Pivotable Touchscreen Segments for Reliable Motor Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operator control and display devices in motor vehicles face challenges in providing reliable and ergonomic touch control, especially under conditions of vibrations and jolts during travel, as they lack tactile feedback and support, making precise and safe operation difficult without visual monitoring.
Innovation Solution
A proximity-sensitive and touch-sensitive touchscreen with pivotable segments that can be tilted or folded to form an operator control element, allowing for adjustable geometry and automatic pivoting upon object approach, providing tactile feedback and guiding the operator's finger for improved ergonomics and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat touchscreen is used, then the display area is simple and readable, but operator control is unreliable under vibrations and jolts
Solution Approach 1:
The touchscreen transitions from a static flat state to a dynamic folded state along a fold line when a finger approaches. This dynamic transformation creates tactile feedback and finger guidance structures that improve control reliability during operation while maintaining display readability
Solution Approach 2:
The fold line acts as an intermediary structure between the finger and the touchscreen surface. It provides tactile feedback and guides the finger during operation, serving as a mediator that enhances the interaction between the operator and the device
2Reliability
If the touchscreen is made rigid and flat, then manufacturing is simple, but tactile feedback is lacking
Solution Approach 1:
The touchscreen is segmented into multiple display areas that can be folded along a fold line. This segmentation allows the screen to transform from a flat rigid structure to a folded configuration that provides tactile feedback, while maintaining manufacturing simplicity through modular design
3Ease of operation
If the touchscreen remains flat, then display readability is maintained, but finger guidance is insufficient
Solution Approach 1:
The display area dynamically changes shape from flat to folded along the fold line in response to finger approach. This dynamic shape change provides finger guidance through tactile feedback while maintaining display readability in both configurations

AI summary
A proximity-sensitive and touch-sensitive screen includes a display area with first and second segments, the second segment arranged on the first segment along a contact line, on an operator control and display device. At least the second segment can be pivoted, along the contact line, with respect to the first segment to temporarily form an operator control element, thereby providing easier and more reliable operator control.
