Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visor coupling and locking mechanisms for helmets are complex, with too many parts, and do not ensure easy removal or secure attachment, especially during impacts or racing environments.
Innovation Solution
A visor lateral coupling mechanism with a base, actuator, and guide member that allows quick and secure attachment and removal of the visor, using an ejection flange and resilient components to facilitate easy operation and prevent accidental detachment, along with a visor front locking mechanism for secure riding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex visor coupling and locking mechanisms are used, then secure attachment is improved, but device complexity increases
Solution Approach 1:
The visor coupling mechanism is divided into separate functional components: lateral coupling assemblies at the sides of the visor and a front locking mechanism. Each component performs a specific function, allowing the system to achieve reliable attachment through modular simplicity rather than complex integrated mechanisms.
Solution Approach 2:
The lateral coupling assemblies and front locking mechanism work together as an integrated system where the coupling ribs engage with guiding spaces and the locking mechanism secures the visor in the closed position. This combination of simple elements achieves secure attachment without requiring complex individual components.
2Ease of operation
If rapid visor removal is implemented, then ease of operation is improved, but reliability of attachment may worsen
Solution Approach 1:
The lateral coupling assemblies are pre-positioned with coupling ribs that align with guiding spaces in the helmet shell. This preliminary alignment allows the visor to be quickly attached and removed without requiring complex alignment procedures, while the pre-positioned front locking mechanism ensures secure attachment when closed.
Solution Approach 2:
The coupling ribs act as intermediary elements between the lateral coupling assemblies and the helmet shell, facilitating quick attachment and removal through simple insertion and extraction motions. The front locking mechanism serves as an intermediary that secures the visor in the closed position without requiring complex locking procedures.
3Reliability
If prevention of accidental detachment is enhanced, then reliability is improved, but device complexity increases
Solution Approach 1:
The front locking mechanism is designed to automatically engage when the visor is closed, creating a preliminary locking action that prevents accidental detachment. The locking ribs and guiding spaces are configured to automatically secure the visor without requiring additional complex locking procedures or user intervention.

AI summary
It comprises a helmet shell (2), a visor (1) and a lateral mechanism (10) for coupling the visor (1) to and removing it from the helmet shell (2). The visor coupling mechanism (10) comprises a base (20) coupled to the helmet shell (2) for receiving a portion (1 a) of the visor (1) such that it can be rotated to the helmet shell (2) for opening and closing a helmet shell front opening; an actuator (30) mounted to the base (20) such that it can be moved thereto and be arranged in a visor operating position in which the visor (1) is coupled to the helmet shell (2) and in a visor removable position in which the visor (1) can be removed from the helmet shell (2); a locking flange (35) formed in the actuator (30) for holding the visor (1) coupled to the helmet shell (2) in the visor operating position; and a guide member (40) coupled to the actuator (30) such that it can be moved to the actuator (30) and to the base (20).
