Household Iron Cord Design Using Shared LV Line for Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ironing systems require three sets of conductive wires and a flexible hose for HV power, LV supply, and data transmission, making the cord thick, bulky, and stiff, which impairs handling and is awkward and dangerous for users to change operating parameters.
Innovation Solution
A household electrical system with a cord comprising a first set of conductive wires for HV transmission, a second set for LV power, and repurposing the second set as a third data transmission line, using a modulator to activate and modulate voltage/current for two-way communication, reducing cord diameter and stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional electrical line is added for data transmission, then two-way data transmission between base and appliance is enabled, but the cord becomes thicker, bulkier, and stiffer
Solution Approach 1:
The second electrical line is designed to serve dual purposes: providing low-voltage power to the circuit board and enabling two-way data transmission between the base and the iron. This multi-functionality eliminates the need for a separate dedicated data transmission line, thereby maintaining cord flexibility and ease of handling while achieving full data communication capability.
Solution Approach 2:
The patent combines the power supply function and data transmission function into a single electrical line (the second set of conductive wires). By merging these two functions, the system reduces the total number of wires required, resulting in a thinner, more flexible cord that is easier to handle during ironing operations.
2Adaptability or versatility
If three sets of conductive wires and a hose are used, then all functions (HV power, LV supply, data transmission) are provided, but the cord diameter increases and stiffness increases

AI summary
The invention relates to a household electrical system, for example for ironing, comprising an appliance, such as an iron, connected to a base by a cord made up of at least: —a first electrical line formed by a first set of conductive wires for high-voltage (HV) transmission of a heating power, —a second electrical line formed by a second set of conductive wires for the low-voltage (LV) power supply of an electronic board arranged in the appliance, —a third electrical line for providing two-way data transmission between the base and the appliance; characterised in that the third electrical line is formed by the second set of conductive wires; the system also comprising a modulator suitable for modulating the voltage and/or the current circulating in the second set of conductive wires, so as to activate the second electrical line and the third electrical line or the third electrical line exclusively.
