Electric Iron Soleplate Front Sheet for Button-Area Ironing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric iron soleplate units are cumbersome for ironing fabrics near buttons and slide fasteners due to their thick design and wedge-shaped front structure.
Innovation Solution
A soleplate unit with a shallow groove on its bottom surface featuring a thin, tongue-shaped or V-shaped sheet extending outwardly, optionally with a high rigid surface layer, enhances accessibility and abrasion resistance for ironing delicate areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the soleplate unit is designed with a thick structure to accommodate the tubular electric heating element, then the structural strength and heating capability are improved, but the ability to iron fabrics near buttons and slide fasteners deteriorates due to the bulky front structure
Solution Approach 1:
The front portion of the soleplate is segmented from the main body through a shallow groove, allowing the front sheet to be thinner while the rear portion maintains sufficient thickness for housing the heating element. This segmentation enables the thick structure to coexist with the thin front edge capability.
Solution Approach 2:
Different parts of the soleplate have different thicknesses: the front sheet is thin (0.2-2.0mm) for maneuverability around buttons and fasteners, while the rear portion is thick to accommodate the heating element. This local quality variation resolves the contradiction between overall structural strength and local operational ease.
2Stability of the object's composition
If the front of the soleplate is designed as a wedge-shaped triangle, then the structural integrity is maintained, but the ironing capability near delicate fabric areas deteriorates
Solution Approach 1:
The wedge-shaped front structure is segmented from the main soleplate body, allowing the front sheet to be a separate, thinner component that extends forward. This maintains the overall structural integrity while enabling the front edge to be thin enough for delicate ironing work.
Solution Approach 2:
The front sheet has locally optimized thickness (0.2-2.0mm) compared to the thicker main body, providing the necessary structural integrity for the overall unit while enabling ease of operation in delicate areas through the thinner front portion.
3Ease of operation
If a thin sheet is used to extend the front of the soleplate, then the ease of ironing near buttons and slide fasteners is improved, but the abrasion resistance deteriorates
Solution Approach 1:
The front sheet is made of a thin layer (0.2-2.0mm) of high-rigidity, abrasion-resistant material such as stainless steel or aluminum alloy. This composite structure provides both the thinness needed for maneuverability and the surface hardness required for abrasion resistance, resolving the contradiction between ease of operation and reliability.
4Reliability
If the sheet material is made rigid to improve abrasion resistance, then the durability is improved, but the flexibility deteriorates
Solution Approach 1:
The front sheet has locally optimized material properties: it is thin (0.2-2.0mm) and made of high-rigidity material for abrasion resistance, yet remains flexible enough to follow fabric contours. The local quality variation in thickness and material composition resolves the contradiction between durability and flexibility.

AI summary
A soleplate unit of electric iron with improved front structure, comprising: a shallow groove provided on the bottom surface of the front side of the soleplate unit, a sheet set in said shallow groove and the front of the sheet extending outwardly from the front side of the soleplate unit. A high rigid surface layer is provided on the surface of the sheet, or the sheet is made of high rigid material. The sheet is tongue in shape, and two front sides of the sheet extend outwardly from the front side of the soleplate unit. The soleplate unit can also be provided with a sheet that extends outwardly from the front of the soleplate unit. It is very convenient for users to iron the face fabric near the button and the slide fastener.
