Solution Overview

Problem

Existing portable emergency situation display devices for vehicles face issues such as exposure and damage of warning display units, inaccurate angle maintenance, and instability due to external impacts and irregular ground surfaces, which hinder effective communication of emergency signals to rear vehicles.

Innovation Solution

A portable emergency situation display device with a case that covers the warning display unit, a spring-elastic angle adjustment mechanism for maintaining the correct angle, and a retractable movement prevention unit to stabilize the device, ensuring the warning display unit remains protected and securely positioned.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the warning display unit is kept exposed for visibility, then emergency signals are more visible, but the warning display unit is damaged by external impacts

Engineering Contradiction:
Improvevisibility of emergency signalsVSAvoiddamage to warning display unit
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The warning display unit is nested inside the case body, which protects it from external impacts. The unit can be extended outward when needed for visibility, and retracted when not in use to prevent damage. This nesting structure allows the device to maintain both protection and visibility capabilities.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If the warning display unit is fixed rigidly to maintain angle, then angle accuracy is maintained, but the device cannot adapt to irregular ground surfaces

Engineering Contradiction:
Improveangle accuracy of warning display unitVSAvoidadaptability to irregular ground
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The case body is designed with flexibility to bend and adapt to irregular ground surfaces. The warning display unit is connected through a hinge structure that allows angular adjustment, enabling the unit to maintain its display angle while the base adapts to various terrain conditions. This dynamic design resolves the contradiction between fixed angle precision and ground adaptability.

Inventive Principle:
Principle #15Dynamics

3Weight of moving object

If the case structure is simplified for portability, then ease of carrying is improved, but stability on irregular ground deteriorates

Engineering Contradiction:
Improveportability of display deviceVSAvoidstability on irregular ground
Core Design Contradiction:
Weight of moving objectVSStability of the object's composition

Solution Approach 1:

The display device is segmented into modular components including the case body, warning display unit, and movement prevention units. This segmentation allows the main body to remain lightweight and portable, while separate stabilization components can be deployed when needed. The modular structure maintains portability while providing stability through deployable support elements.

Inventive Principle:
Principle #1Segmentation

4Volume of moving object

If the movement prevention unit is made retractable for compact storage, then portability is improved, but the unit becomes less effective at preventing movement

Engineering Contradiction:
Improvestorage compactnessVSAvoideffectiveness of movement prevention
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The movement prevention unit employs a retractable design with elastic members that allow it to be compact during storage and extend when deployed. The elastic components provide automatic engagement and disengagement capabilities, ensuring reliable movement prevention when extended while maintaining compact form for portability. The dynamic extension and retraction mechanism resolves the contradiction between compact storage and effective stabilization.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to an portable emergency situation display device for a vehicle, the device having a cover that closes the upper part of a case so that a warning display unit is not exposed to the outside when the warning display unit and a road safety image display unit are accommodated in the case, and thus damage to the warning display unit is prevented, wherein the warning display unit is fixed, at a certain angle, to an angle adjustment protrusion, formed on a support, while moving and rotating by means of spring elasticity, so as to maintain an accurate angle and prevent movement of the warning display unit, and a movement prevention unit is mounted at the lower part of the case so as to be exposed or retracted, thereby supporting the lower part of the case and minimizing shaking.
