Solution Overview

Problem

Existing methods for filling vehicle tires with pressurized air are often manual and lack accuracy in determining the correct tire pressure, which depends on tire and vehicle types, as well as load conditions, leading to potential errors in pressure settings.

Innovation Solution

A method and system utilizing image recognition software to capture and analyze tire and vehicle images, along with tire pressure tables, to automatically determine the correct tire pressure, which can be displayed or input into a filling system, considering vehicle type, load condition, and temperature for precise filling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual methods are used for filling vehicle tires, then the operation is simple to perform, but the accuracy of determining correct tire pressure is poor

Engineering Contradiction:
Improvetire pressure determination accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated optical system. Image capture devices photograph the tire pressure table, and image recognition software automatically extracts pressure data, substituting the manual reading and transcription process with optical character recognition and automated data processing.

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

Solution Approach 2:

The system performs self-service by automatically capturing images of the tire and vehicle, recognizing the tire type and vehicle model, retrieving the correct pressure data from the pressure table image, and providing the recommended pressure without requiring manual intervention for data collection or interpretation.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If automated image recognition is used to determine tire pressure, then the accuracy of tire pressure determination is improved, but the complexity of the system increases

Engineering Contradiction:
Improvetire pressure determination accuracyVSAvoidoperational simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical operations with an automated optical system. Image capture devices photograph the tire pressure table, and image recognition software automatically extracts pressure data, substituting the manual reading and transcription process with optical character recognition and automated data processing.

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

3Reliability

If manual tire pressure setting is used, then the process is quick and simple, but errors in pressure settings occur frequently

Engineering Contradiction:
Improvecorrect tire pressure settingVSAvoidtime for tire pressure determination
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs self-service by automatically capturing images of the tire and vehicle, recognizing the tire type and vehicle model, retrieving the correct pressure data from the pressure table image, and providing the recommended pressure without requiring manual intervention for data collection or interpretation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by capturing images of the tire pressure table and storing the pressure data in advance. When a tire needs filling, the system has already retrieved and prepared the correct pressure information, eliminating the need for manual lookup during the actual tire filling process.

Inventive Principle:
Principle #10Preliminary action
