Helmet Face Protection Accessory With Removable Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face protection accessories for helmets are bulky, leading to increased encumbrance and storage space requirements, as they often have integral engagement portions that make it necessary to have multiple helmets for different tasks or a set of accessories for various needs.
Innovation Solution
A face protection accessory with a support structure that allows for the engagement and removal of different face protection structures, utilizing switchable coupling means with rotatable coupling pins and locking mechanisms, reducing the need for bulky engagement portions on each individual accessory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face protection accessories have integral engagement portions for coupling to helmets, then they can be securely attached, but the encumbrance and storage space requirements increase significantly
Solution Approach 1:
The invention divides the face protection accessory into two separate components: a support structure with engagement portions and a detachable face protection element. This segmentation allows the face protection element to be stored separately from the bulky engagement portions, significantly reducing storage space requirements while maintaining secure attachment when in use
Solution Approach 2:
The invention extracts the engagement portions from the face protection element itself and places them on a separate support structure. This extraction eliminates the need for each face protection element to have its own engagement portions, reducing the volume of individual accessories that need to be transported and stored
2Adaptability or versatility
If multiple face protection accessories are equipped for different tasks, then task-specific protection is achieved, but the overall encumbrance and transport difficulty increase
Solution Approach 1:
The invention creates a universal support structure with standardized engagement portions that can accommodate multiple different face protection elements. This multi-functionality allows a single support structure to serve various tasks by simply changing the face protection element, eliminating the need for multiple complete accessories and improving transport convenience
3Adaptability or versatility
If face protection accessories can be temporarily applied and removed, then versatility is improved, but bulky engagement portions are required on each accessory
Solution Approach 1:
By segmenting the accessory into a permanent support structure with engagement portions and a removable face protection element, the invention allows mounting flexibility while concentrating the engagement mechanisms in a single location rather than distributing them across multiple complete accessories
Solution Approach 2:
The invention merges the engagement portions with the support structure rather than with each individual face protection element. This combining reduces the volume of each removable accessory while maintaining the ability to be temporarily applied and removed

AI summary
A face protection accessory for work or sports protective helmets is disclosed. The accessory has a support structure having two engagement portions for its engagement to an outer surface of a helmet and a face protection structure, transparent or perforated, to allow a user wearing the helmet to see through the latter. The face protection structure is engageable to the support structure and is removable from the support structure to remove the face protection structure from the helmet or to replace the face protection structure with another different face protection structure.
