Solution Overview
Problem
Existing laundry drying machines have complex structural constructions for water removal units, leading to high manufacturing costs and lengthy repair times due to their location, which complicates maintenance and reliability.
Innovation Solution
The water removal unit is integrated into the upper or lower shell of the dryer's basement, allowing easy access and minimizing the number of components that need to be removed for maintenance, with a coupling element that can be easily decoupled for repairs without disassembling the entire dryer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water removing unit is positioned in the basement portion of the dryer, then it can effectively collect and remove condensation water, but it requires removal of many components for access and repair
Solution Approach 1:
The basement is divided into an upper shell and a lower shell that can be separated from each other. The water removing unit is positioned in the lower shell, which can be independently removed to access the water removing unit without disassembling the entire dryer or removing numerous components.
2Ease of repair
If the water removing unit comprises multiple separate components, then it allows modular replacement, but it increases the number of parts and manufacturing costs
Solution Approach 1:
The support body is integrated with the upper shell as a single unified component. This merging reduces the total number of separate parts in the water removing unit while maintaining the ability to replace the pump unit independently, thereby simplifying the overall structure and reducing manufacturing costs.
3Ease of manufacture
If the support body is integrated with the upper shell, then the construction is simplified and manufacturing costs are reduced, but the pump unit becomes harder to replace
Solution Approach 1:
The basement is segmented into separable upper and lower shells, with the pump unit positioned in the lower shell. This allows the lower shell containing the pump unit to be independently removed for maintenance, preserving ease of repair while the support body remains integrated with the upper shell for manufacturing simplicity.
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
This design simplifies the construction and assembly of the dryer, reduces manufacturing costs, and enhances maintenance efficiency by allowing for quicker and more reliable repairs without the need to reposition the machine.
Implementation Method 1
a condensing device for removing moisture of moist air coming from the laundry container
Implementation Method 2
The water-removing unit preferably comprises pumping means which are advantageously activated on the base of the water level inside the collecting housing
