Solution Overview

Problem

Conventional technologies fail to assist vehicle occupants in safely exiting the vehicle by warning them of approaching vehicles from the blind spot before the door is opened, thus not preventing collisions effectively.

Innovation Solution

A safe exit warning apparatus and method that includes sensors to detect the occupant's position and intent to exit, as well as an approaching vehicle from the blind spot, using a controller to output warnings through speakers or vibrations to alert the occupant of potential collisions, adjusting warning sounds based on separation distance and switching warning sources as necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the conventional technology outputs a warning sound after the door opening is detected, then the occupant is warned about the approaching vehicle, but the collision cannot be prevented because the warning comes too late

Engineering Contradiction:
Improvecollision prevention effectivenessVSAvoidwarning timing
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of the occupant's exit intent through sensor monitoring before the door is actually opened. When an approaching vehicle is detected in the blind spot and the occupant shows intent to exit, the system issues a warning sound through speakers near the occupant's position, providing advance alert before the door opening action completes, thereby preventing collision

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the conventional technology maintains the door in a locked state to prohibit the occupant from getting out, then collision is prevented, but the occupant's legitimate exit is blocked

Engineering Contradiction:
Improvecollision prevention effectivenessVSAvoidoccupant exit convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system continuously monitors the occupant's position and door state through sensors, providing real-time feedback about the approaching vehicle's proximity. Based on this feedback, the system dynamically controls the warning output - issuing warnings when the vehicle is detected in the blind spot and the occupant intends to exit, and stopping warnings when the vehicle moves out of the detection area or the door is fully opened, thus balancing safety with convenience

Inventive Principle:
Principle #23Feedback

AI summary

A safe exit warning apparatus and method for an occupant may include a first sensor that detects position of the occupant in the vehicle, a second sensor that detects an approaching object from the vehicle's blind spot, a warning device that warns the occupant about collision with the object, and a controller that determines the occupant's intent to get out of the vehicle by monitoring the position of the occupant in the vehicle when the vehicle stops and that controls the warning device to warn the occupant about the collision with the approaching object.
