Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system relies on remote memory to store performance coefficients, then centralization and data security are improved, but system latency and unavailability increase when network connection is lost

Engineering Contradiction:

Improvesystem availabilityVSAvoiddetermination latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the storage system into two segments: remote memory for centralized data security and local memory for immediate access. The performance coefficient is stored in both locations, allowing the system to segment the data access paths - using local memory when available for zero-latency access and remote memory for centralized management, thereby resolving the contradiction between reliability and latency

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-loading performance coefficients into local memory before they are needed for determination. This advance preparation ensures that when the remote memory becomes unavailable, the local memory already contains the necessary data, eliminating determination latency and maintaining system availability

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the system stores all tire parameter values in remote memory, then data centralization is improved, but data access speed and system responsiveness decrease

Engineering Contradiction:

Improvedetermination speedVSAvoiddata storage requirement

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential performance coefficient from the large set of tire parameter values and stores it in local memory. This selective extraction allows rapid determination using minimal local storage while the complete dataset remains in remote memory, resolving the contradiction between determination speed and data storage requirements

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies local quality by storing different types of data in different locations based on their access requirements. Frequently accessed performance coefficients are stored locally with high-speed access characteristics, while the complete historical dataset remains remotely with centralized storage characteristics, optimizing both determination speed and storage efficiency

Inventive Principle:

Principle #3Local quality

3Reliability

If the system requires network connection to determine tire performance characteristics, then data accuracy is improved, but system robustness and operational continuity worsen

Engineering Contradiction:

Improvedata accuracyVSAvoidoperational flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements beforehand cushioning by maintaining a local backup of the performance coefficient in local memory. This protective measure ensures that when network connections fail, the system can continue operating with accurate data from local storage, thereby improving operational flexibility without sacrificing data accuracy

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The local memory acts as an intermediary between the tire monitoring device and remote memory. It mediates data access by providing a local cache that enables operations to proceed independently of network availability, thus improving adaptability while maintaining the accuracy benefits of centralized remote storage

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of determining a tire performance characteristic of a tire. The method includes determining that a remote memory, remote from a tire monitoring device associated with the tire, is unavailable, and the remote memory is configured to store a performance coefficient of the tire corresponding to performance of the tire during a first time period. Where the remote memory is unavailable, the method includes either calculating the performance coefficient at a remote device or, obtaining, using the remote device, the performance coefficient from a local memory of the tire monitoring device. The method includes obtaining, using the remote device and from the tire monitoring device, a plurality of values indicative of a tire parameter of the tire during a second time period, and determining, at the remote device and based on the plurality of values and the performance coefficient, the tire performance characteristic.
