Drying Oven Air Outlet Segmentation for Adaptive Air Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying apparatuses have fixed air outlets, 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 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 air outlet channel is divided into multiple sub-channels by inserting a guide member, creating first and second sub-air-outlet channels with separate air outlets. This segmentation allows independent control of air flow paths while maintaining the overall结构简单性, enabling adaptive air speed adjustment to improve drying efficiency
Solution Approach 2:
The guide member is movably arranged in the air outlet channel, allowing it to be positioned at different locations to dynamically adjust the opening areas of sub-channels. This dynamic configuration enables adaptive control of air speed without changing the total air outlet area, resolving the contradiction between simple structure and adjustable performance
2Quantity of substance
If the air outlet area is increased to improve air volume, then the drying capacity increases, but the air speed decreases reducing drying efficiency
Solution Approach 1:
By segmenting the air outlet into multiple sub-channels, the patent maintains the total air outlet area (preserving air volume) while creating separate controllable paths. Each sub-channel can be adjusted independently to optimize air speed, allowing the system to maintain both high air volume and high air speed for improved drying efficiency
Solution Approach 2:
Different sub-channels can have different opening areas adjusted according to local drying requirements. The guide member allows selective adjustment of each sub-channel's air flow characteristics, enabling localized optimization of air speed while maintaining overall air volume, thus resolving the contradiction between quantity and speed
