Smart Helmet Wear Detection with Buckle and Lock Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders often fail to wear helmets correctly, compromising head protection during transportation vehicle use due to improper practices such as hanging the helmet on the vehicle or not securely fastening the strap, which increases the risk of head injury.
Innovation Solution
A smart helmet system with detection modules to monitor the connection state of the helmet lock, wearing state of the helmet, and engagement state of the helmet buckle, ensuring correct wearing and return through a control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If helmet detection and monitoring systems are added to ensure correct wearing, then helmet wearing compliance and safety are improved, but device complexity increases
Solution Approach 1:
The helmet system is divided into multiple independent detection modules: a first detection module for lock connection state, a second detection module for wearing state, and a third detection module for buckle engagement state. Each module independently monitors a specific aspect, and their results are combined by a control module to determine overall compliance. This segmentation allows the complex monitoring task to be broken down into manageable, specialized components.
Solution Approach 2:
The smart helmet system serves multiple functions within a single integrated platform: it monitors lock connection, detects whether the helmet is worn, tracks buckle engagement, and provides overall compliance determination. This multi-functionality reduces the need for separate systems while achieving comprehensive helmet wearing verification.
2Measurement precision
If multiple detection modules are used to monitor helmet connection, wearing state, and buckle engagement, then measurement precision of helmet state is improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into three specialized modules: the first detection module uses sensors (such as magnetic sensors or contact sensors) to detect lock connection state with high precision; the second detection module uses pressure sensors or weight sensors to accurately determine wearing state; the third detection module uses magnetic sensors or proximity sensors to detect buckle engagement state. Each module is optimized for its specific detection task, achieving high measurement precision while keeping individual module complexity manageable.
3Reliability
If smart detection systems are integrated into the helmet, then safety monitoring is improved, but weight of the helmet increases
Solution Approach 1:
The heavier electronic components, including the control module, power management unit, and communication modules, are extracted from the helmet body and placed in the transportation vehicle. The helmet retains only the essential detection sensors (magnetic sensors, pressure sensors, proximity sensors) and their associated circuitry, which are lightweight. This extraction reduces helmet weight while maintaining safety monitoring capabilities through the distributed sensor system.

AI summary
The present application provides a smart helmet system, a helmet, and a transportation vehicle. The smart helmet system includes a helmet body, a first detection module, a second detection module, and a third detection module. The helmet body includes a first lock part of a helmet lock and retention straps; the retention straps include a helmet buckle; and a second lock part of the helmet lock is mounted on the transportation vehicle. The first detection module is configured to detect, when working, a connection state between the first lock part and the second lock part and send information of the connection state to a control module. The second detection module is configured to detect a wearing state of the helmet and send information of the wearing state to the control module. The third detection module is configured to detect an engagement state of the helmet buckle and send information of the engagement state to the control module. The control module is configured to determine the wearing/return state of the helmet based on the information of the connection state, the information of the wearing state, and the information of the engagement state.
