Biometric Sensor Assembly Integrated Into Hardhat Suspension Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional helmets lack integrated biometric sensing capabilities to monitor wearer health and safety in hazardous environments, failing to provide real-time feedback or alerts for potential health deviations during wear.
Innovation Solution
A biometric sensor assembly is integrated into a hardhat's suspension harness, enabling direct or indirect contact with the wearer for data measurement, with electrical connections for data and power transmission, and including features like haptic feedback and visual/audio alerts for significant biometric deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional helmets are used without integrated sensors, then the device complexity is low and ease of manufacture is high, but the ability to monitor wearer health and provide real-time safety feedback is absent
Solution Approach 1:
The patent combines biometric sensors, electrical connections, and feedback mechanisms with the traditional hardhat structure. The sensors are integrated into the suspension harness, electrical connections are built into the hardhat body, and feedback devices (lights, speakers) are mounted on the hardhat, creating a unified safety monitoring system that resolves the contradiction between added functionality and device complexity
Solution Approach 2:
The hardhat is transformed from a single-function protective device into a multi-functional system that simultaneously provides physical protection, biometric monitoring, data transmission, and real-time safety feedback. This universal approach allows one device to serve multiple purposes, improving wearer safety while managing complexity through integrated design
2Reliability
If biometric sensors are integrated into the hardhat, then real-time biometric monitoring is achieved, but the ease of manufacture decreases due to integration requirements
Solution Approach 1:
The system is divided into separate functional modules: biometric sensors attached to the suspension harness, electrical connections integrated into the hardhat structure, and feedback mechanisms mounted on the hardhat. This segmentation allows each component to be manufactured and tested independently before assembly, improving ease of manufacture while maintaining real-time monitoring capability
Solution Approach 2:
The suspension harness acts as an intermediary component that carries the biometric sensors and provides a mounting structure for electrical connections. This intermediary approach simplifies integration by using an existing structural element (the harness) to support the sensing components, rather than requiring direct integration into the hardhat shell

AI summary
A biometric sensor assembly measures biometric data of a wearer of a hardhat. The biometric sensor assembly includes a suspension harness to be removably secured to the hardhat. A biometric sensor is attached to the suspension harness in a way that allows direct or indirect contact with the wearer to enable measurement of the biometric data. The biometric sensor assembly also includes an electrical connection of the biometric sensor and the hardhat for data and power transmission.
