Solution Overview

Problem

Existing electric irons face difficulties in easy assembly and efficient use of limited internal space for electrical connections, requiring multiple assembly steps and constrained installation space.

Innovation Solution

A one-piece electrical connection element designed as a square or cubic plug, arranged in a channel-shaped recess within the iron's base body, allowing for two-sided contact and optimized space utilization, with plug contacts for both mains and internal power supply, and conductor tracks for efficient heating element connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional electrical connection devices are used, then electrical connection functionality is achieved, but assembly complexity increases and assembly time is extended

Engineering Contradiction:
Improveassembly simplicityVSAvoidassembly steps
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple electrical connection components (plug contacts, insulation housing, strain relief elements, and positioning features) into a single integrated one-piece electrical connection element. This merging eliminates the need for multiple separate assembly steps, allowing the entire electrical connection assembly to be installed as one unit, thereby significantly simplifying the manufacturing process and reducing assembly time.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If electrical components are installed in the rear area of the iron, then electrical connection functionality is achieved, but available installation space is insufficient

Engineering Contradiction:
Improveinstallation space utilizationVSAvoidinstallation space
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent repositions the electrical connection element from the traditional rear area of the iron to the handle area, utilizing the three-dimensional space within the handle structure. This dimensional relocation allows effective use of previously underutilized space in the handle, thereby solving the space constraint problem in the rear area while maintaining all necessary electrical connection functionalities.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If multiple separate electrical components are used, then electrical connection functionality is achieved, but assembly time is extended

Engineering Contradiction:
Improveassembly speedVSAvoidassembly time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent integrates multiple electrical connection components into a single one-piece element that includes plug contacts, insulation housing, strain relief features, and positioning elements. This consolidation allows the entire electrical connection assembly to be installed in one operation, dramatically reducing assembly time and improving manufacturing productivity by eliminating repetitive assembly steps.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If electrical connection elements are installed in limited rear space, then electrical connection functionality is achieved, but space efficiency is reduced

Engineering Contradiction:
Improvespace utilizationVSAvoidinternal housing space
Core Design Contradiction:
Ease of manufactureVSVolume of stationary object

Solution Approach 1:

The patent relocates the electrical connection element from the constrained rear area to the handle area, where there is abundant three-dimensional space available. This spatial repositioning optimizes the overall space utilization of the iron by placing electrical components in an area with sufficient volume, thereby improving space efficiency and allowing better arrangement of other internal components.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
