Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Vehicles navigating spiral ramps face challenges in avoiding collisions with side walls and curbstones due to limited visibility of the rear wheel, leading to potential damage and increased driver anxiety.

Innovation Solution

An apparatus and method that includes a spiral ramp determining module, side mirror control module, collision determining module, and steering guide module, which use camera images to recognize spiral ramp direction, calculate curvature, predict collisions, and automatically adjust side mirrors and steering to prevent collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the driver concentrates on monitoring the rear wheel contact with the curbstone, then the visibility of the rear wheel is improved, but the vehicle may collide with the outer wall or opposite vehicle causing big damage

Engineering Contradiction:

Improvevisibility of rear wheel positionVSAvoidcollision avoidance

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The side mirror acts as an intermediary device to provide the driver with visual information about the rear wheel position relative to the curbstone. By adjusting the side mirror to a lower angle, the driver can indirectly monitor the rear wheel contact point without needing to directly focus on it, thus maintaining awareness of both the rear wheel position and the outer wall distance

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system provides continuous visual feedback to the driver through the adjusted side mirror, allowing the driver to monitor the distance between the rear wheel and curbstone in real-time. This feedback mechanism enables the driver to make timely steering adjustments to avoid collisions while maintaining proper vehicle positioning

Inventive Principle:

Principle #23Feedback

2Stability of the object's composition

If the steering device is insufficiently turned, then the vehicle can maintain stable positioning, but the corner portion of the vehicle body collides with the outer wall

Engineering Contradiction:

Improvevehicle positioning stabilityVSAvoidcollision with outer wall

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary assessment of the steering angle and vehicle position before collision occurs. By monitoring the distance between the vehicle corner and outer wall in advance, the system can prompt the driver to adjust the steering angle proactively, preventing collision before it happens while maintaining stable vehicle control

Inventive Principle:

Principle #10Preliminary action

AI summary

An embodiment apparatus for assisting driving of a vehicle on a spiral ramp includes a spiral ramp determining module configured to determine whether a vehicle travels on a spiral ramp that guides rotation of the vehicle in a specific direction, by using an image of the spiral ramp acquired by a camera included in the vehicle, and a side mirror control module configured to automatically lower a side mirror installed on a side of the vehicle to which the vehicle rotates to an angle to show a view of a rear wheel in response to a determination that the vehicle travels on the spiral ramp.
