Retractable Visor Helmet with Dual-Axis Pivot and Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective helmets often have visors or face protection shields that are not readily removable or movable between retracted and extended positions, limiting their functionality and ease of use.
Innovation Solution
A protective helmet design featuring a retractable and removable visor with multiple components, including an anchor block, retainer, and latch system, allowing the visor to be securely attached and easily moved between retracted and extended positions, and removable for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the visor is made securely attached to the helmet, then the reliability of the visor attachment is improved, but the ease of operation for moving or removing the visor deteriorates
Solution Approach 1:
The visor attachment system transitions from a static fixed connection to a dynamic adjustable connection. The latch mechanism allows the visor to be securely locked in an extended position for protection, while enabling easy retraction into the helmet when not needed, providing both security and ease of operation through controlled state changes
Solution Approach 2:
The visor attachment system is divided into separate functional components: an anchor block mounted on the helmet, a retainer with groove and slots, and a latch mechanism. This segmentation allows each component to perform its specific function independently while working together to achieve both secure attachment and easy movability
2Ease of repair
If the visor is designed to be removable for replacement, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The visor is designed as a separate removable component from the helmet, with the attachment system divided into distinct parts (anchor block, retainer, latch). This segmentation enables the visor to be easily removed and replaced without affecting the helmet structure, improving ease of repair while keeping the added complexity manageable through modular design
Solution Approach 2:
The visor attachment mechanism is extracted as a separate, self-contained system that can be independently removed from the helmet. The retainer and latch components are designed to release the visor completely from the helmet structure, allowing for easy replacement while isolating the complexity to a removable subsystem

AI summary
A protective helmet adapted to receive and protect a head of a wearer comprises: an outer shell shaped to protect the head of the wearer, with the outer shell defining a bottom opening and an internal cavity for receiving the head of the wearer; a headband and a suspension positioned within the internal cavity of the outer shell; and a visor rotatable between a retracted position within the outer shell to an extended position in front of a face of the wearer, wherein the visor simultaneously rotates about a first pivot axis and a second pivot axis as it moves between the retracted position and the extended position. The visor can also be readily removed from the protective helmet and easily replaced should it become damaged.
