Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular-type drying apparatuses face inefficiencies in drying due to non-uniform wind emission, noise generation, and precision manufacturing requirements, particularly with polygonal shapes and recessed surfaces, which hinder vortex formation and increase production defects.
Innovation Solution
A cylindrical-shaped drying apparatus with a partitioned upper and lower compartment, featuring a rotationally installed drying target loading device and fans that utilize through-holes for air circulation, eliminating the need for recessed surfaces and allowing for uniform air flow and reduced noise, while heating lamps with high reflectivity ensure efficient and uniform drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a polygonal-shaped main body with recessed surfaces is used, then air flow introduction is improved, but manufacturing precision requirements increase and defects occur
Solution Approach 1:
The patent applies spheroidality by changing the main body shape from polygonal with recessed surfaces to a cylindrical shape with a smooth curved surface. This eliminates the need for precision-requiring recessed surfaces and angled holes, while still achieving uniform air flow distribution through the simplified circular geometry and evenly spaced introduction holes.
2Productivity
If a polygonal main body is used, then air flow can be introduced, but noise is generated due to non-uniform separation spaces
Solution Approach 1:
The cylindrical shape with constant radius eliminates the non-uniform separation spaces inherent in polygonal shapes. The uniform distance between the drying rack and main body wall throughout the rotation ensures consistent air flow characteristics, reducing turbulence and noise generation.
Solution Approach 2:
The patent achieves homogeneity by ensuring uniform separation spaces between the drying rack and main body wall through the cylindrical geometry. This uniformity in spatial distribution creates homogeneous air flow conditions, preventing the noise-generating turbulence that occurs in polygonal designs with varying gap sizes.
3Productivity
If recessed surfaces with precise angles are used, then vortex formation is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The cylindrical shape replaces complex recessed surfaces with inclined angles, simplifying the air flow introduction unit. Vortex formation is achieved through the rotational motion of the drying rack itself and the uniform air introduction through equally spaced holes, eliminating the need for geometrically complex recessed structures.
4Ease of manufacture
If a rectangular main body is used, then manufacturing is simpler, but drying uniformity decreases due to non-uniform air flow
Solution Approach 1:
The cylindrical shape with constant radius provides uniform separation spaces that ensure consistent air flow distribution to all parts of the drying rack. This curved geometry naturally achieves better drying uniformity compared to rectangular shapes, while remaining relatively simple to manufacture using standard cylindrical forming processes.
