Modular Headwear Liner for Helmet Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety helmets face challenges in integrating sensors for force and physiological data collection, and they often lack compatibility with various helmets, leading to increased costs and limited data collection effectiveness.
Innovation Solution
A headwear liner with an array of force detection sensors and temperature sensors, coupled with a control unit for data storage and transmission, designed to be worn under or attached to protective headgear, allowing for comprehensive data collection and compatibility with different helmets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated with protective headgear articles, then force and physiological data can be collected, but the integration process becomes difficult and unpredictable
Solution Approach 1:
The system divides the protective headgear into modular components: a base protective helmet and a separate electronic assembly that can be independently attached. The electronic assembly contains all sensors and processing units as a self-contained module, simplifying integration while maintaining reliable data collection capabilities.
Solution Approach 2:
A control unit serves as an intermediary between the various sensors (force sensors, temperature sensors, accelerometers) and the data transmission system. This central controller coordinates sensor operations, processes signals, and manages data flow, making the overall system more predictable and easier to integrate.
2Adaptability or versatility
If conventional headwear articles are used, then compatibility with various helmets is limited, but costs increase
Solution Approach 1:
The electronic assembly is designed with universal attachment mechanisms that can be adapted to multiple helmet types and sizes. The modular design allows the same sensor package to be mounted on different protective headgear articles, enhancing compatibility across various sports and construction helmets without requiring custom manufacturing for each helmet type.
3Loss of information
If multiple sensors are integrated into protective headgear, then comprehensive data can be collected, but the headwear article becomes less comfortable
Solution Approach 1:
Sensors are strategically positioned at specific locations on the helmet where they can capture necessary physiological and impact data while minimizing contact with the wearer's skin. Force sensors are placed on the helmet's impact surfaces, temperature sensors on non-intrusive areas, and accelerometers at the helmet's center of gravity, ensuring comprehensive data collection while maintaining wearer comfort.
