Appliance Control Panel Illumination for Clear Option Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household appliances, such as washers and dryers, do not effectively communicate available options to users once a mode is selected, leading to confusion and the need for users to restart cycles or rely on trial and error to change settings, as they stop indicating available options after selection.
Innovation Solution
A user interface with a control panel that uses illumination sources to differentiate between available, selected, and unavailable options, maintaining this information throughout the operational mode until options become unavailable, allowing users to easily select desired settings without confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the appliance stops indicating available options after one option is selected, then the display complexity is reduced, but the user loses information about other available options and must rely on memory or trial and error
Solution Approach 1:
The patent applies local quality by using different illumination states for different options: selected options receive a first illumination state while other available options receive a second illumination state. This allows the display to maintain information about multiple available options simultaneously while distinguishing which one is currently selected, resolving the contradiction between reducing display complexity and preventing information loss.
2Loss of information
If the appliance indicates all available options continuously, then the user always has information about available options, but the display becomes overly complex and confusing
Solution Approach 1:
The patent resolves this contradiction by applying local quality through differentiated illumination states. Instead of treating all options uniformly, the system applies distinct visual states: a first illumination state for selected options and a second illumination state for other available options. This allows continuous information provision while maintaining display clarity through visual hierarchy.
Solution Approach 2:
The patent also applies periodic action by controlling when options are indicated as available. Options are indicated as available during specific periods (before the appliance enters an operating state or during pause states) and not indicated during other periods (when the appliance is actively operating). This temporal dimension adds another layer of information management without increasing spatial display complexity.
3Ease of operation
If the user must select each option in turn to determine availability, then the appliance uses simple indication methods, but the user experience becomes time-consuming and frustrating
Solution Approach 1:
The patent applies feedback by providing immediate visual information about option availability and selection status. The illumination sources continuously indicate which options are available and which is selected, allowing users to make informed decisions without trial and error. This feedback mechanism eliminates the need for users to systematically test each option, significantly reducing the time and effort required to select desired settings.
4Adaptability or versatility
If the appliance does not inform users of available option changes after cycle start, then the system operates simply, but users cannot make necessary adjustments during operation
Solution Approach 1:
The patent applies dynamics by making the option indication system adaptive to the appliance's operational state. The system dynamically adjusts what information is displayed: options are indicated as available before the appliance enters an operating state or when in a pause state, but not indicated when actively operating. This dynamic behavior allows the system to provide adaptability for option changes while maintaining simple operation during active cycles.
