Solution Overview

Problem

Conventional tire pressure monitoring systems require complex manufacturing and pairing processes to ensure unique identifiers are correctly assigned to transmitters, increasing costs and complexity.

Innovation Solution

A system where a receiver assigns unique identifiers to transmitters, eliminating the need for pre-configuration during manufacturing, using a programmable memory to store and transmit air pressure signals with corresponding unique identifiers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transmitters are pre-configured with unique identifiers during manufacturing, then the receiver can correctly identify and associate signals with specific transmitters, but the manufacturing process becomes complex and costly due to the need to ensure unique identifier assignment

Engineering Contradiction:
Improvesignal identification reliabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of the conventional approach where transmitters are pre-configured with unique identifiers during manufacturing, this patent inverts the process by having the receiver assign unique identifiers to transmitters after manufacturing. This is achieved through a pairing process where the receiver generates and transmits unique identifiers to transmitters, which then store them for signal association. This inversion eliminates the need for complex manufacturing processes while maintaining reliable signal identification.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If transmitters are pre-configured with unique identifiers, then proper transmitter-receiver pairing can be ensured, but the pairing process requires careful control to prevent identifier conflicts

Engineering Contradiction:
Improvepairing accuracyVSAvoidpairing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The receiver performs the function of assigning unique identifiers to transmitters during the pairing process, eliminating the need for external intervention or complex control mechanisms. The receiver generates unique identifiers autonomously and transmits them to transmitters, which automatically store them. This self-service approach simplifies the pairing process while ensuring accurate transmitter-receiver association without identifier conflicts.

Inventive Principle:
Principle #25Self-service

3Reliability

If unique identifiers are assigned during manufacturing, then transmitter identification is reliable, but costs increase due to additional manufacturing steps and quality control measures

Engineering Contradiction:
Improveidentifier assignment reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The unique identifier assignment is performed as a preliminary action during the pairing process rather than during manufacturing. The receiver prepares and assigns unique identifiers to transmitters before they are installed in the vehicle, ensuring reliable identification while avoiding the need for costly manufacturing modifications. This timing of the assignment action eliminates additional manufacturing steps and quality control requirements.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system and method for tire pressure monitoring. The system includes a receiver having a storage memory, and a transmitter corresponding to a tire. The storage memory includes a set of unique identifier. The transmitter includes a programmable memory. The receiver is configured to receive a signal, determine when the signal corresponds to a member of the set of unique identifiers, and process the signal when the signal corresponds to a member of the set of unique identifiers. The transmitter is configured to receive a unique member of the set of unique identifiers, store the unique member in the programmable memory, and transmit a signal corresponding to the unique member and the air pressure in the tire.
