Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle display systems do not effectively prioritize and display the most necessary information to the driver based on different driving situations, leading to potential confusion and safety issues.

Innovation Solution

A vehicle display control device that adjusts the display proportions of shift range and vehicle speed information based on the selected shift range and driving mode, ensuring that the most critical information is prominently displayed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display enlarges the shift range for a predetermined amount of time, then the driver can more easily comprehend the shift range, but the display cannot adapt to different driving situations where different information is most necessary

Engineering Contradiction:

Improveease of comprehensionVSAvoidadaptability to driving situations

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The display system dynamically adjusts the display proportions of shift range and vehicle speed information based on the detected driving situation. The processor changes display proportions in accordance with the type of shift range selected and driving mode, making the system adaptive rather than static. This resolves the contradiction by enabling the display to automatically prioritize different information based on real-time driving conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes display parameters (display proportions of different information regions) based on the shift range type and driving mode. By modifying display proportions as a variable parameter according to driving situation, the system achieves both ease of comprehension for current situation and adaptability to different situations.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If the display shows all information equally, then comprehensive information is provided, but the driver cannot easily comprehend the most necessary information in each driving situation

Engineering Contradiction:

Improveinformation completenessVSAvoidease of comprehension

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The display applies different display qualities (proportions) to different information regions based on their importance in the current driving situation. The shift range display region and vehicle speed display region are assigned different proportions locally, with the more critical information receiving greater display emphasis. This maintains information completeness while improving comprehension of critical information.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The display proportions are dynamically adjusted based on driving situation rather than remaining static. The processor detects the current shift range type and driving mode, then automatically adjusts which information receives greater display proportion, ensuring the most necessary information is always prominently displayed without losing other information.

Inventive Principle:

Principle #15Dynamics
