Solution Overview

Problem

The challenge of efficiently accessing vehicles in dynamic parking environments where space availability changes over time, requiring subjective user judgment and manual intervention for remote control drive, is not reliably addressed by existing systems.

Innovation Solution

A parking system equipped with sensors, processors, and transmitters determines object distances and transmits alerts to user devices when access is impeded, enabling efficient remote control drive initiation without manual assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote control drive facilities are provided to extract the vehicle from a parking space, then the vehicle can be moved to another position where access is not impeded, but the user is required to return to the vehicle, assess the situation and act based on subjective judgment, which is time consuming

Engineering Contradiction:

Improvevehicle accessVSAvoidtime to access vehicle

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary assessment of the parking environment using sensors before the user needs to access the vehicle. It continuously monitors the distance to surrounding objects and determines in advance whether access will be impeded, so that when the user returns, the system has already evaluated the situation and is ready to provide immediate alerts or initiate remote control drive automatically.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user about the accessibility status of the vehicle through alerts and notifications. The sensor data is processed and communicated back to the user, enabling them to make informed decisions about whether remote control drive is needed without having to personally assess the situation.

Inventive Principle:

Principle #23Feedback

2Reliability

If the user returns to the vehicle to assess the situation manually, then subjective judgment can be made about access limitations, but this process is time consuming and cannot reliably predict access issues in dynamic parking environments

Engineering Contradiction:

Improveaccess assessment reliabilityVSAvoidtime for situation assessment

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system replaces the manual mechanical assessment process with an automated sensor-based detection system. Instead of the user visually inspecting and subjectively judging the parking environment, electronic sensors continuously measure distances to surrounding objects and the processor automatically determines whether access is impeded based on predetermined criteria.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-assessment of the parking environment without requiring user intervention. The sensors automatically monitor the surroundings, the processor evaluates the data against accessibility criteria, and the system can initiate remote control drive automatically, making the assessment process independent of human involvement.

Inventive Principle:

Principle #25Self-service

3Reliability

If continuous monitoring of parking environment is implemented to predict access issues, then reliable access prediction is achieved, but energy consumption increases

Engineering Contradiction:

Improveaccess prediction reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring instead of truly continuous monitoring. The sensors and processor are activated at intervals or triggered by specific events (such as when the vehicle is parked or when changes in the environment are detected), allowing the system to maintain reliable access prediction capability while reducing energy consumption during periods when monitoring is not strictly necessary.

Inventive Principle:

Principle #19Periodic action
