Solution Overview

Problem

Drivers struggle to intuitively understand the influence of the travel environment, such as wind, on their vehicle during navigation.

Innovation Solution

A vehicle display device that projects a virtual image onto the windshield, using display figures and animations to represent wind direction and speed, allowing the driver to visualize the wind's impact on their vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wind information is displayed using conventional text or simple icons, then the device complexity is low, but the driver cannot intuitively understand the wind's influence on the vehicle

Engineering Contradiction:
Improveintuitive understanding of wind influenceVSAvoiddisplay device complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the vehicle and wind effects in the heads-up display. Instead of showing abstract text or simple icons, the system projects a visual replica of the vehicle with animated wind effects (such as virtual wind blowing through the vehicle model) to intuitively demonstrate wind influence, thereby improving driver understanding without requiring complex additional hardware

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transitions from two-dimensional static icons or text displays to a three-dimensional virtual vehicle model with dynamic wind effects. By adding the dimension of virtual space and animation, the display conveys complex wind information (direction, strength, impact) in an intuitive visual manner that maintains ease of understanding while managing device complexity through software-based solutions

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

2Loss of information

If detailed wind information is provided to the driver, then the driver's understanding of travel environment influence is improved, but the information processing time increases

Engineering Contradiction:
Improvewind information comprehensionVSAvoidinformation processing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system pre-processes wind data and prepares virtual vehicle models with wind effect animations in advance. When wind information becomes relevant, the pre-prepared visualizations are immediately projected onto the heads-up display, eliminating the need for real-time computation during critical driving moments and reducing information processing time while maintaining comprehensive wind information delivery

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex computational information processing with intuitive visual metaphors. Instead of requiring the driver to interpret numerical wind data or complex graphical interfaces, the system uses animated wind effects visualized through the virtual vehicle model, allowing the driver to instantly grasp wind conditions through natural visual perception rather than cognitive processing of detailed information

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
