Solution Overview
Problem
Current concussion detection systems rely on qualitative analysis, leading to subjective interpretation and errors in identifying concussions, particularly in high-pressure sports environments, where athletes may be kept in the game despite significant injuries.
Innovation Solution
A concussion detection and communication system featuring electronic modules mounted on sports helmets, equipped with three-axis accelerometers and a controller, capable of calculating linear and angular acceleration vectors, comparing them to thresholds, and transmitting data for real-time analysis and alerts, facilitating objective concussion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If qualitative analysis is used for concussion detection, then the system is simpler to implement, but the measurement precision and reliability of concussion identification deteriorates due to subjective interpretation
Solution Approach 1:
The patent replaces the mechanical/subjective assessment system with an electronic sensor-based system. Accelerometers and gyroscopes mounted in helmets objectively measure head acceleration and rotational velocity, eliminating reliance on subjective observer judgment and providing quantifiable concussion data.
Solution Approach 2:
The patent introduces electronic sensors and data processing systems as intermediaries between the concussive event and the detection outcome. The sensors capture physical parameters, and the system processes this data to objectively determine concussion occurrence, removing the intermediary of human subjective judgment.
2Reliability
If real-time concussion detection and transmission is implemented, then the reliability of immediate concussion identification improves, but the use of energy and device complexity increases
Solution Approach 1:
The system employs periodic transmission of concussion data at predetermined intervals rather than continuous transmission. This approach maintains reliable real-time monitoring capability while significantly reducing energy consumption by keeping the system in low-power states between transmission cycles.
Solution Approach 2:
The system changes operational parameters dynamically, switching between active sensing and low-power states. The accelerometers and transmitters operate in periodic cycles, adjusting their activity levels to balance detection reliability with energy conservation throughout the monitoring period.

Data Source
AI summary
A concussion detection and communication system is described. In some examples a concussion data module may be worn by one or more subjects. Each concussion data module may include multiple accelerometers and may communicate data signals wirelessly to a base unit. Upon determining that the base unit is not within effective communication range, a concussion data module may relay signals to the base unit through another concussion data module.
