Solution Overview

Problem

In car sharing systems, users often feel uncomfortable when route guidance to the return location is provided prematurely, especially when they take a detour or return to the same location where they started, as this unnecessary information is displayed at inappropriate times.

Innovation Solution

A shared vehicle management system that detects the user's intention to return the vehicle using various criteria such as distance, travel direction, and use history, and triggers route guidance only when the user is likely to return, ensuring the route is displayed at appropriate timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If route guidance to return space is provided automatically after vehicle rental, then users receive complete navigation information, but users feel uncomfortable when taking detours or returning to the same location

Engineering Contradiction:
Improveroute guidance informationVSAvoiduser discomfort
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts route guidance based on real-time detection of user return intentions. When the vehicle returns to the departure location or travel distance falls below a threshold, the system automatically suspends route guidance to the return space, adapting the information provision to the user's actual needs and avoiding unnecessary guidance during detours.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors travel distance and vehicle position to detect user return intentions. This feedback mechanism allows the system to adjust route guidance provision based on actual travel patterns, suspending guidance when the vehicle returns to the departure location or when travel distance is insufficient to indicate a genuine return need.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If route guidance is suspended when vehicle returns to departure location, then user discomfort is reduced, but route guidance may not be provided when needed

Engineering Contradiction:
Improveuser discomfortVSAvoidroute guidance availability
Core Design Contradiction:
Object-affected harmful factorsVSReliability
