User interface solutions for accessing appliance control through cosmetic outer cabinet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry appliances with concealed user interfaces require efficient access methods to modify operating conditions without opening the cosmetic outer panel, as existing solutions are cumbersome and time-consuming, potentially leading to ineffective cycles or damage.
Innovation Solution
The implementation of an intermediary interface within the cosmetic outer structure, which includes pressure sensors, strain gauges, and gesture-sensing mechanisms, allows users to interact with the user interface wirelessly or through mechanical engagement, enabling control of the appliance without opening the panel, including functions like pausing, starting, or stopping the cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the user interface is concealed within the cosmetic outer panel, then the aesthetic appearance is improved, but the ease of operation deteriorates
Solution Approach 1:
The user interface elements (buttons, display) are nested within the cosmetic outer panel structure. The control panel is integrated into the cosmetic panel itself, allowing the aesthetic cover to simultaneously serve as the functional interface housing, eliminating the need for separate access mechanisms.
Solution Approach 2:
A tactile sensor array is introduced as an intermediary between the cosmetic panel surface and the user. The sensors detect touch gestures on the cosmetic panel surface and translate them into control signals, allowing users to interact with concealed functions through the aesthetic panel without mechanical switches or exposed buttons.
2Shape
If the user interface is concealed within the cosmetic outer panel, then the aesthetic appearance is improved, but the device complexity increases
Solution Approach 1:
The cosmetic outer panel is designed to serve multiple functions simultaneously: it provides the aesthetic enclosure, houses the user interface elements, and acts as the interaction surface for tactile sensors. This multi-functionality reduces the need for additional components and simplifies the overall structure despite the concealed interface.
Solution Approach 2:
Traditional mechanical switches, exposed buttons, and separate control panel assemblies are replaced with a tactile sensor array integrated into the cosmetic panel. This substitution eliminates complex mechanical linkages and moving parts, reducing device complexity while maintaining the concealed aesthetic appearance.
3Strength
If the cosmetic outer panel is made thick for structural integrity, then the strength is improved, but the ability to access controls deteriorates
Solution Approach 1:
The tactile sensor array acts as an intermediary that requires minimal penetration depth into the cosmetic panel. Sensors can be positioned just beneath the panel surface, allowing the panel to maintain its structural thickness while still enabling effective touch interaction through the cosmetic surface.
Solution Approach 2:
Mechanical switches requiring physical access to recessed areas are replaced with capacitive or piezoelectric tactile sensors that can detect touches through the cosmetic panel surface. This substitution allows thick structural panels to maintain full control accessibility without compromising strength.
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
This solution provides quick and convenient access to the appliance's controls, reducing operation time and preventing damage or inefficiency, while maintaining the aesthetic concealment of the appliance within furniture-like designs.
Implementation Method 1
The cosmetic outer structure includes an outer panel and a top panel. A strain gauge is coupled to the outer panel, and wired or wirelessly interacts with the user interface when the outer panel is deflected a predetermined amount by application of pressure to the outer panel.
Implementation Method 2
A gesture sensing region is defined proximate the outer panel. The gesture sensing region is configured to wirelessly interact with the user interface when an obstruction engages the gesture sensing region.
