Tire Pressure Alerts With Severity and Mounted Position Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems provide alarms for abnormal internal pressure without clear details, making it difficult for drivers and vehicle managers to determine if emergency maintenance is needed or if vehicle operation can continue.
Innovation Solution
A tire management device and method that includes a tire pressure monitoring system, a detection device, and an operation recorder to detect abnormal tire pressure, determine its severity, and provide detailed notifications to drivers and managers, allowing them to make informed decisions about vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tire pressure monitoring system issues an alarm for abnormal internal pressure, then the driver is warned of the abnormality, but the alarm does not provide details making it difficult to judge whether emergency maintenance is needed
Solution Approach 1:
The abnormal internal pressure condition is segmented into multiple severity levels (e.g., mild, moderate, severe) with distinct visual indicators. This segmentation allows the system to provide detailed information about the abnormality while maintaining clear alarm notification, enabling drivers to understand the specific condition without overwhelming information.
Solution Approach 2:
The system adds a visual dimension to the alarm notification by displaying severity levels and detailed pressure information on a display unit. This transforms the alarm from a simple auditory/visual warning into a multi-dimensional information presentation that includes quantitative data and severity assessment, allowing drivers to make informed decisions about maintenance needs.
2Device complexity
If the in-vehicle system provides only a basic alarm without details, then the system remains simple, but drivers and vehicle managers cannot make informed decisions about vehicle operation
Solution Approach 1:
The decision-making process is segmented into clear visual categories (e.g., different colors or icons representing different severity levels). This segmentation presents complex pressure information in an easily interpretable format, allowing drivers to quickly understand the condition and make informed decisions without requiring complex system analysis.
Solution Approach 2:
The display unit acts as an intermediary between the complex sensor data and the driver's decision-making process. It transforms raw pressure measurements into meaningful visual indicators and severity assessments, bridging the gap between system complexity and user-friendly information presentation.
3Ease of operation
If the system provides detailed information about abnormal pressure, then decision-making becomes easier, but the system complexity increases
Solution Approach 1:
The notification system segments information into hierarchical levels: basic alarm indication, severity level, and detailed pressure data. This segmentation allows the system to provide comprehensive information while maintaining a structured, easy-to-read presentation that does not overwhelm the user with undifferentiated data.
Solution Approach 2:
The system uses visual dimensions (display screens, color codes, graphical icons) to present detailed pressure information in an intuitive format. This dimensional transformation allows complex data to be conveyed through visual metaphors and structured layouts that are easier to process than numerical data alone.

AI summary
A tire management device (10) includes: an information acquisition section (131) that acquires mounted position information indicating a mounted position of a tire on a vehicle (20) and mounted tire information that is information on the state of the tire including internal pressure; a determination section (132) that determines an abnormal internal pressure of the tire based on the mounted tire information; and a notification section (133) that outputs the mounted position and an abnormal internal pressure determination result of the tire that has been determined to have an abnormal internal pressure to a notification destination.
