Movable Touch Display Feedback for Vehicle Infotainment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operator control devices for infotainment systems in vehicles lack cost-effective solutions for providing both haptic and audible feedback, with complex mechanical actuators being expensive and purely audible feedback not offering haptic confirmation, which can distract drivers and reduce safety.
Innovation Solution
An operator control device featuring a movable touch-sensitive display that activates an actuating element, providing haptic feedback through movement and audible feedback through an audio device, with a control unit determining the actuation position and matching it to graphical control elements to output appropriate signals, allowing for intuitive operation without visual attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex mechanical actuator system is used to generate haptic feedback, then haptic feedback is provided, but the device becomes expensive and complex
Solution Approach 1:
The patent replaces complex mechanical actuator systems with a simpler mechanical resistance-based feedback mechanism. The touch-sensitive display device itself provides haptic feedback through predefined mechanical resistance during movement, eliminating the need for separate complex haptic actuators while maintaining cost-effectiveness.
Solution Approach 2:
The touch-sensitive display device serves dual functions: it detects user input through touch sensitivity and simultaneously provides haptic feedback through its own mechanical resistance during movement. This self-service approach eliminates the need for separate dedicated haptic feedback components.
2Device complexity
If purely audible feedback is used, then the device is simple and cost-effective, but the user does not receive haptic confirmation
Solution Approach 1:
The patent merges audible feedback with haptic feedback into a unified feedback system. Both feedback types are provided simultaneously through the same control device, creating a more comprehensive user confirmation system while maintaining relative simplicity and cost-effectiveness.
3Ease of operation
If the touch-sensitive display device is made movable to provide haptic feedback, then haptic feedback is achieved, but the device structure becomes more complex
Solution Approach 1:
The patent introduces controlled movement capability to the touch-sensitive display device, allowing it to move between at least two predefined positions. This dynamic capability enables haptic feedback through mechanical resistance during movement while maintaining a relatively simple structural implementation.

AI summary
A method and an operator control device operate an infotainment system. The operator control device has a control unit, an audio device, an actuating element, and a touch-sensitive display device, which is mounted so as to be movable and is designed to display at least one graphical control element. The touch-sensitive display device moves during an actuating action and thus activates the actuating element. The control unit determines an actuation position of the actuating action on the touch-sensitive display device when the actuating element is activated and compares said actuation position with a display position of the at least one graphical control element. The audio device is actuated to output an audible signal when the actuation position matches the display position.
