Vehicle Alarming System Using Pressure Sensor and Paired Terminal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Strollers lack effective safety measures to prevent infants from being taken away or lost, as existing safety features do not adequately alert caregivers when an infant is removed or not present.
Innovation Solution
A vehicle alarming method and device that uses a pressure sensor to measure changes in weight and an intelligent communication module to detect the presence of a paired terminal within a preset distance range, triggering an alarm if the terminal is not detected, thereby alerting the caregiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure sensor is added to detect weight changes in the vehicle, then the ability to detect infant removal is improved, but the device complexity increases
Solution Approach 1:
The pressure sensor is integrated into the existing vehicle structure to serve multiple functions: it detects both the presence/weight of the infant and triggers the alarming system, eliminating the need for separate detection and alarm mechanisms. This multi-functional approach improves infant removal detection while minimizing additional complexity.
2Reliability
If an intelligent communication module is added to detect terminal presence, then the safety alert capability is improved, but the device complexity and cost increase
Solution Approach 1:
The intelligent communication module acts as an intermediary between the pressure sensor and the caregiver's terminal device. It receives weight change signals, determines whether the infant has been removed, and communicates this information to the caregiver's smartphone or other terminal, enabling remote alerting without requiring complex direct connection systems.
Solution Approach 2:
The system establishes a feedback loop where the pressure sensor continuously monitors weight, the communication module processes this data, and alerts are sent to the caregiver's terminal. This closed-loop feedback system ensures timely detection and notification of infant removal while maintaining system simplicity through automated decision-making algorithms.
3Loss of time
If real-time pressure monitoring and terminal detection are implemented, then the safety response time is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the pressure sensor operates in periodic cycles, checking weight at predetermined intervals. The system only activates the communication module and sends alerts when weight changes indicate infant removal. This periodic operation significantly reduces energy consumption compared to continuous real-time monitoring while maintaining rapid response capability.

Data Source
AI summary
A vehicle alarming method includes measuring a pressure value of a vehicle through a pressure sensor, detecting whether a paired terminal corresponding to the vehicle is within a preset distance range when the pressure value of the vehicle is reduced to a preset pressure range, and performing alarming when the paired terminal is not detected.
