Solution Overview

Problem

Current vehicle display systems lack enhancement in marketability, with limited flexibility and visual appeal in displaying information to drivers.

Innovation Solution

A vehicle display system featuring a movable body with an annular or non-annular frame that shifts between upright and tilt positions, utilizing a driving device and guide mechanism to adjust the display's orientation, allowing for enhanced visibility and aesthetic appeal by displaying information in a virtual image within the frame's inner region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the movable body is shifted between upright and tilt positions to enhance display visibility and aesthetic appeal, then marketability and visual appeal are improved, but noise and vibration are generated

Engineering Contradiction:

Improvedisplay flexibilityVSAvoidnoise and vibration

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The display device employs a movable body that can dynamically shift between upright and tilt positions, allowing the display orientation to adapt to different viewing conditions and enhance visual appeal while maintaining controlled movement through guide rails to minimize noise and vibration

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A guide device with guide rails and guided portions acts as an intermediary mechanism between the driving force and the movable body, ensuring smooth movement while suppressing noise and vibration generated during position transitions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a guide device with multiple rotating bodies is used to guide the movable body along the guide rail, then noise and vibration are suppressed improving durability, but device complexity increases

Engineering Contradiction:

ImprovedurabilityVSAvoidguide device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The guide device is segmented into multiple independent rotating bodies (first and second rotating bodies) that can rotate independently on the guided shaft, allowing each component to handle specific guidance functions while distributing mechanical stress to reduce wear and improve durability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotating bodies provide dynamic adaptation to movement variations, maintaining continuous contact with the guide rail through rotational freedom while suppressing noise and vibration, balancing complexity with reliability

Inventive Principle:

Principle #15Dynamics
