Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating-type drying devices can damage objects due to mechanical forces exerted during the drying process, and they often inefficiently utilize space within the drying chamber.
Innovation Solution
A drying device with a non-rotating second drying rack system that uses hot air to dry objects, featuring a mesh body, guide rail, and a winder for efficient air flow and improved space utilization, while minimizing mechanical stress on the objects being dried.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating-type drying device is used to improve drying efficiency, then drying speed is improved, but the object to be dried may be damaged by mechanical force
Solution Approach 1:
The drying chamber is divided into multiple levels with separate drying racks, allowing objects to be dried in different zones without mechanical rotation. This segmentation enables efficient use of space while avoiding the mechanical forces that cause damage.
Solution Approach 2:
The patent replaces the mechanical rotation system with a stationary multi-level rack system. Instead of rotating the drum to achieve drying efficiency, the invention uses multiple fixed drying racks with improved air circulation to maintain high drying speed without mechanical stress on objects.
2Productivity
If a rotating drum structure is used to enhance drying capability, then drying efficiency is improved, but space utilization of the drying chamber becomes inefficient
Solution Approach 1:
The patent transitions from a single-level rotating drum to a multi-level vertical rack system. By utilizing the vertical dimension with multiple drying racks stacked at different heights, the invention significantly improves space utilization while maintaining drying efficiency through enhanced air circulation across multiple levels.
Solution Approach 2:
The drying racks are positioned nested within the drying chamber structure, with the second drying rack located above the first drying rack. This nested arrangement maximizes the use of available vertical space within the chamber, improving overall space utilization.
3Device complexity
If a single drying rack is used to simplify the structure, then device complexity is reduced, but drying efficiency and space utilization are limited
Solution Approach 1:
The drying system is segmented into multiple independent drying racks (first and second drying racks) positioned at different levels. Each rack can be independently configured, allowing for simplified individual structures while achieving high drying efficiency through the combined multi-level system.
