Solution Overview

Problem

Existing vehicle control devices with touchscreens can be distracting for drivers, requiring them to look at the screen to operate, which can lead to driver distraction and increased risk of accidents.

Innovation Solution

A vehicle control device featuring a touch-sensitive layer integrated with a transparent cover that provides tactile feedback and active haptic feedback, allowing users to interact with vehicle functions without looking at the screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a touchscreen display is used as the sole input device, then the control device can control a large number of vehicle functions with a single input device, but operation of the control device becomes complicated and requires full attention of the user

Engineering Contradiction:
Improvenumber of controllable functionsVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control device is segmented into multiple functional zones on the transparent cover, each zone corresponding to specific vehicle functions. These zones are arranged in a spatial layout that allows users to access different functions by touching different areas, effectively dividing the complex control interface into manageable segments that reduce operational complexity while maintaining versatility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension to the control interface by arranging control zones in specific geometric patterns on the transparent cover. This dimensional arrangement allows users to navigate and select functions through spatial positioning and gestures rather than complex menu navigation, reducing operational complexity while preserving the ability to control multiple vehicle functions

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If the control device is located in a place that is not easily visible for the driver, then it can be integrated into the vehicle structure, but the driver requires full attention to operate it safely

Engineering Contradiction:
Improveintegration into vehicle structureVSAvoiddriver distraction
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The transparent cover incorporates tactile feedback mechanisms that provide immediate physical response when touched, allowing drivers to confirm their input and navigate the interface through touch alone without visual confirmation. This feedback loop enables safe operation while the device remains integrated into the vehicle structure in locations that may not be easily visible

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control device provides self-guiding tactile cues through the transparent cover's surface features and haptic responses, allowing drivers to locate and operate controls through touch alone without needing to visually search for buttons or menus. This self-service capability reduces driver distraction while maintaining structural integration

Inventive Principle:
Principle #25Self-service

3Ease of operation

If tactile elements are added to the touchscreen surface, then passive guidance can be provided, but the device complexity increases

Engineering Contradiction:
Improvepassive guidance capabilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses a transparent cover with integrated tactile features that can be formed through molding or surface treatment of the cover itself, rather than adding separate tactile elements. This approach provides passive guidance through tactile feedback while maintaining a relatively simple overall structure, as the tactile features are incorporated into the existing transparent cover component

Inventive Principle:
Principle #30Flexible shells and thin films
