Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens in electronic devices lack dynamic and adaptive display control mechanisms that respond to user inputs, temperature, and humidity, limiting their interactive and intuitive user experience.
Innovation Solution
An electronic device with a touch screen and a control unit that displays a semitransparent layer overlapped with a background image, allowing for dynamic changes in transparency based on user inputs, temperature, and humidity, including the display of weather-specific images and objects like water vapor or frost, and the movement of graphical objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen displays a semitransparent layer overlapped with a background image, then the user interface becomes more intuitive and interactive, but the display control mechanism becomes more complex
Solution Approach 1:
The patent applies dynamics by making the transparency of the semitransparent layer dynamically adjustable based on user inputs, temperature, and humidity. The control unit changes transparency levels in response to sensor data and user interactions, transforming a static display into an adaptive interface that evolves with environmental conditions and user behavior.
Solution Approach 2:
The patent utilizes parameter changes by modifying the transparency parameter of the semitransparent layer according to temperature and humidity values from sensors. The control unit adjusts transparency levels based on environmental parameters, creating a responsive display that adapts to changing conditions without requiring complex structural modifications.
2Adaptability or versatility
If the transparency of the semitransparent layer changes dynamically based on temperature and humidity, then the adaptability of the display is improved, but the device requires additional sensors and control mechanisms
Solution Approach 1:
The patent applies universality by integrating multiple functions into the control unit: it processes temperature data from the temperature sensor, humidity data from the humidity sensor, user input signals, and environmental information from external devices. The control unit universally manages transparency adjustments based on any of these input sources, reducing the need for separate dedicated control circuits for each sensor.
Solution Approach 2:
The system applies self-service by automatically adjusting the semitransparent layer transparency based on sensor inputs without requiring manual user intervention. The control unit continuously monitors temperature and humidity sensors and autonomously modifies display parameters, allowing the device to self-adapt to environmental conditions.
3Ease of operation
If the touch screen responds to user inputs by changing transparency of partial regions, then the interactivity is enhanced, but the control processing becomes more complex
Solution Approach 1:
The patent applies local quality by changing the transparency of specific partial regions of the semitransparent layer based on where user inputs are detected. Instead of uniformly adjusting the entire layer, the control unit selectively modifies transparency in the regions where users touch or interact, creating localized visual feedback that enhances interactivity without requiring complex global processing.
4Adaptability or versatility
If the display shows weather-specific images like water vapor or frost based on temperature, then the user experience becomes more immersive, but the display content management becomes more complex
Solution Approach 1:
The patent applies color changes by displaying different visual content (water vapor images when temperature is above freezing, frost images when at or below freezing) based on temperature sensor data. The control unit selects and displays appropriate weather-specific imagery that corresponds to current thermal conditions, creating an immersive experience that reflects environmental states through visual transformations.
Data Source
AI summary
A background image is displayed on a touch screen of an electronic device. Overlapped with the background image, a semitransparent layer is displayed. When a touch and drag action is detected from the semitransparent layer, the transparency of a touch and drag region is changed. Transparency of the semitransparent layer may be changed according to temperature or humidity.
