Helmet Mouth Vent Segmentation for Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with mouth vents face difficulties in removing foreign materials like mud and dust due to the complexity of separating the vent body from the chin guard.
Innovation Solution
A helmet design featuring a chin guard with first and second fastening portions and a vent body with corresponding protrusions and fixing means, allowing for easy attachment and detachment, enabling the removal of foreign materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mouth vent is completely fixed to the chin guard, then the structural strength and stability are improved, but the ease of operation for removing foreign materials deteriorates
Solution Approach 1:
The vent body is divided into a detachable vent cover and a vent body main portion. The vent cover can be separated from the chin guard to remove foreign materials, while the vent body main portion remains fixed to maintain structural strength. This segmentation allows the system to have both strong fixation and easy maintenance capabilities.
2Ease of operation
If the vent body is made detachable from the chin guard, then the ease of operation for cleaning is improved, but the device complexity increases
Solution Approach 1:
The vent system is segmented into a vent cover and vent body main portion with a simple detachment mechanism. The fastening portion uses basic mechanical elements (protrusions and recesses) that are easy to assemble and disassemble, avoiding complex mechanisms while still providing detachable functionality for cleaning purposes.
3Reliability
If the vent body is completely fixed to the chin guard, then the reliability of the vent structure is improved, but the productivity for maintenance operations deteriorates
Solution Approach 1:
The vent cover is segmented from the vent body main portion, allowing quick removal for maintenance while the vent body main portion remains reliably fixed to the chin guard. This segmentation enables rapid cleaning operations without compromising the overall structural reliability of the vent system during normal operation.
