Seat Belt Fastening Detection Module Wireless Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers in large transportation vehicles face challenges in remotely confirming whether passengers have fastened their seat belts, especially in large buses where direct visual checks are impractical and time-consuming.
Innovation Solution
A seat belt fastening detection module with a transmitting unit embedded in each seat belt buckle that generates an electric signal upon fastening, allowing a receiving unit to wirelessly transmit this information to a display unit, enabling the driver to remotely confirm seat belt status through a display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a driver directly checks whether passengers fasten seat belts one by one in a large bus, then the driver can confirm seat belt status, but the checking process becomes time-consuming and impractical
Solution Approach 1:
The patent divides the large bus into multiple zones with multiple receivers distributed throughout the vehicle. Each receiver independently detects seat belt fastening status in its local area, allowing parallel detection across the entire bus rather than sequential checking by the driver.
Solution Approach 2:
The system enables automatic detection of seat belt fastening status through transmitting units in buckles that actively send signals to receivers. The detection process occurs automatically without requiring driver intervention, transforming the system into a self-monitoring mechanism.
2Reliability
If a control system disables transportation means when passengers do not fasten seat belts, then safety regulation is enforced, but the driver cannot substantially check unfastening while the bus is travelling
Solution Approach 1:
The patent implements a feedback system where transmitting units continuously send seat belt status signals to receivers, which then provide real-time feedback to the driver through a display unit. This allows the driver to monitor unfastening events without leaving the driver's seat while maintaining safety enforcement capability.
Solution Approach 2:
The system introduces receivers and display units as intermediary components between the seat belts and the driver. These intermediaries transmit and present seat belt status information to the driver, enabling remote monitoring without requiring direct physical inspection.
3Extent of automation
If multiple receivers are distributed throughout the bus to detect seat belt status, then remote detection is enabled, but the device complexity increases
Solution Approach 1:
The patent designs receivers with multi-functional capabilities that can detect various seat belt statuses and potentially other safety parameters. Each receiver serves multiple detection purposes, reducing the need for separate specialized sensors for each function and thereby limiting the increase in overall system complexity.

AI summary
Provided is a module for detecting fastening of a seat belt, which enables a driver to detect whether passengers fasten seat belts in a transportation means including a plurality of seats and having many passengers, the module including: transmitting units configured to detect whether the passengers seated on the seats fasten the seat belts and selectively generate signals; a receiving unit configured to independently receive the signals transmitted from the transmitting units; and a display unit configured to display information about the seat, of which the passenger fastens the seat belt, to a driver through the information received from the receiving unit, in which the signals generated in the plurality of transmitting units are distinctly separated and transmitted.
