Head-Mounted Protection Apparatus with Binaural Collision Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective helmets do not provide a proactive warning system to predict potential accidents, limiting the user's field of view and ability to recognize risks during travel, and thus do not effectively prevent collisions.
Innovation Solution
A user head-mounted protection apparatus that includes a warning element management device to identify nearby objects, a sensor to detect head rotation, a corrector to adjust warning element location information, and a sound source processor to output binaurally rendered sounds, enhancing the user's awareness of potential collision directions through a combination of sound and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective helmet is worn to provide safety protection, then the user's head is protected from shock during collision, but the user's field of view is limited and the ability to observe or predict risks is reduced
Solution Approach 1:
The patent introduces an intermediary system consisting of sensors, processors, and output devices that mediate between the external environment and the user. Sensors detect objects and risks in the environment, the processor analyzes this data to identify collision risks, and output devices (visual displays, auditory signals, vibrational alerts) present this information to the user, compensating for the limited field of view caused by the helmet structure.
2Reliability
If a protective helmet is worn to provide safety protection, then the user's head is protected from shock during collision, but the helmet cannot predict accidents in advance or notify the user of potential risks
Solution Approach 1:
The patent implements preliminary action by detecting potential collision risks before actual collision occurs. The sensor continuously monitors the environment for objects or conditions that may lead to collision, the processor predicts potential accident scenarios based on this data, and the system notifies the user in advance through visual, auditory, or vibrational alerts, allowing the user to take preventive action before the collision happens.
Solution Approach 2:
The patent establishes a feedback loop where sensors continuously gather environmental data, the processor analyzes this information to assess collision risks, and the system provides real-time feedback to the user through various output devices. This closed-loop system enables continuous monitoring and immediate notification of potential risks, allowing the user to respond dynamically to changing conditions.
3Device complexity
If conventional protective helmets are used, then the structure remains simple and lightweight, but the helmet lacks proactive warning functions and collision prediction capabilities
Solution Approach 1:
The patent applies multi-functionality by integrating multiple functions into a single helmet system. The helmet not only provides its traditional protective function but also incorporates sensing capabilities to detect environmental objects, processing capabilities to analyze collision risks, and multiple output mechanisms (visual displays, auditory signals, vibrational alerts) to communicate risks to the user, transforming a single-function protective device into a multi-functional safety system.

AI summary
Disclosed is a user head mounted protection apparatus. The user head mounted protection apparatus includes a warning element management device that identifies a warning element by using sensing information generated by sensing a nearby object to generate location information of the warning element, a sensor that detects a rotation of the user head mounted protection apparatus to generate rotation angle information, a corrector that corrects the location information of the warning element by using the rotation angle information, a sound source processor that binaurally renders a sound source by using the location information of the warning element or the corrected location information, and an output device that outputs the binaurally rendered sound source.
