Solution Overview

Problem

Existing vehicle tire pressure monitoring systems only provide real-time alerts after a pressure loss occurs, failing to anticipate potential issues before departure, which can lead to critical situations on the road, compromising safety, comfort, and tire durability.

Innovation Solution

A pre-alert method that uses data processing to assess tire pressure data and route characteristics, such as distance, duration, and speed, to detect potential pressure issues before departure, allowing drivers to take corrective action before embarking on a journey.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time pressure monitoring is used to detect pressure loss, then safety risks are reduced during critical situations, but the system cannot provide early warning before departure

Engineering Contradiction:
ImprovesafetyVSAvoidearly warning capability
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary assessment of tire pressure conditions before the vehicle departs by analyzing pressure data collected during parking periods. This preliminary action enables early warning of potential pressure issues before the journey begins, allowing drivers to take preventive measures rather than reacting to critical situations during travel.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system calculates a risk score based on pressure evolution patterns detected during parking periods and compares it against threshold values. This preliminary risk assessment is completed before departure, providing advance warning without requiring continuous real-time monitoring during the journey, thus resolving the contradiction between early warning capability and safety monitoring.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If continuous real-time monitoring is implemented, then critical pressure loss can be detected immediately, but the system cannot assess potential issues before the journey begins

Engineering Contradiction:
Improvepressure loss detection accuracyVSAvoidpre-departure pressure trend data
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system collects and analyzes pressure data during parking periods before the journey begins, building a historical pressure evolution profile. This preliminary data collection enables the system to detect gradual pressure changes and predict potential issues before departure, complementing real-time monitoring rather than replacing it.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous pressure monitoring across different states (parking and driving), ensuring that both pre-departure trends and real-time conditions are captured. This continuous action provides both historical context for prediction and immediate detection capability, resolving the contradiction between measurement precision and information availability.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If the system only alerts after pressure loss occurs, then false alarms are minimized, but drivers cannot take preventive corrective actions

Engineering Contradiction:
Improvedriver response simplicityVSAvoidtire condition safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system generates a pre-departure alert when pressure evolution patterns during parking indicate a high risk of pressure loss during the journey. This preliminary alert allows drivers to take corrective actions such as inflating tires or delaying departure before the actual pressure loss occurs, enhancing safety while maintaining simple driver response protocols.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system takes preliminary anti-action by warning drivers of potential pressure issues before they manifest as critical problems during travel. This preliminary warning enables preventive measures to be taken, counteracting the potential harmful effect of pressure loss before it occurs, thus improving reliability without complicating driver operations.

Inventive Principle:
Principle #9Preliminary anti-action
