Tire ID Registration System Using Temporary Storage and Frequency Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire identification code registration systems are prone to erroneous registration due to the reception of tire identification codes from nearby vehicles during the registration process, and they often require a sudden tire pressure decrease, which increases the burden on the registrant.
Innovation Solution
A tire identification code registration system that includes a storage manager to store candidate tire identification codes during a predetermined storage period and a deletion unit to eliminate non-corresponding codes, ensuring that only the correct tire identification codes are registered by distinguishing between vehicle-specific and external codes based on transmission frequency and travel status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the receiver immediately registers the first received tire identification code during registration, then the registration process is simple and fast, but erroneous registration occurs when another vehicle's code is received first
Solution Approach 1:
The receiver performs preliminary actions by storing received tire identification codes in a temporary storage area before final registration. Multiple codes are collected and stored temporarily, then the correct code is identified and registered after confirmation, preventing erroneous registration while maintaining efficiency
Solution Approach 2:
The system uses feedback mechanisms where the receiver monitors received codes, compares them against stored candidates, and confirms the correct code before final registration. This feedback loop ensures registration accuracy by verifying the received code matches the expected tire identification code
2Adaptability or versatility
If a sudden tire pressure decrease is performed during ID registration, then the registration can be triggered, but the burden on the person performing registration increases
Solution Approach 1:
The tire pressure monitoring system performs self-service by automatically detecting tire pressure changes and triggering the registration process without requiring manual intervention. The system monitors its own state and initiates registration when pressure changes are detected, eliminating the need for operators to deliberately cause pressure decreases
Solution Approach 2:
The system utilizes parameter changes in tire pressure as a natural trigger for registration. Instead of requiring manual pressure changes, the system detects spontaneous pressure variations and uses these parameter changes to initiate the registration sequence, reducing operational burden
3Reliability
If the receiver continuously monitors and stores all received tire identification codes, then registration accuracy improves, but memory usage and processing time increase
Solution Approach 1:
The receiver applies local quality by creating different storage characteristics for different codes. Frequently received codes (likely correct) are stored with higher retention priority in limited memory space, while rare codes are stored temporarily with lower priority. This selective storage approach maintains accuracy while optimizing memory utilization

AI summary
A tire identification code registration system for use with tire pressure detectors and a tire pressure monitoring system (TMPS) receiver. Each tire pressure detector, which includes a unique tire identification code, is coupled to a tire to detect the pressure of the tire and transmit a tire pressure signal. The receiver receives the tire pressure signal and monitors the pressure of the tire. The tire identification code registration system includes a storage manager that stores, in a memory, tire identification codes included in wireless signals received during a predetermined storage period as candidate tire identification codes. A registration unit registers the candidate tire identification codes in the memory as formal tire identification codes after the storage performed by the storage manager when the number of the candidate tire identification codes in the memory is equal to a predetermined storage number.
