Solution Overview
Problem
Conventional clothing drying apparatuses consume excessive energy regardless of laundry size and can damage items due to drum rotation, and stacked configurations are inefficient in terms of space usage.
Innovation Solution
A dual-type clothing drying apparatus with a new dry system flow channel design, featuring a stacked arrangement of integrated and separation types, utilizing a cover shelf with through holes and guide protrusions to optimize hot air flow and reduce energy consumption while preventing damage to laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a drum rotation system is used to dry laundry, then hot air can be evenly applied to the laundry, but the laundry may be entangled and damaged due to rotation
Solution Approach 1:
The patent extracts the drum rotation mechanism from the drying system and replaces it with a stationary drying chamber. Hot air is circulated through the chamber to dry laundry without mechanical rotation, eliminating entanglement and damage while maintaining uniform drying through proper air flow distribution.
Solution Approach 2:
The mechanical drum rotation system is replaced with a thermal convection system. Instead of mechanically moving the laundry through rotation, the patent uses hot air circulation and convection currents to achieve uniform drying, substituting mechanical action with thermal and fluid dynamics.
2Area of stationary object
If a dual-clothing drying apparatus is implemented in a stacked arrangement, then space utilization is improved, but the overall height becomes too high for installation spaces
Solution Approach 1:
The patent transitions from a vertical stacked arrangement to a horizontal side-by-side configuration. By changing the spatial dimension from vertical stacking to horizontal placement, the apparatus maintains dual-functionality while reducing overall height to fit installation spaces better.
Solution Approach 2:
The patent designs a universal drying apparatus that can function independently or be combined with another unit. Each drying machine can operate separately, allowing flexible installation configurations (vertical or horizontal) to adapt to different space constraints while maintaining full drying functionality.
3Ease of operation
If the same drying system is used for all laundry sizes, then the system is simple to operate, but excessive energy is consumed when drying small amounts of laundry
Solution Approach 1:
The patent divides the drying system into separate, independently operable units. Users can select only the necessary drying capacity (one or both machines), allowing energy consumption to match the actual laundry load size while maintaining simple operation through consistent interfaces across units.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances energy efficiency and prevents damage to laundry by optimizing hot air flow and reducing the overall size of the drying apparatus, making it more compact and usable in limited spaces.
Implementation Method 1
a hot air unit configured to supply hot air to an inside of the dry chamber through the discharge hole; and a cover shelf disposed in the dry chamber and having a plurality of through holes configured to allow the hot air, supplied by the hot air unit to a lower side of the cover shelf, to flow, through the plurality of through holes, from the lower side of the cover shelf to an upper side of the cover shelf
Implementation Method 2
a clothing drying apparatus is an apparatus for drying laundry by applying dry hot air to wet item to be dried (referred to as 'laundry' hereinafter) to evaporate moisture of the laundry
