Motorcycle Garment with Automatic Crash Detection and Activity Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In single vehicle motorcycle accidents, especially in remote areas, riders may remain unconscious for hours before help arrives due to the need for manual activation of emergency beacons, which is inefficient and often results in unnecessary emergency services being dispatched for minor incidents.
Innovation Solution
A garment with integrated sensors, an electronic processing unit, and a communication system that automatically detects crashes and assesses the rider's activity level to decide on emergency assistance, using a smartphone or cellular phone to send alerts only when necessary, and includes an inflatable airbag for impact protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual emergency beacon is used, then the rider can activate help when conscious, but the rider cannot activate help if unconscious or physically unable to reach the device
Solution Approach 1:
The system automatically detects crashes through sensors and triggers emergency communications without requiring rider intervention. The garment monitors the rider's state and autonomously activates help when a crash is detected and the rider remains immobile, eliminating the need for manual activation while maintaining reliability.
Solution Approach 2:
The patent replaces manual mechanical activation with electronic sensor-based detection. Accelerometers and other sensors automatically detect crash forces and rider immobility, substituting the mechanical action of reaching for and pressing a button with electronic detection and automatic system response.
2Extent of automation
If automatic crash detection is implemented, then help can be called without rider input, but emergency services may be dispatched for minor incidents causing resource waste and rider embarrassment
Solution Approach 1:
The system continuously monitors rider movement through sensors after detecting a crash. If the rider remains immobile beyond a threshold period, the system triggers emergency communications. This feedback mechanism allows the system to distinguish between minor incidents where the rider can move and serious incidents requiring emergency response, preventing false alarms while maintaining automation.
Solution Approach 2:
The emergency activation threshold is dynamic rather than static. The system adjusts its response based on the duration of rider immobility after a crash, using time-based criteria to determine whether to activate emergency services. This dynamic approach prevents premature activation for minor incidents while ensuring timely response for serious accidents.
3Reliability
If emergency services are dispatched for every detected crash, then all potential emergencies are covered, but resources are wasted on minor incidents and riders experience embarrassment
Solution Approach 1:
The system uses continuous feedback from movement sensors to assess the severity of each incident. By monitoring whether the rider moves after a crash and using this information to决定是否 activate emergency services, the system maintains comprehensive coverage for serious incidents while filtering out minor incidents that would cause resource waste and rider embarrassment.
4Reliability
If a specialized emergency beacon is used, then dedicated emergency functionality is provided, but the cost is notably higher compared to using a cellular phone
Solution Approach 1:
The system uses a multi-functional approach by leveraging the rider's existing smartphone for emergency communications rather than requiring a specialized beacon device. The garment integrates with universal devices like smartphones and cellular phones, eliminating the need for expensive dedicated emergency beacons while maintaining reliable emergency functionality through the garment's sensor and communication system.

AI summary
A garment (12) is intended to identify a danger situation for the user and react. The garment comprises an emergency device (13) provided with sensors. Furthermore, the emergency device comprises an electronic processing unit (16) and a supervisor and communication unit (17). The supervisor and communication unit (17), after being informed of the danger situation by the electronic processing unit, monitors the user by means of the sensors and assesses the level of user activity in order to decide or not to call for further assistance.
