Telescopic Collision Panel for Vehicle Side Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side collisions in vehicles frequently result in significant deformation of the vehicle body, leading to high human casualties due to the vulnerability of the side face during collisions, necessitating an effective anti-collision system to enhance safety and reduce damage.
Innovation Solution
A vehicle side wing anti-collision system featuring a telescopic assembly and collision panel that extends from the vehicle side body when subjected to a collision, utilizing elastic members for automatic retraction and a controller for independent extension of telescopic mechanisms to form a protective arc-shaped barrier, thereby preventing deformation and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the vehicle side body is made more rigid to resist collision, then collision resistance is improved, but weight increases and space is occupied
Solution Approach 1:
The collision panel is designed to be dynamically changeable between a retracted state (when no collision occurs) and an extended state (when collision occurs). The telescopic assembly enables the panel to extend outward upon collision detection, providing enhanced protection only when needed, rather than permanently increasing vehicle weight and space occupation.
Solution Approach 2:
The collision panel is nested within the vehicle side body when not in use, housed in a groove that integrates it into the vehicle structure. The telescopic assembly allows the panel to be stored compactly within the vehicle's existing structure, minimizing space occupation during normal operation while enabling deployment when needed.
2Strength
If a collision protection system is added to the vehicle side body, then collision resistance is improved, but device complexity increases
Solution Approach 1:
The collision panel system is designed to be substantially automatic. The telescopic assembly responds to collision forces directly, extending the panel outward when collision occurs without requiring complex control systems. The elastic member provides automatic reset functionality, returning the panel to its retracted position after collision, eliminating the need for manual intervention or complex control mechanisms.
3Strength
If the collision panel always protrudes from the vehicle side body, then collision resistance is improved, but space occupation increases and aesthetics are degraded
Solution Approach 1:
The collision panel transitions from a static protruding design to a dynamic system that changes its position based on collision conditions. During normal operation, the panel remains retracted within the groove, maintaining vehicle aesthetics and minimizing space occupation. Upon collision, it extends outward to provide protection, demonstrating dynamic adaptability.
4Strength
If the collision panel is made larger to provide better protection, then collision resistance is improved, but space occupation and device complexity increase
Solution Approach 1:
The collision protection system is divided into multiple independent collision panels rather than one large panel. Each panel can be independently deployed and reset, allowing for more efficient space utilization and reduced overall complexity. The segmented approach enables targeted protection at specific vulnerable points along the vehicle side body.
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
The system effectively prevents side body deformation during collisions by rapidly extending protective wings, reducing injury risk and improving collision resistance, while maintaining a compact design that minimizes space occupation within the vehicle.
Implementation Method 1
an elastic member disposed inside the groove and connected to the collision panel in a fixed manner so that the collision panel always tends to retract into the groove
Implementation Method 2
wherein an elastic member is disposed inside the groove and connected to the collision panel in a fixed manner so that the collision panel always tends to retract into the groove, and used for automatic reset of the collision panel

AI summary
Disclosed is a vehicle side wing anti-collision system, including a telescopic assembly fixed on a vehicle frame; and a collision panel located in a groove of a vehicle side body and provided correspondingly to the telescopic assembly. The groove is provided with a connection hole and the telescopic assembly is extended out of the connection hole towards two sides in a transverse direction of the vehicle to drive the collision panel to extend out of the groove till protruding from the vehicle side body when the collision panel is subjected to a collision. Through the telescopic assembly and the collision panel, protection layers are formed on two sides of the vehicle, and thus the anti-collision ability of the vehicle side wing is enhanced.
