Telescopic Flasher for Vehicle Emergency Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle emergency safety devices are difficult to attach to a vehicle and require drivers to exit and place warning triangles, which can lead to secondary accidents due to obstructed views and increased risk during emergency stops.
Innovation Solution
A vehicle emergency safety device using a selfie stick with a telescopic support stick, fixing clamps, a joint, and a rotatable cradle to easily attach and deploy a flasher on a vehicle door, providing a visible warning to following vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning triangle is placed behind the stopped vehicle, then following vehicles can be warned of the emergency situation, but the driver must exit the vehicle and place the triangle manually, which increases the risk of secondary accidents
Solution Approach 1:
The device automatically deploys the warning signal without requiring driver intervention. When the vehicle stops, the flasher unit is automatically positioned on the vehicle exterior and activated, eliminating the need for the driver to manually place warning triangles and reducing exposure to traffic hazards.
Solution Approach 2:
The device is pre-positioned within the vehicle and automatically deployed when needed. The flasher unit is stored in a ready-to-deploy position and automatically extends to the optimal location on the vehicle exterior when the vehicle stops, ensuring immediate warning without driver action.
2Illumination intensity
If the vehicle stops on the road shoulder, then the driver can check the vehicle error or breakdown, but the view may be obstructed and following vehicles may not recognize the stopped vehicle in advance
Solution Approach 1:
The flasher unit uses alternating red and blue LED lights that create a highly visible flashing pattern. The changing colors and flashing nature of the lights ensure that the stopped vehicle is easily recognizable from a distance, overcoming the obstructed view problem on road shoulders.
Solution Approach 2:
The flasher unit employs periodic flashing of red and blue LEDs to create a highly noticeable warning signal. The alternating light pattern draws attention from following drivers and ensures the stopped vehicle is recognized in advance, even when partially obscured by terrain or vegetation.
3Ease of operation
If a traditional warning triangle is used, then it can reflect light from headlights, but it requires manual placement 100-200m behind the vehicle and cannot be easily attached to the vehicle
Solution Approach 1:
The flasher unit combines the warning signal function with direct vehicle attachment. The device integrates the light-emitting components, battery, and mounting mechanism into a single unit that attaches directly to the vehicle exterior, eliminating the need for separate warning triangle placement and retrieval operations.
Solution Approach 2:
The device is pre-positioned within the vehicle and automatically deployed when needed. The flasher unit is stored in a ready-to-deploy position and automatically extends to the optimal location on the vehicle exterior when the vehicle stops, ensuring immediate warning without driver action.
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 rapid and secure attachment to a vehicle door, enhancing visibility of emergency situations to following drivers from a distance, reducing the risk of secondary collisions and eliminating the need for manual placement of warning triangles.
Implementation Method 1
a first adjusting screw 250 penetrating through the fixing member upper recess 211 and the hinge member lower part 221 inserted into the fixing member upper recess 211, thereby adjusting an angle of the hinge member 220 in one direction by a threading of the first adjusting screw 250
Implementation Method 2
a second adjusting screw 260 provided in the hinge member upper recess 222 and having an upper part provided in the hinge member upper recess 222, thereby rotating the cradle 300 by 360° and fixing it at any angle
Implementation Method 3
an elastic ring 180 made of an elastic material, wherein the elastic ring 180 is fitted over the first pole 110 or under the fourth pole 140 in an expanded or contracted state in a radial direction of the first pole 110 or the fourth pole 140
