Solution Overview

Problem

Existing parking systems lack convenience for drivers in determining parking space status and automating the payment process, leading to inefficiencies and potential fines for late payments.

Innovation Solution

A device installed in the car with GPS, USB connectors, and a SIM card, uses WiFi or GSM to connect to cloud databases for parking space detection, emits sounds for payment reminders, and automatically debits using an electronic wallet via an app, with a built-in battery and gyroscope for autonomous operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual parking payment methods are used, then drivers can control the payment process, but the payment efficiency is low and time is wasted

Engineering Contradiction:

Improvepayment efficiencyVSAvoidtime spent on payment

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically detecting parking space status, calculating parking duration, and preparing payment transactions before the driver needs to pay. The gyroscope detects vehicle movement in advance to trigger the payment process, eliminating the need for manual intervention at the payment stage.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The payment system serves itself by automatically completing the entire payment workflow without driver intervention. The system detects parking status, calculates fees, and executes payments through electronic wallet integration, making the system self-sufficient and eliminating manual payment operations.

Inventive Principle:

Principle #25Self-service

2Productivity

If automatic payment systems are implemented, then payment speed is improved, but device complexity increases

Engineering Contradiction:

Improvepayment processing speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The device integrates multiple functions into a single unit: GPS for location tracking, gyroscope for movement detection, WiFi/GSM for communication, and electronic wallet for payment processing. This multi-functionality reduces the need for separate systems while maintaining automatic payment capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses intermediary technologies such as cloud-based electronic wallets and communication networks to bridge the gap between parking detection and payment execution. These intermediaries handle complex transactions remotely, reducing the complexity burden on the local device.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If drivers manually monitor parking status, then payment accuracy is maintained, but driver attention is required

Engineering Contradiction:

Improvepayment accuracyVSAvoiddriver convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system continuously monitors parking status through GPS and gyroscope sensors, providing real-time feedback on vehicle position and movement. This automatic feedback mechanism ensures accurate payment calculation based on actual parking duration without requiring driver attention or manual monitoring.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system replaces manual driver monitoring with automated sensor-based detection. The gyroscope and GPS subsystems mechanically detect vehicle movement and location changes, substituting human attention with reliable automated sensing to maintain payment accuracy while improving convenience.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
