Molded Tank Strainer for Ironing Pump Filtration Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household ironing appliances with steam generators are expensive to manufacture due to complex and costly filtration systems, and manual assembly of filters can lead to malfunctions and incorrect assembly risks.
Innovation Solution
Integration of a filtration strainer molded directly into the tank wall during manufacturing, featuring a frustoconical shape with narrow slots for effective filtration, simplifying assembly and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate filter is manually assembled and connected to the pump supply circuit, then filtration of water is achieved, but manufacturing cost increases and assembly complexity increases
Solution Approach 1:
The filter is merged with the tank wall by molding it directly into the suction orifice structure. The filter becomes an integrated part of the tank wall rather than a separate component, eliminating manual assembly steps while maintaining filtration function. This is achieved through co-molding or insert molding techniques during tank manufacturing.
Solution Approach 2:
The filter is pre-formed as an integral part of the tank wall during the molding process. The filtration structure is created in advance as part of the tank manufacturing, eliminating the need for separate filter installation and connection operations during final assembly.
2Reliability
If a separate filter is manually assembled and connected to the pump supply circuit, then filtration of water is achieved, but manufacturing cost increases
Solution Approach 1:
The filter is merged with the tank wall by molding it directly into the suction orifice structure. This integration reduces the total number of parts and eliminates separate filter components, thereby reducing manufacturing cost while maintaining filtration reliability.
Solution Approach 2:
The tank wall serves multiple functions: it contains the water reservoir, provides structural support, and incorporates the filtration function through the molded-in filter at the suction orifice. This multi-functionality reduces the need for separate filtration components and lowers overall manufacturing cost.
3Reliability
If a separate filter is manually assembled and connected to the pump supply circuit, then filtration of water is achieved, but risk of incorrect assembly increases
Solution Approach 1:
The filter is merged with the tank wall by molding it directly into the suction orifice structure. This integration eliminates manual assembly operations, thereby completely removing the risk of incorrect assembly while maintaining reliable filtration function.
Solution Approach 2:
The filter is pre-formed as an integral part of the tank wall during the molding process. This preliminary integration ensures correct positioning and connection of the filtration structure, eliminating assembly errors that could occur with manual installation.
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 provides reliable filtration without manual assembly risks, reduces production costs, and ensures efficient steam generation for effective ironing performance.
Implementation Method 1
the strainer has a body of frustoconical shape comprising slots... the slots have a width of less than 1 mm and preferably of the order of 0.5 mm... Such a characteristic makes it possible to obtain a sufficiently fine filtration to retain the particles which could damage the pump
