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

VSEngineering 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

Engineering Contradiction:
Improvecollision resistanceVSAvoidvehicle weight
Core Design Contradiction:
StrengthVSWeight of moving object

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If a collision protection system is added to the vehicle side body, then collision resistance is improved, but device complexity increases

Engineering Contradiction:
Improvecollision resistanceVSAvoidsystem complexity
Core Design Contradiction:
StrengthVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvecollision resistanceVSAvoidspace occupation
Core Design Contradiction:
StrengthVSVolume of moving object

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.

Inventive Principle:
Principle #15Dynamics

4Strength

If the collision panel is made larger to provide better protection, then collision resistance is improved, but space occupation and device complexity increase

Engineering Contradiction:
Improvecollision resistanceVSAvoidpanel area
Core Design Contradiction:
StrengthVSArea of stationary object

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.

Inventive Principle:
Principle #1Segmentation

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.
