Wireless Harness Retainer Disconnection Alert for Vehicle Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current restraining systems in vehicles lack efficiency and flexibility, failing to effectively prevent motion-related injuries during travel.
Innovation Solution
A retainer apparatus comprising a first and second retainer portion slidably attached to adjustable harness straps, equipped with wireless transceivers and sensors that detect disconnection and transmit warning signals to activate audible alerts, ensuring secure restraint of individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional restraining systems are used, then the structure is simple, but the safety monitoring capability is insufficient
Solution Approach 1:
The sensor performs preliminary detection of the harness strap connection state before motion-related injuries can occur. The wireless transceiver is ready to transmit warnings in advance, enabling proactive safety monitoring rather than reactive response
Solution Approach 2:
The sensor continuously monitors the connection state and provides feedback through the wireless transceiver to the controller, which then activates audible warnings. This closed-loop feedback system enables real-time safety monitoring and immediate user alerting
2Adaptability or versatility
If fixed restraining systems are used, then the device complexity is low, but the flexibility and adaptability are poor
Solution Approach 1:
The harness strap system allows dynamic adjustment of the retainer portion position along the strap length, enabling adaptation to different user sizes and restraint requirements. The sliding mechanism provides continuous adjustability rather than fixed positions
Solution Approach 2:
The retainer apparatus is divided into separate components including the retainer portion, sensor, and wireless transceiver, allowing independent adjustment and configuration. This modular segmentation enables flexible assembly and adaptation to different restraint scenarios

AI summary
A retainer apparatus including a first retainer portion, a second retainer portion, a wireless transceiver, and a sensor. The sensor includes a first sensor portion physically contained within the first retainer portion and a second sensor portion physically contained within the second retainer portion. The first retainer portion is removably attached to the second retainer portion. The sensor is configured to detect the first retainer portion being disconnected from the second retainer portion and generate a warning signal. The wireless transceiver is configured to wirelessly transmit the warning signal to a controller in a vehicle to activate an audible warning alert to warn a user in the vehicle of the first retainer portion being disconnected from the second retainer portion.
