Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern motor vehicles require more complex operating systems, which can lead to driver distraction due to the complexity of multifunctional operating devices, necessitating an intuitive and simpler method for operating vehicle systems and functions.
Innovation Solution
A display and operating device with a touch-sensitive position detection unit and evaluation logic that evaluates touch positions in a time-resolved manner, allowing for the recognition of various user inputs, including movement sequences, speeds, and accelerations, and enabling the control of functions and systems through a touchscreen interface with movable objects and multiple display surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hierarchical menu structures are used for function calls, then the operating device can control multiple vehicle systems, but the operation complexity increases and driver distraction time increases
Solution Approach 1:
The patent applies dynamics by enabling objects on the display to be moved freely across multiple display surfaces through drag operations. This dynamic interaction allows users to intuitively select and control functions by physically moving objects to desired locations, replacing static hierarchical menus with dynamic, gesture-based control that reduces operation complexity while maintaining versatility
Solution Approach 2:
The patent extends the display interface across multiple display surfaces in three-dimensional space, allowing objects to be moved between surfaces. This dimensional expansion provides additional operational dimensions for controlling vehicle functions, enabling intuitive gestures that reduce driver distraction while accessing a comprehensive set of controllable systems
2Adaptability or versatility
If more operating elements are added to control complex functions, then more vehicle systems can be operated, but the installation space requirement increases
Solution Approach 1:
The patent implements multi-functionality by using a single display device that can present multiple objects representing different vehicle systems and functions. This universal interface allows control of numerous operable systems through software-based objects rather than physical operating elements, enabling high adaptability while maintaining a compact installation footprint
Solution Approach 2:
The patent uses visual copies or representations of vehicle systems as movable objects on the display. These digital copies allow users to interact with and control multiple vehicle systems through a unified interface, eliminating the need for separate physical controls for each system and thereby reducing installation space requirements
