Laundry Appliance Rotary Interface for Mode and Time Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dryer control user interfaces are cumbersome and difficult for users to quickly and efficiently set modes of operation and times without secondary buttons or complex navigation.
Innovation Solution
A rotatable control knob that allows users to navigate through menus and submenus hierarchically, changing operation modes and associated time settings with single-direction turns, using a single control element to select from multiple modes and time increments without additional buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional control interfaces with multiple buttons and dials are used, then users can access multiple functions, but the interface becomes complex and difficult to operate
Solution Approach 1:
A single rotary control element performs multiple functions by detecting different rotation directions and sequences. The control element can select between first and second menus, navigate through options, adjust values, and access submenus, replacing what would traditionally require multiple buttons and dials
Solution Approach 2:
The control interface implements nested menu structures where submenus are contained within parent menus. The rotary control element allows users to traverse these nested levels by continuing rotation in the same direction to enter submenus and rotating in the opposite direction to return to parent menus, creating a hierarchical navigation system
2Adaptability or versatility
If multiple control elements are used to access different menus and settings, then comprehensive control is achieved, but device complexity increases
Solution Approach 1:
Multiple control functions that would traditionally require separate buttons, dials, or switches are merged into a single rotary control element. The control element detects rotation direction, rotation sequence, and rotation magnitude to differentiate between various control operations, consolidating the interface structure
Solution Approach 2:
The single rotary control element serves as a universal control mechanism that can access first menus, second menus, submenus, and adjust various parameters depending on the rotation pattern detected, replacing multiple specialized control elements
3Ease of operation
If a single control element is used to navigate menus and adjust settings, then ease of operation improves, but the ability to provide comprehensive control options may be limited
Solution Approach 1:
The control element's functionality dynamically changes based on the current state and rotation pattern. The control system detects whether the user is rotating in the first or second direction, whether they have entered submenus, and adjusts the available options and displayed information accordingly, allowing a single element to provide comprehensive control
Solution Approach 2:
The control system provides feedback through the display device showing which menu or submenu is currently active based on the rotation sequence. This feedback mechanism helps users understand their navigation position and available options, enabling comprehensive control through simple rotational inputs

AI summary
A control user interface for laundry appliances, such as a clothes dryer or washing machine, enables a user to control multiple modes of operation and a variable associated with at least one mode of operation by manipulating a single control element. In one arrangement, the variable is time and multiple time increments are associated with at least one mode of operation. One embodiment includes a rotatable single control knob. Upon detecting the rotation of the control knob, a determination is made whether the currently selected operation mode has associated operation times to be presented to the user. If no associated operation times are presented, the user interface display is updated to reflect the next mode of operation. The operation mode and operation times may be part of different display region within the dryer control user interface. Thus, multiple menus and submenus can be traversed and selected from using a single control knob, without the need for secondary buttons or a base cycle position to control the mode operation and time settings.
