sub-channels, transforming a static air outlet structure into a dynamic one that can adaptively control air speed while maintaining structural simplicity
Solution Approach 2:
The patent applies segmentation by dividing the single air outlet channel into multiple sub-channels through the guide member. This segmentation allows independent control of air flow paths, enabling adaptive air speed adjustment for different drying requirements while keeping the overall structure relatively simple
2Speed
If the air outlet area is changed to adjust air speed, then the air speed can be adjusted, but the air volume changes resulting in inefficient drying
Solution Approach 1:
The movable guide member creates dynamic sub-channels that can adjust air speed by changing flow path resistance and direction, not by changing the total outlet area. This allows air speed control while maintaining constant air volume
Solution Approach 2:
Instead of adjusting air speed by changing the cross-sectional area (2D adjustment), the patent uses the guide member to control air flow in a different dimensional approach - by directing air flow paths and creating pressure differences through the movable guide structure, thereby maintaining constant air volume while achieving variable air speed
