Solution Overview

Problem

Existing vehicle display systems face challenges in eliminating glare and misalignment caused by reflections and wind-induced disturbances, which affect the driver's and passenger's view, particularly in vehicles like cars, motorcycles, and aircraft.

Innovation Solution

A vehicle arrangement comprising a display device, a detection device (including cameras and sensors) to detect glare and misalignment, and a compensatory component that can move or alter its shape to block glare and adjust the display's position or orientation, optionally using a secondary display to maintain information visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the display is adjusted to direct or diffuse reflected solar light beams, then glare to the driver is reduced, but the information displayed becomes more difficult for the driver to grasp

Engineering Contradiction:

Improveglare to driverVSAvoidvisibility of displayed information

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The display surface is segmented into multiple independently adjustable segments. Each segment can be tilted or rotated separately to redirect glare away from the driver's line of sight while keeping other segments positioned for optimal information visibility. This allows selective adjustment of only the affected areas rather than the entire display.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display surface are given different adjustment properties. The portion of the display receiving direct sunlight is made adjustable to redirect glare, while other regions maintain fixed optimal positioning for information display. This localized adjustment preserves information visibility in non-glared areas.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If a positionally variable sunlight beam shielding hood is installed on the display screen, then shielding area can be adjusted to sunlight, but the hood may obstruct the visibility of the display

Engineering Contradiction:

Improvesunlight shieldingVSAvoiddisplay visibility

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The shielding hood is designed with dynamic adjustment capabilities, allowing it to change its position, angle, or transparency in real-time based on sunlight conditions. This enables the hood to provide maximum shielding when needed while minimizing obstruction to the display when sunlight is not a problem.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of using a physical hood that blocks light, an intermediary element such as an electrochromic layer or adjustable polarizing filter is introduced. This intermediary can dynamically control light transmission, providing sunlight shielding when required while maintaining full display visibility under normal conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the display position is automatically adjusted as a function of eye position and vehicle position, then glare prevention is improved, but the system complexity increases

Engineering Contradiction:

Improveglare preventionVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The display system incorporates self-adjusting mechanisms that automatically respond to detected glare conditions without requiring complex centralized control. Each display segment or shielding element can independently sense and adjust to minimize glare, reducing the need for sophisticated control systems while maintaining effective glare prevention.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses simple feedback mechanisms where sensors detect glare conditions and trigger automatic adjustment of the display or shielding elements. This feedback loop provides effective glare prevention through straightforward sensor-actuator connections rather than complex multi-parameter calculations.

Inventive Principle:

Principle #23Feedback
