Tire Pressure Alert Timing to Reduce False Low-Pressure Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire inflation pressure management systems generate frequent alerts due to fluctuations in tire inflation pressure caused by vehicle driving or temperature changes, leading to user inconvenience.
Innovation Solution
A tire inflation pressure management system that includes an information acquisition unit to measure tire inflation pressure, an alert generation unit that generates alerts when the pressure falls below a set threshold, and an alert output unit that delays notifications for a predetermined period, reducing frequent alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert information is generated frequently when tire inflation pressure fluctuates, then tire safety is improved, but user convenience deteriorates due to troublesome notifications
Solution Approach 1:
The patent implements periodic action by introducing a predetermined period threshold that must elapse before alert information is output. The control unit accumulates alert generation requests over time and only outputs alerts when the time interval between consecutive alerts exceeds the predetermined period. This transforms continuous frequent alerting into periodic alerting, resolving the contradiction by maintaining safety monitoring while reducing notification frequency to improve user convenience.
2Loss of time
If alert information is output immediately when tire inflation pressure is low, then response time is improved, but notification frequency increases causing user inconvenience
Solution Approach 1:
The patent applies preliminary action by pre-setting a predetermined period threshold before alert output. The control unit continuously monitors tire inflation pressure and accumulates alert conditions over time, comparing against the predetermined period to determine when to output alerts. This preliminary setup allows the system to respond promptly to genuine issues while filtering out transient fluctuations, achieving timely response without excessive notifications.

AI summary
A tire inflation pressure management apparatus includes an information acquisition unit, an alert generation unit, and an alert output unit. The information acquisition unit acquires information on a tire inflation pressure measured by a sensor provided in a tire. The alert generation unit generates alert information when the tire inflation pressure acquired by the information acquisition unit is below a first threshold value smaller than an appropriate value of the tire inflation pressure. The alert output unit gives a notification outside after an elapse of a predetermined period to indicate that the alert information is generated by the alert generation unit during the predetermined period.
