SafeExit — Intelligent Door Safety System

1. Problem Context

Rear-seat passengers often open doors without awareness of approaching vehicles, cyclists, or pedestrians — leading to “dooring” accidents.

This is a visibility + system feedback problem, not just user error.

2. Design Goal

Prevent unsafe door opening by introducing a real-time awareness + intervention system at the moment of exit.

3. Experience Overview (User Journey)

Flow:

1. Passenger reaches door handle

2. System scans surroundings

3. Risk detected → block + alert

4. Safe → allow door to open

4. Interaction Flow (Core Logic)

Passenger pulls door handle
↓
Sensor scan (side + rear proximity)
↓
Is object approaching?
/ \
YES NO
↓ ↓
Lock door Unlock door Alert user Open normally

State 2 — Risk Detected

Door temporarily locked

• Red LED indicator

• Voice alert:

  “Vehicle approaching, please wait”

State 3 — Waiting / Transitional

• Red blinking light

• Subtle ticking sound

• Indicates system is monitoring

6. Interface Touchpoints

Where the system appears:

• Door handle (primary interaction point)

• Side indicator / mirror light strip

• Optional dashboard notification

• Audio system (voice alerts)

Components:

• Proximity sensors (radar / ultrasonic)

• Object detection logic

• Door lock control system

• Audio + visual feedback layer

8. Design Principles

• Preventive > Reactive

• Minimal friction (only block when needed)

• Clear feedback (no ambiguity)

• Fail-safe (manual override always possible)

9. Edge Cases Considered

• Emergency exit → override unlock

• Slow-moving objects → allow with warning

• False detection → avoid over-blocking

• Night visibility → stronger light cues

10. Outcome (Concept Value)

A system that transforms a simple action (opening a door) into a context-aware safety interaction, reducing accidents and improving passenger awareness.
