Helmet Visor Mounting with Elastic Anchors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visor systems for helmets often protrude beyond the helmet's front surface, creating clearance issues for additional equipment and allowing unwanted materials to enter between the visor and the user's face, and they lack adjustable tension for secure mounting.
Innovation Solution
A visor system with a lens that does not protrude beyond the helmet's front surface, featuring a frame secured to the helmet via flexible attachments and anchors, allowing for adjustable tension and easy mounting/dismounting without tools, using elastic cords and hooks/loops for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the visor protrudes beyond the helmet's front surface, then the user has better visibility and protection, but it creates clearance issues for additional equipment and allows unwanted materials to enter between the visor and the user's face
Solution Approach 1:
The visor is nested within the helmet structure by positioning it at or slightly behind the front surface of the helmet, allowing the visor to be contained within the overall helmet envelope. This nesting approach provides eye and face protection while maintaining clearance for additional equipment mounted on the helmet exterior.
Solution Approach 2:
The sealing mechanism addresses the gap problem by adding a dimensional element (seal) that extends from the visor toward the user's face, creating a barrier in the third dimension without requiring the visor to protrude forward. This allows protection from unwanted materials entering through gaps while maintaining compatibility with additional equipment.
2Reliability
If the visor is securely mounted to the helmet, then the visor remains stable during use, but it requires complex fastening mechanisms and tools for mounting/dismounting
Solution Approach 1:
The mounting system is segmented into separate components: a frame with attachment points, flexible attachments (bands or straps), and fastening mechanisms. This segmentation allows the visor to be securely mounted while enabling easy attachment and detachment by simply connecting or disconnecting the flexible attachments from the frame, eliminating the need for tools.
Solution Approach 2:
The flexible attachments (elastic bands or adjustable straps) provide dynamic mounting that adapts to different helmet shapes and sizes. These flexible elements maintain secure mounting through elastic tension or adjustable fastening while allowing quick connection and disconnection without complex mechanical fastening mechanisms.
3Device complexity
If the visor uses fixed tension mounting, then the structure is simpler, but it cannot accommodate different helmet sizes and shapes
Solution Approach 1:
The mounting structure incorporates flexible attachments such as elastic bands or adjustable straps that can dynamically adapt to different helmet sizes and shapes. These flexible elements maintain appropriate tension across various configurations while keeping the overall mounting structure relatively simple, avoiding the need for complex adjustable mechanisms.
Solution Approach 2:
The flexible attachments allow for parameter changes in tension and positioning to accommodate different helmet geometries. By varying the tension and length of the flexible bands or straps, the same mounting structure can securely fit various helmet sizes and shapes without requiring multiple different mounting systems.

AI summary
A visor system for a helmet includes a lens sized to extend across at least a portion of a user's face, a frame secured along a top portion of the lens and configured to receive and abut against a front surface of the helmet, a first fastener coupled to a first end of the frame by a first flexible attachment, and a second fastener coupled to a second end of the frame by a second flexible attachment. The visor system may further include a first anchor releasably securable to the first fastener, the first anchor being mountable onto a first portion of the helmet, and a second anchor releasably securable to the second fastener, the second anchor being mountable onto a second portion of the helmet.
