Safety Helmet with Bone Conduction Hazard Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety headgear is reactive and limited to protecting only the head, failing to proactively monitor and alert users of potential hazards in complex environments, which may include fall hazards and objects, and does not provide full-body protection.
Innovation Solution
A safety helmet equipped with a plurality of location transceivers and bone conduction transmitters that monitor the environment, provide directional notifications of potential hazards, and adjust their monitoring area based on the wearer's position and terrain, using adjustable mounts to ensure continuous hazard detection and alerting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hard hats are used, then head protection is provided, but proactive hazard monitoring and alerting capabilities are lacking
Solution Approach 1:
The safety helmet integrates multiple functions including location transceivers for hazard detection, bone conduction transmitters for alerting, and mounting brackets for positioning. This multi-functional integration transforms a simple protective helmet into a comprehensive safety monitoring system that provides both physical protection and proactive hazard warning capabilities.
Solution Approach 2:
The patent combines location transceivers, bone conduction transmitters, and mounting brackets into a single integrated safety helmet system. This merging of components allows the helmet to simultaneously perform protection, detection, and communication functions, resolving the contradiction between reliability and complexity through unified design.
2Reliability
If protective headgear is designed to protect only the head, then head safety is improved, but full-body protection against environmental hazards is limited
Solution Approach 1:
The safety helmet serves as a mobile monitoring station that detects hazards in all directions around the wearer, not just protecting the head physically but providing awareness of environmental hazards including fall risks and objects in the surrounding area, effectively extending protection scope beyond the head.
3Measurement precision
If location transceivers are positioned to monitor a desired area, then hazard detection capability is improved, but device stability and positioning accuracy deteriorate due to head movement
Solution Approach 1:
The system uses multiple location transceivers positioned at different locations on the helmet, each monitoring specific zones. This segmentation allows the system to maintain comprehensive coverage even when individual transceiver positions change due to head movement, as the collective monitoring area remains stable.
Solution Approach 2:
The mounting brackets are designed to be adjustable, allowing the location transceivers to be repositioned to optimize monitoring coverage. This dynamic adjustability compensates for head movement and maintains accurate hazard detection capability throughout various working positions and head orientations.

AI summary
A safety helmet configured to provide notification to a wearer of a potential safety hazard wherein the notification is transmitted via bone conduction and is directionally aligned with the heading of the potential hazard. The safety helmet of the present invention includes a body wherein the body has disposed thereon a plurality of location sensors. The location sensors transmit signals so as to identify potential hazards in the area proximate the user. The location sensors are secured to the safety helmet using brackets wherein the sensor brackets have a first mode and a second mode. The bone conduction transmitters are operable to ensure transmission of a warning sound to a user in noisy environments. An elevation sensor is configured to monitor the height of the wearer respective to a calibrated ground.
