Steam Iron Soleplate Recess Layout for Lower-Energy Steam Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional steam irons with a soleplate having a gliding surface representing at least 60% of the total surface are expensive to produce and offer only slightly superior ironing performance compared to traditional flat soleplates, while also being energy-inefficient.
Innovation Solution
A steam iron with a soleplate featuring a reduced gliding surface of less than 50% of the total surface, incorporating a recess for steam diffusion surrounded by the gliding surface, which increases vapor diffusion cavity area for better steam impregnation and traction on linen, enhancing ironing performance and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gliding surface represents at least 60% of the total surface of the soleplate, then the ironing performance is slightly superior to traditional flat soleplates, but the production cost is relatively expensive
Solution Approach 1:
The patent changes the key parameter from gliding surface area (60-75% in prior art) to recess area (50-80% of total surface), fundamentally altering the design approach while maintaining ironing performance and reducing production cost
2Reliability
If the gliding surface represents at least 60% of the total surface of the soleplate, then the ironing performance is slightly superior to traditional flat soleplates, but the energy consumption is higher
Solution Approach 1:
The patent changes the key parameter from gliding surface area (60-75% in prior art) to recess area (50-80% of total surface), fundamentally altering the design approach while maintaining ironing performance and reducing production cost
Solution Approach 2:
The recess structure creates periodic steam release patterns as the iron moves, with steam being generated and released in cycles that improve energy efficiency compared to continuous steam release from large gliding surfaces
3Reliability
If the gliding surface is reduced to less than 50% of the total surface, then the steam diffusion cavity surface is increased for better steam impregnation, but the friction force increases
Solution Approach 1:
The patent changes the key parameter from gliding surface area (60-75% in prior art) to recess area (50-80% of total surface), fundamentally altering the design approach while maintaining ironing performance and reducing production cost
Solution Approach 2:
The recess acts as a steam cushion chamber that generates pneumatic pressure to reduce friction between the soleplate and fabric, allowing the iron to glide smoothly despite the reduced gliding surface area
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 reduced gliding surface allows for increased steam impregnation and pressure on linen, resulting in improved ironing performance and energy efficiency, achieving equivalent results with lower steam flow rates and reduced power consumption.
Implementation Method 1
the recess forms a steam diffusion cavity which is surrounded by the gliding surface when the soleplate is applied against the laundry to be ironed
Implementation Method 2
the reduction of the gliding surface also makes it possible to increase the pressure exerted by the weight of the iron on the linen at the level of the gliding surface
Implementation Method 3
the gliding surface which dries the linen moistened by the steam diffused into the recess

AI summary
The iron has a soleplate (1) comprising a lower face with a sliding surface (11) that is in contact with a linen. A recess (10) of the lower face supplies vapor, where depth of the recess is of 1-5mm. The recess is bordered at a periphery by the surface so as to form a vapor diffusion cavity for diffusing the vapor, where the cavity is surrounded by the surface when the soleplate is applied against the linen to be ironed. The surface represents 50 percent of a total surface of the lower face. A base (10A) is constituted by a plane surface with vapor exit holes (12).
