Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of convenience functions into touch screens within vehicles poses safety risks due to difficulty in recognizing buttons by touch and complexity in mode selection, leading to potential driver distraction and prolonged learning times.
Innovation Solution
A mode controller system that utilizes a touch screen with a screen configuration device to enable simplified pattern recognition for mode selection, allowing drivers to quickly switch between modes by inputting predefined patterns, such as characters or drag directions, through a touch input screen on the vehicle's touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control buttons are integrated into the touch screen or softkey, then the device complexity is reduced and convenience functions are consolidated, but the ease of operation deteriorates due to difficulty in recognizing buttons by touch and increased complexity in mode selection
Solution Approach 1:
The touch screen is divided into multiple selectable regions, each corresponding to a specific mode or function. This segmentation allows the driver to quickly access different functions by selecting specific areas rather than navigating through complex menus, thereby improving ease of operation while maintaining the integrated touch screen design.
Solution Approach 2:
The system pre-arranges mode selection options in a simplified layout on the touch screen before the driver needs to select them. By preparing the interface in advance with clearly defined regions for different modes, the driver can make quick selections without experiencing the complexity of multi-step menu navigation during actual driving.
2Device complexity
If control buttons are integrated into the touch screen or softkey, then the device complexity is reduced, but the reliability deteriorates due to potential driver distraction and safety problems
Solution Approach 1:
The touch screen interface is segmented into distinct operational zones that correspond to different driving modes. This segmentation reduces the cognitive load on the driver by providing clear, separate areas for different functions, minimizing confusion and potential distraction while maintaining the space-saving benefits of touch screen integration.
Solution Approach 2:
The system dynamically adjusts the touch screen display to show only the most relevant mode options based on current driving conditions, thereby reducing the number of choices the driver needs to consider. This dynamic adaptation helps maintain safety by preventing information overload while preserving the flexibility of the integrated control system.
3Adaptability or versatility
If multi-stepped setting options are provided on the touch screen, then the adaptability is improved with more function options, but the ease of operation deteriorates due to prolonged learning time and difficulty in controlling options while driving
Solution Approach 1:
Multiple setting options are organized into segmented regions on the touch screen, with each region representing a different mode or function category. This spatial organization allows drivers to access various functions without navigating through multiple menu steps, maintaining adaptability while significantly reducing the complexity of operation and learning time.

AI summary
A mode controller for a vehicle, a method therefor, and a vehicle system are provided. The mode controller includes a screen configuration device that configures a touch input screen on a touch screen and a controller that detects a pattern of a touch input which is input through the touch input screen. A determination device compares the detected pattern of the touch input with a plurality of patterns which are previously defined for each mode to determine whether there is a pattern identical to the pattern of the touch input. A mode execution device executes a function of a mode defined in response to the pattern identical to the pattern of the touch input.
