Trunk-Mounted Warning Sign Case for Instant Emergency Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car safety warning signs are difficult to quickly deploy in emergency situations due to separate storage and require additional setup time, which can lead to delayed recognition by following vehicles, increasing the risk of secondary accidents.
Innovation Solution
A case with an integrally stored safety warning sign that automatically deploys by its own weight when the trunk is opened, utilizing a magnetic attachment system for easy and rapid installation at a high position, minimizing setup time and preventing sign fluttering with an elastic string and magnetic fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the safety warning sign is stored in a separate case, then the sign can be easily carried and stored, but it requires additional time to take out and install the sign in emergency situations
Solution Approach 1:
The safety warning sign is integrated directly into the trunk case structure, merging the storage function with the deployment function. The sign is positioned within the case body and automatically deploys when the case is opened, eliminating the need for separate storage and manual installation steps.
Solution Approach 2:
The safety warning sign is pre-positioned and pre-configured within the case body during manufacturing. The case structure itself is pre-prepared with slots and attachment points, so that when the case is opened in an emergency, the sign is already in the correct position for immediate deployment without requiring additional setup time.
2Ease of operation
If the warning triangle is manufactured in small sizes for convenience of carrying, then it is easy to store, but it is positioned lower than the driver's eye height when installed on the road, reducing visibility and effectiveness
Solution Approach 1:
The case is designed to be mounted on the trunk lid or upper portion of the trunk, utilizing the vertical dimension to achieve high positioning. When the case is opened, the safety warning sign deploys from this elevated position, ensuring that the sign is positioned at or above driver eye height for maximum visibility, while the compact case design maintains ease of carrying.
3Ease of operation
If the safety warning sign is integrated with the trunk, then it provides convenience for drivers when the trunk is opened, but it requires a large space for stowing and decreases spatial usefulness of the trunk
Solution Approach 1:
The safety warning sign is nested within the case structure, with the sign rolled or folded into a compact form that fits within the case body. The case itself is designed to be space-efficient, allowing it to be stored in the trunk without occupying excessive space, while still providing easy access and automatic deployment when needed.
4Speed
If the safety warning sign is mounted at various positions using magnetism, then it can be quickly installed, but it requires a separately prepared cylindrical case that takes additional time to open and deploy
Solution Approach 1:
The magnetic mounting mechanism and the case structure are merged into a single integrated unit. The case body includes magnetic attachment elements that allow the entire case to be mounted on the vehicle body at various positions using magnetism, eliminating the need for separate mounting steps and complex deployment mechanisms.
Solution Approach 2:
The case is designed with automatic deployment capability where opening the case automatically releases and deploys the safety warning sign without requiring additional manual operations. The magnetic mounting allows the case to be easily attached and detached by the user, while the deployment mechanism self-activates upon opening.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and secure deployment of the safety warning sign, improving recognition by following vehicles and reducing secondary accident risk by positioning the sign at a high visual height and stabilizing it against wind.
Implementation Method 1
a magnetic body embedded therein, and attaching and fixing the body to a trunk of a vehicle
Implementation Method 2
the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically deployed and installed by its own weight (gravity)

AI summary
A safety warning sign, when not in use, is rolled and stored inside to case, and in the event of emergency, when a driver opens the trunk and then opens the case by pulling a cover with a finger while the case is attached and affixed to the edge of the trunk by means of a magnetic body of an attachment member connected to the case, the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically spread open by its own weight (gravity) and deployed, thus allowing the driver, even in the state of panic from an accident, to easily and rapidly install the car safety warning sign and quickly escape to safety.
