Portable Wearable Device for Collision Detection and Emergency Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices for road traffic safety do not effectively detect emergencies and communicate them to external systems, nor do they provide adequate warnings to users in potentially hazardous situations, such as collisions with vehicles or falls, in a convenient and reliable manner.
Innovation Solution
A portable device equipped with a communication system, position-determining system, evaluation unit, and vibration generator, which can be worn on the body, uses a behavior prediction algorithm to assess collision probabilities and emit warnings or alarm calls via vibrations or communication with external systems, including rescue control centers, when dangerous situations arise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable device is designed to detect emergencies and communicate with external systems, then road traffic safety is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple safety functions (collision detection, fall detection, emergency communication, position determination) into a single portable device that can be worn on the body. This integration resolves the contradiction by consolidating complex functionality into one unified system rather than requiring multiple separate devices.
Solution Approach 2:
The portable device is designed with multi-functionality to handle various emergency scenarios including road collision detection, fall detection, and general emergency communication. This universal design allows one device to address multiple safety concerns, improving overall road traffic safety without requiring users to carry or manage multiple specialized devices.
2Reliability
If the device provides timely warnings and automatic alarm calls, then user safety is improved, but the ease of operation may deteriorate due to automated detection requirements
Solution Approach 1:
The device performs preliminary detection and assessment of dangerous situations automatically before an emergency occurs. The behavior prediction algorithm continuously monitors position data and detects potential collision risks in advance, allowing the system to prepare and issue warnings proactively rather than waiting for the emergency to fully develop.
Solution Approach 2:
The portable device operates autonomously by automatically detecting emergencies, determining their nature (collision, fall, etc.), and initiating appropriate alarm calls without requiring user intervention. The system serves itself by processing position data, evaluating dangerous situations, and communicating with external systems independently, which improves user safety while minimizing the operational burden on users.
3Measurement precision
If the device uses behavior prediction algorithms for collision detection, then measurement precision of dangerous situations is improved, but the loss of computational energy increases
Solution Approach 1:
The behavior prediction algorithm processes position data selectively to detect dangerous situations rather than continuously analyzing all possible parameters at maximum detail. The system applies computational resources proportionally to the detected risk level, performing more intensive analysis only when potential hazards are identified, thus balancing measurement precision with energy consumption.

AI summary
A portable device for increasing road traffic safety, detecting emergencies and emitting an alarm call for a person. The portable device includes a communication device, a position-determining system, an evaluation unit and a vibration generator. The portable device communicates, by way of the communication device, with at least one further communication device of at least one external system. The person is warned by the vibration generator of a dangerous situation determined by the evaluation unit in combination with the position-determining system and the communication device. The dangerous situation is a collision of the person wearing the portable device with the at least one external system that includes the at least one further communication device. This collision is determined by way of a behavior prediction algorithm. When the, or a further dangerous situation arises, the portable device emits an alarm call by way of the communication device.
