Iron Touch Control Interface with Integrated Light Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irons lack an intuitive and easily accessible user interface for setting and confirming heat settings, leading to user confusion and inefficiency during the ironing process.
Innovation Solution
The iron features a heat controller user interface with touch controls and light indicators on the handle, allowing users to easily change heat settings and receive instant feedback, along with a forward-facing light for illuminating textiles and a heating light for temperature range alerts, enhancing usability and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interfaces with separate controls and indicators are used, then the interface structure is simple, but the user experience is poor due to lack of instant feedback and accessibility
Solution Approach 1:
The patent merges the touch control and light indicator into a single integrated unit on the handle. Each touch control has an associated light indicator that provides instant visual feedback directly at the control location, eliminating the need for separate controls and indicators elsewhere on the device.
Solution Approach 2:
The patent adds a visual dimension to the tactile control interface by incorporating light indicators that illuminate in response to touch inputs. This creates a two-dimensional interaction surface (tactile + visual) on the handle, enhancing user feedback without adding physical depth or complexity.
2Loss of information
If multiple separate controls are provided for heat settings, then each control function is clear, but the user cannot easily confirm the selected setting
Solution Approach 1:
The patent implements immediate visual feedback by illuminating the light indicator associated with the selected heat setting directly on the touch control. This confirms the user's selection instantly at the point of interaction, eliminating information loss without requiring additional confirmation mechanisms.
3Ease of operation
If the user interface is located on the handle, then it is easily accessible, but the light indicators may not be visible to the user
Solution Approach 1:
The patent places light indicators locally at each touch control position on the handle, ensuring that the visual feedback is positioned exactly where the user's finger contacts the control. This local placement ensures both accessibility and visibility without requiring the indicators to be positioned elsewhere on the device.
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 improved interface enables users to easily select and confirm heat settings with visual feedback, ensuring correct temperature usage and reducing errors, thus improving the ironing experience.
Implementation Method 1
The top cover of at least some of the touch controls is made from a transparent material. Hereby a light can be located beneath the cover of the touch control. The light can then, when lit illuminate the cover of the touch control. Thus, lights can be provided beneath the transparent top cover. The lights can be Light Emitting Diodes, LEDs.
Implementation Method 2
the iron comprises a forward-facing light for illuminating a textile to be ironed
Implementation Method 3
a heating light is activated when the iron temperature is outside a range allowed for the heat setting selected by a user

AI summary
The invention relates to an iron (10) with a user interface (26). The iron comprises a heatable soleplate (14), a handle, and a heat controller user interface (26). The heat controller user interface comprises at least two different touch controls (28, 29) each corresponding to a different heat setting of the iron. The touch controls are also provided with a light indicator each and wherein the light indicators are configured to indicate the heat setting currently selected. Hereby an improved user interface can be provided in that the currently selected heat setting is displayed by the light indicator located on a touch control. This will enable the user to both in an easy manner change the heat setting and at the same time get instant feedback on the current heat selection. The control and feedback can then be performed via the same touch control used for changing the heat setting that controls the heat of the heatable soleplate.
