Helmet Shell Recessed Electronic Connector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective helmets for flight personnel face discomfort and reduced protection due to the bulkiness and protrusion of electronic connecting devices, which also increase the risk of catching on external objects and damaging cables.
Innovation Solution
The integration of an electronic connecting device into the helmet's shell, with a recessed opening extending through both sides, reduces bulk and protrusion, enhancing comfort and protection while minimizing the risk of external interactions, and includes articulating means for accessories like night vision devices to prevent cable pulling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electronic connecting device is mounted on the inner side of the shell with a cavity in the cap, then the device can be housed, but the helmet becomes uncomfortable and protection is degraded
Solution Approach 1:
The electronic connecting device is extracted from the traditional inner-side mounting location and repositioned to the outer surface of the shell. This extraction eliminates the need for a large cavity in the cap, thereby maintaining wearer comfort and helmet protection while still providing housing for the electronic device through the outer surface mounting structure
2Ease of manufacture
If the connecting device is removably mounted on the outer surface of the shell, then the device can be attached, but it forms a protruding member that can catch on outside elements
Solution Approach 1:
The connecting device incorporates articulating means that allow it to move dynamically between a protruding position (when not in use) and a retracted position (when in use). This dynamic capability reduces the catching risk by allowing the device to conform to the helmet's contour or retract into a less prominent position, while still enabling secure attachment and cable management when needed
3Ease of manufacture
If the connecting device is mounted on the outer surface, then the device can be attached, but cables positioned outside the helmet risk catching and damaging interactions
Solution Approach 1:
The cable routing system is nested within the helmet structure, with cables passing through the shell and connecting device housing rather than extending externally. This nesting arrangement protects cables from external damage and catching risks while maintaining electrical connectivity between the electronic device and external power sources
