Solution Overview

Problem

Vehicle displays often suffer from suboptimal ergonomics and crash safety issues due to fixed installations, which become outdated quickly compared to mobile device advancements, and integrating non-vehicle displays can obscure interior components and compromise safety.

Innovation Solution

A foldable mobile display device with a flap that can be fixed in a vehicle interior using a display interface with a recess and fixing device, allowing for ergonomic positioning and easy removal, decoupling development cycles between vehicle and display devices, ensuring crash safety and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed display is integrated into the vehicle interior, then the display is stable and secure, but the ergonomics and accessibility are suboptimal

Engineering Contradiction:
Improvedisplay stabilityVSAvoidergonomics and accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The display device is made dynamically adjustable through a flap mechanism that allows the display to be positioned at different angles and orientations. The flap can be folded to various positions, enabling occupants to optimize viewing angles and accessibility based on their seating position and preferences, thereby resolving the contradiction between stability and ergonomics.

Inventive Principle:
Principle #15Dynamics

2Reliability

If vehicle displays use fixed hardware installations, then the display is secure during crashes, but the display becomes outdated quickly due to short software development cycles

Engineering Contradiction:
Improvecrash safetyVSAvoidsoftware compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The display system is segmented into two independent parts: a fixed vehicle-integrated interface that ensures crash safety, and a removable mobile display device that can be easily replaced. The mobile device can be upgraded independently to match new software requirements while the fixed interface remains unchanged, resolving the contradiction between crash safety and software adaptability.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If an external display is integrated into the vehicle interior, then the display is easily accessible, but other components such as air vents are obstructed

Engineering Contradiction:
Improvedisplay accessibilityVSAvoidcomponent obstruction
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The mobile display device is designed to nest within a dedicated receiving area in the display interface. This receiving area is specifically shaped to accommodate the display device without obstructing surrounding components like air vents. The flap mechanism allows the display to be positioned optimally while maintaining clear passages for other vehicle components, resolving the contradiction between accessibility and component obstruction.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If a mobile display device is made removable for flexibility, then the display can be easily replaced and adjusted, but the crash safety is compromised

Engineering Contradiction:
Improvedisplay flexibilityVSAvoidcrash safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system separates the removable mobile display device from the fixed vehicle-integrated interface. The fixed interface remains securely anchored to the vehicle structure, ensuring crash safety, while the mobile device can be easily removed and replaced. The flap mechanism provides additional anchoring when the display is in use, maintaining safety during normal operation while preserving flexibility for replacement.

Inventive Principle:
Principle #1Segmentation
