Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective helmets do not effectively enhance the communication range of mobile devices due to their small antennas, which limits the performance of connected Bluetooth devices.
Innovation Solution
Integration of an elongated antenna within the helmet's molded lining or foam element, strategically positioned above the ear, to improve reception capabilities by providing additional length and support for mobile communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If mobile devices use small antennas to maintain portability, then device portability is improved, but communication range deteriorates
Solution Approach 1:
The patent combines the antenna with the helmet structure, integrating the antenna into the helmet's molded lining or foam element. This merging allows the antenna to be part of the protective gear rather than a separate mobile device component, enabling longer antenna length without compromising the portability of the mobile device itself.
Solution Approach 2:
The helmet acts as an intermediary between the mobile device and the environment, providing a platform for the antenna. The connection point on the helmet serves as an interface that links the mobile device to the elongated antenna, allowing the antenna to extend beyond the constraints of the mobile device's form factor.
2Length of stationary object
If antenna length is increased to improve communication range, then communication range is improved, but device complexity increases
Solution Approach 1:
The helmet serves multiple functions: it provides head protection and simultaneously houses the antenna system for improved communication. The molded lining or foam element both cushions the head and supports the antenna, eliminating the need for a separate antenna structure and reducing overall system complexity.
Solution Approach 2:
The patent changes the physical parameters of the antenna by embedding it within the helmet's existing structural materials. The antenna is positioned within the molded lining or foam element, utilizing the helmet's three-dimensional space to achieve optimal antenna length and orientation without adding external complexity.
3Length of stationary object
If antenna is positioned above the ear for optimal performance, then communication range is improved, but ease of operation deteriorates
Solution Approach 1:
The antenna is positioned in the vertical dimension above the ear, utilizing the three-dimensional space of the helmet rather than horizontal placement. This vertical positioning optimizes the antenna's electrical length and radiation pattern while keeping the connection point accessible at the helmet's periphery for easy device attachment.
Solution Approach 2:
The connection point is pre-positioned on the helmet at an accessible location, allowing users to easily connect their mobile devices without requiring complex alignment or adjustment. The antenna system is pre-configured within the helmet structure, so users simply need to plug in their device to benefit from the optimized antenna performance.

AI summary
An enhanced protective helmet includes in one embodiment an outer shell and a molded lining disposed within the outer shell and contoured to surround a human head. The helmet further includes an elongated antenna having a proximal end and a free end, the antenna being supported by the molded lining. The helmet includes a connection point which can be mounted to the molded lining or otherwise extend away from the proximal end of the antenna, the connection point communicatively connected to the proximal end of the antenna. The connection point receives a connection from a mobile communication device, thereby linking the mobile communication device and the antenna. The antenna is located at helmet location that is along one side of the helmet above a left or right ear of the user for optimizing antenna performance.
