Solution Overview

Problem

Users of vehicles undergoing unattended parking may feel uneasy about the status of their vehicles moving unmanned, as there is no direct visual feedback or information provided to the users.

Innovation Solution

A vehicle information delivery device equipped with an image processing unit and an information sending unit, which generates vehicle-related images based on camera images taken in a predetermined target area and sends this information to a display terminal recognized by the user, such as a mobile terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If unattended parking is performed without providing vehicle status information to users, then the parking process is fully automated and efficient, but users feel uneasy about their vehicles moving unmanned

Engineering Contradiction:
Improveunattended parking automationVSAvoidvehicle status information
Core Design Contradiction:
Extent of automationVSLoss of information

Solution Approach 1:

The system captures camera images of the vehicle during unattended parking, processes these images to generate vehicle-related images showing the vehicle's status and position, and sends these images to the user's display terminal. This feedback loop provides users with visual information about their vehicle's condition during automated parking, reducing anxiety while maintaining full automation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The image processing unit acts as an intermediary between the automated parking system and the user. It transforms raw camera images into meaningful vehicle-related images that convey status information, serving as a mediator that bridges the gap between the unmanned system and user awareness without requiring direct user involvement in the parking process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If camera images are captured and processed to provide vehicle status information, then user awareness and confidence improve, but system complexity increases

Engineering Contradiction:
Improveuser confidence in unattended parkingVSAvoidimage processing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system creates visual copies of the vehicle's actual status through vehicle-related images generated from camera images. These images are sent to the user's terminal, providing a replicated visual representation of the vehicle's condition without requiring the user to physically observe the vehicle, thus building confidence while keeping the system manageable.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system replaces the need for direct mechanical observation or manual vehicle checking with an automated image capture and processing system. Cameras and image processing units substitute for human visual inspection, providing status information automatically without requiring user intervention or complex mechanical monitoring systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If vehicle status information is sent to user terminals during parking, then user anxiety is reduced, but information transmission and processing time increases

Engineering Contradiction:
Improvevehicle monitoring reliabilityVSAvoidinformation delivery time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system captures camera images at periodic intervals during the unattended parking process and sends vehicle-related images to the user's terminal at these intervals. This periodic information delivery keeps users informed about vehicle status without requiring continuous image transmission, balancing monitoring reliability with time efficiency.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The image processing unit prepares and processes vehicle-related images in advance during the parking operation, so that status information is ready for immediate transmission to the user. This preliminary processing ensures that when information needs to be delivered, it is already prepared, minimizing transmission delays while maintaining continuous monitoring.

Inventive Principle:
Principle #10Preliminary action
