Helmet Goggle Attachment with Asymmetric Sliding Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmet goggle attachment systems, such as those using Velcro hook and loop fasteners, are prone to detachment in adverse weather conditions and do not effectively prevent goggles from sliding over the helmet's surface, leading to discomfort and potential damage.
Innovation Solution
A mechanical gripping system with a sliding stop mechanism that securely attaches goggles to a helmet, ensuring they remain in place without sliding, featuring easily removable and more secure connectors on either side, with one side designed for easy detachment and the other for secure positioning using protrusions and attachment supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Velcro hook and loop fasteners are used to attach goggles to helmet, then easy attachment and detachment is achieved, but reliability deteriorates in adverse weather conditions
Solution Approach 1:
The attachment system is divided into two distinct sides: a first side with easy-release features for convenient detachment, and a second side with secure retention features for reliable attachment. This segmentation allows each side to optimize for its specific function, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
Different attachment mechanisms are applied to different locations (sides) of the goggle-helmet system. The first side uses features optimized for easy detachment, while the second side uses features optimized for secure retention, allowing local optimization of properties to resolve the global contradiction.
2Adaptability or versatility
If goggles are allowed to rotate to various positions on helmet, then adaptability is improved, but harmful factors increase due to sliding and becoming difficult to reach
Solution Approach 1:
The system preemptively prevents harmful sliding by incorporating a stop mechanism on the second side that limits the rotation range. This preliminary anti-action counteracts the potential harmful effect of uncontrolled sliding while preserving the beneficial adaptability of multi-position positioning.
Solution Approach 2:
The attachment system allows dynamic positioning of goggles at various angles on the helmet surface, enabling the user to adjust the goggle position according to different activity requirements while maintaining secure attachment at each position.
3Ease of operation
If one side is designed for easy removal while the other remains connected, then ease of operation is improved, but reliability deteriorates due to potential detachment
Solution Approach 1:
The attachment system is divided into two distinct sides: a first side with easy-release features for convenient detachment, and a second side with secure retention features for reliable attachment. This segmentation allows each side to optimize for its specific function, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The two sides of the attachment system are deliberately made asymmetric in their attachment mechanisms. The first side features are designed for easy release, while the second side features are designed for secure retention, creating an asymmetric system that simultaneously achieves both ease of operation and reliability.

AI summary
A support and attachment system for helmet goggles is described. The main purposes of such a system are to provide an easy attaching of goggles to a helmet and to block the sliding movement of goggles over the outside surface of a helmet by a sliding stop. The support and attachment system for helmet goggles includes two strap connectors each being configured to be attached, on each respective side of the helmet, to the free ends of the goggles' straps and to engage, two attachment supports disposed on the opposite sides of a helmet. One of the strap connectors is adapted to be easily removable while the second is configured to be somewhat difficult to remove. The attachment support connected to the second strap connector includes a sliding stop to block the sliding movement of the goggles when positioned on the top of the outside surface of the helmet.
