Solution Overview

Problem

Current vehicle display systems lack the ability to provide distinct haptic feedback for different display areas and functions, limiting the driver's intuitive recognition of touch operations and restricting service flexibility due to fixed display positions.

Innovation Solution

A system and method that utilize a processor to provide different haptic feedbacks based on touch operation regions and functions by adjusting vibration frequency and strength, offering three-dimensional operation feelings and preset feedback modes, and analyzing user intent through touch input information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single unified haptic feedback is provided for the entire touch operation region, then the device complexity is reduced, but the driver's ability to intuitively recognize different display areas and functions deteriorates

Engineering Contradiction:
Improvedriver's intuitive recognition of touch operationsVSAvoidhaptic feedback control system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The touch operation region is divided into multiple segmented display areas, and haptic feedback is provided differently for each segment. The processor identifies which segment is being touched and provides corresponding haptic feedback, enabling the driver to intuitively recognize different display areas and functions through distinct tactile sensations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different haptic feedback characteristics (vibration frequency, amplitude, duration) are applied to different segments of the touch operation region based on their specific functions. This local differentiation allows the driver to distinguish between various control areas and functions through tactile feedback without increasing overall system complexity.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the display device is fixedly disposed in front of driver's seat and passenger's seat, then the device complexity is reduced, but the service flexibility and adaptability deteriorates

Engineering Contradiction:
Improveservice flexibility in display configurationVSAvoiddisplay positioning system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device is configured to be movable between different positions (driver's seat side and passenger's seat side) rather than being fixed. The processor detects the display's current position and adjusts the segmentation and haptic feedback provision accordingly, enabling flexible service adaptation while managing positioning complexity through automated control.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If haptic feedback is provided for each segmented display area and function, then the driver's intuitive recognition is improved, but the processing complexity and energy consumption increases

Engineering Contradiction:
Improvetouch operation recognition clarityVSAvoidprocessor energy consumption for haptic control
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system pre-configures haptic feedback parameters for different display segments and functions. When a touch input is detected, the processor quickly retrieves and applies the pre-determined haptic feedback for the specific segment, reducing real-time processing complexity and energy consumption while maintaining clear tactile differentiation for the driver.

Inventive Principle:
Principle #10Preliminary action
