Solution Overview
Problem
Household appliances with touch-sensitive operating devices face challenges in efficient and user-friendly operation due to complex hierarchies of programs and settings, which can lead to user confusion and suboptimal performance, especially when considering individual user preferences and health conditions.
Innovation Solution
Incorporating sensors to measure biophysical properties and emotional states of users, allowing the appliance to adapt its operation and interface based on user-specific data, using elongated input objects and gesture recognition to simplify control and optimize settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touchscreen is used for controlling the household appliance, then the operation becomes convenient and rapid, but the complexity of the control interface increases when many programs and settings are available
Solution Approach 1:
The control unit stores multiple sets of parameter values for different programs in advance. When a user selects a program, the corresponding pre-stored parameter set is automatically applied, eliminating the need for users to manually configure each parameter and reducing the perceived complexity of the interface.
Solution Approach 2:
The system automatically selects and applies appropriate parameter sets based on the chosen program without requiring manual intervention. The control unit serves itself by managing the complexity of parameter configuration internally, allowing users to interact with a simplified interface.
2Adaptability or versatility
If a deep hierarchy of menus and windows is created to set all parameters, then all settings can be accommodated, but the program control speed decreases and user patience is tested
Solution Approach 1:
The control interface is segmented into program selection and parameter application layers. Users interact only with the program selection layer, while the control unit handles the complex parameter configuration in the background, separating user interaction from system complexity.
Solution Approach 2:
Each program is associated with a universal parameter set that can be automatically applied. This multi-functionality allows the system to handle diverse parameter configurations through a single program selection mechanism, eliminating the need for deep menu hierarchies.
3Ease of operation
If individual user preferences and health conditions are considered, then the operation becomes more personalized and user-friendly, but the complexity of the control system increases
Solution Approach 1:
The system incorporates sensors that detect user biophysical properties and provide feedback to the control unit. Based on this feedback, the control unit automatically adjusts program parameters and interface characteristics to match user needs, creating a personalized experience without requiring complex manual configuration.
Solution Approach 2:
Manual user input and configuration are replaced with automated sensor-based detection and control unit processing. The mechanical interaction of users navigating complex menus is substituted with electronic sensing and automatic parameter adjustment, simplifying the user experience.
