Solution Overview

Problem

Drivers face challenges in safely operating touch-sensitive input devices in vehicles without diverting their attention from the road, as they cannot easily feel or reach the exact location of these devices without looking at them.

Innovation Solution

A vehicle cabin unit with a permanently connected panel that includes a display and a touch-sensitive input surface, where the panel protrudes from the main body, allowing drivers to interact with vehicle subsystem controllers without taking their eyes off the road, using a touch-sensitive input surface that is part of the panel's free wall, which can be fixed or adjustable in position and orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If touch-sensitive input devices are used to replace physical push buttons, then device complexity is reduced and modern functionality is improved, but driver safety deteriorates because the driver cannot easily feel or locate the exact position of the touch-sensitive input device without visual attention

Engineering Contradiction:
Improveinput device structureVSAvoiddriver safety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

A physical guide element is introduced as an intermediary between the touch-sensitive input device and the driver's finger. This guide element protrudes from the control panel and serves as a tactile reference point, allowing the driver to locate and operate the touch-sensitive device without visual attention, thus maintaining safety while using modern touch-based technology

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the driver operates touch-sensitive input devices, then control functionality is improved, but the driver must divert attention from the road, worsening driving safety

Engineering Contradiction:
Improvecontrol accessibilityVSAvoiddriving safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The physical guide element acts as a mediator that enables tactile operation of the touch-sensitive device. By providing a tangible reference point that protrudes from the panel, the driver can locate and interact with the control without visual distraction, maintaining both ease of operation and driving safety

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the touch-sensitive input surface is integrated flush with the panel surface, then device complexity is reduced, but the driver cannot easily locate or reach the input surface without looking at it

Engineering Contradiction:
Improvepanel integrationVSAvoidinput location detection
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

A physical guide element protruding from the panel serves as an intermediary tactile marker. This element does not complicate the integrated design but provides the necessary tactile feedback for the driver to locate the touch-sensitive input surface without visual attention, thereby improving ease of operation while maintaining integration

Inventive Principle:
Principle #24Intermediary (Mediator)
